Note:
The cable used for priority heating and the electrical power supply cable must be strapped together inside the unit until just
after the cable packing gland.
COMMISSIONING
Preliminary inspections
• check that the hydraulic connections are tight.
• check that the unit is stable
(as well as level and upright)
.
• check that all cables are secure and all terminal connections are correct.
• check that the electrical supply and priority heating cables are not exposed to sharp or hot elements which could
damage them, both inside and outside the unit.
• check that the unit is connected to earth
(Green/Yellow conductor)
.
• ensure not tools or other objects have been left inside the unit.
• ensure the side panel providing access to the technical section is in place.
Commissioning step-by-step
Recommendations to attain the required temperature:
Protect the pool with a cover (blister cover, roller cover …).
Heating a pool without a cover is like heating a house with the windows open!
Switch the filter system to «Manual» mode, 24/24 (unless priority heating is connected).
Take advantage of periods when the outside temperature is mild (> on average 10 °C) in order to facilitate the temperature
increase. The task of the heat pump is to extract the heat from the surrounding air and transfer it to the pool water. The higher the
air temperature, the more heat the heat pump will be able to transfer to the pool water.
Remark:
before beginning commissioning step-by-step, note the position of each of the valves V1, V2, V3, V4 and V5, in the
hydraulic circuit of the pool (see chapter «CONNECTIONS » paragraph «Hydraulics»).
-1-
To begin with, the by-pass and regulator valves are placed as follows:
- Valve V1 completely open.
- Valves V2-V3-V4-V5 closed.
Note:
in the aforementioned configuration, the heat pump is not yet supplied with pool water.
-2-
Switch on the filter system.
-3-
Progressively close valve V1 in order to increase the filter pressure to
150
g (
0.150
bar).
-4-
Open valves V2, V3 and V4 completely, then half open valve V5 (the air accumulated in the heat pump condenser
unit and in the filter circuit is then evacuated).
?
If valves
V4 and V5
are
not present
,
open
valve
V2
completely
and
half close valve
V3
.
-5-
Switch on the electrical supply to the heat pump.
?
When the regulator is first switched on, the following information messages appear:
REXX then MAPX
.
-6-
If the heat pump is in stand-by (red dot between the first 2 digits
), press and hold for
3 s
the key
,
appears for
5 s
and then the water temperature is displayed.
-7-
Set the temperature to the value required* (keys
+
or
+
) =>. If the pool requires heating,
the indicator
blinks for 2 to 3 minutes then remains on and the heat pump comp fan start up at the same time.
* also referred to as target point, this value is limited to 32°C in order to protect the pool liner. However, this max. limit may be adjusted by
the installer with the assistance of the P.S.A. after-sales service dept. but the installer remains responsible for this modification.
?
During the first 5 minutes of compressor and fan operation, the 3 coloured bars located left of the display
blink
, then only one bar remains on. This indicates whether the water flow-rate through the heat pump is: too low
(bottom «red» bar)
correct
(middle «green» bar)
or too high
(top «red» bar)
-8-
If the regulator detects that the flow-rate is too low or too high, valve V5 (or V3 if V5 is not present) must be
adjusted until the «green» middle bar lights up.
Attention !
During this adjustment phase, wait 30 s after each valve position
change as the regulator response time is not instantaneous.
Incorrectly tightened terminals may cause overheating of the electrical terminal rail.
