6.6.3. Evacuation
Because this system has an EXV for the heating expansion device, additional steps must be
taken to open the EXV if the heat pump unit must be evacuated for service reasons. If the EXV
is not open when pulling a vacuum or recovering refrigerant from the heat pump unit, extended
evacuation time may be required and/or inadequate vacuum obtained. The control has
provisions to open the EXV for refrigerant recovery and/or evacuation.
• Set desired time period. Default time period for procedure is 120 minutes.
• Touch START on Ion System Control or service tool to open the valve.
• Begin evacuation or refrigerant recovery as required for the procedure after control indicates
the EXV is open. Power may be removed from heat pump after the control indicates
“READY TO EVACUATE.”
