362 Tank press. min Stop
Tank2 press.min Stop Level in tank is below the
minimum. Level in the tank is too
low, level sensor dirty,
defective Fill tank, check the
function of the tank
sensor
373 Press CW-EV max stop Liquid pressure in the inlet
is too high Evaporator dirty, water
quantity too high Clean the evaporator,
adjust the water
quantity, check the
water quality
374 Press CW-EV minstart Liquid pressure at the
evaporator too low after
switching on. External gate valve closed,
Filter dirty,
Air in the system. Open external gate
valve, clean filter, vent
the system.
375 Press CW-EV min run Cold water pressure at the
evaporator too low during
operation. External gate valve closed,
Filter dirty,
Air in the system. Open external gate
valve, clean filter, vent
the system.
