5. Pipe installation
The installation must be carried out in accordance with the applicable
standards. The boiler must be connected to an expansion vessel in an open
or closed system. Do not forget to flush the heating circuit clean before
connection.
5.1 Pipe connection
• We recommend that the heat pump is connected with a pipeline of at
least Ø28 mm copper pipe, but pressure differential calculations must
be carried out to determine the pipe diameter.
• Route the pipes between the heat pump and the boiler without any
highest points. If this cannot be done, provide this highest point with an
automatic air separator or an in line aerator.
• Fit the packaged filter ball valve to the return line from the boiler. To
clean the filter ball valve, refer to the chapter titled “Operation and
Maintenance”.
• The connection to the heat pump should be made with a wire-
reinforced diffusion-tight hose for DHW, min 1” diameter (available as
an accessory). A minimum of 1000 mm flexible hose is required to
prevent noise transmission into the property and allow for movement of
the heat pump.
• Pipes installed outside should be insulated with at least 13 mm thick
pipe insulation which is not sensitive to water. Ensure that the insulation
is sealed tightly everywhere and that joints are thoroughly taped or
glued.
• Indoor pipes should be insulated all the way to the boiler with at least
9 mm thick insulation. This is to enable the heap pump to deliver the
highest possible temperature to the boiler or tank without any losses.
• The product can be bled via the bleed valve inside the condenser. Note
Only bleed this valve. Other valves are for the cooling system! If
these are opened, refrigerant may leak out!
