Locations and Recommendations

This unit was designed for multiple applications: rooftop, out-

door ground level. For proper installation, the following recom-

mendations must be considered:

Installation of the unit should conform to local building codes or,

in the absence of local codes, to the National Electrical Code.

Canadian installations must conform to CSA and local codes

Select a location that will permit unobstructed airflow into the

outdoor coil and away from the fan discharge. The discharge air

from the outdoor fan must be unrestricted for a minimum of three

(3) feet above the unit. Any reduction of the unit clearances

recommended may result in condenser coil starvation or the

recirculation of warm condenser air. Actual clearances which are

inadequate should be reviewed with a local sales representative.

If the unit is located under an overhang, provisions must be made

to deflect the warm discharge air from under the overhang. See

Figures 1, 2 and 3. The unit must also be situated to permit easy

and unrestricted access for service.

Install internal accessories to the unit at the shop if practical.

Access and service clearances for the unit must be given careful

consideration when locating the duct entrance openings.

Figure 1 provides unit dimensions.

All fabricated outdoor ducts should be as short as possible.

Be sure the openings in the structure are large enough to

accommodate the ducts and the insulation surrounding them.

See Figure 1.

For outdoor, ground level applications the unit must be mounted

on a solid, level foundation that is not adjoined to the structure

because sound and vibration may be transmitted to the struc-

ture.

Field supplied mounting pads should be placed beneath the unit

to prevent transmission of vibration to the occupied structure.

Select a location that will minimize the length of the supply and

return ducts.

Position the unit so roof-run-offwater does not pour directly onto

the unit.

Select a location where external water drainage cannot collect

around the unit.

CAUTION MUST ALWAYS BE TAKEN TO AVOID PERSONAL

INJURIES AND/OR DAMAGE TO THE EQUIPMENT.

Elevation minimums must be observed for drain line "trap" and

ventilation to the under side of the unit.

All duct work inside the structure should be adequately insu-

lated.

All duct work outside of the structure must be insulated and

weatherproofed in accordance with local codes. If supplementary

heat is added, the duct connectors should be of a flame retardant

material.

Give consideration to shade, appearance, and noise.

The following warning complies with State of California law, Proposition 65.

Electrical Wiring

WARNING :TO PREVENT INJURY OR DEATH

DUE TO ELECTRICAL SHOCK OR CONTACT WITH MOVING

PARTS. LOCK UNIT DISCONNECT SWITCH IN OPEN

POSITION BEFORE SERVICING UNIT.

Electrical Connections

Electrical wiring and grounding must be installed in accordance

with local codes or, in the absence of local codes, with the National

Electrical Code ANSI!NFPA 70, Latest Revision.

Disconnect Switch

Provide an approved weather-proof disconnect either on the side

of the unit or within close proximity and within sight of the

unit.

Over Current Protection

The branch circuit feeding the unit must be protected as shown

on the unit rating plate.

Power Wiring

The power supply lines must be run in weathertight conduit to

the disconnect and into the bottom of the unit control box.

Provide strain relief for all conduit with suitable connectors.

Provide flexible conduit supports whenever vibration transmis-

sion may cause a noise problem within the building structure.

Ensure all connections are made tight. See Figures 5 and 6:

Typical Field Wiring Diagrams.

NOTES:

1. For branch circuit wiring (main power supply to the unit

disconnect), wire size for the length of run should be

determined using the circuit ampacity found on the unit

nameplate and the N.E.C.

2. For more than 3 conductors in a raceway or cable, see the

N.E.C. for derating the ampacity of each conductor.

3. Wire size is based on 75 degrees C rated wire insulation.

Grounding

The unit must be electrically grounded in accordance

with local codes or the National Electrical Code.

Accessories

All electrical accessories must be installed and wired according

to the instructions packaged with the accessory.

Control Wiring (Class II)

Low voltage control wiring should not be run in the same conduit

with the power wiring unless Class I wire of the proper voltage

rating is used. Route the thermostat cable or equivalent single

leads of No. 18 AWG colored wire from the thermostat subbase

terminals through the rubber grommet on the unit. See Figure

1 for the control entry location. Make connections as shown on

the unit wiring diagram and in Figures 5 and 6.

Do not short thermostat wires since this will damage the control

transformer.

Electrical Wiring

Recommended wire sizes and lengths for installing the unit

thermostat are provided in Table 1: Thermostat Wire Size

and Maximum Length. The total resistance of these low

voltage wires must not exceed one (1) ohm. Any resistance in

excess of one (1) ohm may cause the control to malfunction

because of the excessive voltage drop.

IMPORTANT: Upon completion of wiring check all elec-

trical connections, including factory wiring within the

unit.

Make sure all connections are tight. Replace and secure all

electrical box covers and access doors before leaving the unit or

turning on the power to the unit.

After all electrical wiring is complete, set the thermostat system

switch on the OFF position so that the compressor will not run

and then apply power by closing the system main disconnect

switch. This will activate the compressor sump heat. Do not

change the Thermostat System Switch until power has been

applied long enough to evaporate any liquid HCFC-22 in the

compressor. It is recommended that the sump heat be energized

for a minimum of eight (8) hours prior to starting the unit.

Sequence of Operation

The unit's operation is controlled by the remote room thermostat.

Once the thermostat is placed in the COOL position, the unit's

operation is automatic. A fan switch on the thermostat also

provides for continuous operation of the evaporator fan if desired.

This is the ON position. With the fan switch in the AUTO

position, the fan will only operate with the cooling cycle. Continu-

ous fan mode during cooling operation may not be appropriate in

humid climates. If the indoor air exceeds 60% relative humidity

or simply feels uncomfortably humid, it is recommended that the

fan only be used in the AUTO mode.

Cooling

On a call for cooling, the indoor fan "G" and the compressor

circuit'S' are energized. The indoor fan circuit"G" energizes the

the fan relay coil this closes the fan relay contacts (FDR-1) and

the indoor fan motor(IDFM) starts. The compressor circuit '5_"

energizes the (MS) contactor coil this powers the compressor

(CPR) and the outdoor fan motor (ODFM). When the thermo-

stat determines that further cooling is not required, the contactors

are de-energized.

Short Duration Shut Down

To shut down the unit for a brief period of time, turn the

thermostat system switch to OFF and place the fan switch in the

AUTO position.

Heating

On a call for heat, the thermostat '3Y" is energized, which

connects to unit'%Y", which energizes the "AH" heater contactor

coil. The"AH" contactor closes powering the heater, provided all

element limits are closed.

Note: The indoor thermostat must be configured for electric

heat to provide a"G" signal to energize the indoor fan relay (FDR-

1) during the heating mode. The heater control circuit will not be

energized unless the indoor fan relay (FDR-2) is energized.

ICM FAN MOTOR ADJUSTMENTS (TCH048, 060F ONLY)

If the airflow needs to be increased or decreased, see the Airflow

Table in the Service Facts. Information on changing the speed of

the blower motor is in the Blower Performance Table.

Blower speed changes are made on the ICM Fan Control mounted

in the control box. The ICM Fan Control controls the variable

speed motor.

There is a bank of 8 dip switches (See Figure 7), located at the

upper left side of the board. The dip switches work in pairs to

match the cooling/heat airflow (CFM/TON), Fan off-delay op-

tions, and electric heat airflow adjustment. The switches appear

as shown in Figure 7.

Start-Up

Pre-Start Quick Check List

•Is the unit properly and securely located and level with the

proper clearance?

•Is the ductwork correctly sized, run, taped, insulated and

weatherproofed with the proper unit arrangement?

•Is the condensate line properly sized, run, trapped, and

pitched? Does it drain freely?

•Is the filter of the correct size and number? Are the supply

and return registers unobstructed?

•Is the wiring properly sized and run according to the Unit

Wiring Diagram, Figures 5 and 6?

•Is the power supply correct for the unit's requirements?

•Are all wiring connections, including those in the unit

itself, tight?

•Is the thermostat well located, level, correctly wired, and

accurately adjusted?

•Do the outdoor fan and the indoor fan turn free without

rubbing? Are both fans tight on their shafts?

•Has the indoor blower speed tap been determined andthe

proper speed set? See the Unit Wiring Diagram,Figures 5

and 6.

•Has all work been done in accordance to the applicable

local and national codes?

•Are all cover and access panels in place to prevent air loss

and to protect against safety hazards?

•Have all tools and debris around, on top of, and under the

unit been removed?

Starting the Unit In the Cooling Mode

IMPORTANT: Before starting the system in the cooling

cycle, turn the thermostat switch to "OFF" and close the

unit disconnect switch. This procedure energizes the

compressor crankcase heat (if equipped) thereby vapor-

izing any liquid HICFC-22 in the crankcase. This is a

precaution against foaming at start-up which could

damage the compressor. Allow the heat to operate for a

minimum of eight (8) hours.

The TCH048-060F units do not have sump heat as shipped.

NOTE: The crankcase heater is a field installed option on

some models.

NOTE: See the section on "Sequence of Operation" for a

description of the cooling operating sequence.

•To start the unit in the cooling mode, set the thermostat

system switch to COOL.

Move the thermostat COOL indicator to a setting below

Page 8

Start-Up Start-Up

room temperature. The outdoor fan motor, compressor, and

evaporator fan motor will operate automatically.

Operating Pressures

After the unit has operated in the cooling mode for a short time,

install pressure gauges on the gauge ports of the discharge and

suction line valves. Check the suction and discharge pressures

and compare them to the normal operating pressures provided in

the unit's SERVICE FACTS.

Starting the Unit in the Heating Mode

NOTE: See the section on "Sequence of Operation" for a descrip-

tion of the heating operating sequence.

•Check to make sure that all grilles and registers are

open and all unit access doors are closed before start-up.

Voltage

With the compressor operating, check the line voltage at the unit.

The voltage should be within the range shown on the unit

nameplate. If low voltage is encountered, check the size and

length of the supply line from the main disconnect to the unit.

The line may be undersized for the length of the run.

Cooling Shut Down

• Place the system selector switch in the OFF position or reset

the thermostat at a setting above the room temperature.

•To start the unit in the heating mode, set the thermo-stat

system switch to HEAT. Move the thermostat

HEAT indicator to a setting above room temperature

and place the fan switch in the AUTO or ON positions.

The indoor fan motor will operate automatically.

•The thermostat must provide a "G" signal for fan operation.

If using an auto changeover thermostat, see Figures 5 and 6

for the appropriate connections.

Heating Shut-Down

• Do not de-energize the main power disconnect except when

the unit is to be serviced. Power is required to keep the

compressor crankcase heat (if equipped) energized and boil

off refrigerant in the compressor.

•Place the system selector switch to the OFF position or place

the heating selector lever at a setting below the room

temperature.

Maintenance

Routine Maintenance by Owner

You can do some of the periodic maintenance functions for your TCH unit

yourself. These functions include replacing the disposable or cleaning the

permanent air filters, cleaning the unit's cabinet, cleaning the condenser coil,

and conducting a general inspection of the unit on a regular basis.

WARNING: TO PREVENT INJURY OR DEATH

DUE TO ELECTRICAL SHOCK OR CONTACT WITH MOVING

PARTS. LOCK UNIT DISCONNECT SWITCH IN OPEN

POSITION BEFORE SERVICING UNIT.

Air Filters

It is very important to keep the central duct system air filters clean. Be sure

to inspect them at least once each month when the system is in constant

operation. In new construction, check the filters every week for the first

four (4) weeks.

•If you have disposable-type filters, replace them with new filters of

the same type and size. Do not try to clean disposable filters.

•Clean permanent-type filters by washing them with a mild detergent

and water. Make sure that the filters are thoroughly dry before re-

installing them in the unit.

•Replace permanent filters annually if washing fails to clean them or

ifthey show signs of deterioration. Use the same type and size as was

originally installed.

Outdoor Coil

Unfiltered air circulated through the unit's outdoor coil can cause the

coil's surface to become clogged with dust, dirt, etc. To clean the coil,

stroke the coil surface with a soft-bristled brush vertically, that is, in the

direction of the fins.

•Be sure to keep all vegetation away from the outdoor coil area.

Maintenance Performed by Serviceman

To keep your unit operating as designed, the manufacturer recommends

that a qualified serviceman check over the entire system at least once each

year as well as any other time that you feel that one is needed. Your

serviceman should examine and inspect:

•filters (for cleaning or replacement)

•motors and drive system components

•condenser coils (for cleaning)

•safety controls (for mechanical cleaning)

•electrical components and wiring (for possible replacement

and/or connection tightness)

•condensate drain (for cleaning)

In addition, your serviceman should inspect:

•unit duct connections to see that they are physically sound and sealed

to the unit casing

•unit mounting support to see that it is sound

•unit to see that there is no obvious unit deterioration.
