animals making contact with electrical parts can cause malfunction, smoke or fire. Please instruct the customer to
keep the area around the unit clean.
WARNING
Frequency of Refrigerant Leakage Checks
- Equipment that contains less than 3 kg of fluorinated greenhouse gases or hermetically sealed equipment,
which is labelled accordingly and contains less than 6 kg of fluorinated greenhouse gases shall not be
subject to leak 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.
- 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.
CAUTION
Select an installation site where the following condition sare 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.
- Motor burnout.
