• Do not place any combustion appliance in a place where it is directly
exposed to the wind of Air to Air Heat Exchange with DX Coil unit,
otherwise it may cause imperfect combustion.
• If refrigerant gas has leaked during the installation work, ventilate the
room immediately. If the leaked refrigerant gas comes in contact with
fire, noxious gas may be generated.
• After the installation or servicing work, check the refrigerant gas does
not leak.
• If refrigerant gas leaks in the room, poisonous gas generates when
gas touches to fire such as fan heater, stove or cooking stove though
the refrigerant gas itself is innocuous.
• Inspect the Air to Air Heat Exchanger with DX Coil Unit for any falling
hazard of the unit before maintenance or repair.
• Do not modify the products. Do not also disassemble or modify the
parts. It may cause a fire, electric or injury.
• This appliance is intended to be used by expert or trained users in
shops, in light industry, or for commercial use by lay persons.
Selection of installation location
• Install the Air to Air Heat Exchanger with DX Coil Unit securely in a
location where the base can sustain the weight adequately. If the
strength is insufficient, the unit may fall down resulting in human
injury.
• Do not install the unit in places 1) with high temperature 2) where the
unit is subject to direct fire 3) where much oil smoke is generated.
Otherwise, a fire may result.
• Do not install the unit in a machinery factory or a chemical plant,
where a toxic gas containing acid, alkali, an organic solvent, or paint,
or a gas containing a corrosive substance is generated. Gas
poisoning or a fire may result.
• Do not install in a location where flammable gas may leaks are
possible. If the gas leak and accumulate around the unit, it may ignite
and cause a fire.
• Install the unit so that the air discharge is located at least 1.5 m from
the nearest fire alarm. Otherwise, when a fire occurs, the fire alarm
may be late to detect it, or may not detect it at all.
Installation
• Transport it by the truck or the forklift. Transport it by six people or
more when the person transports it temporarily. The waist etc. might
be hurt when not following it.
• When transporting the Air to Air Heat Exchanger with DX Coil Unit,
wear shoes with additional protective toe caps, protective gloves, and
other protective clothing.
• When transporting the Air to Air Heat Exchanger with DX Coil Unit, do
not take hold of the bands around the packing carton. You may injure
yourself if the bands should break.
• When the Air to Air Heat Exchanger with DX Coil Unit is to be
suspended, the designated hanging bolts (M12) and nuts (M12) must
be used
• Install the Air to Air Heat Exchanger with DX Coil Unit at enough
strong place to withstand the weight of the unit. If the strength is not
enough, the unit may fall down resulting in injury
• Follow the instructions in the Installation Manual to install the Air to Air
Heat Exchanger with DX Coil Unit. Failure to follow these instructions
may cause the product to fall down or topple over or give rise to noise,
vibration, water leakage, etc.
• Wear protective gloves and safety work clothing during installation,
servicing and removal.
• Do not touch the aluminum fin of the Air to Air Heat Exchanger with
DX Coil Unit or outdoor unit. You may injure yourself if you do so. If
the fin must be touched for some reason, first put on protective gloves
and safety work clothing, and then proceed.
• Tighten the flare nut with a torque wrench in the specified manner.
Excessive tighten of the flare nut may cause a crack in the flare nut
after a long period, which may result in refrigerant leakage.
• When working at heights, put a sign in place so that no-one will
approach the work location, before proceeding with the work. Parts
and other objects may fall from above, possibly injuring a person
below.
• Before starting to install the Air to Air Heat Exchanger with DX Coil
Unit, read carefully through the Installation Manual, and follow its
instructions to install the Air to Air Heat Exchanger with DX Coil Unit.
• Only a qualified installer (*1) or qualified service person (*1) is
allowed to install the Air to Air Heat Exchanger with DX Coil Unit. If
the Air to Air Heat Exchanger with DX Coil Unit is installed by an
unqualified individual, a fire, electric shocks, injury, water leakage,
noise and/or vibration may result.
