15. If checking the unit in the wintertime, when the outdoor coil

is cold enough to actuate the defrost control, observe at
least one defrost cycle to make sure the unit defrosts
completely.

Final System Checks

16. Check to see if all supply and return air grilles are adjusted

and the air distribution system is balanced for the best
compromise between heating and cooling.

17. Check for air leaks in the ductwork.

18. See Sections on 

Air Flow Measurement and Adjustment

and 

Checking Charge

.

19. Make sure the unit is free of “rattles”, and the tubing in the

unit is free from excessive vibration. Also make sure tubes
or lines are not rubbing against each other or sheet metal
surfaces or edges. If so, correct the trouble.

20. Set the thermostat at the appropriate setting for cooling

and heating or automatic changeover for normal use.

21. Be sure the Owner is instructed on the unit operation, filter,

servicing, correct thermostat operation, etc.

The foregoing “Start-up Procedure and Check List” is
recommended to serve as an indication that the unit will
operate normally.

COMPONENTS

1.

Contactor

 - This control is activated (closed) by the room

thermostat for both heating and cooling. The contactor has
a 24V coil and supplies power to the compressor and
outdoor fan motor.

2.

Crankcase Heater – 

This item is “ON” whenever power

 

is

supplied to the unit. It warms the compressor crankcase
thereby preventing liquid migration and subsequent
compressor damage. The insert type heater is self
regulating.  It is connected electrically to the contactor L1
and L2 terminals.

3.

Condenser Motor - 

This item is activated by the contactor

during heating and cooling, except during defrost and
emergency heat operation.
