INSTALLATION

HYDRAULIC CONNECTIONS WITH WATER PRESSURE REGULATING VALVE
(OPTION)

Mount the by-pass solenoid valve with the optional water pressure regulating valve on Heat pump units.

1. Anti-vibration flexible connection

2. Shut-off valve

3. Water pressure

regulating valve

4. ON/OFF solenoid valve (Bypass)

5. Flow switch

6. Mesh filter

7. Condensate water drain / Evacuation

8. ON/OFF solenoid valve with the

compressor

9. Manometer

10. Evacuation valve

NOTE:

Connect the water pressure regulating valve to the high pressure intake of the unit. The drawing shows the heat pump connections.
Do not install the solenoid valve on cooling only units. When installing a water pressure regulating valve it is mandatory to set a
timer for the flow switch at the compressor start-up during 1 minute to let that valve operate.
