6.2 Start up the heat pump
• Switch on the heat pump power supply protection device located inside the filter control cabinet.
• Start filtration.
• Set the by-pass and setting valves* as follows:
- Valve
V1
slightly closed to increase the filter pressure from 150 to 200g (0.15 to 0.20 bar).
-
Valve
V2
fully open.
-
Valve
V3
fully open.
-
Valve
V4
fully open.
-
Valve
V5
half closed.
* see paragraph 4.2.
If the valves (V4 & V5) are not present, set valve V2 to fully open and valve V3 to half closed.
• Check that the swimming pool water hydraulic circuit has been vented.
• Start the heat pump if it is in stand-by mode (red dot) by pressing , ON appears on the display for a period of
5 s before displaying the water temperature.
• Set the target temperature (
SET
+
or ) => if the pool should be heated: Led blinks and then remains
on after approx. 2 to 3 minutes max. and the heat pump starts.
?
5 min. after re-start of the heat pump
(fan + compressor), check the water flow pressure gauge display and set valve V3 or
V5 in order to bring the needle into the green zone (beginning of season {cold water}: position at the start of the green zone).
Reminder:
If, when setting the by-pass and setting valves, the flow rate is less than 1.5 m3/h the heat pump will not
function
(the vane flow monitor is triggered and the regulator displays the message AId alternating with the water temperature)
. Adjust the
setting valves : -
V5
-
(if present)
or -
V3
- and -
V1
-.
When the heat pump is running :
-
If the flow rate switch switches on or off for a period longer than or equal to 3 s, a timer of 130 seconds* min. is
activated before the unit starts again.
* For information
this time period may increase during a defrost cycle or if the compressor stop time is less than 180 s.
-In case of a power failure, a timer of 125 seconds starts when the power supply is restored before the unit starts
again.
Observation:
When the water attains the target temperature (Leds and off) the heat pump switches off
automatically.
Reminder:
The 3-phase heat pump is equipped with a phase order control system (
KA1
) used to check that the phase order is correct
at start up (and during operation) and to signal a phase order fault (regulator indicates dCP fault and the green led
KA1
inside the unit is off. The orange led remains on as long as phase L1 is present). In the case of a unit which is
switched off
and isolated
, it is sufficient to invert two phase wires directly on the main supply terminal.
ATTENTION !
this operation must be carried out by a qualified and authorised professional
6.3 Checking
Check that the heat pump stops heating when:
• the target temperature on the digital display thermostat is decreased
.
• filtration is switched off or valve V2
or V4 closed.
Normal position of the pressure
gauge needle when the appliance is
off
(compressor and fan(s) OFF).
Attention ! this position may vary
slightly in the « STOP » zone
depending on water and ambient air
temperatures.
Normal position of the pressure
gauge needle when the
appliance is in operation
(compressor and fan(s) ON).
The position range in the
«CORRECT » zone may vary
depending on water and ambient air
temperatures, or even attain the
«LOW » zone when the water flow
going into the unit is too low.
