INSTALLATION
CHOICE OF THE INSTALLATION LOCATION:
Wherever possible, the heat pump should be installed close to the existing hot-water conduit.
The location must be indoors in a frost-free environment with a frost protected sewer drain. The floor at the location must be
flat and at level. Minor irregularities can be levelled by means of the adjustable feet. It has to support the weight of the DHW
HP (approx. 430 kg filled). The location must be designed to support the corresponding load. If the HP will operate mostly
on off peak hours do not install the product near to bedrooms. Even if the DHW HP operates very silently, this might
disturb sensible users. Please ensure that the location and the DHW HP are easily accessible for maintenance and service.
All damages and service impossibilities (e.g. repair), due to the reduced accessibility are part of the installer/user
responsibility and not covered by the manufacturer's warranty.
NOTE: State-of-the-art building regulations, standards and legal requirements must be observed.
Unused connectors (Coil, recycling loop) have to be sealed and insulated properly in order to avoid heat losses.
The DHW HP works either with ambient air or outside air. Independent of the installation mode there are some basic
requirements for the air quality of the airflow:
- The air must be dust and grease free
- The air source should benefit from free energy gains like in the laundry (dryer waste energy), kitchen,
garage (appliances and car waste energy), basement (geothermal energy) and heating cabinet.
- The air temperature must be > -10°C
- The air source can benefit from dehumidification
- The exhaust air is cooled down and can be used for cooling e.g. a wine cellar
The easiest way to install the DHW HP is the ambient air installation:
In the ambient air mode the product doesn't need ducting. The air inlet uses the ambient air of the location and the air outlet
exhausts the air into the same room. This installation mode needs some requirements:
- Room volume > 20 m
- Free air flow, no air re-circulation (air short-circuit between inlet and outlet
- Ventilation of the location (air inflow > 200 m
- Location must not be heated by a heating system
In this installation mode the fan speed should be adjusted at "high". Anyhow, if you should want to change the fan speed for
comfort reasons to "low", you can do so without a considerable decrease of performance.
Semi ducting or full ducting can increase the efficiency. In this way you can optimise the airflow and the efficiency.
- Semi ducting is usually used for the exhaust side to avoid mixing ambient and exhausts air.
- Semi ducting helps to reduce the noise level
Full ducting on air inlet and air outlet gives the possibility to position air inlet and outlet independent of the DHW HP
location. Full ducting is also recommended for the use of exterior air.
In this installation mode the fan speed should be adjusted at "high".
It is also possible to use the DHW HP ducted with extracted air. For this special application the minimum air flow
requirements of the HP have to be matched with the airflow design of the ventilation.
The fan speed for permanent operation can be selected separately.
For more details see "air connections – ducting"
PREPARATION FOR INSTALLATION:
The heat pump is delivered adjusted and ready assembled with wire and plug. Just connect the water inlet and outlet to the
piping. The defrost water from the evaporator is evacuated by a drain (13) and has to be connected to the sewer. The
dimensions of the DHW HP and the connections see "design & dimensions".
General rules for hydraulic connection:
Your DHW HP has a high quality steel tank for the DHW generation. This tank inside is enamelled and gives you a perfect
protection against corrosion in combination with an additional catholic protection (magnesium anode). Nevertheless, in
order to protect the tank and also the connectors you have to avoid connecting copper pipes to steel or galvanized steel
fittings directly (in flow direction). The use of insulation fittings is mandatory in this case.
NOTE: The installation must be done according to the state of the art of installation. The non-respect of these rules and
abnormal water composition may be the reason of warranty exclusion. The manufacturer has no liability for the installation
and possible damages to it.
