Haier AC422AFERA installation manual Specifications, Temperature and Humidity Range, Cautions

Cautions

All electrical repairs must be carried out by qualified electricians. Inadequate repairs may result in a major source of danger for the user of the air conditoiner.

Do not damage any parts of the air conditioner that carry refrigerant by piercing or perforating the air conditioner's tubes with sharp or pointed items, crushing or twisting any tubes, or scraping the coatings off the surfaces. If the refrigerant spurts out and gets into eyes, it may result in serious eye injuries.

Do not obstruct or cover the ventilation grille of the air conditioner. Do not put fingers or any other things into the inlet/outlet and swing louver.

Do not allow children to play with the air conditioner. In no case should children be allowed to sit on the outdoor unit.

When the indoor unit is turned on,the PCB will test if swing motor is O.K.,and then fan motor will start up.So there is a few seconds to wait .

In cooling mode,the flaps will swing automatically to a fixed position for anti- condensating.

Specifications

The refrigerating circuit is leak-proof.

For this model, the all-pole discon-rexion connection method should be applied in the power supply.

Such means for disconnection must be incorporation in the fixed wiring.

If the air conditioner is used under higher temperature condition than those listed, the built-in protection circuit may operate to prevent internal circuit damage. Also, during Cooling and Dry modes, if the unit is used under conditions of lower temperature than those listed above, the heat-exchanger may freeze, leading to water leakage and other damage.

Do not use this unit for any other purposes except for the Cooling and the Heating, Dehumidifying, and air-circulation of rooms should be in ordinary dwellings.

The wiring method should be in line with the local wiring standand.

The waste battery should be disposed properly.

If the fuse on PC board is broken, please change it with the type T 3.15A/250VAC. The air breaker should be all-pole switch. and the distance between it's two contacts should no less than 3mm.
