MAJOR
Constant
•
GENERAL
•
Omnizone TM 50BV indoor packaged units are very flexible
for a variety of applications.
These self-contained
units are
available as water-cooled or remote air-cooled air conditioning
units. The 50BV units are available with either constant volume (CV) or variable air volume (VAV) controls. In addition,
the 50BV unit is available as a water-cooled heat pump. Finally, Omnizone 50BV units are available in two cabinet styles.
Nominal 18 through 30-ton units are constructed in a singlepiece, unpainted
galvanized
cabinet. Nominal
30 through
60-ton units are available as modular units, and can be taken
apart for easier installation. Modular units are built using an unpainted, galvanized steel cabinet with steel framework, and can
be easily disassembled without breaking the refrigerant lines.
See Table 1 for a model number reference by application.
•
Each unit contains multiple scroll compressors
piped in
separate refrigerant circuits. Each water-cooled circuit includes
a coaxial (tube-in-tube) condenser, TXV (thermostatic expansion valve), individual evaporator coils, and all interconnecting
piping. Water-cooled
units are shipped fully charged with
refrigerant. Remote air-cooled units are shipped with a nitrogen
holding charge.
•
Each unit is equipped with one or two forward-curved
centrifugal blowers, to ensure quiet air delivery to the conditioned
space. Constant volume units operate at a single, adjustable fan
speed and provide zone temperature control using a standard
colrnnercial thermostat. For VAV applications, the unit is supplied with a variable frequency drive(s) (VFD) that automatically adjusts blower speed to maintain a constant, adjustable
duct static pressure. Compressors are automatically staged to
provide supply air temperature control (VAV applications) or
zone temperature control using a two-stage colmnercial thermostat (CV applications).
Volume
COMPONENTS
(CV) Units
MAIN CONTROL BOARD (MCB) -- The main
control
board for the 50BVC, E, Q, T, U, and V units provides both
controls and diagnostics including:
•
Use care in handling, rigging, and setting bulky equipment.
SYSTEM
•
•
•
•
•
Condensate Overflow Protection prevents unit operation in
the event that the drain pan clogs (optional
sensors
required).
Random Start provides a progralmnable
start with a range
of 30 to 60 seconds.
Anti-short Cycle Thner provides a 5-minute delay to prevent compressor short cycling.
Low Pressure Bypass Thner bypasses the low-pressure
switch for 90 seconds to avoid nuisance trips during cold
start-up.
High Pressure Switch Delay is a one-second delay that prevents nuisance trips at start-up.
Brownout/Surge/Power
Interruption
Protection
is a
20-second moving scale that works in coNunction with the
random start timer to delay unit start when a nuisance lockout would otherwise have occurred. This allows the water
pumps to restart and establish water flow.
Alarm Output contacts provide remote fault indication.
Test/Service Pin is a jumper that reduces all time delay
settings to 6 seconds during troubleshooting
or operation
verification.
Reset occurs after a 5-minute delay when a fault condition
occurs. When the timer expires, the unit will restart. If the
same condition occurs a second time, the unit will be locked
out.
Lockout Reset requires that the unit power be cycled at the
unit controller via either the thermostat or unit disconnect.
NOTE: The refrigerant circuits on dual compressor models
are completely independent. If either stage has a fault condition the remaining stage will continue to operate without
interruption. A freeze (optional sensor required) or condensate
overflow lockout will shut down both refrigerant circuits.
• LEDs are provided for diagnostic purposes.
Variable Air Volume (VAV) Units -- The 50BVJ,K,
W, and X units come equipped with a Carrier 6400 Comfort
Controller and a VFD. Refer to the 50BV, XJ Controls, Operation and Troubleshooting
manual for details.
NOTE: The VAV units utilize face split coils and should not
be operated below 50% of nominal airflow to prevent coil
freezing.

INSTALLATION
Omnizone TM 50BV units are intended for indoor installation only. Determine building alterations required to run piping,
wiring, and ductwork. Read all installation instructions before
installing the unit.
Step 1 E Complete
Pre-lnstallation
Checks
EXAMINE THE UNITExamine
the unit for shipping
damage. File a claim with the transit company if damage is
found. Check the shipment for completeness. Verify that the
nameplate electrical requirements
match the available power
supply.
UNIT STORAGE -- The 50BV units are designed and packaged for indoor storage and use only. If the equipment is not
needed for ilrnnediate installation upon its arrival at the job site,
it should be left in its shipping carton and stored in a clean, dry
area. Units must only be stored or moved in the normal upright
position, as indicated by the "UP" arrows on each carton, at all
times. DO NOT STACK UNITS.
MODULAR UNITS -- The 50BVT,U,V,W,X units are shipped
in multiple sections for easy lnovement and installation. The
separate modules will pass through a standard 36-in. steelframed door or service elevator. Circuit integrity is maintained
because none of the refrigerant piping requires disconnection.
Water piping connections are made with the use of heavy-duty
bronze-bodied unions so no field welding or brazing is required.
See Table 2 for the number of sections per unit.
For single piece units, use spreader bars and rigging straps if
lifting with a crane to avoid damage to the unit. Otherwise,
move with a fork truck using the shipping pallet.
Refer to Fig. 2-14 for unit dhnensions.
Refer to Tables 3A and 3B for physical data.
REMOVE PACKAGING
-- Remove all protective
plastic,
remove and discard unit top cover protector, filter cover,
controller display protector,
and water piping connection
packaging.
UNIT LOCATION--Locate
the unit in an indoor area
that allows easy removal of the filters, access panels, and
accessories. Make certain enough space is available for service
personnel to perform maintenance or repairs. Provide sufficient
room to make all water, duct, and electrical connections. If the
unit is located in a small mechanical equipment room, make
sure adequate space is available for air to return freely to the
unit. These units are not approved for outdoor installations and
must be installed inside the structure. Do not locate in areas
that are subject to freezing.
UNIT PLACEMENTEnsure that the floor is structurally
strong enough to support the weight of the equipment with
minimum deflection. A good, level floor is required for proper
unit operation and to ensure proper fit-up and aligmnent of all
bolt together and union coupled modules on modular units.

ACOUSTICAL
CONSIDERATIONS
-- Proper acoustical
considerations are a critical part of every system's design and
operation. Each system design and installation
should be
reviewed for its own unique requirements.
For job specific
requirements, contact an acoustical consultant for guidance and
recolmnendations.
6.
For VAV units only, connect the plenum robing, coiled
behind the VAV control panel, to the bulkhead fittings
located in the discharge of the supply fan. This connects
the high pressure supply to the high side of the duct high
static pressure switch.
In general, to reduce noise, consider the following:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
Locate mechanical
room and ducts away from noise
sensitive locations.
Whenever
possible, work with the
architect
to locate the equipment
rooms
around the
perimeters
of restrooms,
hallways,
fire escapes,
stair
wells, etc., to reduce noise transmission.
This allows not
only for isolation from radiated sound but also enables
the contractor
to route duct systems around sensitive
locations.
Construct the equipment room of concrete block or use a
double offset stud wall with interwoven
insulation. Seal
all penetrations.
Design the system for low total static pressure.
Use suitable vibration isolation pads or isolation springs
according to the design engineer's specifications.
A flexible canvas duct connector
is recommended
on
both the supply and return air sides of units to be
connected to system ductwork.
Use a minimum of 15 ft of return ductwork between the
last air terminal or diffuser and the unit.
Insulate supply and return ducts with 2-in., 3-1b density
insulation.
Round duct is recolmnended.
If rectangular
ductwork is
used, keep aspect ratios as small as possible (i.e., as close
to square as possible).
Avoid any direct line of sight from return air grilles
into the unit's return. If return air is to be ducted to an
equipment room, an elbow should be installed within the
equipment room.
Running a return air drop to near the floor of the room
will aid in sound attenuation.
Do not exceed the recolmnended
supply duct velocity of
2,000 fpm.
Do not exceed the recommended
return duct velocity of
1,000 fpm.
Use turning vanes on 90-degree elbows.
Place isolation springs under each corner and under each
compressor if utilized.
Remove all shipping blocks, if any, under blower housing
or damage to the fan may occur.
Step 3 -- Install Ductwork
The VAV units
must

When reattaching the filter/economizer

filter/economizer
section facing out and away from the
mare air conditioning section.
2. If the unit has 2 filter/economizer

remaining
filter/economizer
section
and mare
airconditioning section together, as in Step 1.
3. For units with 2 filter/economizer

A flexible canvas duct connector is recolmnended
on both
supply and return air sides of the units to be connected to the
system ductwork.
All metal ductwork should be adequately insulated to avoid
heat loss or gain and to prevent condensation from forming on
the duct walls. Uninsulated ductwork is not recommended,
as
the unit's performance will be adversely affected.
Do not connect discharge ducts directly to the blower
outlet(s). The factory filter should be left in place on a free
return system.
If the unit will be installed in a new installation, the duct
system should be designed in accordance with the System Design Manual, Part 2 and with ASHRAE (American Society of
Heating, Refrigeration and Air Conditioning Engineers) procedures for duct sizing. If the unit will be connected to an existing
duct system, check that the existing duct system has the capacity to handle the required airflow for the unit application at an

This unit has multiple independent refrigerant circuits with
separate condensers. The individual condensers are manifolded
together on the waterside to provide easy, single-point water
connections. In order to achieve proper head pressure control
when a water-regulating
valve is used, a temperature-actuated
valve is recolrnnended.
This allows any of the independent
refrigerant circuits to operate while still modulating condenser
water flow in response to loop water temperature.

All manual flow valves used in the system should be of the
ball valve design. Globe or gate valves must not be used due to
high pressure drops and poor throttling characteristics.
Do not exceed recolmnended
condenser fluid flow rates
shown in Tables 5A and 5B. Serious damage or erosion of the
heat exchanger tubes could occur. Piping systems should not
exceed 10 fps fluid velocities to ensure quiemess and tube wall
integrity. Refer to Tables 5A and 5B for condenser water pressure drop versus flow rate. Flow rates outside of the published
range should not be used.
Supply and return water piping must be at least as large as
the unit connections, and larger for long runs. Refer to the
System Design Manual, Part 3, and standard piping practice,
when sizing, planning, and routing water piping. See dimension drawings (Fig. 2-14) for water connection sizes and

If calculating the trap depth for the cooling coil, use the total
static pressure drop (coil plus any other components upstream
of it) plus 1 in. (P1 = negative static pressure + 1 m.), as shown
in Fig. 21.
Traps must store enough condensate to prevent losing the
drain seal at start-up. The "Mimmum 1/2PI" dimension ensures
that enough condensate is stored.

HOT WATER HEAT_G COIL (Optional) --A factory-installed
one or 2-row hot water heating coil is available as an option. The
coil is supplied with hot water from a boiler through separate pipmg from the condenser water loop. All controls for heating operation are field-supplied.
Piping should be in accordance
with accepted industry
standards and all components rated for the system pressure
expected. Pipe the coils so that they will drain, and provide a
dram and vent.
LEGEND
Flow Rate
Pressure Drop (ft wg)
Always connect the supply to the top of the coil, and the
return to the bottom. Refer to Fig. 2-14 for hot water supply
and return piping locations.
Water coils should not be subjected to entering air temperatures below 38 F to prevent coil freeze-up. If air temperatures
across the coil are going to be below this value, use a glycol or
brine solution. Use a solution with the lowest concentration
that will match the coldest air expected. Excess concentrations
will greatly reduce coil capacity.
The return air duct system should be carefully designed to
get adequate mixing of the return air and outdoor air streams to
prevent cold spots on the coil that could freeze.
A 2 or 3-way, field-supplied modulating control valve, or a
simple 2-position on-off valve may be used to control water
flow. Select the valve based on the control valve manufacturer's
recolmnendations for size and temperature rating. Select the
control valve CV based on pressure drop and flow rate through
the coil. This information is available from the VPA('Builder
software program or Tables 6A and 6B.
Pressure and temperature ports are recolmnended
in both
the supply and return lines for system flow balancing. These
openings should be 5 to 10 pipe diameters from the unit water
connections. For thorough mixing and temperature stabilization, wells m the water piping should extend at least 1/2 pipe
diameter into the pipe. Measuring the condenser waterside
pressure drop and refemng to Tables 5A and 5B can help to
properly set the water flow rate.
Improper fluid flow due to valvmg, piping, or improper
pump operation constitutes abuse that may result in voiding of
unit warranty. The manufacturer
will not be responsible for
damages or failures resulting from improper piping design or
piping material selection.

WATER ECONOMIZER
(Optional) -- The optional waterside
economizer (pre-coolmg coil) is factory-installed and piped internally, m series with the condenser water circuit (Fig. 21). A divertmg valve and factory controls are included with the option. Only
one set of field connections needs to be made for condenser water
and economizer water. In addition, when the unit is shipped with
the economizer option, the economizer dram must be connected
to a separate trap. Follow the same steps for the economizer dram
as described for the evaporator condensate dram. An Aquastat is
used to modulate water flow through the economizer. The controller is mounted to the low voltage control box. Electrical connections are factory installed and wired. The remote bulb is shipped
mtemal to the unit and requires field mounting. Care should be
taken not to dent the bulb or miscalibration may occur. The
Aquastat has a temperature range adjustment (-30 F to 100 F) and
is field set. See Fig. 2-14 for connection locations and sizes. See
Tables 7A and 7B for economizer waterside pressure drop data.
The waterside economizer
can also be ordered without
factory-installed
piping or controls. This offers additional
flexibility for specific applications. In this case, the coil is
factory mounted, but all supply and return piping and controls
are field supplied.

50BV units up to 30 tons, there will be 2 hot gas lines and 2 liquid lines to install between the unit and the condenser. Above
30 tons, 4 hot gas lines and 4 liquid lines will be installed between the unit and the 2 condensers. Refer to the System Design Manual, Part 3 for standard refrigerant piping techniques.
Also see the air-cooled condenser installation instructions for
additional guidance.

Verify that electrical requirements listed on the unit nameplate
match available power supply. The unit voltage must be within
the range shown in Tables 9A and 9B and phases must be
balanced within 2%. Contact the local power company for line
voltage corrections. Never operate a motor where a phase imbalance in supply voltage is greater than 2%.
Remote air-cooled 50BV units (only) are shipped with a dry
nitrogen holding charge. After refrigerant
connections
are
made, release nitrogen, evacuate, leak test, and charge the

SUPPLY AIR TEMPERATURE
SENSOR (SAT) -- The supply air temperature sensor (Fig. 29) is used to measure the
temperature of the air leaving the unit. The sensor should be
located m the supply air duct, about 1 ft from the unit discharge
connection (Fig. 30). On units with 2 fans, locate the sensor approximately 5 duct diameters downstream from "pair of pants"
duct connection, allowing for adequate mixing of supply air.
Mount the sensor as follows:
NOTE: Conductors and dram wire must be at least 20 AWG
(American Wire Gage), stranded, and tinned copper. Individual
conductors must be insulated with PVC, PVC/nylon, vinyl,
Teflon R_*,or polyethylene. An aluminum!polyester
100% foil
shield and an outer jacket of PVC, PVC/nylon, chrome vinyl,
or Teflon with a minimum operating temperature range of
-20 C to 60 C is required.
1. Remove the cover of the sensor junction
box.
2.
Drill a 7/16-m. hole at the selected location.
3.
Install the sensor through the hole and secure using 2
no. 8 screws (provided). Do not overtighten.
Connect the sensor to the control box. Use an 18 or
20 AWG, 2 conductoc twisted pair cable. This cable is
suitable for distances of up to 500 feet.
4.
The colrnnumcation
bus shields must be tied together at
each system element. If the colrnnumcation
bus is entirely
within one building, the resulting continuous shield must be
connected to ground at only one single point. If the colmnumcation bus cable exits from one building and enters another
building, the shields must be connected to the grounds at a
lightning suppressor m each building (one point only).

Connect the field wires to the supply air sensor using wire
nuts or closed end style crimp connectors. Do not cut the
sensor leads. Use the full length of lead supplied on the sensor.
In the control box, remove the jacket from the cable. Route
the sensor wires over to the right hand side of the field terminal
block (TB2). Strip the insulation back about 1/4-in. from each
conductor. Connect the two wires to terminals 101 and 102

Wait 24 house" before starting the compressol_"
wan_fing by the crankcase heatet_'.
AFTER
24 horns', continue with the procedures
to pelwfit
below.
CONFIRM THE INPUT POWER PHASE SEQUENCE
-The input power phase rotation sequence must be L1-L2-L3 =
ABC (or forward or clockwise) as indicated with a phase
rotation meter. Incorrect input phase rotation will cause the compressors to rotate in reverse, which results in no cooling capacity.
IMPORTANT:
On VAV units, fan rotation direction
can NOT be used for the phase sequence check; fan
rotation for VAV units with a variable speed drive is
independent of the unit input wiring sequence.
If the compressor is rotating in the wrong direction, it may:
emit increased noise; shut down due to internal overload
protection; have only a small decrease in suction pressure when
it starts; or have only a small increase in discharge pressure
3O
whenit starts.Also,no coolingwill beproduced
at the
evaporator.
If anyof theseconditions
occurs,
referto the
Service
sectionto correctthecompressor

See Tables 13-20 for fan performance data. Be sure that fans rotate in the proper direction.
COOLING -- Set the space thermostat to OFF position. Turn
on unit power. Set space thermostat to COOL and the fan to
AUTO. Adjust the thermostat temperature setting below room
temperature. Compressor 1 starts on closure of contactor (compressors 1 and 2 on 4-circuit units with 2-stage thermostat).
Adjust the thermostat to an even lower setting until the thermostat energizes Y2 (the second cooling stage). Compressor 2
starts on closure of contactor (compressors 3 and 4 on &circuit
units with 2-stage thermostat).
Adjust the thermostat temperature to a setting just below
room temperature. The second stage of cooling should turn off.
Set the thermostat temperature above room temperature.
compressors and the unit fan should now be off.
HEATING (Heat Pump Units Only) -- Follow the same sequence as for cooling (above), except set the space thermostat
to HEAT, and instead of adjusting the thermostat below room
temperature, adjust it above. Verify that the compressors turn
on and the unit runs in reverse cycle mode.
Set the thermostat below room temperature
that the compressors and fan turn off.

Contact closure at the 'G' terminal will provide power to
the supply fan contactor, energizing the supply fan. The supply
fan will be off during unoccupied schedule, depending upon
the features of the thermostat used. The 'O' terminal energizes
the reversing valve (heat pump units only). Typically 'YI' will
also be energized at this time for cooling operation. During the
second stage of cooling, 'Y2' will be initialized after a minimum mn time and after there is a differential from set point
plus a deadband or a proportional

scribes the various sequences that occur depending upon the
way an operation is triggered and which software control
points are involved.
SUPPLY FANThe supply fan can be activated
the following ways:
During the 5-minute delay, the cooling and heating routines
become disabled. This delay allows a compressor
that may
have just started to mn for its 5-minute minimum on time with
the supply fan on. For example, if the staging routine had just
started Compressor 3 at the time the OKFAN point changed to
OFF, the cooling routine would become disabled and compressors 1 and 2 would shut off right away. Compressor
three
would continue to mn for its mimmum on time of 5 minutes.
The fan continues running until all compressors meet the minimum on time and mn with a load, preventing them from shutting down due to a safety.

OKFAN will turn on followed by the points TRMCT for air

water flow and temperature
control. Approximately
20 to
30 seconds later, the supply fan (SF) point will turn ON and the
VFD output SPEED will increase. The SPEED point will
output a signal, determined by a PID (proportional integral derivative loop) calculation, based on the duct static pressure
(DSP) input and the supply static pressure
setpoint in
SETPT05.
COMRES triggers the compressor staging routine that controls the number of compressors energized. Units are equipped
with 2 or 4 compressors piped in separate refrigerant circuits,
and staged On!Off in a fbxed sequential manner (compressor
no. 1 through compressor no. 4). The compressor control routine uses a PID calculation to determine the percentage of cooling required, from 1 to 100%. Demand for the PID calculation
is determined from the supply air temperature and the supply
air setpoint (SETPT06).
Once the supply fan is running and the static pressure increases above the supply fan stares setpoint in SETPT01, the
supply fan status point (SFS) will indicate ON and the software
point SF_SFS will indicate TRUE.

WATER ECONOMIZER
COOL1NG -- The
unit
diverts
condenser inlet waterflow through an optional economizer coil
to precool evaporator entering airflow. If the entering water
temperature is colder than the setting on the aquastat, and the
return-air temperature is warmer than the setting on the returnair thermostat, the three-way diverting valve will direct water
to the economizer coil.
If there is no RAS connected to the EWT input, the space
control point will display a default value of 75 F. This value is
above the default occupied cooling set point and below the
unoccupied cooling set point. If this condition exists, supply air
reset from a sensor and unoccupied
unit operation will not
occur.
If the unit is configured to use an RAS sensor for the Space
Control Point or if linkage is active and the space has unoccupied demand, the software point OKFAN will turn on followed
by the software points TRMCT for air terminal control and
PUMP and TOWER to request condenser water flow and temperature control. Approxhnately
20 to 30 seconds later the SF
point will turn ON and then the VFD output SPEED will increase. If unoccupied demand is the reason the fan is on, a control force will appear next to the OKFAN point. Otherwise,
there should not be a force on that point.
Economizer water flow is in series with the condensers,
allowing compressor operation while the economizer is
operating.
NOTE: The return-air thermostat (RAT) is separate from the
RAS sensor.
COOLING RESET -- The 5 kiloohm temperature sensor will
be used as the space control point. If this variable goes below
the occupied high set point in the HEAT/COOL MODE AND
RESET set point (SETPT03), then for each degree that the
space control point is below the set point value, the supply air
set point will be reset by the value configured in the custom
configuration RESET RATIO.
If the fan is running due to unoccupied heating or cooling
demand, either the space temperature (if installed), return-air
temperature, or average linkage temperature must rise or drop
to within half way between the occupied and unoccupied set
points in order for the fan to turn back off.
Diagnostic
Features (CV Only) E The mare control board (MCB) in the constant volume units has 2 LEDs that
provide diagnostic information. Refer to the Troubleshooting
section for a detailed description of the LED codes.
Enabled by Switching to Local Mode -- When the switch is
placed in the Local mode the ROCC point will indicate enable.
IfROCC is ENABLED a software routine will override the occupancy schedule so that TIMECLOCK
will also turn on.
When ROCC is turned off the TIMECLOCK
point will turn
off within 60 seconds.

Also, check that the fan is rotating in the proper direction.
NOTE: When the compressor is rotating in the wrong direction, the unit makes an elevated level of noise and does not
provide cooling.
Condensate Drains
E Clean the drain line and unit
drain pan at the start of each cooling season. Check flow by
pouring water into the drain.
Fan Motor Replacement
E If required, replace the
fan motor with an equal or better type and efficiency motor
with equal horsepower. The motor must be rated for a VFD or
inverter application. Do not change the horsepower
unless
there is a system design requirement change and VFD size
analysis.
CHECK/CHANGE
VFD OUTPUT CURRENT
LIMIT -The VFD provides additional fan motor protection by limiting
the output current to a progralraned value. This value has been
factory set according to the factory-installed
motor and VFD
sizing options.
Water-Cooled Condensers
_ Water-cooled condensers may require cleaning of the scale (water deposits) due to
improperly
maintained
closed-loop
water systems. Sludge
build-up may need to be cleaned in an open tower system due
to inducted contaminants.
Local water conditions may cause excessive fouling or pitting of robes. Condenser tubes should be cleaned at least once a
year, or more often if the water is contaminated.
Proper water treatment can minimize robe fouling and
pitting. If such conditions are anticipated, water treatment
analysis is recolranended.
Refer to the System Design Manual,
Part 5, for general water conditioning information.
If the VFD and/or motor is replaced, the VFD setup mode
parameter "tHrl" should be reprogralraned
to the following
calculated values for optimum motor protection and operating
range:
For VFD size about equal to motor:
tHrl = 100*motor

Observe and follow acid manufacturer's instructions.
MAINTENANCE
Cleaning Unit Exterior-
Unit exterior panels should
be wiped down using a damp soft cloth or sponge with a mixrare of warm water and a mild detergent.
Isolate the supply and return water connections when removing piping to the condenser.
Clean condensers with an inhibited hydrochloric acid solution. The acid can stain hands and clothing, attack concrete,
and, without inhibitor, can attack steel. Cover surroundings to
guard against splashing. Vapors from vent pipe are not harmful,
but take care to prevent liquid from being carried over by the
gases.
Warm solution acts faster, but cold solution is .just as effective if applied for a longer period.
Coil Cleaning
-- Hot water, steam, and direct expansion
coils must be cleaned at least once a year to maintain peak performance. Dirty coils can contribute to decreased heating or
cooling capacity and efficiency, increased operating costs, and
compressor
problems
on direct expansion
systems. Dirt,
grease, and other oils can also reduce the wettability of the coil
surfaces, which can result in moisture blow-off from cooling
coils and resulting water leakage problems. If the grime on the
surface of the coils becomes wet, which COlmnonly occurs with

After 1 to 3 minutes of operation, check the belt tension.
Also check tension frequently during the first 24 hours of operation and adjust if necessary. Periodically check belt tension
throughout the mn-m period, which is normally the initial
72 hours of operation.
ALIGNMENT
-- Make sure that fan shafts and motor shafts
are parallel and level. The most cognnon causes of misalignment are nonparallel shafts and improperly located sheaves.
Where shafts are not parallel, belts on one side are drawn tighter and pull more than their share of the load. As a result, these
belts wear out faster, requiring the entire set to be replaced before it has given maximum service. If misaligmnent
is in the
sheave, belts enter and leave the grooves at an angle, causing
excessive belt and sheave wear.

1. To check the location of the fixed sheaves on the shafts,
use a straightedge or a piece of string. If the sheaves are
properly aligned, the string will touch them at the points

half revolution to determine whether the sheave is wobbly or the drive shaft is bent. Correct any misaligmnent.
2. With sheaves aligned, tighten cap screws evenly and
progressively.
NOTE: There should be a 1/,-m. to 1/4-in. gap between
the mating part hub and the bushing flange. If the gap is
closed, the bushing is probably the wrong size.
3. With taper-lock bushed hubs, be sure the bushing bolts
