OPERATION PROCEDURE
1. Plug the power cord into an appropriate power outlet.
2. Make sure that all the emergency stop buttons are disabled.
3. Power on the A/C system input switch.
4. Power on the motor using the key switch.
5. Make sure that the compressor speed reaches 750 rpm.
6. Power on the DC switch. The DC power indicator lamp should be ON.
7. Switch the Auto OFF to AUTO.
8. Use the MCC Control Module to operate the HVAC.
9. Make sure that ATS adjustment knob is set to minimum.
Note 1: The HVAC system has been modified for half capacity of its operation. A
section of the evaporator and another one of the blower motor have been
removed. CFM2 and CFM4 fans are disconnected.
Note 2: The HVAC system contains half the amount of the refrigerant charge
(R134A = 10 lb).
Note 3: The HVAC system is driven by a 15hp electric motor connected to an
appropriate power outlet. The motor has been programmed to permit the
compressor to reach a speed of 750 rpm.
