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:

Baffle plate
Strong wind
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:

Construct a large canopy.
Construct a pedestal.

Install the unit high enough off the ground to prevent 
burying in snow.

Strong wind
Discharge air
