EKMBUHBA6V3
Heater kit for air to water heat pump system
4PW63549-1A – 08.2010
5.2. Safety devices
■ Thermal protector — The heater in the heater kit is equipped
with a thermal protector. The thermal protector is activated when
the temperature becomes too high. When activated, the
protector has to be reset on the heater of the heater kit by
pressing the red button (for access, remove the cover of the kit).
■ Pressure relief valve — In case valves are installed between the
outdoor unit and the heater kit and between the outlet and the
load, a pressure relief valve (field supply) in accordance with
relevant local laws and regulations, and with an opening
pressure of maximum 4 bar must be installed on the water inlet
of the heater kit.
6. INSTALLATION OF THE HEATER KIT
6.1. Selecting an installation location
The heater kit is to be wall mounted in an indoor location that meets
the following requirements:
■ The installation location is frost-free.
■ The space around the heater kit is adequate for servicing. (See
figure 3).
■ The space around the heater kit allows for sufficient air
circulation.
■ The installation surface is a flat and vertical non-combustible
wall, capable of supporting the operation weight of the heater kit.
■ There is no danger of fire due to leakage of inflammable gas.
■ All piping lengths and distances have been taken into
consideration.
■ During normal operation the heater kit will produce sound which
could be observed as noise. The sound origin can be contactor
activation. Therefore it is advisable to install the heater kit on a
firm wall and not in nor close to a sound sensitive environment
(e.g. bedroom).
■ Do not install the heater kit in places with high humidity (e.g.
bathroom).
■ The equipment is not intended for use in a potentially explosive
atmosphere.
■ Do not install the heater kit in places often used as work place.
In case of construction works (e.g. grinding works) where a lot of
dust is created, the heater kit 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 heater kit.
■ Make sure that there are no external magnetic fields in the
immediate vicinity of the flow switch, since these can impair
device functioning.
6.2. Dimensions and service space
Unit of measurement: mm.
Dimensions of the heater kit, see figure 2.
Required service space, see figure 3.
CAUTION
The heater kit air purge connection may not be used for
other purposes.
CAUTION
■ The electrical box lid must only be opened by a
licensed electrician.
■ Switch off the power supply before opening the
electrical box lid.
CAUTION
■ The heater kit can only be installed and used in
combination with the EBHQ outdoor unit and EKCB
indoor unit.
■ The heater of the heater kit can only be connected to
the space heating water outlet of the EBHQ outdoor
unit. Other connections are not allowed.
■ Only one heater kit can be connected to the EBHQ
outdoor unit. It is not allowed to combine multiple
heater kits in series or parallel.
Requirement Value
Maximum allowable distance between the heater kit
and the outdoor unit.
10 m
