Unit installation

11. CHECKOUT

1. Before engaging power to any system, insure the

following:

A) All tools have been removed from the

equipment.

B) All wiring is attached, routed and properly

secured.

C) All panels (both mechanical and electrical)

are in place.

D) The thermostat system switch is placed into

the “OFF” position and fan switch is placed

in the “Auto” position.

E) All co-workers have been warned that the

equipment is being energized.

2. System wiring may be checked by referring to the

wiring diagram located on the back of the wiring box

door.

3. Before beginning the checkout procedure, thoroughly

read the instructions in either the thermostat

installation instructions or in the owners manual

provided with this product.

Keep in mind that the wall thermostat provides a

3 minute delay between off and on cycles.

There is also a 30 second delay between 1

and 2

stage cooling. This is to prevent both compressors

from starting simultaneously. To insure that the

thermostat calls for both 1

and 2

stage cooling,

verify that the cool setpoint is well below actual

indoor temperature.

4. After complying with steps 1 through 3, engage

power to all systems and begin checkout procedure.

5. Test each thermostat function, such as fan modes,

heat modes and cool modes to insure proper

operation.
