TECHNICAL MANUAL. START-UP AND OPERATION
Before any start-up, you should check:
 The correct clamping of the hydraulic connections (exchanger inlet / outlet).
 The correct fastening of the electrical cables to the connection terminals. Poorly secured terminals can cause the
terminal block to heat up.
 There are no hydraulic leaks on the exchanger connectors.
 The insulation of electrical cables from any kind of plate or metallic piece that may damage it.
 The earth connection of the heat pump.
 The stability of the machine and its level (for the disposal of the condensed material).
 There are no tools or foreign objects inside the machine.
Performing the heat pump adjustments in its initial operation
1. Start filtering in order to circulate the swimming pool water inside the heat pump exchanger. It is essential that the filtering equip-
ment starts before the heat pump.
2. Switch the heat pump on. Turn on the magnetic circuit breaker.
3. Set the temperature you prefer (5.E. Description and operation of the controller).
4. The installing technician must adjust the valves of the by-pass according to the pressures of the machine and must refrain from
intervening anymore during the warming-up period.
The heat pump should always operate together with the purification pump. We must have the precaution never
to interconnect timers or programmers which may stop the purification pump and leave the unit working
The heat pump will take several days to reach the requested temperature: this is completely normal.

7. HIBERNATION PROCEDURE

 Switch off the filtering pump.
 Turn off valves 2 and 3 of the by-pass.
 Open completely valve 1.
 Drain the exchanger to protect it from ice, disassembling the inlet and outlet connectors of the heat pump.
 Once drained part of the condenser, assemble the connectors.
 Check the connectors of the heat pump to restrict the entrance of foreign bodies to the exchanger.

8. GUARANTEES

There is a 2-year warranty for all the parts.
All the elements made in TITANIUM in contact with the swimmingpool water are guaranteed 15 years against rusting.
In the event of warranty cancellation:
 A failure or a mistake in the hibernation procedure leads to the cancellation of the warranty.
The elimination, suppression or modification of one of the safety components involves the cancellation of the warranty.
 A failure in the installation procedure which is related to the lack of observance of the instructions contained in this
manual will mean the cancellation of the warranty.
The warranty will only have effect if the coupon is returned duly completed, sealed and signed by all
