Unit Start-Up
IMPORTANT
Units should be energized 24 hours before unit start-up
to prevent compressor damage as a result of slugging.
1. Inspect all factory- and field-installed wiring for loose
connections.
2. Verify that the manifold gauge set is connected.
3. Add additional refrigerant charge if required before
opening valves and while system is still under a
vacuum.
4. Open the liquid and suction line service valves to
release the refrigerant charge contained in outdoor
unit into the system.
5. Replace the stem caps and tighten to the value listed
in "Table 1. Torque Requirements" on page 8.
6. Check voltage supply at the outdoor unit terminal strip.
The voltage must be within the range listed on the
unit's nameplate. If not, do not start the equipment

the voltage condition has been corrected.
7. Refer to the included user guide to operate the system
using the provided remote control.
8. Visually check for binding of both indoor and outdoor
fans.
Adding Refrigerant for Longer Line Set
The outdoor unit is factory-charged with refrigerant.
Calculate the additional refrigerant required according to
the diameter and the length of the liquid pipe between the
outdoor unit and indoor unit connections.
Be sure to add the proper amount of additional refrigerant.
Failure to do so may result in reduced performance.
Maximum line set length is 213 feet (65 meters).
