Once the previously described conditions are met, follow these guidelines when the
wiring is carried out:
• Always have an individual power circuit specifically for the air conditioner. Always
follow the circuit diagram posted on the inside of the control cover.
• Screws fastening the wiring in the casing of electrical fittings may come loose dur-
ing transportation. Because loose screws may cause wire burn-out, check that the
screws are tightly fastened.
• Check the specifications for the power source.
• Confirm that electrical capacity is sufficient.
• Confirm that starting voltage is maintained at more than 90 percent of the rated
voltage marked on the name plate.
• Confirm that the cable thickness is as specified in the power source specifications.
• Always install an earth leakage circuit breaker in wet or moist areas.
• The following can be caused by a drop in voltage: vibration of a magnetic switch,
damaging the contact point, broken fuses, and disturbance of normal functioning.
• Disconnection from a power supply must be incorporated into the fixed wiring. It
must have an air gap contact separation of at least 3mm in each active (phase) con-
ductors.
• Before accessing terminals, all supply circuits must be disconnected.
9 - AIR EVACUATION
Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can damage the
air conditioner, reduce its efficiency, and cause injury.
Use a vacuum pump and manifold gauge to evacuate the refrigerant circuit, removing any non-condensable
gas and moisture from the system.
Evacuation should be performed upon initial installation and when unit is relocated.
BEFORE PERFORMING EVACUATION
•
Check to make sure the connective pipes between the indoor and outdoor units are connected
properly.
•
Check to make sure all wiring is connected.
Before using a manifold gauge and a vacuum pump, read their operation manuals to make sure you know
how to use them properly.
1. Connect the manifold gauge charge hose to the
service port on the outdoor unit's low pressure
valve.
2. Connect the manifold gauge charge hose from
the to the vacuum pump.
3. Open the Low Pressure side of the manifold
gauge. Keep the High Pressure side closed.
4. Turn on the vacuum pump to evacuate the system.
5. Run the vacuum for at least 15 minutes, or until
the Compound Meter reads -76cmHG (-1x105Pa).
6. Close the manifold gauge Low Pressure valve and turn off the vacuum pump.
7. Wait for 5 minutes, then check that there has been no change in system pressure.
If there is no change in system pressure, unscrew the cap from the packed valve (high pressure
valve). If there is a change in system pressure, there may be a gas leak.
