Safety Precautions
[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 "Instruction 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.
Use the MHI-designated products for the accessories such as the air purifier, humidifier, and auxiliary electric heater for heating.
Always commission the installation to a dealer or specialist. lmproper installation will lead to water leakage, electric shocks and fires.
[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.
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 insufficent, 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 an acidic or alkaine atmosphere such as hot spring
areas having high levels of sulfuric gases, 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. Use the
anti-corrosion specification model at places differing from a general
atmosphere.
Use in places with high ceilngs
If the ceiling is high, install a circulator to improve the heat and air flow
distrbution when heating.
Refrigerant leakage
The refrigerant gas (R-22) used for the building multi 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 fall
Install a now-prevention hood so that the snow does not obstruct the air
intake port, and so that the snow does not 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.
Serving 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
specilist.
