Check and set pressure limiting valve
Deadly risk!
Working on open, live equipment!
• Do not operate the equipment with damp hands!
• Caution: live components!
Setpoint value opening pressure = 5.5 bar
Accomplish settings at operating temperature (warm equipment) only!
Risk of damage!
Dryer and humidity shut-off work reliably only, if the pressure limiting valve (38) is set properly.
Check opening pressure
Deadly risk!
Switch off operating voltage!
Risk of injury!
Prior to operation, depressurise the equipment by opening the safety valve "high pressure" (29)!
Risk of injury!
Wear protective goggles when opening safety valve „high pressure” (29)!
• Unscrew blind cover (
78
) from the pressure limiting
valve (
38
).
• Unfasten hose connection from the manometer "high pres-
sure" (
17
):
- unscrew connecting nut.
- pull out hose.
• Connect the supplied testing hose (
80
) to the pressure lim-
iting valve (
38
) and the manometer "high pressure" (
17
)
(
so the manometer "high pressure" (
17
) can be used as a
test gauge
).
• Close safety valve "high pressure" (
29
).
• Switch on operating voltage
- The manometer "high pressure" (
17
) must increase
by 5.5 ±0.1 bar.
38 78
otherwise:
Set setpoint value opening pressure of pressure limiting valve
• Pull setting knob (
38
) back and turn until the manometer "high pressure" (
17
) displays the setpoint value.
• Press on the setting knob (
38
) again and allow it to lock into place.
Restore operating status
• Switch off operating voltage!
• Depressurise the equipment by opening the safety valve
"high pressure" (
29
)!
• Remove testing hose (
80
).
• Insert hose on manometer "high pressure" (
17
) again and
screw in tightly.
• Screw on blind cover (
78
) on the pressure limiting valve
(
38
).
• Close safety valve "high pressure" (
29
).
29
• Switch on operating voltage again
• Check all threaded hose coupling for impermeability.
