6 SELECTING THE INSTALLATION SITE
Make sure there is enough room to do the installation
WARNING
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.
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.
