APPENDIX 2 - FACTORY RUN TEST PROCEDURE

Prompt Message #2

ROTATION CORRECT? – As the supply fan coasts 

down, you can open the door and verify proper rota-

tion. Press the check key if the rotation is correct. If 

not, identify why the rotation is wrong, and correct.
If both messages are accepted, PASS will be indicated 

at the display. Use the down arrow key to move to the 

next test.

COMPRESSOR SYSTEM TEST

(A, B, on all units; C and D on units 39 tons and great-

er; E and F on units 100 tons and greater).

To initiate the test press the check key (√ ). The control 

will ask you ARE YOU SURE? Press the check key 

(√ ) again.

Once underway, the controller will perform the fol-

lowing sequence:

1.  Set COMPRESSOR A to ON. 
2.  Wait 5 Seconds.
3.  Turn COMPRESSOR A to OFF.

Prompt Message #1

ROTATION CORRECT FOR 1A? – To verify proper 

rotation you need to attach a gauge set to the com-

pressor system prior to conducting the test. If rota-

tion is correct, the discharge pressure should increase 

rapidly. If the discharge and suction pressures remain 

the same, the rotation is not correct. Press the check 

key (√ ) if the compressor rotation is correct.

During this test sequence, the supply fan 

blower will operate at 50 hertz. Make sure 

this speed will not result in a static pres-

sure which could damage the building 

supply duct system.

Perform the following:

1.  Set the SUPPLY FAN to ON.
2.  Set SUPPLY FAN VFD AO to 60%.
3.  Wait 30 Seconds.
4.  Set COMPRESSOR A to ON.
5.  Wait 180 seconds.
6.  Set COMPRESSOR A to OFF.

7.  Wait 10 seconds.
8.  PASS will be indicated for this test and all outputs 

will be turned OFF.

If at any time during this test, the Com-

pressor System #1 status is not OKAY, all 

outputs will be immediately turned OFF 

and FAIL will be indicated for the test.

Repeat the above procedure for each of the compressor 

systems.

ANALOG OUTPUT OPERATION TEST

To initiate the test press the check key (√ ). The control 

will ask you ARE YOU SURE? Press the check key 

(√ ) again.

Once underway, the Unit Controller will perform the 

following sequence:

1.  Set OUTSIDE AIR / RETURN DAMPER to 

50%. 

2.  Set the CONDENSER WATER VALVE to 50%.
3.  Set the CONDENSER BYPASS VALVE (if pres-

ent) to 50%.

4.  Set the HOT WATER / STEAM VALVE (if pres-

ent) to 50%.

5.  Wait 45 seconds.

Prompt Message #1

ALL DAMPERS OPEN 50%? – Check the above ac-

tuators and verify they are approximately 50%. If they 

are press the ACCEPT - check key (√ ). 

If the actuators operated properly, use the down arrow 

key to move to the next test.

STAGED ELECTRIC HEAT TEST

This test can be run in one of two ways. The electri-

cal circuit could be checked without turning on the 

heaters by removing the fuses feeding the electric heat 

elements. Or if the fuses are left in place, the heater 

elements will be energized. If the heater elements are 

energized, the supply fan must be turned on or there is 

a possibility the limits will trip. The following proce-

dure will turn on the supply fan:
