Close the tap and read the static line
pressure on the pressure gauge. The value
should be less than 145 psi.
●
Close the shut off valve of the water pipe.
Remove the water pressure measuring device
and connect the dispenser to the water supply.
●
Ensure that the water shut off valve connected
to the supply line closes properly.
Measuring the water pressure
●
Static and dynamic pressure can be
checked by using a water pressure
measuring gauge which is available locally.
(Fig. 2)
●
Pressure should be checked under the
most unfavorable conditions, e.g. when all
remaining water consuming locations are
opened (dynamic) and when all are closed
(static).
●
Connect the pressure gauge to the water
pipe with a pressure hose. It is possible to
use the hose which serves for connecting
the dispenser later.
CAUTION: The pressure gauge must be
installed at the outlet of the
water filter
●
Close the water tap located on the pressure
testing device and open the shut off valve
in the water pipe completely.
●
Position the outlet above a container and
open the tap. Read the dynamic pressure
on the pressure gauge. The pressure
should always be over 11.5 psi.
