4.1.3 - INSULATION OF PIPES
• This operation must be done carefully to avoid any risk of condensation.
• The insulation concerns the water return and inlet pipes.
• Use polyethylene sheathing at least 9 mm thick.
• Once connections have been made, check for leaks, install the insulating sleeves supplied with
the unit on the exchanger water inlet and outlet connections and the tubes up to the collector
(see paragraph 4.1.1). The insulating sleeves must avoid condensation.
4.1.4 - PURGING THE AIR HANDLER'S WATER CIRCUIT
• Done by means of a purge screw
located on the water coil's header.
• To have access to the screw, remove
the air handler's cover.
• Then unscrew the drain plug, taking
care to collect the water, if any.
4.2 - CONNECTING THE CONDENSATE DISCHARGE PIPE
(For air handlers which can operate in cooling mode)
• Connect the condensate pipe to a discharge pipe.
• Fix the two pipes using adhesive tape:
- Ø of condensate pipe: 18mm.
CAUTION
• Make sure that the slope is correct for proper
condensate evacuation.
• Check that condensate drainage is correct and
smooth. To do this, use a bottle to pour water into
the condensate recovery tray.
4.3 - ELECTRICAL CONNECTION for basic version
4.3.1 - PRINCIPLE
• The electrical connection conduits must be fixed.
• Class 1 unit.
• The electrical installation must be carried out in compliance with the rules in force (especially NFC 15-100
4.3.2 - DETAIL OF THE CONNECTION
• To have access to the terminal block:
- remove the air handler's cover (see sketch A),
- remove the terminal block access door (see sketch B).
• Then prepare the wires (stripping length: 5 mm) and
connect them to the terminal block (see sketch C).
• Note: The terminals are of the "cage with spring" type.
Follow the indications below to connect them:
- These terminals take the following wires:
- rigid,
- flexible (avoid splicing the strands!), with ends.
- A single conductor per securing point.
- Make sure that the wires are correctly connected to the terminal block. Incorrect
connection can cause operating problems as well as overheating which can cause fires.
• Wiring must be secured with cable clamps.
4.3.3 - POWER SUPPLY
• 230V / 1+Earth / 50Hz power supply from a power supply and protection device (not included) in accordance with with the
rules in force especially NFC 15-100 (
• The voltage variation tolerance is ± 10 % during operation.
• Max. protection rating: 6 A.
• Max. current consumption: 0.28 A.
• Section of power cable: 1.5 mm
• Connections are made on the unit's terminal strip (terminals U, N and ground).
