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 eld-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 6.
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
until you have consulted with the power company and
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.
