ERSQ+ERRQ011~Y1
Outdoor unit for air to water heat pump
4PW49635-1A
■
Do not install the unit in places such as the following:
■
Where there is mist of mineral oil, oil spray or vapour for
example a kitchen.
Plastic parts may deteriorate, and cause them to fall out or
water to leak.
■
Where corrosive gas, such as sulphurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may cause the
refrigerant to leak.
■
Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system, and
cause malfunction of the equipment.
■
Where flammable gases may leak, where carbon fiber or
ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
Such gases may cause a fire.
■
Where the air contains high levels of salt such as that near
the ocean.
■
Where voltage fluctuates a lot, such as that in factories.
■
In vehicles or vessels.
■
Where acidic or alkaline vapour is present.
■
Do not allow a child to mount on the outdoor unit or avoid
placing any object on the unit.
Falling or tumbling may result in injury.
■
Do not touch any refrigerant which has leaked out of refrigerant
piping connections.
This may result in frostbite.

NSTALLATION OF THE UNIT
4.1. Selecting installation location
1 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.
2 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.
- 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.
■
Turn the air outlet side toward the building's wall, fence or
screen.
■
Set the outlet side at a right angle to the direction of the wind.
3 Prepare a water drainage channel around the foundation, to
drain waste water from around the unit (field supply).
4 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).
5 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.
6 When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation as high as
possible.
7 The outdoor unit may short circuit depending on its environment,
so use the louvers (field supply).
8 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) or use a drain kit (refer to
combination table in
"General information"
on page 1 ) in order to avoid the drainwater
dripping. (See figure).
■
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.
