CAUTION
THE COMPRESSOR HAS AN INTERNAL OVERLOAD PROTECTOR. UNDER
SOME CONDITIONS, IT CAN TAKE UP TO 2 HOURS FOR THIS OVERLOAD
TO RESET. MAKE SURE OVERLOAD HAS HAD TIME TO RESET BEFORE
CONDEMNING THE COMPRESSOR.

11.1 Evacuation Procedure

Evacuation is the most important part of the entire service procedure. The life and
efficiency of the equipment is dependent upon the thoroughness exercised by the
serviceman when evacuating air and moisture from the system.
Air in the system causes high condensing temperatures and pressure, resulting in
increased power input and non-verifiable performance.
Moisture chemically reacts with the refrigerant and oil to form corrosive hydrofluoric
and hydrochloric acids. These attack motor windings and parts, causing breakdown.
After the system has been leak checked and proven sealed, connect the vacuum
pump and evacuate system to 500 microns. The vacuum pump must be connected
to both the high and low sides of the system through adequate connections. Use
the largest size connections available since restrictive service connections may lead
to false readings because of pressure drop through the fittings.
IMPORTANT: Compressors (especially scroll type) should never be used to evacu-
ate the air conditioning system because internal electrical arcing may result in a
damaged or failed compressor.
With thermostat in the "Off" position, turn the power on to the furnace and the heat
pump. Start the heat pump and the furnace with the thermostat. Make sure the
blower is operating.

Comfort Control
12.1 Control Description (see Figure 4)
Dual 7-Segment LED
• Displays status and diagnostic codes (See Status and Diagnostic Description)
• Displays diagnostic/fault recall (See Test Mode/Fault Recall)
Red LED (Y1)
• Y1 red LED (solid on) indicates Y1 call from thermostat is present
CAUTION
UNIT MAY START SUDDENLY AND WITHOUT WARNING
Solid red light indicates a thermostat call for unit operation is present at
the ICC control. ICC control will attempt to start unit after short cycle timer
expires or when in Active Protection mode will attempt to restart unit prior
to Lockout mode.
