ERHQ011~W1 + ERLQ011~W1
Outdoor unit for air to water heat pump
4PW54249-1
Model
ERLQ units include special equipment (insulation, bottom plate
heater,...) to ensure good operation in areas where low ambient
temperature can occur together with high humidity conditions. In
such conditions the ERHQ models may experience problems with
severe ice build up on the aircooled coil. In case such conditions are
expected, the ERLQ must be installed instead. These models contain
countermeasures (insulation, bottom plate heater,...) to prevent
freeze up.

Handling

ELECTING INSTALLATION SITE
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.
- 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 relevant local and national regulations, in case of
refrigerant leakage.
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 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.
