EQUIPMENT APPLICATION AND OPERATION

6.1

OPERATING INSTRUCTIONS

IMPORTANT:
In order the heat pump to heat the pool the fi ltration pump has to operate and water must fl ow through the heat exchanger.
Never switch the heat pump on if dry and the fi ltration system is not operating
Never cover the heat pump, as fresh ambient air must fl ow through it.
Protect the heat pump from frost. Before winter season drain all water from the fi ltration system and the heat pump and store them
for winter according to relevant instructions.

ADJUSTMENT OF OPERATING STATE USING BYPASS

In case a bypass line comprises a part of fi ltration circuit (it is not delivered as a part of heat pump supply), it may be used for setting the optimum operation
of heat pump after putting the latter in operation.
Bypass Use
The bypass line consists of three cock valves installed according to the fi gure below. On the right water comes from the fi ltration pump, while on the left it
fl ows through the return line back to the pool.
Close the cock valve 1 completely and open the cock VALVES 2 AND 3 on the inlet and outlet lines of the heat pump, respectively. At these conditions there is the maximum fl ow through
the heat pump. Put the heat pump into operation in the heating mode. Wait until the value of pressure read on the pressure gauge stabilizes. The correct pressure setting should be
within the range of 21 - 35 kg/cm
rate through the heat pump. If the pressure stabilizes above the value of 35 kg/cm
Routine adjustments of the three bypass valves:
COCK VALVE 1: Closed a bit so that the heat pump pressure gauge shows a pressure within the range from 21 to 35 kg/cm
COCK VALVE 2: Open.
COCK VALVE 3: Half closed.
