WARNING
● 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.
CAUTION
● Frequency of Refrigerant Leakage Checks
- For unit that contains fluorinated greenhouse gases in quantities of 5 tonnes of CO
2
equivalent or more,but of less
than 50 tonnes of CO
2
equivalent,at least every 12 months, or where a leakage detection system is installed, at
least every 24 months.
- For unit that contains fluorinated greenhouse gases in quantities of 50 tonnes of CO
2
equivalent or more, but of
less than 500 tonnes of CO
2
equivalentat least every six months, or where a leakage detection system is installed,
at least every 12 months.
- For unit that contains fluorinated greenhouse gases in quantities of 500 tonnes of CO
2
equivalent or 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
● 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 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.
In normal condition,refer to the figures below for installation of the unit:
