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.
XIV.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 are equipped with a time delay control (TDC1). The control allows the blow-
er to operate for 45 to 90 seconds after the thermostat is satisfied.
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.
2. In the heating mode, the first heat stage of the thermostat will energize one or
more supplementary resistance heaters. If required or considered desirable, the
resistance heat may also be controlled by outdoor thermostats. In the heating
mode, the thermostat will, on a call for heating, energize the indoor blower relay.
