Only certificated person is allowed to do installation, operation and maintenance.

6 INSTALLATION SITE

There is flammable refrigerant in the unit and it should be installed in a well-ventilated site. If the unit is installed
inside, an additional refrigerant detection device and ventilation equipment must be added in accordance with the
standard EN378. Be sure to adopt adequate measures to prevent the unit from being used as a shelter by small
animals.
Small animals making contact with electrical parts can cause malfunction, smoke or fire. Please instruct the
customer to keep the area around the unit clean.
Select an installation site where the following condtions are
satisfied and one that meets with your customer's approval.
Places that are well-ventilated.
Places where the unit does not disturb 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 object 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.
Don't install the unit near the sea or where there is
corrosion gas.
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.
