How to Install Mobile Griff

Before the unit is connected to the water supply pipe, the supply line should be rinsed carefully in order to remove coarse impurities and metal shavings.
The connection for water must be made at the right side of the unit. (for additional details regarding the requirements to the water supply pipe see drawing 110003704, 110003703).
Minimum internal diameter of the supply pipe must be at least 1/2” external.
The supply pipe must be fitted with a closing valve for water on the inlet (see drawing 110003704, 110003703).

The pressure loss in the supply line must be held as low as possible by:

• avoiding long supply pipes
• mounting low pressure resistance ball valves and
• avoiding fittings with high pressure loss.

When installing the piping, take care to avoid air traps.

All pipe connections to the unit must be screwed connections ensuring simple maintenance and dismantling of the station.

Max. allowed temperature of supply water: 70°C (158F)
Max. allowed pressure of supply water: 40 bar (580 psi)
Water consumption at rinsing mode: 30 l/min (7.9 gpm).

• For an optimum functioning of the injector system, we recommend installing a filter on the inlet to avoid impurities.

Always make sure sufficient water supply is available:

• Boosters and mainstations require a 2 bar (30 psi) dynamic inlet pressure. Not 2 bar (30 psi) against a closed ball valve, but 2 bar (30 psi) when the unit(s) is in operation and using water.
• The water volume available shall correspond to the number of simultaneous users +10%.

Example

A customer wants a system for 6 simultaneous users, and they shall therefore supply mini­mum;

• 2 bar (30 psi) dynamic inlet pressure
• 6x 8 gpm = 181 l/min (48 gpm) + 10% = 196 l/min (52 gpm)
