Kodiak Recirculating Chiller Technical Manual

GENERAL INFORMATION
Chiller System Description
Your chiller consists of a refrigeration system, a coolant loop, associated controls and plumbing. The
pump draws coolant from the internal reservoir and pumps it out to cool the process equipment, and
then the coolant flows back to the chiller. The fluid then flows through the evaporator, where the heat is
removed, and then back to the reservoir.

Coolant Loop
Kodiak chillers are designed to operate with continuous coolant flow through a closed loop. This loop
contains the system pump, temperature sensor, reservoir, internal and external plumbing lines and
fittings, and the external heat load. The external plumbing and the heat loads are provided by the end
user and are generally unique to the user’s process or location.

Refrigeration System and Hot Gas Bypass
The chiller uses a standard refrigeration system to keep the coolant at the process temperature set
point. The compressor compresses the refrigerant vapor. The vapor then passes through the
condenser where it is cooled and turns to a liquid. The refrigerant then passes through the evaporator.
The coolant also flows into the evaporator, through passages separated by thin layers of metal from the
refrigerant. The refrigerant evaporates, drawing heat from the coolant. The refrigerant vapor returns to
the compressor and continues the cycle.
Many refrigeration systems, such as those used in household refrigerators, control the temperature by
turning the compressor on and off. This is a simple, inexpensive method of controlling the cooling, but
its temperature control is not precise and the frequent on-off cycles causes wear on the compressor
motor.
Lytron’s recirculating chillers use a better method for controlling the cooling rate: a hot-gas bypass
system. This employs a liquid line solenoid valve and a hot-gas bypass valve to meter the refrigerant
flow through the evaporator when cooling is needed. When the coolant reaches its set point
temperature, the liquid line solenoid valve closes, causing the hot-gas bypass valve to open. The hotgas valve lets hot gas from the compressor discharge into the evaporator, adjusting the temperature in
the evaporator to maintain the correct coolant temperature. When refrigeration is needed the liquid line
solenoid valve opens, the hot-gas valve closes and the cycle starts again.
This hot gas bypass control method provides precise temperature control. It also minimizes wear on
the compressor motor, since the compressor runs continuously and does not experience the stress of
repeated cycling.

OPTIONAL SYSTEM FEATURES
Coolant Water Filter
The factory installed water filter removes particulate from the coolant water. The water filter is not recommended
with centrifugal pumps or turbine pumps. For replacement filters, call Lytron’s Customer Service at 781-9337300.

Deionization Package
The Deionization Package consists of a factory-installed deionization cartridge. The deionization cartridge
requires replacement only when the mixed bed is depleted. For replacement cartridges, Call Lytron’s Customer
Service at 781-933-7300. This package is offered for deionized water applications where the resistance of the
water does not exceed 1 Mega-ohm-cm. The deionization package is not recommended with centrifugal pumps.

External Customer Contacts
This option will send a signal indicating there is a problem with the chiller. It can be wired to open on fault or
close on fault. This connector is located on the rear left of the system. Pin 5 is the common, Pin 6 closes on
fault, and pin 4 opens on fault. The mating connector is Amp part number 350715-1, and the pins for the
connector are Amp part number 350547-1. These contacts are rated for 250 V, ½ amp maximum.

External Manually Adjustable Flow Valve
This option allows the flow rate to the equipment to be controlled with a globe valve. Opening the valve allows
the flow to bypass from the supply to the return. By adjusting the valve a precise flow rate can be set. To be
sure the process equipment is receiving the appropriate flow install a flow meter at the outlet from the process
equipment.

External Pressure Relief Valve
This option is for applications with a maximum allowable pressure. It can also be used where flow to the
equipment being cooled needs to be shut off without stopping the chiller. In this case the pressure relief valve
will open and allow the flow to bypass from the supply to the return. The standard valve has an adjustment
range from 50 psi to 100 psi.

Fault Chiller Shut-off
This option will shut the chiller off in the event that there is an alarm condition. It will turn off the power to the
pump and compressor and give an error signal on the front panel of the chiller. To reset the system after a fault
the main power must be turned off at the circuit breaker.

Heater Package RC011, RC022, RC030 and RC045
The heater package is for applications requiring coolant temperature well above ambient temperature. This
package is a single set point type. The heater is activated when the water temperature is 3qF below set point.
The heater option is not intended to provide tight temperature control, but to bring coolant temperature up to an
application's requirement faster than the refrigeration cycle (hot gas bypass).

High Purity Plumbing
This option is intended for use with deionized water. Only stainless steel and/or plastic components and a
nickel-brazed heat exchanger come in contact with the coolant. This option must be specified before the chiller
is purchased. It cannot be upgraded in the field.

Remote Start
This option allows the Kodiak chiller to be started or stopped through a computer or a relay. The chiller can e
run using a normally open circuit or normally closed. (Look under the section labeled Chiller Operation for more
details) R.S. contacts are located on the rear left of the chiller shown previously. It is a six-pin connector with
pins 1 and 2 controlling R.S. The mating connector is an Amp 350715-1 plastic housing. The pins are Amp
350547-1. The controlling relay should have SPDT type contacts rated for low current less than or equal to
5VDC at 0.1 milliamp.

RS-232 Serial Port Communication
This option allows control of the chiller via a standard 9 pin serial port connected to a computer. Lytron
software is available that simulates the front control panel and all its functions. Alternatively, software can be
created to interface with the system described in the section labeled Host Interface Data Link.

Water Cooled Condenser RC011, RC022, RC030 and RC045
This feature replaces the standard condenser and fan with a water-cooled condenser. This requires cooling
water to be supplied to the chiller at 75qF (25qC). The facility water pressure must be less than 100 psi.
Minimum flow rates are as follows:

Lytron recommends using filtered clean water above 10°C/50°F as coolant.

If the set point is 10°C/50°F or below, a freezing point depressant, such as ethylene glycol,
is required. This unit is equipped with a low flow switch. This feature will shut the chiller down during a low
flow situation to prevent freezing.

Do not use automotive anti-freeze in the chiller. The rust inhibitors in the automotive type
may cause premature failure of the pump seals. Use of automotive anti-freeze in a Lytron chiller will void
the warranty.

Avoid using water with a high mineral content.

If the coolant is exposed to sunlight add an algaecide to control organic growth in lines.

Electrical Requirements (for units without heater option)
Refer to the Specification section and to the product ID label on the rear of the chiller for the specific electrical
requirements of your unit. The chiller power module is configured with a standard international IEC320/C20
inlet. To safely operate the chiller, use an SJT cord set with an IEC 320/C19 receptacle and an inlet plug that is
compatible to the local power grid and the power requirements of the chiller. All Kodiak chillers should use SJT
3 conductor 12 AWG minimum power cord.

Selecting Chiller Location
Do not operate or store Kodiak chillers outside. These systems are not intended for outdoor
use.
To minimize the heat gain and pressure drop through the connecting hoses, the chiller unit should be located as
close as possible to the heat load (user equipment). This is more important for units with centrifugal pumps as
they are not capable of high head pressures. Coolant lines are best run at or near the same level as the cooling
system. Once the chiller is in position lock the casters.
Airflow is critical to optimize performance of the chiller. The front and one side or the back of the unit MUST be
kept clear and unobstructed. The remaining two sides or back must have minimum clearance of 18" (456 mm).
The top clearance must be at least 6" (152 mm). Ensure that the hot air exiting the chiller does not recirculate
into the inlet openings. The front of the unit must have a free supply of ambient-temperature air.
Before moving the chiller cap all ports to prevent any coolant leakage. Unlock the casters and move to new
location. Once in the new location lock the casters. To prevent freezing during storage drain water if the chiller
is located in an area below 10qC (50qF).

INSTALLATION PROCEDURE
Selecting and Locating Hoses
x

The coolant ports are located on the rear of the system and are labeled as previously shown on page 13.

To minimize the pressure loss in the coolant lines, use the largest practical diameter tubing. If substantial
lengths of cooling lines are required, they should be pre-filled with coolant before connecting them to the
chiller.

To minimize heat gain, all lines should be as short as possible. Keep them away from heat sources such as
radiators and hot water pipes. Lines that cannot be routed away from heat sources should be protected
with thermal insulation, preferably at least 1/2" (12.7mm) thick.

Flexible tubing should be of heavy wall or reinforced construction. All tubing should be rated to withstand
125 psig (9 bar) at 86°F (30°C). Make sure all tubing connections are secured and leak-tight. Also,
whenever possible use opaque lines to prevent algae growth during prolonged non-operating periods.

Connecting Plumbing
To connect the fluid lines to the chiller and user equipment follow these steps:
1. Remove the plastic caps covering the supply and return ports on the rear panel of the unit.
2. Attach coolant lines to the supply and return ports on the rear panel. Fittings should either be brass,
Never use steel or cast iron fittings, as the corrosion will damage
stainless steel or nylon.
the chiller. For chillers with de-ionization cartridges or high purity plumbing Lytron recommends the use of
either stainless steel or nylon fittings. The supply port provides chilled coolant to the user’s equipment. The
return port connects to the outlet of the user’s equipment.
3. Check that fittings are tight to prevent leaks.
4. Remove water filler cover on top of the unit to access the reservoir.
5. Fill the reservoir. Use the reservoir sight tube on the front of the unit to see the coolant level in the tank
during filling. Be sure to allow for the volume of coolant needed to fill the cooling lines between the chiller
and the equipment, if they were not filled with coolant before installation.
6. If the system is a water-cooled chiller, connect facility water to connections labeled "City Water In" and "City
Water Out". Minimum flow rate of facility water is shown on page 15. Facility water flow must be started
before chiller is turned on.

PRIMING TURBINE AND CENTRIFUGAL PUMPS
Running centrifugal and turbine pumps dry for even a few seconds can permanently damage
the pump. This style of pump must be “primed” prior to operation.
Pump priming must be performed under the following conditions:
a. At initial start-up.
b. The system is drained of its fluid.
c. A new pump is installed.
x

Centrifugal and turbine pumps are classified as non-self priming pumps. This means that the pump will not
displace the air inside the pump housing, which prevents fluid from being drawn in. Each must be “primed”
prior to operation. “Priming” simply means to manually introduce fluid into the pump housing prior to
operation.

In a typical chiller installation, the flow of fluid through the pump suction hose into the pump is prevented by
the presence of trapped air. Without a way for the air to escape, the fluid has no way of entering the pump
housing. The following are recommended procedures to prime a turbine or centrifugal pump.

a. Valve in open position

b. Valve in closed position

Units equipped with priming valve. – The priming valve circuit is located between the pump
discharge plumbing line and the top of the tank. There is a valve labeled “pump priming valve” located
in this line. To prime the pump simply open this valve prior to starting the chiller (photo a). Start the
chiller. After flow is observed returning to the tank, close the priming valve (photo b).

Units that do not have a priming valve. – To prime pumps that do not have a priming valve,
disconnect the supply line from the rear of the chiller. Allow time for the fluid to gravity feed into the
pump housing. If there is difficulty priming the pump using this method, use a wet vac to assist in
drawing the fluid from the tank into the pump housing.

Note: If the pump has failed to prime turn the chiller off and contact Lytron’s Service
Department - 781-933-7300.

CONNECTING POWER (FOR UNITS WITHOUT HEATER OPTION)
In order to avoid an electrical potential at the chiller frame due to insulation failure, a proper
ground connection to the system must be provided. Failure to do so could result in damage to
the equipment, personal injury, and/or death.
Connect a 3-conductor SJT type power cord with an IEC 320/C19 receptacle to the inlet power to the module
on the rear of the unit and to an appropriate AC power source. All chillers should use a 12-gauge power cord.

Startup Procedure
1. Turn "ON" the circuit breaker on the rear of the unit. The controller will go through a diagnostic test. Turn
on the chiller unit using the top left key located on the Keypad Display panel. The controller displays "OFF"
for 8 seconds. The delay prevents rapid cycling of the compressor using the "ON" and "OFF" switch. If
your chiller is equipped with control package 2 or 3 the fault shut off may prevent the chiller from starting up.
If the chiller displays an alarm after pushing the “ON” button disable the fault shutoff on the customer menu
and restart the chiller.
2. Adjust the temperature set point using the controls on the keypad display as follows:
x Press the “SET” key once to display the current coolant temperature set point.
x Press the “UP” or “DOWN” arrow key until the desired coolant temperature set point appears on the
LED display.
x Press the “SET” key again to accept the set point and return to normal operation.
3. Operate the chiller for a short time and then check the coolant level in the reservoir. If the level drops, add
more coolant.
4. Check all fittings and hoses for fluid leaks. If a leak exists turn chiller off, disconnect power and take
necessary action to repair the leak.

Please Note:
During initial start up the temperature display may occasionally appear to be dim. This is a normal occurrence
and does not indicate that there is problem with the chiller. After 10 seconds the display will brighten to its
normal level.

Kodiak Recirculating Chiller Technical Manual

SYSTEM MAINTENANCE AND SERVICE
A qualified service technician must perform all service and maintenance internal to the chiller.
Unqualified individuals conducting service on the chiller could result in damage to the
equipment, personal injury and/or death.
After your Kodiak Recirculating Chiller is up and running, it takes only a small amount of care and maintenance
to keep it running well.
Every installation is unique, and the operating conditions determine how often the equipment should be
inspected and maintenance be performed. The following are some guidelines.

Periodic Inspections
Noise Level
Any abnormal sounds or a substantial increase in noise level since the last weekly inspection may indicate the
following: impending pump, fan or coolant blockage problem. Investigate the cause and perform the necessary
service. Refer to the troubleshooting guide in this manual.

Leakage
If you notice coolant on the floor near the chiller or dripping from the chiller enclosure turn off the chiller.
Disconnect the power cord. Find and repair any leaks immediately.

Coolant Level
Any significant drop in the coolant level should be investigated further. If there is no visible system leak, then
the loss may be due to equipment leakage elsewhere.

Pump / Motor
Some pumps may require lubrication. If the pump needs lubrication, lubricate annually with 20-30 drops of SAE
Oil.

Fan Assembly
No maintenance is required on the fan. Listen for any abnormal sounds.

Condenser Fin
Remove the front grill by sliding it upward, pulling the bottom out and pulling it straight down. For maximum
performance the condenser fin should be free of dust and debris. Use a vacuum cleaner or compressed air to
remove any debris and keep the fin clean.

Water Filter
With a new system the filter quickly accumulates foreign matter introduced during system setup. This can lead
to a decrease in system performance in a short period of time. Inspect the filter cartridge one day after you set
up a new system to ensure the filter is clean and the system runs at maximum capacity. After this initial filter
inspection, check the filter weekly. For replacement filters contact Lytron’s Customer Service at 781-933-7300.

Deionization Package
The cartridge life is a function of the user’s application. Check the water resistively weekly and change the
cartridge as required. For replacement filters contact Lytron’s Customer Service at 781-933-7300.

Low Level Switch
The level switch protects the pump in the event of accidental fluid loss. Since this switch is "passive" during
normal operation, it is advisable to check it every 6 months. Open the tank cover and push down on the switch
to see if the low level alarm is activated.

Algae
Lytron recommends the use of an algae inhibitor to prevent growth in the reservoir.

Cleaning the System and Reservoir
To clean the unit follow these steps:
1.
2.
3.
4.
5.
6.

Drain the entire unit including the hoses and equipment being cooled.
Replace the coolant with clean water.
Run the unit with the clean water for 10 minutes.
Drain the unit again.
Replace all filters.
Refill unit with either water or a water and freezing point depressant.

Pump Strainer
All positive displacement pumps have a strainer to protect the vanes inside the pump. For pumps less than 2.5
gpm it is located in the pump housing. For larger PD pumps it is installed in the hose between the pump and
the tank. Periodically inspect and clean the pump strainer. If it becomes fouled the flow rate will decrease and
the pump may wear prematurely.
The strainer can be cleaned by rinsing it in warm water and brushing it gently. For a detailed procedure in
cleaning the pump strainer visit the Maintenance and Troubleshooting section of Lytron’s website at
www.Lytron.com.

Pumps
As a precaution, the pump must be periodically replaced. This will avoid damaging the unit and the cost
associated with excessive downtime. Typical operating life of the pump depends on pump type.

DRAINING PROCEDURE FOR KODIAK CHILLERS
Always disconnect power to chiller when performing service. Failure to do so could result in
damage to the equipment, personal injury and/or death.
A container should be available to hold the fluid removed from the chiller. This container
should be labeled in accordance with OSHA rules and regulations concerning handling of the
fluid being removed from the chiller. Failure to do so could result in personal injury.
Reference the MSDS sheet for the fluid being removed from the chiller for further handling,
storage, and disposal instructions. Disposal of fluid removed from the Lytron chiller should be
in accordance with all Local and Federal disposal laws. Failure to do so could result in personal injury.
Not following this procedure may result in extensive damage to the chiller. It is extremely
important to completely drain the chiller when not in use for extended period of time, shipping
outside of its current location, during certain repairs, and for scheduled fluid maintenance. Failure to fully drain
the system could result in damage of the equipment. Lytron recommends method #1 as the most efficient way
to remove fluid from the chiller.
Method #1- Recommended
1. Lytron recommends using a wet/vac to thoroughly remove fluid from the chiller. Remove plastic cap
from top of the clean fluid reservoir. Vacuum this tank until it is completely free of any fluid. Keep
reservoir cap removed from reservoir until step #5.
2. Using wet/vac, first vacuum the “supply” connection located at the rear of the chiller. After all the fluid
has been removed from the supply side, move vacuum to the “return” connection. Vacuum this
connection until all fluid has been removed.
3. Remove side panel of chiller to expose the tank drain hose. The drain line is a ½” braided hose
terminated with a white PVC cap. The drain line branches off from a tee on the chiller return line.
4. Remove plastic cap plug and place vacuum at the end of the hose. Vacuum any remaining fluid from
the system. (Note: make sure reservoir cap is removed, allowing air to enter system).
5. Install plastic cap plug to the end of the drain hose. Install side panel. Attach plastic cap to the clean
fluid reservoir. Install chiller cover.
Method #2- without access to wet/vac
1. Remove chiller cover. Remove reservoir plastic cap. Keep reservoir cap removed from reservoir until
step #4. Remove side panel of chiller to expose the tank drain hose. The drain line is a ½” braided hose
terminated with a white PVC cap. The drain line branches off from a tee on the chiller return line.
2. If possible, elevate the chiller approximately 3’ off the ground. This will allow you to drain the system
into a 5-gallon bucket.
3. Remove the plastic cap plug from the end of the hose. (Note: make sure reservoir cap is removed,
allowing air to enter system). Drain the system into a 5-gallon bucket. Because this process is relying
on gravity, it may take a few minutes to completely drain the system. If the volume of your system
exceeds 5 gallons, have a second bucket nearby.
4. Install plastic cap plug to the end of the drain hose. Install side panel. Attach plastic cap to the clean
fluid reservoir. Install chiller cover.

Kodiak Recirculating Chiller Technical Manual

COOLANT MAINTENANCE
Recommended coolant for use in Lytron systems
x Clean water is recommended for most systems. Systems ordered with the deoinized plumbing package
require that deoinized water be used. Use of deoinized water in systems with brass components may cause
premature failure of the system.
x If the set point temperature is below 50°F/10°C, Ethylene or Propylene Glycol should be added to the water
with a mix ratio of 30% Ethylene or Propylene Glycol to 70% water.
x Do not use automotive antifreeze as the rust inhibitors may cause premature failure of the pump seals.
x Avoid using water with a high mineral content.
x If the chiller is exposed to sunlight, add an algaecide to control organic growth in the coolant. A mixture of
30% Ethylene or Propylene Glycol can also be used to control algae growth.

Checking coolant level
x There is a coolant level site tube on the front of the unit. Coolant should be added as soon as this indicator
approaches the half-full mark.
x Reducing the coolant volume may reduce the chillers cooling capacity.
x Inspect coolant level weekly or whenever the chiller is powered on.

Flush & replace coolant periodically
In order to avoid electric shock, be sure to wipe up all fluid spills in the unit before applying
electrical power. Failure to do so could result in damage to the equipment, personal injury
and/or death.
x Depending on the environmental conditions, the coolant should be flushed and replaced as necessary,
depending on the amount of particulate matter that has been found in the system during planned
maintenance inspections.
x If the pump strainer and coolant is found to have little or no contamination after the first inspection, replacing
the coolant and cleaning the strainer can be done less frequently.
x The pump strainer may be located in one of two places. Refer to the strainer cleaning procedures under
System Maintenance and Service.
x When the strainer is cleaned or replaced, the electrical power must be disconnected and the system drained
of all coolant.

Kodiak Recirculating Chiller Technical Manual

HOST INTERFACE DATA LINK
Control Package 3 only
1.0 Host Interface Data Link
The chiller supports basic host control capability through the Chiller RS-232 port.

1.1 Port Settings
The host port runs at 9600 baud, 8 data bits, 1 stop bit, and no parity.

1.2 Flow Control
The chiller negates the Chiller RTS (output from Chiller) line whenever the Chiller is busy in a non-interruptible
process. The Chiller ignores the Host CTS line. No software (Xon/Xoff) flow control is provided. It is the
responsibility of the host to issue only a single command for which a response from the Chiller Control is
required until the response is received from the Chiller Control. Inter and intra message timeout is defined as 1
second. (Typical response times and character pacing will be baud rate limited.)

1.3 Encoding
All characters are to be ASCII characters. All messages from the host to the control and from the control to the
host will have 0x10 (ASCII Line Feed) as a start-of-message delimiter, and 0x0D (ASCII Carriage return) as an
end-of-message delimiter. Permitted message characters are in the range of 0x20 through 0x7F
(hexadecimal).

1.4 Numeric Representation
Hexadecimal numbers, using ASCII characters ‘0’ – ‘9’ & ‘A’ – ‘F’, will represent all numeric values. When the
Chiller Control returns multiple variables or parameters they will be white space separated (using ASCII 0x20).
The host should recognize and use comma, tab and space as white space characters.

1.5 Units
All temperature values will be communicated in two byte hex values of qCx100 (.01 Cq). Resolution of
temperature values is .1 degree. All pressure values will be communicated in integer psi with no offset.

1.6 Commands
1.6.1

The following host Control messages are defined:

1.6.2

Read Chiller Status
This command (‘R’) will cause the Chiller Control to return a complete status string with the
following form:

Kodiak Recirculating Chiller Technical Manual

LYTRON COOLING SYSTEMS SERVICE POLICY
Lytron’s cooling systems are the product of over 40 years of thermal engineering and
manufacturing experience. We designed them to provide superior reliability, easy
maintenance, and worry-free operation. However, occasionally a system may need repair. To
ensure your process is back up and running quickly, Lytron has implemented the following
cooling system service policy.
Lytron's Standard Warranty
Lytron's warranty is set forth at the end of the cooling system manual sent with each product.
Diagnostic Consultation:
At no cost, Lytron will attempt to diagnose the problem over the phone. Our service department can
be reached by calling +1-781-933-7305 and following the menu. Service technicians are available 24
hours/7 days for consultation. Lytron strongly encourages customers to take advantage of this service
before returning a cooling system to Lytron for evaluation. Often a problem with a system can be fixed
quickly in-house or is an application problem. By working with Lytron’s service department to
troubleshoot a cooling system, you do not have the downtime and expense associated with returning
the system to our factory.
Phone diagnosis can be difficult and may actually be a trial and error process. Lytron will not assume
any liability for misdiagnosis when diagnosing over the phone.
Warranty and Non-warranty Returns:
To return a cooling system, a Lytron Return Material Authorization (RMA) number must be obtained
from Lytron’s service department, which can be reached by calling +1-781-933-7305 and following the
menu. Prior to calling, the system part number, serial number, and a detailed description of the
problem must be recorded, as this information is required to assign an RMA number. A Purchase
Order, (PO), is also required for the evaluation and repair charges if Lytron determines the system is
not defective as defined by the warranty (see below for more details). The RMA number should be
indicated on the outside packaging of the returned unit. Systems must be returned clean, dry, and
free from chemicals to Lytron’s factory, shipping costs prepaid. Lytron is not responsible for any
damage incurred in the return shipment.
Lytron ordinarily will evaluate the unit within 2 or 3 business days of receipt. Lytron will use
reasonable effort to repair the unit promptly, in most cases within one week of receiving all the
required parts.
If upon examination Lytron determines the system is not defective as defined by the warranty, an
evaluation fee of $375 to $595, depending upon the system type will be charged. The evaluation fee
will be charged regardless of disposition (i.e.: scrap).
In order to expedite the repair process for both warranty and non-warranty repair returns, a PO is
required with recommended limits that will be determined when calling for the RMA. The amount
suggested will cover the evaluation fee and most repair charges for non-warranty repairs. Lytron will
proceed with the repair unless the total charges (evaluation and repair) exceed the amount of the PO.
If this is the case, Lytron will provide a quote before proceeding with the repair. Repairs determined to
be covered under warranty will not have any charges posted against the PO.

Kodiak Recirculating Chiller Technical Manual

Debit memos should not be issued for warranty and non-warranty repairs unless the unit is returned
as a result of an out-of-box (new) failure.
Lytron will warranty the repair for one year from the repair date under the terms of our standard
warranty or for the balance of the original warranty, whichever is longer.
Return Shipments:
Lytron’s warranty covers payment for standard, ground return shipment of warranted repairs. The
incremental difference for expedited return shipments, if requested, are the responsibility of the
customer. After non-warranty repair, Lytron will ship the system back using the customer’s preferred
shipping method.
Field Service/Installation Charges
Where available, Lytron can arrange field service for cooling system installation or repair. Under no
circumstances does Lytron’s warranty cover on-site service. All on-site service must be arranged
through Lytron’s service department. The charges for this service are as follows:
$250 administrative fee
x
x
x

Plus the following:
$100/hr for on-site services provided*
Any related travel charges
Parts not covered under warranty.
*

The hourly labor rate may vary depending upon city. Contact Lytron’s service
department for current rates in effect at the time.

All requests for On-Site Services require a PO or credit card in the amount of $800 before services
will be scheduled.
When using Lytron-arranged, on-site service, Lytron warranties the replacement parts and repair
labor for 90 days from the repair date under the terms of our standard warranty or for the balance of
the original warranty, whichever is longer. If non-authorized labor repairs the system or installs
replacement parts, Lytron does not warranty the parts or work and this action potentially voids any
remaining warranty.
Lytron is expanding its worldwide service presence. Please contact the Service Department for the
latest areas where on site service is available.
Replacement Parts:
Replacement parts can be ordered using a credit card or purchase order. Parts being returned from
systems under warranty should be returned using a Lytron issued RMA number. If the parts are found
to be defective and the claim is within the warranty period, credit will be issued for the price of the
parts and one-way ground shipping charges. If the parts are not defective or indicate end user
damage, no credit will be issued. Lytron will not cover the incremental cost of air shipment of
replacement parts, regardless of warranty status.
In-stock parts normally will be shipped the next business day; non-stocked parts will be shipped as
quickly as reasonably possible.
This policy is subject to change. Please check with Lytron’s service department for the current policy.
