Installation guidelines

Keep in mind the following guidelines when installing the domestic
hot water tank:
The installation location is frost-free.
Make sure to make the piping in size 1" or more (and reduce to
3/4" at the inlet of the tank) as to have sufficient water volume in
the piping between unit and domestic hot water tank.
Locate the domestic hot water tank in a suitable position to
facilitate ease of maintenance; remember access is required to
the electrical box. Refer to the grey-coloured zones indicated in
figure 2.
Provide a connection for the pressure relief valve blow-off and
drain.
To avoid back siphonage it is advised to install a non-return
valve on the water inlet of the domestic hot water tank in
accordance with local laws and regulations.
Take care that in the event of a leak, water can not cause any
damage to the installation space and surroundings.
