Seasonal Wind And Cautions In Winter; Connecting Cables; General Consideration - LG THERMA V AHBW036H0 Quick Manual

Seasonal Wind and Cautions in Winter

• Sufficient measures are required in a snow area or severe cold area in winter so that unit can be operated well.
• Get ready for seasonal wind or snow in winter even in other areas.
• Install a suction and discharge duct not to let in snow or rain.
• Install the unit not to come in contact with snow directly. If snow piles up and freezes on the air suction hole, the
system may malfunction. If it is installed at snowy area, attach the hood to the system.
• Install the unit at the higher installation console by 500mm than the average snowfall (annual average snowfall)
if it is installed at the area with much snowfall.
• Where snow accumulated on the upper part of the unit by more than 100mm, always remove snow for operation.
1. The height of H frame must be more than 2 times the snowfall and its width shall not exceed the width of
the unit. (If width of the frame is wider than that of the unit, snow may accumulate.)
2. Don't install the suction hole and discharge hole of the unit facing the seasonal wind.

Connecting Cables

General consideration

Followings should be considered before beginning unit wiring.
• Field-supplied electrical components such as power switches, circuit breakers, wires, terminal
boxes, etc should be properly chosen with compliance with national electrical legislation or regula-
tion.
• Make it sure that supplied electricity is enough to operate the unit, electric heater, water tank
heater, etc. The capacity of fuse also selected according to the power consumption.
• The main electricity supply should be dedicated line. Sharing main electricity supply with other
devices such as washing machine or vacuum cleaner is not permitted.
CAUTION
• Before starting wiring job, the main electricity supply should be turned off until wiring is completed.
• When adjusting or changing wiring, the main electricity supply should be turned off and ground wire
should be connected securely.
• Installation place should be free from the attack of wild animal. For example, mice's wire attacking
or frog's entering into the unit may cause critical electrical accident.
• All power connections should be protected from dew condensation by thermal insulation.
• All electrical wiring should comply with national or local electrical legislation or regulation.
• The ground should be connected exactly. Do not earth the unit to the copper pipe, steel fence at
the veranda, city water outlet pipe, or any other conductivity materials.
• Fix all cable using cord clamp tightly. (When cable is not fixed with cord clamp, use additionally
supplied cable ties.)
