Potable water piping
The design and installation of the VELUX solar water heating system should be done by qualified individuals. It is important
that good design and installation practice be followed to assure that your system will operate properly. Failure to follow
installation guidelines for your VELUX solar water heating system could cause component failure and possible safety issues.
It is mandatory that all plumbing be done in accordance with all local and state codes or warranty will be void. It Is also
necessary on all domestic plumbing mechanical connections to use both thread tape and pipe dope. The potable water piping
is located on the top of your solar storage tank and marked Hot and Cold.
All VELUX solar water heating systems are provided with an anti-scald mixing valve, and the required fittings and flexible
copper tubing to properly connect the solar system to the domestic potable water piping system. The anti-scald mixing valve,
and all fittings provided must always be installed as shown in the following instructions. It is recommended that the VELUX
hot and cold water connection fittings provided are always used, so the solar hot water storage tank can be easily serviced.
Install a shut-off valve in the cold feed near the solar storage tank to isolate the tank for future service.
