To eliminate erratic operation, seal the hole in the wall at the
thermostat with permagum or equivalent to prevent air drafts
affecting the anticipators in the thermostat.
Route the control wiring into the outdoor unit through the hole
provided. Connect the control wiring, per Figure 8.
EVACUATION
It will be necessary to evacuate the system if the unit has
developed a leak during shipment or was, for any other reason,
opened to the atmosphere. If a leak is suspected, leak test to
locate the leak. Repair the leak and test again.
WARNING:Never attempt to repair any brazed connections
while the system is under pressure. Personal injury
could result.
Evacuate the system down to at least 1,000 microns.
To verify if the system has no leaks, simply close the valve to
the vacuum pump suction to isolate the pump and hold the
system under vacuum. Watch the micron gauge for a few
minutes. If the micron gauge indicates a steady and continuous
rise, it’s an indication of a leak.
If the gauge shows a rise, then levels off after a few minutes
and remains fairly constant, its an indication the system is leak
free, but still contains moisture and may require further evacu-
ation if the reading is above 1000 microns.

* These orifices are factory-mounted in the flow control device of each indoor coil.
**These orfices are packed in the instruction/warranty packet of each outdoor unit.
NOTE: If orifice required is
not supplied
in coil or in the outdoor unit instruction packet, the orifice in ( ) must be ordered from the
Parts Department.
NOTE 2: Due to scroll compressor, hard start components are not required when using coils with TXV or Solenoid Valve kits.
