UNIT INSTALLATION
5.1 Before installation
Before installation
Be sure to confirm the model name and the serial number of the unit.
Handling
Due to relatively large dimensions and heavy weight, the unit should
only be handled using lifting tools with slings. The slings can be fitted
into foreseen sleeves at the base frame that are made specifically
for this purpose.
CAUTION
■ 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.
■ The unit is top heavy! Prevent the
unit from falling due to improper
inclination during handling.
5.2 Selecting the installation site

■ 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 neighbours.
- 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.
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 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.
7 If you install the unit on a building frame,
please install a waterproof plate (field supply)
(about 100 mm.) on the underside of the
unit in order to avoid drain water dripping.
(See figure).
NOTE
Unit is top heavy!
Try not to install on the building frame.
5.2.1 Selecting a location in cold climates
