ntt:: Perform a final unit inspection to be sure
that factory tubing has not shifted during
shipment. Adjust tubing if necessary so
tubes do not rub against each other when
the unit runs. Also be sure that wiring
connections are tight and properly secured.
☐
Does the unit run and operate as described in the
Sequence of Operation section 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 determine 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

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.
FFiilltteerrss
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. D

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).

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.

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)
H

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.

Fault Detection
A fault condition is indicated by the flashing light on
the defrost control board located inside the heat pump
control box.
In normal operation, the defrost control light will flash
once each second. If the light is flashing more than
once per second or not at all, refer to the Demand
Defrost Control Checkout table.
