5.1 PRELIMINARY CHECKS
Make sure:
• That the water circulates correctly in the air handler.
• That the heat exchanger has been purged.
• That the fittings are correctly tightened.
• That there are no leaks.
• 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
units (specially form packing-pieces in the discharge
louvers).
• That the filter is correctly fitted.
• That the condensate discharge outlet is correctly
connected.
• That the condensate collection tank is clean. Particles can
damage the condensate lift pump (if fitted).
5.2 SWITCH ON THE UNIT
• Using the isolation and protection device.
5.3 STARTING
• Through the On/Off switch located on the room thermos-
tat.
• Select one of the three ventilation speeds using the switch
provided for this purpose on the room thermostat.
• Move the temperature setting wheel in order to check the
operation and direction of action of control (*):
- In cooling mode, the fan is operated if the ambient
temperature is above the setpoint.
- In heating mode, the fan is operated if the ambient
temperature is below the setpoint.
• Adjust the temperature setpoint value to the required va-
lue.
• If necessary, adjust the position of the vertical deflection
louvre using the "SWEEP" switch on the front of the air
handler (take care of flap movements).
Do not move the flap by hand, as it is motorised.
(*) In the case of adjustment on the valve, ventilation is perma-
nent
Note:
A fuse on the printed circuit board next to the air handler's
terminal board protects the circuits (see diagram)
Fuse rating : 2A GI 250 V
Fuse size
: 5 x 20
5.4 CONDENSATE LIFT PUMP SYSTEM
Factory-fitted accessory.
• It consists of a float type water detection unit which receives
the water collected by the collection tank placed under the
heat exchanger and of a pump unit which sucks the water
from the detection unit.
• The pump's discharge is to be connected as indicated in §
4.1.
• It is necessary to clean and/or change the filter in the
detection unit (frequency according to handler's operating
conditions). See § 6 - maintenance.
• 5 spare filters are supplied with the air handler.
• When reassembling, make sure that:
- the unit is perfectly level
- the float is not stuck (and its locating stud is facing
upwards)
- the pipes are correctly connected (no leaks).
CAUTION :
Stop the air-conditioning system 30 minutes before any
switching off of terminal units, in order to discharge residual
condensates (and avoid inadvertent overflows).

IMPORTANT
Before doing any work on the installation, make sure it is switched off and put out of bounds.
