• The pressure relief valve is set and sealed at the
-
tomer service.
6.11.2 Thermal valve
• The thermal valve protects the high-pressure pump
against non-permitted heating in circuit operation
• The thermal valve opens when the water temper-
ature exceeds 55 - 60°C and discharges the hot
water to the outside.
