Safety Check

After completing the electrical installation:
1. Grounding: After grounding the unit, measure the ground-
ing resistance by visually inspecting the unit and by us-
ing a grounding resistance tester, making sure the ground-
ing resistance is less than 4.0 ohms.
2. Electrical leakage check (to be performed during opera-
tion): During the test operation after complete installation
of the unit, the qualified installer may use the electroprobe
and multimeter to perform the electrical leakage check.
Turn off the unit immediately if leakage occurs.

Test Running

After completing the gas leak check at the flare nut connec-
tions and electrical safety check, perform the test operation.
• Ensure all tubing and wiring have been properly con-
nected.
• Make sure both the gas and liquid side service valves
are fully open.

2. Using the MODE button, select COOL, HEAT, AUTO and
FAN to ensure all the functions are operating.
3. When the ambient temperature is lower than 63°F (17°C),
the unit cannot be controlled by the remote control. To
run in cooling mode, operation can be done manually.
Manually controlling the unit is to be done only when the
remote control is disabled or maintenance is required.
• Grasp the panel sides and lift up the panel to an angle
where it remains fixed and a clicking sound is heard.
• Press the manual control button to select AUTO or COOL.
The unit will operate under forced AUTO or COOL mode
(see User's manual for more details).
4. Test operation should last approximately 30 minutes.
