Soldering unions
When carrying out soldering work, it is
essential to remove a JRGUMAT thermo-
blending valve from the unions as the
thermostat and the seals would otherwise
be damaged.
Hot water temperature
To ensure that your JRGUMAT thermo-
blending valves operate correctly,
the warm water temperature must be at
least 5 K above the desired blended water
temperature. Identical hydraulic condi-
tions are essential at the hot and cold
water feeds. This is ensured by installing
the mixing valves in the water heater
circuit as shown in our installation
drawings.
Repairs
No attempts should be made to repair
JRGUMAT thermoblending valves.
