Sanitary Water Tank
Safety relief valve
This Air-to-Water Hydro Tank have two safety
valves, one for the (TANK) in indoor unit and one for the
(CIRCUIT) in outdoor unit.
•
The TANK’s safety relief valve sometimes releases a
little water after hot water usage. This is because the
cold water, which enters the water heater, expands when
heated, causing the pressure to rise and the safety valve
to open.
•
The CIRCUIT’s safety relief valve must be completely
closed and must not normally release any water.
