Frequency of Refrigerant Leakage Checks
For unit that contains fluorinated greenhouse gases in quantities of 5 tonnes of CO
more,but of less than 50 tonnes of CO
detection system is installed, at least every 24 months.
For unit that contains fluorinated greenhouse gases in quantities of 50 tonnes of CO
more, but of less than 500 tonnes of CO
detection system is installed, at least every 12 months.
For unit that contains fluorinated greenhouse gases in quantities of 500 tonnes of CO
more,at least every three months, or where a leakage detection system is installed,at least every six
months.
This air-conditioning unit is a hermetically sealed equipment that contains fluorinated greenhouse gases.
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 conditions
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 vibra-
tion 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).

WARNING
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.
