WATER LOOP AND DRAINAGE PIPE CONNECTION

PLEASE PAY ATTENTION TO THE BELOW POINTS WHEN CONNECTING THE
WATER LOOP PIPE.
Make sure to close the main water supply.
Make sure the water pipe is internally completely clean, and the water loop is
smooth with no obstructions.
Install the water pipes and accessories (not included). Refer to the pipeline
connection sketch (see illustration 1 and 2).
A one-way safety valve must be installed (see illustration 1). The one-way
safety valve will prevent water from flowing back to the water grid. This safety
valve also has an important safety function; it is also a pressure relief valve
which (when correct installed) will prevent that the pressure in the boiler can
become too high. If not installed, it could cause damage to the heat pump
boiler, or even cause injuries. The set point of this safety valve is 0.7 MPa. For
installation position refer to the pipeline connection sketch (see illustration 1).
• The water drain pipe from one way safety valve to sewer is to be installed
in a continuously downward direction and in a frost-free environment.
• The water should drip from the discharge pipe of the one-way safety
valve. Therefore this pipe must be left open to the atmosphere.
A Y-shaped filter (not included) should be placed in the water inlet (see
illustration 1).
Always run the condensing water drain hose/pipe downward all the way. Do
not block the water flow by a rise, and do not put the end of the condensing
water drain hose/pipe into water.
