NSTALLATION OF THE INDOOR UNIT

Selecting an installation location

The unit is to be wall mounted in an indoor location that meets the
following requirements:
■
The installation location is frost-free.
■
The space around the unit is adequate for servicing. (See
figure 2).
■
The space around the unit allows for sufficient air circulation.
■
There is a provision for condensate drain (only for RKHBX
models with drain pan kit EKHBDP) and pressure relief valve
blow-off.
■
The installation surface is a flat and vertical non-combustible
wall, capable of supporting the operation weight of the unit (see
"Technical specifications" on page 38).
■
There is no danger of fire due to leakage of inflammable gas.
■
All piping lengths and distances have been taken into
consideration.
Requirement
Maximum allowable refrigerant piping length between
outdoor unit and indoor unit
Minimum required refrigerant piping length between
outdoor unit and indoor unit
Maximum allowable height difference between
outdoor unit and indoor unit
Maximum allowable distance between the 3-way
valve and the indoor unit (only for installations with
domestic hot water tank).
Maximum allowable distance between the domestic
hot water tank and the indoor unit (only for
installations with domestic hot water tank). The
thermistor cable supplied with the domestic hot water
tank is 12 m in length.
■
During normal operation the hydrobox unit will produce sound
which could be observed as noise. The sound origin can be
water pump operation and/or contactor activation. Therefore it is
advisable to install the hydrobox unit on a firm wall and not in nor
close to a sound sensitive environment (e.g. bedroom).
■
Do not install the unit in places with high humidity (e.g.
bathroom).
■
Select piping diameter in relation to required water flow and
available ESP of pump.
■
The equipment is not intended for use in a potentially explosive
atmosphere.
■
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.
■
Take care that in the event of a water leak, water can not cause
any damage to the installation space and surroundings.
■
Do not place any objects or equipment 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.
CAUTION
If the installation is equipped with a domestic hot water
tank (optional), please refer to the domestic hot water tank
installation manual.
