If water inlet temperature is below 20ºC we recommend to maintain level condensation temperature in (40 a 45ºC)
FUNCTION
The presostatic valve maintain some values of the condensation pressure regulating the water flow which enter
into the condenser.
When the condensation pressure is up, the valve open and water enter. and when pressure is low the valve close.
PRESOSTATIC VALVES
REGULATION PRESOSTATIC VALVES
• Connect a manometer of high pressure (30 bar) near the refrigerating circuit of the unit.
• Turn over the vastage in the head of the valve( right the valve open, left the valve close) regulating the water flow
which enter into the unit.
• You must leave the unit working during 10 minutes and see the indication of the manometer. If the condensation
pressure temperature is aproximately. 45ºC the valve is correctly regulated. If not restart the regulation described
before.
• Install the kit at the outlet water side of the condenser
• Keep in mind the row indicated in the valve.
• Connect the capillary tube of the valve to the plug of high pressure in the pipe of the unit.
