Operating Manual

CAUTION

1. This unit requires no additional refrig-

erant charge up to 100 ft. tubing length.

In case of more than 100 ft., additional

refrigerant charge is required.

2. In case of multi type installation, indoor

units should be installed within the

same room. If multi type indoor units

are installed in different rooms, tem-

perature control may develop problems

because thermostat operation must

follow the thermostat condition of 1

indoor unit only (the main unit).

WARNING

Always check the gas density

for the room in which the unit is

installed.

CAUTION

Pay special attention to any

location, such as a basement

or recessed area, etc. where

leaked refrigerant can collect,

since refrigerant gas is heavi-

er than air.

■ Check of limit density

When installing an air conditioner in a room, it is neces-

sary to ensure that even if the refrigerant gas acciden-

tally escapes, its density does not exceed the limit level

for that room.
