2.1 I Selecting the location
• The appliance must be installed in a dry ventilated plant room with no pool maintenance
products stored nearby.
• The appliance must be installed before any water treatment system.
• The water inlet of this appliance shall not be connected to inlet water obtained from any other
water heating system.
• The appliance must be positioned vertically and held by piping supported by brackets on either side of the
heater,
• The appliance must be secured to the wall using 4 screws (not provided, see attachment points in the
rear view § "1.3 I Dimensions and marking"),
IMPORTANT: Do not attach the appliance using adhesive tape.
• Leave a free space around the appliance to facilitate its installation and maintenance,
• Preferably, the appliance should be installed at the low point so that it is always full of water,
• The water treatment system must be installed at the low point after the heater to prevent chlorine from
flowing back into the heater.
2.2 I Hydraulic connections
• The appliance
water treatment system
• The connection can be made using a PVC pressure pipe:
- directly if the water flow falls within the range 5 m
- via a by-pass if the flow rate is greater than 22 m³/h, or for easier maintenance of the appliance,
• 1/2 union fittings (Ø50 internal female coupling and Ø63 external male coupling) are provided for
connection to the filtration circuit with Ø50 or Ø63 PVC piping.
IMPORTANT: Do not re-use worn couplings and do not connect the outlet pipe to any tap or fitting other
than those specified.
• Check the correct clamping of the hydraulic connectors and that there are no leaks.
Information: filtration circuit with Ø63 PVC piping
• To connect the appliance, provide an adapter (internal Ø of 63).
Information: direction of flow
• The heater is provided for a water flow circulating from left to right as shown by the "water
inlet" and "water outlet" symbols visible on the appliance.
• If necessary, reverse the direction of flow as follows:
- invert the digital regulation thermostat and safety thermostat sensors. The regulation
thermostat must be located at the heater inlet and the safety sensor at the outlet.
- rotate the 2 bends + flow switch together by half a turn (see diagram below).
