...In a Room
Properly insulate any tubing run inside a room to prevent "sweating" that can cause drip-
ping and water damage to walls and floors.
...In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame.
Provide a suitable air baffle.
...In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than drifting snow.
When Connecting Refrigerant Tubing
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before
connecting them, then tighten the nut with a torque wrench for a leak-free connection.
• Check carefully for leaks before opening the refrigerant valves.
When Servicing
• Turn the power OFF at the main circuit breaker panel before opening the unit to check
or repair electrical parts and wiring.
• Keep your fingers and clothing away from any moving parts.
• Clean up the site after you finish, remembering to check that no metal scraps or bits of
wiring have been left inside the unit being serviced.
• After installation, explain correct operation to the customer, using the operating manual.
Never touch electrical components immediately after the power supply has been turned
off. Electric shock may occur. After turning off the power, always wait 5 minutes before
touching electrical components.
If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant
comes in contact with a flame, it produces a toxic gas.
Do not attempt to install the air conditioner or a part of the air conditioner by yourself.
This unit must be installed by qualified personnel with a capacity certificate for handling
refrigerant fluids. Refer to regulation and laws in use on installation place.
This unit is part of a set constituting an air conditioner. It must not be installed alone or
with a device non-authorized by the manufacturer.
Always use a separate power supply line protected by a circuit breaker operating on all
wires with a distance between contact of 1/8 in. (3 mm) for this unit.
The unit must be correctly earthed (grounded) and the supply line must be equipped
with a differential breaker in order to protect the persons.
The units are not explosion proof and therefore should not be installed in explosive
atmosphere.
When moving, consult authorized service personnel for disconnection and installation
of the unit.
Do not place any other electrical products or household belongings under indoor unit or
outdoor unit.
Dripping condensation from the unit might get them wet, and may cause damage or
malfunction of your property.
