6.1 - PRELIMINARY CHECKS

• Make sure:
E
- that the water circulates correctly in the air handler,
- that the heat exchanger has been purged,
D
- that the connections are correctly tightened and have good
thermal insulation,
- that there are no leaks,
- that the air handler is well fi xed,
- that the power cables are well fi xed 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),

GENERAL MAINTENANCE

All equipment must be properly maintained in order to provide optimum performance over time. Faulty maintenance can result
in the cancellation of the product guaranty. Depending on the products, maintenance operations consist in the cleaning of fi lters
(air, water), internal and external exchangers, casings, and the cleaning and protection of condensate tanks. Treating odours
and the disinfection of room surfaces and volumes also contributes to the cleanliness of the air breathed by users.
• Air fi lter:
- Clean every two weeks. See "Operating instructions".
• Electric connections:
- Once a year, check that the electric wires are well fastened
to their terminals.
• Electric box:
- Dusting is recommended once a year.
• Safeties for electric heating :
- The MPW-BE with electric heating are fi tted with a safety
thermostat with automatic reset and another with manual
reset.
- The latter cuts in when air fl ow is too low or non-existent.
Possible causes :
- faulty ventilation motor,
- blocked or braked turbine,
- fi lters clogged,
- heat exchanger clogged,
- blocked air inlet or outlet.

IMPORTANT
- that the condensate collection tank is clean.
6.2 - SWITCH ON THE UNIT
• Using the isolation and protection device.
6.3 - STARTING
• Via the On/Off switch located on the remote control.
• Select one of the fan speeds using the switch on the remote
control.
• Move the temperature setting in order to check the operation
and direction of action of control.
• Adjust the temperature setpoint value to the required value.
• Adjust the position of the defl ection fl aps if necessary.
IMPORTANT
- Repair the fault, then reset safety thermostat as shown.
• Condensate pumping system:
- This requires regular specifi c maintenance.
- The maintenance cycle is determined by the conditions
of operation (minimum operations to be performed each
time the installation is restarted in cooling mode).
- Clean the condensate recovery tray located under the
heat exchanger and check hoses/pipes.
- Clean with water containing 5% bleach.
