6 SELECTING THE INSTALLATION SITE
WARNING
■ Be sure to provide for adequate measures in order to prevent
that the unit be used as a shelter by small animals.
■ Small animals making contact with electrical parts can cause
malfunctions, smoke or fire. Please instruct the customer to keep
the area around the unit clean.
1 Select an installation site where the following conditions
are satisfied and one that meets with your customer's approval.
- Places that are well-ventilated.
- Places where the unit does not disturb next-door neighbors.
- Safe places which can bear the unit's weight and vibration
and where the unit can be installed at an even level.
- Places where there is no possibility of flammable gas or product
leak.
- The equipment is not intended for use in a potentially explosive
atmosphere.
- Places where servicing space can be well ensured.
- Places where the units' piping and wiring lengths come within the
allowable ranges.
- Places where water leaking from the unit cannot cause damage
to the location (e.g. in case of a blocked drain pipe).
- Places where rain can be avoided as much as possible.
- Do not install the unit in places often used as a work space.
In case of construction work (e.g. grinding etc.) where a lot of dust
is created, the unit must be covered.
- Do not place any objects or equipment on top of the unit (top
plate)
- Do not climb, sit or stand on top of the unit.
- Be sure that sufficient precautions are taken in case of refrigerant
leakage according to relevant local laws and regulations.
2 When installing the unit in a place exposed to strong wind, pay
special attention to the following.
Strong winds of 5 m/sec or more blowing against the unit's air
outlet causes a short circuit (suction of discharge air), and this
may have the following consequences:
- Deterioration of the operational capacity.
- Frequent frost acceleration in heating operation.
- Disruption of operation due to rise of high pressure.
- When a strong wind blows continuously on the front of the unit,
the fan can start rotating very fast until it breaks.
In normal condition,refer to the figures below for installation of the
unit:
In case of strong wind and the wind direction can be foreseen,refer
to the figures below for installation of the unit(any one is OK):
■ Turn the air outlet side toward the building's wall, fence or screen.
Make sure there is enough room to do the installation
■ Set the outlet side at a right angle to the direction of the wind.
Strong wind
Blown air
3 Prepare a water drainage channel around the foundation, to drain
waste water from around the unit.
4 If water does not easily drain from the unit, mount the unit on a
foundation of concrete blocks, etc. (the height of the foundation
should be about 100 mm (3.93 in).
5 If you install the unit on a frame, please install a waterproof plate
(about 100 mm) on the underside of the unit to prevent water from
coming in from the low side.
6 When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation as high as possible.
