CONDENSATE DRAIN

All units r equire cer tain clearances for pr oper operation and service. Refer to Figure 6 for the clearances required for combustion, construction, servicing and proper unit operation.

WARNING:Do not permit overhang in g s tructures or shrubs to

obstruct the conden ser air discharge outlet.

DUCT WORK

These units are adaptable to downflow use as well as rear supply and return air duct openings. To convert to downflow, use the fol lowing steps:

1. Remove the duc t covers found in the bottom return and supply air duct openings. There are f our (4) screws s ecuring each duct cover (save these screws to use later).

2. Install the duct covers, removed in step one, to the rear supply and return air duct openings. Secure with the four (4) screws used in step one .

3. Seal the duct covers with silicone caulking.

Downflow units must have an L-shaped supply duct without any outlets or registers located directly below the supply outlet of the unit.

Duct work should be designed and sized according to the methods of the Air Conditioning Contractors of America (ACCA), as set forth in their Manual D.

A condensate tr ap is requi red to be installe d in the co ndensate drain. The plumbing must conform to local codes. Use a sealing compound on male pipe threads. Install the condensate drain

SERVICE ACCESS

Access to all serviceab le compon ents is pro vided by th e fol lowing remov able panels:

• Blower service access

• Electrical/filter access

• Compressor service ac ce ss

Refer to Figure 6 for location of these access panels and minimum clearance.

THERMOSTAT

The room thermostat should be located on an inside wall approximately 56" above the floor where it will not be subject to drafts, sun exposure or heat from electrical fixtures or appliances. Follow manufacturer’s instructions enclosed with the thermostat for general installation procedure. Four, five or six color coded insulated wi res (minimum #18 A WG) shoul d be used to connect thermosta t to uni t. See Figure 3.

POWER AND CONTR OL WIRING

A closed return duct system shall be used. This shall not preclude use of economizers or ventilation air intake. Flexible joints may be used in the supply and return duct work to minimize the transmission of noise.

CAUT I O N : When fastening duct work to the side duct flanges on

the unit, insert the screws through the duct flanges only . DO NOT insert the screws through the casing. Outdoor duct work must be insula ted an d w aterproof ed.

NOTE: Be su re to note supply and return open in gs.

Refer to Figure 6 for information concerning rear and bottom supply and return air duct openings.

FILTERS

Single phase units are shipped without a filter and is the responsibility of the installer to secure a filter

or install a Filter/Frame Kit

A filter rack and a filters are stan dard on three phase units. Filters must always be used and must be kept clean. When

filters become dirt laden, insufficient air will be delivered by the blower, decreasing your units efficiency and increasing operating costs and wear-and-tear on the uni t an d co ntrols.

(1FF0114).

in the return air ductwork

Field wiring to the unit must conform to pro visions of the current N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances. The unit must be electrically grounded in accordance with local codes or, in their absence, with the N.E.C./C.E.C. Voltage tolerances which must be maintained at the compressor terminals during starting a nd running cond itions are indicated on the unit Rating Plate and Table 1.

The wiring entering the cabinet must be provided with mechanical strain relief.

A fused or HACR breaker disconnect switch should be field provided for the unit. If any of the wire supplied with the unit must be replaced, replacement wire must be of the type shown on the wiring diagram.

Electri cal line must be sized proper ly to carr y the load . Each unit must be wired with a separate branch circuit fed directly from the meter panel and properly fused.

Refer to Figure 2 for typical field wiring and to the appropriate unit wiring diagram for control circuit and power wiring information.

COMPRESSORS

Units are ship ped with comp ressor mounting s facto ry-adjusted and ready for operation.

Heating

The following sequences of operation are based on using a standard single -stage cooling th ermosta t .

WITH POWER TO UNIT AND THERMOSTAT IN COOLING MODE.

1. If the fan switch on the thermostat is in the "ON" position, the 24 volts at "G" will energize the "K1" relay on the fan control boar d, cl ose t he "K1 " re lay contacts, an d ener gize the indoor blower motor. If the fan switch is in the "AUTO" position, the b lower w ill operat e only when th ere is a call f or cooling by th e th ermosta t.

2. On a call for cooling, the thermostat will send 24 volts to "Y" on the fan control board. The 24 volt signal will energize contactor "M1", and power will be supplied to the compressor and outdoor fan motor. If the fan switch on the thermostat is on the "AUT O" position, the thermostat will also send a 24 volt signal to "G" on the fan control board and the indoor blower will operate as indicated in step 1.

3. When the deman d for cooling has been sat is fi ed , th e "M 1" contactor will be de-energized when the 24 volt "Y" signal is removed. If the fan switch on the thermostat is energized when the 24 volt "Y" signal is removed. If the fan switch on the thermostat is in t he "ON" positi on, the in door blo wer will continue to r un . If the fan switch is in the "AUTO" position, the 24 volt "G" signal will be removed, and after a 60 second delay, t he "K1" r elay will o pen and de -energ ize the indo or blower motor.

WITH POWER TO UNIT AND THERMOSTAT IN HEATING MODE.

1. If the fan switch on the thermostat is in the "ON" position, the 24 volts at "G " will energiz e the "K1" re lay co ntacts, a nd energize the indoor blower motor. If the fan switch on the thermostat is in the "AUTO" position, the blower will operate only when there is a cal l for heating by the thermostat.

2. On a call for heat ing, the ther mostat w ill send 24 volts to "W1" on the fan control board. The 24 volts signal will energize rel ay "K2" on the fan control board, and the first stage of electric heat will be energized.

3. When the heating demand is satisfied, the electric heat will be de-energized when the 24 volt "W1" and "W2" signals are removed. If the fan switch on the thermostat is in the "ON" positi on , th e in door blower w i ll co ntinu e t o run. If the fan s witch is in the "A UT O" position, th e "K1" rela y will op en and de-energize the indoor blower motor after the appropriate time delay.
