CONDENSATE DRAIN
A condensate trap must be installed in the condensate drain. The
plumbing must conform to local codes.
Use Teflon tape or pipe thread compound if needed.
CAUTION
!
Hand tighten only.
SERVICE ACCESS
Access to all serviceable components is provided at the following loca-
tions:
• Coil guards
• Unit top panel
• Corner posts
• Blower access panel
• Control access panel
• Indoor coil access panel
• Compressor access panel
Refer to Figure 3 for location of these access locations and minimum
clearances in Table 4.
CAUTION
!
This system uses R-410A refrigerant which operates at higher pres-
sures than R-22. No other refrigerant may be used in this system.
Gage sets, hoses, refrigerant containers and recovery systems must
be designed to handle R-410A. If you are unsure, consult the equip-
ment manufacturer. Failure to use R-410A compatible servicing
equipment may result in property damage or injury.
WARNING
!
Wear safety glasses and gloves when handling refrigerants. Failure
to follow this warning can cause serious personal injury.
Refer to
for the R-410A Quick Reference Guide.
THERMOSTAT
The room thermostat should be located on an inside wall approximately
60" above the floor where it will not be subject to drafts, sun exposure
or heat from electrical fixtures or appliances. Sealant should be used
behind thermostat to prevent air infiltration. Follow manufacturer's
instructions enclosed with the thermostat for general installation proce-
dure. PCE6 model units all contain a multiple stage compressor, there-
fore a multi-stage thermostat must be used. Color coded insulated
wires (minimum #18 AWG) should be used to connect thermostat to
unit. See Figure 6.
If a field supplied electric heat kit is installed, this unit requires the use
of a 1 heat / 2 cool (1H/2C) thermostat for proper operation. Do not use
power stealing thermostats.
POWER AND CONTROL WIRING
Field wiring to the unit must conform to provisions 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 and running
conditions are indicated on the unit Rating Plate and Table 1.
The wiring entering the cabinet must be provided with mechanical
strain relief.
A fused 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.
Electrical service must be sized properly to carry the load. Each unit
must be wired with a separate branch circuit fed directly from the main
distribution panel and properly fused.
Refer to Figures 6-8 for typical field wiring and to the appropriate unit
wiring diagram for control circuit and wiring information.
Unit comes wired for 460 volt power.
