Safety Precautions

Before starting use

Air-conditioner usage target

The air-conditioner described in this catalog is a dedicated cooling/heating

device for human use.

Do not use it for special applications such as the storage of foodstuffs,

animals or plants, precision devices or valuable art, etc.

This could cause the quality of the items to drop, etc.

Do not use this for cooling vehicles or ships. Water leakage or current leaks

could occur.

Before use

Always read the "User,s Manual" thoroughly before starting use.

Installation

Always commission the installation to a dealer or specialist. Improper

installation will lead to water leakage, electric shocks and fires.

Make sure that the outdoor unit is stable in installation. Fix the unit to

stable base.

Usage place

Do not install in places where combustible gas could leak or where there

are sparks.

Installation in a place where combustible gas could be generated, flow or

accumulate, or places containing carbon fibers could lead to fires.

Refrigerant leakage

The refrigerant (R410A) used for Air conditioner is non-toxic and

inflammable in its original state.

However, in consideration of a state where the refrigerant leaks into the

room, measures against refrigerant leaks must be taken in small rooms

where the tolerable level could be exceeded. Take measures by installing

ventilation devices, etc.

Use in snowy areas

Take the following measures when installing the outdoor unit in snowy areas.

·Snow prevention

Install a snow-prevention hood so that the snow does not obstruct the air

intake port or enter and freeze in the outdoor unit.

·Snow piling

In areas with heavy snow fall, the piled snow could block the air intake

port. In this case, a frame that is 50cm or higher than the estimated snow

fall must be installed underneath the outdoor unit.

Automatic defrosting device

If the temperature is low, and the humidity is high, frost will stick to the

heat exchanger of the outdoor unit. If use is continued, the heating

performance will drop.

The "Automatic defrosting device" will function to remove this frost.

After heating for approx, three to ten minutes, it will stop, and the frost will

be removed. After defrosting, hot air will be blown again.

Servicing the air-conditioner

After the air-conditioner is used for several seasons, dirt will build up in

the air-conditioner causing the performance to drop. In addition to regular

servicing, we recommend the maintenance contract (charged for) by a

specialist.

Heating performance

The heating performance values (kW) described in catalog are the values

obtained by operating at an outdoor temperature of 7 C and indoor

temperature of 20 C as set forth in the ISO Standards. As the heating

performance decreases as the outdoor temperature drops, if the outdoor

temperature is too low and the heating performance is insufficient, use other

heating appliances as well.

Indication of sound values

The sound values are the values (A scale) measured in a chamber such as an

anechoic chamber following the ISO Standards. In the actual installation

state, the value is normally larger than the values given in the catalog due to

the effect of surrounding noise and echo. Take this into consideration when

installing.

Use in oil atmosphere

Avoid installing this unit in as atmosphere where oil scatters or builds up,

such as in a kitchen or machine factory.

If the oil adheres to the heat exchanger, the heat exchanging performance

will drop, mist may be generated, and the synthetic resin parts may deform

and break.

Use in acidic or alkaline atmosphere

If this unit is used in acidic atmosphere such as hot spring areas having high

level of sulfuric gases or in alkaline atmosphere including ammonia or

calcium chloride, places where the exhaust of the heat exchanger is sucked

in, or at coastal areas where the unit is subject to salt breezes, the outer plate

or heat exchanger, etc., will corrode. Please ask a dealer or specialist when

you use an air conditioner in places differing from a general atmosphere.

Use in places with high ceilings

If the ceiling is high, install a circulator to improve the heat and air flow

distribution when heating.
