Heat pump liquid and suction valves are closed to contain
the charge within the unit. The unit is shipped with the valve
stems closed and caps installed. Do not open valves until
the indoor unit and line set is evacuated.

1. Connect the vacuum pump with 250 micron capability
to the service valves.
2. Evacuate the system to 500 microns or less using
suction and liquid service valves. Using both valves
is necessary.
3. Close pump valve and hold vacuum for 10 minutes.
Typically pressure will rise during this period.
• If the pressure rises to 500 microns or less and
remains steady the system is considered leak-free;
proceed to start-up.
• If pressure rises above 500 microns moisture and/
or noncondensibles may be present or the system
may have a small leak. Return to step 2: If the same
result is encountered check for leaks as previously
indicated and repair as necessary then repeat
evacuation.

The heat pump rating plate lists pertinent electrical data nec-
essary for proper electrical service and overcurrent protection.
Wires should be sized to limit voltage drop to 2% (max.) from
the main breaker or fuse panel to the heat pump. Refer the
NEC, CEC, and all local codes to determine the correct wire
gauge and length.
Local codes often require a disconnect switch located near
the unit; do not install the switch on the unit.
o
Vercurrent
The inverter control system software provides sufficient time
delay to protect from overcurrent conditions and permit the
compressor and fan motors to adjust their rotational speed.
