Model
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.
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 custom-
er to keep the area around the unit clean.
WARNING
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.
CAUTION
08
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.
To prevent exposure to wind, install the unit with its
suction side facing the wall.
Never install the unit at a site where the suction side
may be exposed directly to wind.
To prevent exposure to wind, install a baffle plate on
the air discharge side of the unit.
In heavy snowfall areas, it is very important to select
an installation site where the snow will not affect the
unit. If lateral snowfall is possible, make sure that the
heat exchanger coil is not affected by the snow (if
necessary construct a lateral canopy).
6.1 Selecting a location in cold climates
Refer to "Handling" in section “4 Before installation”
When operating the unit in cold climates, be sure
to follow the instructions described below.
NOTE
①
Construct a large canopy.
②
Construct a pedestal.
Install the unit high enough off the ground to prevent it
from being buried in snow.
In case of strong wind and the wind direction can be
foreseen,refer to the figures below for installation of the
unit(any one is OK):
Turn the air outlet side toward the building's wall, fence
or screen.
Make sure there is enough room to do the installation.
Set the outlet side at a right angle to the direction of the
wind.
Prepare a water drainage channel around the
foundation, to drain waste water from around the unit.
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).
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.
When installing the unit in a place frequently exposed
to snow, pay special attention to elevate the founda-
tion as high as possible.
If you install the unit on a building
frame, please install a waterproof plate
(field supply) (within 150mm of the
underside of the unit) in order to avoid
drain water dripping. (See the picture in
the right).
