Final Installation Checklist


Does the unit run and operate as described in the section on
Sequence of Operation, page 26, in response to the room
thermostat?

Are the condenser fan and indoor blower operating correctly
with proper rotation and without undue noise?

Is the compressor operating correctly and has the system
been checked with a charging chart?

Has the voltage and running current been checked to deter
mine if it is within limits?

Has the thermostat been checked for calibration and the air
discharge grills adjusted to balance the system?

Has the ductwork been checked for air leaks and
condensation?

Has the furnace manifold pressure been checked and
adjusted if necessary?

Has the heating air temperature rise been checked?

Has the unit been checked for tubing and sheet metal
rattles? Are there any other unusual noises to be checked?

Are all covers and panels in place and properly fastened?

Has the owner been instructed on the proper operation and
maintenance of the unit? Be sure to leave this manual with
the owner.

Maintenance

Owner Maintenance

Some of the periodic maintenance functions of the unit can be
performed by the owner; this includes replacing the disposable
or cleaning the permanent air filters, cleaning the unit cabinet,
cleaning the condenser coil, and conducting a general unit
inspection on a regular basis.
Filters
When the system is in constant operation, inspect the filters
at least once each month.
If the unit has disposable-type filters, replace them with new
filters of the same type and size. Do not attempt to clean
disposable filters.
Permanent-type filters can be cleaned by washing them with a
mild detergent and water. Make sure that the filters are thoroughly
dry before reinstalling them in the unit (or duct system).
NOTE: It may be necessary to replace permanent filters
annually if washing fails to clean the filter or if the filter shows
signs of deterioration. Be sure to use the same type and
size as was originally installed.
Condenser Coil
Be sure to keep all vegetation and debris away from the con-
denser coil area.

Service Maintenance

Cooling Season

To keep the unit operating safely and efficiently, the manufacturer
recommends that a qualified service technician check the entire
system at least once each year or sooner if needed. The service
technician should examine these areas of the unit:
filters (for cleaning or replacement)
●
motors and drive system components
●
economizer gaskets (for possible replacement)
●
safety controls (for mechanical cleaning)
●
electrical components and wiring (for possible replacement
●
and connection tightness)
condensate drain (for proper sealing and cleaning)
●
unit duct connections (to see that they are physically sound
●
and sealed to the unit casing)
unit mounting support (for structural integrity)
●
the unit (for obvious unit deterioration)
●

Heating Season

Complete the following unit inspections and service routines at
the beginning of each heating season.
Visually inspect the unit to ensure that the airflow required
●
for combustion and condenser coil is not obstructed from the
unit.
Inspect the control panel wiring to verify that all electrical
●
connections are tight and that the wire insulation is intact.

Indoor Fan Motor Speed Tap Setting

The 208/230 and 460 Volt units are factory set to high speed
with one exception. The 4WC*3030 is factory set to low
speed.
208/230 Volt Motor Tap Settings (Figure 25, page 28)
High speed setting: On the IGN board:
1. Connect the "RD" wire to the "PARK" terminal.
2. Connect the (IDM) PR wire to the "BLOWER LOAD" termi-
nal.
Low speed setting: On the IGN board:
1. Connect the "RD" wire to the "BLOWER LOAD" terminal.
2. Connect the (IDM) PR wire to the "PARK" terminal.
460 Volt Motor Tap Settings (Figure 26, page 28)
High speed setting (460V):
1. At the "FTBA", connect the "PR" wire from the IGN board to
the "HI" (B) terminal.
2. Connect the "PR" wire from the "HI" (B) terminal on the
"FTBA" to the "H" terminal on the IDM.
3. Connect the Orange wire on the IDM to the "P" terminal on
thE IDM.
Low speed setting (460V):
1. At the "FTBA", connect the "PR" wire from the IGN board to
the "LOW" (D) terminal.
2. Connect the "PR" wire from the "HI" (B) terminal on the
"FTBA" to the "P" terminal on the IDM.
3. Connect the Orange wire on the IDM to the "H" terminal on
the IDM.
