H50/150 Smart – User Manual

The Pressure Relief Valve is used to adjust the unit’s fluid flow/pressure.
NOTE: The valve is factory preset for the most common applications and normally
requires no further adjustment. It is factory preset in order not to exceed 60 Psi
(4.0Bar).
Before adjusting the valve turn the unit off. Locate the circular regulation valve opening on the
rear of the unit.
Turn the threaded stem fully counterclockwise.
If the unit is not connected to the instrument to be cooled install a loop of hose equipped with
a shut-off valve between the supply and return fittings.
Turn the unit on.
Use the pressure gauge to see the regulation valve setting.
Turn the threaded stem valve clockwise. Continue until the gauge indicates 60 psi (4Bar) or the
desired setting.
NOTE: the regulation valve may drip if the threaded stem is backed out too much.
