1. SAFETY PRECAUTIONS

Please read these “SAFETY PRECAUTIONS” carefully before installing HRV and be sure to install it correctly. After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate the air conditioner and take care of it with the aid of the operation manual. Ask the customer to store the installation manual along with the operation manual for future reference.

This HRV comes under the term “appliances not accessible to the general public”.

Meaning of WARNING and CAUTION notices.

WARNING..............Failure to follow these instructions

properly may result in personal injury or loss of life.

CAUTION...............Failure to observe these instructions

properly may result in property damage or personal injury, which may be serious depending on the circumstances.

WARNING

• Ask your dealer or qualified personnel to carry out installation work. Do not attempt to install the air conditioner 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. Improper installation may result in water leakage, 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.

• Be sure to use only the specified accessories and parts for installation work. Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire.

• Carry out the specified installation work after taking into account strong winds, typhoons or earthquakes. Failure to do so during installation work may result in the unit falling and causing accidents.

• Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal connections or wires. Improper connections or securing of wires may result in abnormal heat build-up or fire.

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

• Be sure to switch off the unit before touching any electrical parts.

• Be sure to earth the HRV. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks or fire. A high surge current from lightning or other sources may cause damage to the air conditioner.

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

CAUTION

• Install the indoor and outdoor units, power cord and connecting wires at least 1 meter away from televisions or radios to prevent picture interference and noise. (Depending on the incoming signal strength, a distance of 1 meter may not be sufficient to eliminate noise.)

• 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. Improper duct work may cause electric shocks or fire.

• Do not install the unit in the following locations:

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

2. Where there is a high concentration of mineral oil spray or vapour (e.g. a kitchen). This may cause fire.

3. 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.

4. Near machinery emitting electromagnetic radiation. Electromagnetic radiation may disturb the operation of the control system and result in a malfunction of the unit.

1 English

5. Where flammable gas may leak, where there is carbon fibre or ignitable dust suspensions in the air, or where volatile flammables such as paint thinner or gasoline are handled. Operating the unit in such conditions may result in fire.

• The HRV is not intended for use in a potentially explosive atmosphere.

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

1. Refrigerated truck or other locations with low temperatures.

2. Place such as bathroom or heated pools subjected to moisture.

This may cause fires or electric leak or electric shocks.

• 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.

• In areas where insects are easily attracted to a light, such as where there is a window or light near a ventilation opening, extremely small insects can sometimes infiltrate the room by passing through the ventilation opening. Since totally preventing against infiltration by extremely small insects is difficult, it is important to consider a serious solution like a filter box (field supply) during the design process to protect against insect infiltration.

BEFORE INSTALLATION

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

1. Decide upon a line of transport.

2. Leave the unit inside its packaging while moving, until

reaching the installation site. Where unpacking is unavoidable, use a sling of soft material or protective plates together with a rope when lifting, to avoid damage or scratches to the unit.

Hold the unit by the hanger brackets (4) when opening the crate and moving it, and do not lift it holding on to any other part (especially the duct connecting flange).

2-1 PRECAUTIONS

• Be sure to instruct customers how to properly operate the unit (especially maintenance of air filter, and operation procedure) by having them carry out operations themselves while looking at the manual.

3. SELECTING INSTALLATION SITE

CAUTION

• When moving the unit during or after unpacking, make sure to lift it by holding its hanger brackets. Do not exert any pressure on other parts, especially duct connecting flange.

• Please attach additional thermal insulation material to the unit body when it is believed that the temperature and the relative humidity in the ceiling exceed 30°C and 80%. Use glass wool, polyethylene foam, or similar with a thickness of 10 mm or more as thermal insulation material.

(1)Select an installation site where the following conditions

are fulfilled and that meets with your customer’s approval.

• Install in a place which has sufficient strength and stability. (Beams, ceiling, and other locations capable of fully supporting the weight of the unit.) Insufficient strength is dangerous. It may also cause vibration and unusual operating noise.

• Where nothing blocks air passage.

• Do not install the unit directly against a ceiling or wall. (If the unit is in contact with the ceiling or wall, it can cause vibration.)

• Where sufficient clearance for maintenance and service can be ensured.

[PRECAUTION]

• Install the 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 electric noise.)

• The bellows may not be able to be used in some disctricts, so exercise caution. (Contact your local government office or fire department for details.)

• When discharging exhaust air to a common duct, the Building Standard Law requires the use of fire-proof materials, so attach a 2m copper plate standing duct.

(2)Use suspension bolts for installation. Check whether

the ceiling is strong enough to support the weight of the unit or not. If there is a risk, reinforce the ceiling before installing the unit.

(Installation pitch is mentioned as follow. Refer to it to check for points requiring reinforcing.)

4. PREPARATIONS BEFORE INSTALLATION

(1)Confirm the positional relationship between the unit

and suspension bolts. (Refer to Fig. 1)

Leave space for servicing the unit and include inspection hatches. (Always open a hole on the side of the electric parts box so that the air filters, heat exchange elements and fans can be easily inspected and serviced.)

(2)Make sure the range of the unit’s external static pres-

sure is not exceeded.

(See the fan-strength and static performance characteristic drawings as well as the general catalog for the range of the external static pressure setting.)

(3)Open the installation hole. (Pre-set ceilings)

• Once the installation hole is opened in the ceiling where the unit is to be installed, pass transmission wiring, and remote controller wiring to the unit’s wiring holes. See “8. WIRING EXAMPLE AND HOW TO SET THE REMOTE CONTROLLER”.

• After opening the ceiling hole, make sure ceiling is level if needed. It might be necessary to reinforce the ceiling frame to prevent shaking. Consult an architect or carpenter for details.

(4)Install the suspension bolts.

(Use M10 to M12 suspension bolts.) Use a hole-in-anchor, sunken insert, sunken anchor for existing ceilings, or other part to be procured in the field to reinforce the ceiling to bearing the weight of the unit.
