Use pressure reducer V9 on the tank to adjust the water pressure to the user to the
permissible value (2 bar), if appropriate. Turning anti-clockwise reduces the pressure and
turning clockwise increases it. Pressure gauge PI 200 shows the user water pressure.
Important:
Do not forget to re-adjust the pressure on returning to normal use.
The system can only be used for a limited time in emergency mode, i.e. until the capacity of the
filter cartridge is exhausted.
Two filter cartridges should always be kept available as reserve.
Please inform Service immediately when you switch your Pacific-AFT to emergency supply.
