NSTALLATION OF THE UNIT
6.1. Selecting an installation location
WARNING
■
Make sure to provide for adequate measures in order
to prevent that the indoor unit should 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.
The unit is to be placed in an indoor location that meets the following
requirements:
General
■
Installation shall be done by a licensed technician, the choice of
materials and installations shall comply with local and national
regulations.
■
The equipment is not intended for use in a potentially explosive
environment.
■
There is no danger of fire due to leakage of inflammable gas.
■
If the sound is measured under actual installation conditions, the
measured value will be higher than the sound pressure level
mentioned in the
"Unit specifications" on page 27
environmental noise and sound reflections. Choose the
installation location carefully and do not install in a sound
sensitive environment (e.g. living room, bedroom, ...).
■
Be sure that sufficient precautions are taken, in accordance with
relevant local and national regulations, in case of refrigerant
leakage.
Location requirements
■
The installation location is frost-free and indoors.
■
Take care that in the event of a water leak, water can not cause
any damage to the installation space and surroundings.
■
The foundation must be strong enough to support the weight of
both models.
The floor is flat to prevent vibrations and noise generation and to
have sufficient stability especially when the optional domestic
hot water tank is mounted on top of the unit.
■
Volume of installation location
During operation the heat pump module increases the domestic
water temperature by using the indoor stored heat. Typical
installation location for this product is a garage, cellar, technical
room, etc.
To have an optimum unit operation and to prevent a too big
temperature drop in the installation location, take the following
requirements for the installation location into account:

■ Minimum volume of the installation room
The heatpump operation stops whenever the indoor ambient
temperature becomes lower than 2°C (this can be adapted
by field setting [7-04]). After that, the electric heater in the
domestic hot water tank module will continue to heat up the
domestic hot water. This is a unit safety that prevents the
installation room to cool down further (preventing that e.g.
water piping in the installation room gets damaged) and
guarantees a sufficient comfort level in the form of sufficient
amount of domestic hot water.
To prevent this safety to occur frequently and to assure the
use of the electric heater as little as possible, the room size
must have a minimum volume (see figure below). All
depends on the outdoor temperature, the temperature
setpoint of the adjacent heated room and the insulation
properties of the walls. The volumes in the figure are valid for
an outdoor temperature of –10°C and a temperature setpoint
of the adjacent heated room of 16°C.
With this room volume, the heatpump can heat up 260 liters
domestic hot water from 10°C to 60°C.
due to
When the installation room size does not match the minimum
requirement volume or if the walls between the installation
room and adjacent heated room have better insulation
properties than a single brick wall, additional heat sources
must be considered.
Examples of heat sources:
- if installed in a basement the ground surrounding the
basement will heat up the installation room temperature
- if installed in a garage, the heat of the cars engine
- natural ventilation via e.g. doors leading to the adjacent
heated rooms
- ventilation connection to a heated room
- other: washing machine, dryer
