3 BEFORE INSTALLATION
Before installation
Be sure to confirm the model name and the serial no. of the unit.
Handling
Due to relatively large dimensions and high weight, the handling of
the unit is only to be done by means of lifting tools with slings. These
slings can be fitted into specially for this purpose foreseen sleeves at
the base frame.
● To avoid injury, do not touch the air inlet or aluminium
fins of the unit.
● Do not use the grips in the fan grills to avoid damage.
● Unit is top heavy!
Prevent the unit from falling due to inclination during
handling.

5 SELECTING INSTALLATION SITE
■ Make 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.
Make sure there is enough room to do the installation
CAUTION
WARNING
1 Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.
- Places which are well-ventilated.
- Places where the unit does not bother next-door neighbours.
- Safe places which can withstand the unit's weight and vibration
and where the unit can be installed 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 the rain can be avoided as much as possible.
- Do not install the unit in places often used as workplace.
In case of construction works (e.g. grinding works) 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 accordance with
relevant local laws and regulations, in case of refrigerant leakage.
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 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 face of the unit,
the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where the
wind direction can be foreseen.
■ Turn the air outlet side toward the building's wall, fence or screen.
3 Prepare a water drainage channel around the foundation, to drain
waste water from around the unit.
4 If the water drainage of the unit is not easy, please build up the
unit on a foundation of concrete blocks, etc. (the height of the
foundation should be about 100 mm.
5 If you install the unit on a frame, please install a waterproof plate
about 100 mm. of the underside of the unit in order to prevent the
invasion of water from the lower direction.
6 When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation
as high as possible.
7 If you install the unit on a building frame,
please install a waterproof plate (field supply)
(about 100 mm.) of the underside of the unit)
in order to avoid the drainwater dripping.
(See figure).
■ Set the outlet side at a right angle to the direction of the wind.
