ERLQ006~008BBV39
Outdoor unit for air to water heat pump
4PW68003-1A – 03.2011
■ 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 drainwater
dripping. (See figure).
■ Make sure that the unit is installed level.
5.2. Selecting a location in cold climates
Refer to "3.4. Model identification" on page 4.
■ To prevent exposure to wind, install the outdoor unit with its
suction side facing the wall.
■ Never install the outdoor 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 outdoor unit.
■ In heavy snowfall areas it is very important to select an
installation site where the snow will not affect the unit and set
the outlet side at a right angle to the direction of the wind:
1 Construct a large canopy.
2 Construct a pedestal.
Install the unit high enough off the ground to prevent
burying in snow.
3 Strong wind
4 Discharge air
