* Heat pump operating conditions:
• The outside temperature must be higher than -8°C
(automatic shut-off by anti-frost sensor SD2)
and below +38°C.
• A sufficient water flow must pass into the heat pump.
Note:
The heat pump stops heating the pool water when it starts a defrost cycle by inverting the cycle
.
A defrost cycle is started (Led «defrost cycle»
on)
when the defrost sensor SD3
(located in the cooling circuit)
detects a
temperature of less than
-5°C and
a minimum time between two defrost cycles has been attained or when the regulator is
switched on. If the time between cycles has not been attained (with SD3 < -5°C) the Led «defrost cycle» is
blinking
.
- Reminder:
during the defrost cycle a steam cloud
(water vapour)
may appear from the back of the unit
(after a defrost cycle,
when the fan(s) are restarted. This cloud is evacuated to the back of the unit)
.
- This unit is equipped with a titanium heater condenser/unit heater anti-frost system
controlled by an anti-frost sensor
(SD2)
connected to a regulator
(rA displayed during operation)
.
ATTENTION !
This titanium condenser/unit cooler
anti-frost safety device
is
only functional
when the unit’s electrical power supply remains switched on
(tjs regulator on or in stand-by).
6.1 Check
•
that the hydraulic connections are correctly tightened.
• that there is no water leak.
• that the appliance is stable (with a level gauge and spirit level).
• that the cables are correctly connected to their terminals.
Incorrectly tightened cables may cause overheating of
terminals
.
• that the cables cannot be damaged by sharp metal sheets or elements.
• the earth connection.
• that no tools or other objects have been left inside the appliance.
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 (
+
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.
