Operation; Auxiliary Heat - Rheem RQPM 15/16 Seer Series Installation Instructions Manual

7. Is compressor running correctly.
8. Turn thermostat system switch to "HEAT." Unit should stop. Wait 5 minutes, then
raise temperature setting to above room temperature. Unit should run in heating
mode and after about 30 to 50 seconds auxiliary heaters, if installed, should come
on.
9. Check the refrigerant charge using the instructions located on control box cover.
Replace service port caps. Service port cores are for system access only and will
leak if not tightly capped.
10 Turn thermostat system switch to proper mode "HEAT" or "COOL" and set thermostat
to proper temperature setting. Record the following after the unit has run some time.
A. Operating Mode _______________________________
B. Discharge Pressure (High) ___________________PSIG
C. Vapor Pressure at Compressor (Low) __________PSIG
D. Vapor Line Temperature at Compressor __________°F.
E. Indoor Dry Bulb______________________________°F.
F. Indoor Wet Bulb _____________________________°F.
G. Outdoor Dry Bulb ____________________________°F.
H. Outdoor Wet Bulb ____________________________°F.
I. Voltage at Contactor ________________________Volts
J. Current at Contactor _______________________Amps
K. Model Number_________________________________
L. Serial Number _________________________________
M.Location______________________________________
N. Owner _______________________________________
O. Date_________________________________________
11. Adjust discharge air grilles and balance system.
12. Check ducts for condensation and air leaks.
13. Check unit for tubing and sheet metal rattles.
14. Instruct the owner on operation and maintenance.
15. Leave "USE AND CARE" instructions with owner.
XV. OPERATION
Most single phase units are not equipped with start relay or start capacitor. It is impor-
tant that such systems be off for a minimum of 5 minutes before restarting to allow
equalization of pressures. Do not move the thermostat to cycle unit without waiting five
minutes. To do so may cause the compressor to stop on an automatic open overload
device or blow a fuse. Poor electrical service can cause nuisance tripping in overloads
or blow fuses.
IMPORTANT: The compressor has an internal overload protector. Under some condi-
tions, it can take up to 2 hours for this overload to reset. Make sure overload has had
time to reset before condemning the compressor.
These units may be equipped with a time delay control (TDC1). The control allows the
blower to operate for 45 to 90 seconds after the thermostat is satisfied.
XVI. AUXILIARY HEAT
The amount of auxiliary heat required depends on the heat loss of the structure to be
heated and the capacity of the heat pump. It is good practice to install strip heat to main-
tain at least 60°F indoor temperatures in case of compressor failure. The auxiliary heat
is energized by the first stage of the thermostat. The amount of electric heat that is
allowed to come on, as determined by the output of the heat pump, may be controlled by
an outdoor thermostat.
WARNING
ONLY ELECTRIC HEATER KITS SUPPLIED BY THIS MANUFACTURER AS
DESCRIBED IN THIS PUBLICATION HAVE BEEN DESIGNED, TESTED, AND
EVALUATED BY A NATIONALLY RECOGNIZED SAFETY TESTING AGENCY
FOR USE WITH THIS UNIT. USE OF ANY OTHER MANUFACTURED ELECTRIC
HEATERS INSTALLED WITHIN THIS UNIT MAY CAUSE HAZARDOUS CONDI-
TIONS RESULTING IN PROPERTY DAMAGE, FIRE, BODILY INJURY OR
DEATH.
A. CONTROL SYSTEM OPERATION
1. In the cooling mode, the thermostat will, on a call for cooling, energize the com-
pressor contactor and the indoor blower relay. The indoor blower can be operated
continuously by setting the thermostat fan switch at the "ON" position.
