RESTARTING

After switching off the main OFF button OR after power supply interruption.
Press the VENTILATION operation button (The appliance will restart on the previous settings)

PROTECTION AND SAFETY DEVICES

ELECTRICAL

1. Fuses on the single phase circuit
2. Thermal protection on the compressor contactor
3. Thermal protection on the fan motor

REFRIGERATION

1. High and Low pressure safety switch with manual reset*
2. Compressor starting protection heating resistance (option)

FIRE

1. Thermal protection with manual reset
*on the incorporated heating resistance (option)
2. g)Flameproof air filter

FREEZING

1. Water condenser freezing protection purge plug.
2. In the case of total rear air intake, the aspirated air passes through the appliance. The installer must
provide, if necessary, condenser water anti-freeze protection.
3. The fan motor internal safety device and the heating thermal protection device shut down ventilation
and the control circuit driven by the ventilation. They are reset by pressing the VENTILATION on
button.
4. The safety pressure switches and the external compressor safety device shut down the COOLING,
without shutting down ventilation. They are reset by pressing the pressure switches or the compressor
thermal relay manual reset buttons.
Comment
When a safety device is activated it indicates an operating anomaly and requires in-depth investigation. In fact, it can
be caused by an electrical anomaly (voltage drop), by low compressor output (water output, water temperature...),
by treated air intake conditions (abnormal output, exceptional temperature) and could require remedial action.
remove the front air intake grille for access to the safety resets.

MAINTENANCE

AIR FILTER

To maintain good appliance performance, it is recommended to regularly check the air filter in relation to local
dust conditions. Shake it or vacuum clean it; The air filter should only be removed for cleaning when the appliance
is stopped.

FILTER ACCESS

After removing the air intake grille, held in place by locks. The filter is held in place against the evaporator.
Treated air fan motor: greased for life.
