II. WATER PIPE INSTALLATION INSTRUCTIONS
01.
Only use quality copper piping for the final connections to the unit.
02. Con
nect the pipes according to the drawing and insulate all pipes. Plastic flexible hose piping is allowed for the
condensate run off.
03.
Cold Water inlet/ hot water outlet requires a G3/4” fitting.
04.
The safety relief valve comes with the product and must be fitted and piped to the drain network.
05. On
ce all the pipe work is complete and all connections are tight, the filling of the system with cold water can begin.
Open up the cold water inlet isolating valve to begin the process. As the water begins to fill up inside the tank, it is
possible to release the build up of pressure by slowly opening the safety relief valve. Repeat this process until the tank
is full and water begins to flow out of the safety relief valve.
06. The correct cold water intake pressure is between 1.5BAR and 6.5BAR. If the pressure is less than 1.5BAR a pressure
pump may be required for operation. Installing a pressure gauge inline with the cold water inlet will assist the user if
there are pressure issues after the installation.
07. During operation and heat pump cycle, there will be condensation droplets within the heat pump. Always ensure
the condensate pipe is connected to the drainage network.
NOTE
▶
The safety relief valve needs to be pulled every six
months to ensure it works correctly and is not blocked.
▶
Do not hold down the handle of the safety valve.
▶
Do not block the drain.
If this product is installed in an outbuilding or
unheated space, please ensure all pipework including
ducting is insulated well. Failure to do so could result
infrozen pipework and condensation issues.
NOTE
WARNING
▶
Insulate the drainage pipe to avoid freezing in cold
weather..
