5.3. Manometer use.
SERIES BP heat pumps are equipped with a manometer that displays refrigerant fluid
pressure in the high pressure circuit.
Typical pressure values are the following:
• Heat pump off or in standby, the indicated pressure is between 14÷16 [bar] ([kg/cm
2
]);
• Heat pump running, the indicated pressure is between 21÷35 [bar] ([kg/cm
2
]).
When defrosting, refrigerant fluid pressure is increased to make refrigerant fluid hotter so
that it heats the plate heat exchanger during circulation to defrost. Defrosting lasts several
minutes.

and pool temperature sensors.
SERIES BP control pumps are equipped with sensors that continuously check
ambient and pool water temperatures. The sensors are located as illustrated in the
following figures.
