VALVE KIT - CODE 70600089
• The valve kit includes:
- the
valve body,
- 2 swivel couplings,
- 4 adapter couplings,
- actuator (with 230V "On / Off" heating element).
Assembly
A - Valve directly on the unit's hydraulic connections
• Fit the 3/4" male - 1/2" female adapter couplings on the
unit's female connectors, then screw the "2 part" portion of
the swivel couplings onto the adapter couplings. Use a
stepped spanner or a hex wrench.
Put sealing compound or Teflon tape on the threads.
Important: Hold the unit's couplings with a wrench while
tightening to avoid twisting the tubes inside the unit.
• Fit the 3/4" female - 1/2" male adapter couplings on the
valve, then screw the "1 part" portion of the swivel couplings
onto the adapter couplings. Use sealing compound or
Teflon on the threads.
• Fit the valve on the unit at the level of the swivel couplings.
The valve is installed at the unit's water outlet.
• Install the thermal actuator on the valve and connect the
cable in the electrical box between terminals 21 and 22 on
the printed circuit board terminal strip X4.
• Mount the auxiliary tank (supplied with the unit) on the side,
below the valve. House the tank's fitting in the hole
underneath the valves. Secure the tank with the two screws
provided.
B - Valve distant from the unit's hydraulic connections
• The valve can be installed on a pipe (not supplied) enabling
it to be offset from the unit's hydraulic connections.
In this case, place the valve along the unit, on the side so
that it is above the auxiliary tank.

7 - STARTING

Before doing any work on the air conditioner, make sure it is switched off and put out of bounds.
Any work must be carried out by personnel qualified and authorised to work on this type of air conditioner.

7.1 - PRELIMINARY CHECKS

• Make sure:
- that the air handler is well fixed,
- that the power cables are well fixed to their connection terminals,
- that the electric cables are properly insulated from any pieces of sheet or metal parts which could damage them,
- that the unit is connected to earth,
- that no tools or any other objects have been left in the unit,
- that the filter is correctly fitted,
- that the coil is clean,
- the hydraulic couplings are correctly tightened,
- that the condensate discharge outlet is correctly connected,
- that the condensate drain pan is clean,
- that the condensate discharge outlet pipes are securely fastened.
