2.3 I Operation
2.3.1 Switching on the pool circuit
•
Check that there are no tools or other foreign objects in the machine.
•
Check that the access panel to the technical section is closed properly,
•
Set the valves to the following positions: valve fully open; valves
, , and closed.
: pool water inlet valve
: pool by-pass valve
: pool water outlet valve
: pool water inlet adjusting valve (optional)
: pool water outlet adjusting valve (optional)
• An incorrect by-pass setting can cause an operating fault on the heat pump.
•
Check that the hydraulic connections are tightened correctly and that there are no leaks.
•
Check that the appliance is stable.
•
Set the water circulation running.
• Close valve
gradually so that the filter pressure is increased by 150 g (0.150 bar).
• Open valves , and
fully, and then half-open valve (to bleed the air that has built up inside the heat pump
condenser and in the filtration circuit). If valves
and
are not fitted, open valve fully and half-close valve
.
2.3.2 Switching on the air heating circuit
•
Open the filling valve on the hydraulic connection kit; see “1.2.2 Dehumidifier water circuit” to fill the dehumidifier
water circuit at the expansion chamber.
•
If there is a risk of frost, add glycol water (maximum 20%).
•
Using the pressure gauge valve, check the pressure. It should be between 1 and 1.5 bar.
•
Check the air bleed on the automatic bleeds (the bleed plugs must be loose).
•
Pay special attention to the dehumidifier heating water circuit during filling. Once the filling and bleed stage is
complete, the circulating pump should display a power rating of 45 W during operation.
