SECTION VIII: INSTRUCTING THE OWNER
Assist the owner with registering the unit warranty using the warranty
card included with the unit, or preferably online at
www.upgproductregistration.com. It is strongly recommended to com-
plete a startup sheet showing the critical readings of the unit at the time
of commissioning, which can be uploaded as part of the online registra-
tion process.
When applicable, instruct the owner that the compressor is equipped
with a crankcase heater to prevent the migration of refrigerant to the
compressor during the OFF cycle. The heater is energized when the
ambient temperature is below 55°F for 30 seconds continually and the
compressor has been off for 31 minutes. The heater will cycle ON for 10
minutes and OFF for 10 minutes, until the outdoor ambient is above
55°F for 30 seconds continually or an active demand for compressor
operation occurs. If the unit power supply is disconnected for long peri-
ods of time, do not attempt to start the unit until power has been applied
for a minimum of 2 hours. This will allow sufficient time for all liquid
refrigerant to be driven out of the compressor.
The installer should also instruct the owner on proper operation and
maintenance of all other system components.
OUTDOOR FAN OPERATION
The outdoor fan motor varies the outdoor fan RPM based on algorithms
within the control board software. This means that the fan motor could
change speed as required at any moment depending on conditions and
compressor stage. Do not be alarmed as this is normal operation. If the
conditions are on a break over point the motor could speed up and slow
down until a more constant condition is met. Under typical operation the
motor will speed up the warmer it is outside and slow down the cooler it
is outside to maintain highest efficiency and operating pressures as
needed. Charging of the equipment with the variable outdoor fan motor
is already accounted for in the charging charts for the equipment.
Should an outdoor fan motor failure ever occur requiring replacement,
the outdoor fan motor must be replaced with the original OEM part num-
ber through Source 1. Refer to unit repair parts list to find the appropri-
ate replacement part number.

MAINTENANCE
1. Dirt should not be allowed to accumulate on the outdoor coil or other
parts in the air circuit. Clean as often as necessary to keep the unit
clean. Use a brush, vacuum cleaner attachment, or other suitable
means.
2. The outdoor fan motor bearings are permanently lubricated and do
not require periodic oiling.
3. If the coil needs to be cleaned, it should be washed with water or a
PH neutral detergent. Allow solution to remain on coil for several
minutes before rinsing with clean water. Solution should not be per-
mitted to come in contact with painted surfaces.
4. Refer to the furnace or air handler instructions for filter and blower
motor maintenance.
5. The indoor coil and drain pan should be inspected and cleaned reg-
ularly to prevent odors and assure proper drainage.
CAUTION
!
It is unlawful to knowingly vent, release or discharge refrigerant into
the open air during repair, service, maintenance or the final disposal
of this unit.
