T&P Temperature and pressure relief valve
1. For boiler water supply temperatures over 203° F (95° C):
Remove plastic supply and return grommets
(grommets are left-threaded).
2. Pipe supply line with an incline and install an air vent
valve at the highest point.
3. For boiler water supply temperatures over 230° F
(110° C):
Install a type-tested high limit safety cut-out, if no other
has previously been installed in this system. For this
purpose, install a dual thermostat (high limit thermostat
and high limit safety cut-out).
4. Close off test nipples which are not used for the
installation of a probe or sensor.
Use a Loctite 55 string and pipe dope on all threaded
nipples on tank.
DANGER
Due to the potentially high DHW temperatures generated
by the solar heating system, the domestic hot water
temperature must be limited to a maximum of 140º F (60º C)
by installing a anti-scald tempering valve. The tempering
valve does not completely eliminate the risk of scalding at
the tap. The installation of a mixing tap is recommended.
