WARNING
• All electrical wiring must not touch the water piping or any moving parts of the fan motors.
• Confirm that the unit has been switched OFF before installing or servicing the unit.
• Disconnect from the main power supply before servicing the air conditioner unit.
• DO NOT pull out the power cord when the power is ON.
This may cause serious electrical shocks which may result in fire hazards.
• Keep the indoor and outdoor units, power cable and transmission wiring, at least 3.5 ft from TVs and radios, to prevent distorted
pictures and static.
Depending on the type and source of the electrical waves, static may be heard even when more than 1m away.
• Do not use means to accelerate the defrosting process (if applicable) or to clean, other than those recommended by the
manufacturer.
• The appliance must be stored in a room without continuously operating ignition sources (for example: open flames, an operating
gas appliance or an operating electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• Piping material, pipe routing, and installation including protection from physical damage in operation and service, shall be in
compliance with national and local codes and standards, such as ASHRAE 15, IAPMO Uniform Mechanical Code, ICC International
Mechanical Code, or CSA B52. All field joints shall be accessible for inspection prior to being covered or enclosed.
CAUTION
• Do not install the air conditioner at any place where there is danger of flammable gas leakage.
In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out.
• While following the instructions in this installation manual, install drain piping to ensure proper drainage and
insulate piping to prevent condensation.
Improper drain piping may result in indoor water leakage and property damage.
• Tighten the flare nut according to specified method such as with a torque wrench.
If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage.
• Do not overcharge the unit.
This unit is factory pre-charged. Overcharge will cause over-current or damage to the compressor.
• Ensure that the unit's panel is closed after service or installation.
Unsecured panels will cause the unit to operate noisily.
• Sharp edges and coil surfaces are potential locations which may cause injury hazards.
Avoid being in contact with these places.
• Before turning off the power supply set the remote controller's ON/OFF switch to the "OFF" position to prevent accidental tripping of
the unit.
If this is not done, the unit's fans will start turning automatically when power resumes, posing a hazard to service personnel or the user.
• Make sure to provide for adequate measure in order prevent that the outdoor unit be used as a shelter by small animals. Small
animal making contact with electrical parts can cause malfunctions, smoke or fire.
Please instruct the customer to keep the area around the unit clean.
• The temperature of refrigerant circuit will be high, please keep the inter-unit wiring away from copper pipes that
are not thermally insulated.
• Only qualified personnel can handle, fill, purge and dispose of the refrigerant.
