12. Installation
12.1 Installation Preparation
Warning: The accessories needed for installation must be retained in your custody until the installation work
is completed. Do not discard them.
1)
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.
2)
Hold the unit by the hanger brackets when opening the crate and moving it, and do not lift it holding on
to any other part (especially the duct connecting flange).
Note: 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.
12.2 Select the Installation Site
1)
Select an installation site where the following conditions are fulfilled and meet with your customer's
approval.
a.
HRV should be installed far away from office, recreation or any other place silent requiring environment
(install that in special machine room or wash room is recommended)
b.
install in a place which has sufficient strength and stability. (Beam, 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.
c.
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.)
d.
Where sufficient clearance for maintenance and service can be ensured.
Caution:
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 districts, 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)
Do not install the unit in the following locations:
Place subjected to high temperature or direct flame. May result in fire or overheating.
●
Place such as machinery plant and chemical plate where gas, which contains noxious gas or corrosive
●
components of materials such as acid, alkali organic solvent and plaint, is generated. Place where
combustible gas leakage is likely.
Copper piping and brazed joins may corrode, causing refrigerant to leak or poisoning and fore due to
leaked gas.
Place such as bathroom subjected to moisture.
●
Electric leak or electric shocks and other failure can be caused.
Near machinery emitting electromagnetic waves.
●
Electromagnetic waves may disturb the operation of the control system and result in a malfunction of the
equipment.
