ELECTING INSTALLATION SITE
5.1. General
■
The equipment is not intended for use in a potentially explosive
atmosphere.
■
Choose a place solid enough to bear the weight and vibration of
the unit, where the operation noise will not be amplified.
■
Choose a location where the hot air discharged from the unit or
the operation noise will not cause a nuisance to the neighbours
of the user.
■
Avoid places near a bedroom and the like, so that the operation
noise will cause no trouble.
■
There must be sufficient space for carrying the unit into and out
of the site.
■
There must be sufficient space for air passage and no
obstructions around the air inlet and the air outlet.
■
The site must be free from the possibility of flammable gas
leakage in a nearby place.
■
Locate the unit so that the noise and the discharged hot air will
not annoy the neighbours.
■
Install units, power cords and inter-unit cables at least 3 m away
from television and radio sets. This is to prevent interference to
images and sounds.
■
Depending on radio wave conditions, electromagnetic
interference may still occur even if installed more than 3 m away.
■
In coastal areas or other places with salty atmosphere of sulfate
gas, corrosion may shorten the life of the outdoor unit.
■
Since drain flows out of the outdoor unit, do not place anything
under the unit which must be kept away from moisture.
■
Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.
-
Places which are well-ventilated.
- Places where the unit does not bother next-door neighbours.
- Safe places which can withstand the unit's weight and
vibration and where the unit can be installed 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 indoor and outdoor 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 the rain can be avoided as much as possible.
- Do not install the unit in places often used as work place.
In case of construction works (e.g. grinding works) where a
lot of dust is created, the unit must be covered.
- Do not place any objects 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 accordance
with applicable legislation, in case of refrigerant leakage.
■
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 outdoor
unit's air outlet causes 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 face of the
unit, the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.
■
Install a baffle plate on the air suction side of the outdoor unit
and set the outlet side at a right angle to the direction of the
wind:
1 Baffle plate
2 Strong wind
3 Discharge air
■
Prepare a water drainage channel around the foundation, to
drain waste water from around the unit.
■
If the water drainage of the unit is not easy, please build up the
unit on a foundation of concrete blocks, etc. (the height of the
foundation should be maximum 150 mm).
■
If you install the unit on a frame, please install a waterproof plate
within 150 mm of the underside of the unit in order to prevent the
invasion of water from the lower direction.
■
When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation as high as
possible.
■
If you install the unit on a building frame,
please install a waterproof plate (field
supply)(within 150 mm of the underside of
the unit) in order to avoid the drain water
dripping. (See figure).
■
Make sure that the unit is installed level.
WARNING
■
Make sure to provide for adequate measures in order
to prevent that the outdoor unit be used as a shelter
by small animals.
■
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.
NOTICE
Units cannot be installed hanging from ceiling or stacked.
