4.2 CONNECTING THE CONDENSATE DISCHARGE PIPE(For air handlers which can operate in cooling mode)

• Connect the condensate pipe to a discharge pipe.

• For the units not equipped with a condensate drain pump, use a flexible tube of internal diameter 18 mm to be fixed on thecondensate tube's end piece.

• For air handlers equipped with a condensate drain pump, the pump discharge is connected to a flexible PVC pipe of internaldiameter 6 mm, equipped with a splined connector.See the "Technical Manual" for the pressures available at the discharge.

4.3 HYDRAULIC CONNECTIONS

• Air handlers can be connected either with metric copper pipe or with PER(interlaced polyethylene).

• Diameter of the pipes to be used :- KPW 2 :

- copper pipe 10/12 or- PER pipe 10/12

- KPW 3 and KPW 5 :- copper pipe 14/16 or- PER pipe 13/16

• Adaptors for copper pipe or PER pipe are supplied with the air handler.

P.E.R. pipe

INSULATION OF PIPES• The insulation concerns the water return and inlet pipes.• Use polyethylene sheathing at least 9 mm thick.• After connecting the pipes and checking for leaks, put the insulating sleeves on the

fittings in order to prevent condensation.

Note : This operation must be done carefully to avoid any risk of condensation.

IMPORTANT NOTE

• If the end of the condensate discharge pipe goes into thewater and forms a trap, the flow will not be correct and thecondensate will flow in the internal unit (see drawingopposite).

• Check that the condensate is discharged smoothly.

• Seal the hole in the wall through which the pipes pass inorder to prevent water entering.

• Using a bottle, for water into the condensate tray in orderto ensure that the water is correctly discharged.

• The wiring of the thermostat shown opposite correspondsto control in cooling mode with action on the ventila-tion (standard assembly).

To have access to the terminal board :

• Remove the front suction grille and remove the powersupply unit cover (1 screw).

• Then prepare the wires and connect them to the terminalboard (passing the wires through the openings providedfor this purpose).

• Note : on certain devices, the terminals are of the "cagewith 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 board. Incorrect connection can causeoperating problems as well as overheating which cancause fires.

• Note :It is possible to obtain temperature control by actuating atemperature control valve (not supplied) operating in on-off mode and feeding the terminal unit.In this case, ventilation is permanent.Valve power supply: 230 VAC (Max. intensity = 0.5 A in-ductive).

• It is possible to invert the direction of action of control andthus to change to heating mode by connecting thermostatterminal 19 to the installation's neutral which can be foundon thermostat terminal 4.

• For installations which can operate in cooling mode or inheating mode, it is possible to connect a contact which :

- if it is closed, connects terminal 19 to the installation'sneutral and causes the installation's thermostat tooperate in heating.

- if it is open, isolates terminal 19 and causes the controlthermostat to operate in cooling mode.

• This contact (not included) can come for example fromhydraulic module MH.

Note : The same contact can control the mode change-over of several room thermostats provided :

- That the length of the wire connecting to the change-over contact does not exceed 150 m (wire of section 1.5 mm2).- That the neutral on which the change-over contact is connected is the same as the one for the various air handlers.- Do not run this control cable near power cables in order to avoid interference.

• Remove the cover of the control thermostat case.

• Remove the probe inside the thermostat shown opposite(by cutting this component's fixing lugs using pliers).

• Enables the control thermostat to be put outside the premises to be air-conditioned.The probe connects to the thermostat.

• Fixing :- Make sure that the installation is switched off.- Open the probe case cover.- Fix the probe case in the required place, following these rules :

- Avoid draughts- Avoid any unwanted heat source which could affect the probe (sunlight, proximity

of supplementary heaters, lights, chimneys, television sets, etc.)- Make sure that the probe is in the normal convection currents.

5.4 CONDENSATE DRAIN PUMP SYSTEMFactory-fitted accessory.

• It consists of a float type water detection unit which receivesthe water collected by the collection tank placed under theheat exchanger and of a pump unit which sucks the waterfrom the detection unit.

• As the condensate detection unit is fixed in the factoryfor console assembly, this unit must be relocated asindicated in § 3.4 - fig F.

• The pump's discharge is to be connected as indicated in §4.1.

• It is necessary to clean and/or change the filter in thedetection unit (frequency according to handler's operatingconditions). 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 anyswitching off of terminal units, in order to discharge residualcondensates (and avoid inadvertent overflows).

5.1 PRELIMINARY CHECKSMake 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.• 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 drain 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 verticle deflection flap position by

using the “SWEEP” switch located on the cover of theelectric box (see § 4.4.4).Do not move the flap by hand, as it is motorised.

(*) In the case of adjustment on the valve, ventilation is perma-nent
