1 SAFETY CONSIDERATIONS

Please read these “SAFETY CONSIDERATIONS” carefully before installing HRV and be sure to install it correctly.

The safety precautions listed here are divided into two categories.

In either case, important safety information is listed which must be read carefully.

WARNING .............	Failure to observe a warning may
	result in death or serious injury.
CAUTION ...............	Failure to observe a caution may result
	in injury or damage to the equipment.
	These too might lead to serious injury
	depending on the circumstances.

After completing the installation, make sure that the unit operates properly during the start-up operation. Please instruct the customer on how to operate the unit and keep it maintained.

Also, inform customers that they should store this installation manual along with the operation manual for future reference.

WARNING

•Ask your dealer or qualified personnel to carry out installation work. Do not try to install the machine yourself.

Improper installation may result in water leakage, electric shocks or fire.

•Installation should be done following the installation manual and no changes should be made to the unit.

Incorrect installation may cause leaking, electric shocks, or fire. Injuries may result if the HRV falls.

•Install the unit on a foundation strong enough to withstand the weight of the unit.

A foundation of insufficient strength may result in the equipment falling and causing injuries.

•Do not allow exhaust air to enter the outside air intake vent. This may cause the air of the room to become contaminated, harming the health.

•Locate the outside air intake vent so that it does not take in exhaust air which contains combustion air, etc.

Incorrect installation may cause a loss of oxygen in the room, leading to serious accidents.

•Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried out by qualified personnel according to local laws and regulations and this installation manual.

An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire. Insufficient power supply capacity or incorrect wiring may cause electrical shocks or fire.

•Use only accessories and manufacturer-specified parts when installing.

The use of parts other than specified may cause drop of the unit, water leakage, electric shock, fire or other accidents.

•Be sure to ground.

Do not connect the ground wire to gas or water pipes, lightning rod or a telephone ground wire.

Incomplete grounding may result in electric shocks.

•Make sure that all wiring is secured, the specified wires are used, and no external forces act on the terminal connections or wires. Improper connections or installation may result in overheating or fire.

•When wiring the power supply and connecting the remote controller wiring and transmission wiring, position the wires so that the electric parts box lid can be securely fastened. Improper positioning of the electric parts box lid may result in electric shocks, fire or the terminals overheating.

•When installing the unit in a small room, take measures against to keep refrigerant concentration from exceeding allowable safety limits in the event of refrigerant leakage. Contact the place of purchase for more information.

Excessive refrigerant in a closed ambient can lead to oxygen deficiency.

•If the refrigerant gas leaks during installation, ventilate the area immediately.

Toxic gas may be produced if the refrigerant gas comes into contact with fire.

•After completing the installation work, check that the refrigerant gas does not leak.

Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fire, such as a fan heater, stove or cooker.

•Do not directly touch any refrigerant which has leaked out of refrigerant piping connections, etc.

This may cause frostbite.

CAUTION

•Be sure to install an earth leakage breaker.

Failure to install an earth leakage breaker may result in electric shocks or fire.

•Install the indoor and outdoor units, power supply wiring and connecting wires at least 1 meter away from televisions or radios in order to prevent image interference or noise. (Depending on the radio waves, a distance of 1 meter may not be sufficient enough to eliminate the noise.)

•While following the instructions in this installation manual, install drain piping in order to ensure proper drainage and insulate piping in order to prevent condensation.

Improper drain piping may result in water leakage and property damage.

•Install the two outdoor ducts with down slope to prevent rainwater from entering the unit.

If this is not done completely, water may enter the building, may damage furniture, and cause electric shocks and fire.

•Insulate the two outdoor ducts and the supply air duct to prevent condensation.

If this is not done completely, water may enter the building, may damage furniture, etc.

•Insulate the duct and the wall electrically when a metal duct is to be penetrated through the metal lattice and wire lattice or metal lining of a wooden structure wall.

Inproper duct work may cause electric shocks or fire.

•Do not install the unit in the following locations:

a.Place subjected to high temperature or direct flame. May result in fire or overheating.

b.Where a mineral oil mist or an oil spray or vapor is produced, for example in a kitchen.

This may cause fire.

English

1

c.Place such as machinery plant and chemical plant where gas, which contains noxious gas or corrosive components of materials such as acid, alkali organic solvent and paint, is generated. Place where combustible gas leakage is likely.

Copper piping and brazed joints may corrode, causing refrigerant to leak or poisoning and fire due to leaked gas.

d.Place such as bathroom subjected to moisture. Electric leak or electric shocks and other failure can be caused.

e.Locations below freezing point.

Using the unit at temperatures below 0°C may cause the drain pan the supply and discharge piping, the humidifying element, the solenoid valves, and other parts to freeze, which can cause accidents.

f.Near machinery emitting electromagnetic waves. Electromagnetic waves may disturb the operation of the control system and result in a malfunction of the equipment.

•Make sure the temperature and humidity near the unit and the air suction/discharge air grille is within limit dictated by the usage conditions.

Do not install in refrigerated truck or other locations with low temperatures or near heated pools.

This may cause fires or short circuits.

•Make sure that a snow protection measure is taken. If no protection snow may enter through the outdoor ducts, and cause damaging furniture and electric shock and fire.

2 BEFORE INSTALLATION

The accessories needed for installation must be retained in your custody until the installation work is completed. Do not discard them!

After carrying in the unit, protect it with packing materials to prevent it from scratching until installation work is done.
