OPERATING TESTS AND ANOMALY DIAGNOSIS
The unit is able to perform a brief auto-diagnosis cycle to check that the internal components are operating normally. During process the
installer can configure the control board based on whether installation was applied near the ceiling or near the floor. To activate the self-
diagnosis function, use the following procedure:
Energize the unit and ensure it’s on stand-by (no LED should be lit on the console)
Press the reset key positioned underneath the hole to the left side of the console (fig. 22 ref. H) with a pointy object for at least 10
seconds. The sound emitted indicates the self-diagnosis function has been activated.
At this point the current configuration of the unit
will be displayed for a few moments as indicated below:
LED A
(red) on: The unit is configured as a heat pump.
LED B
(green) on: The unit is setup for the lower part of the wall (factory default).
LED C
(orange) on: The unit is setup for the upper part of the wall.
LED D
(green) on: Reset settings function after an active black-out (factory setting).
At this point all of the LEDs on the console will start flashing simultaneously for 10 seconds. During this time the configuration of the unit can
be changed by pressing the reset key (fig. 22 ref. H) until the settings match your specific application.
Note:
Configuration of the control board for installation to the upper part of the wall sets an automatic correction of the
detected room temperature detected of 5.5º
At this point the self-diagnostic function activates the appliance in heating mode (if fitted with the heat pump function) for approx.
2
minutes and then in cooling mode for another 2 minutes.
It is possible to terminate the function prematurely simply by
switching the appliance off using the remote control.
Should the unit stop and signal an error, determine which LEDs are flashing then use the chart below to determine the cause: (fig. 22).

WARNINGS DISPLAYED DURING NORMAL OPERATION SHOULD NOT BE INTERPRETED AS ERRORS.
LED A:
Indicates the filter may need cleaning. After cleaning or replacing the filter the LED must be switched off manually as indicated in
section 2.6.1
LED B steady light:
Indicates high battery temperature signal.
LED A + LED C flashing:
Indicates continuous pump operation.
2.5.1
Removing condensate water during an emergency
If there should be a malfunction in the condensation water drain system, the unit stops, then signals, with flashing orange, green and red lights
(the second and third LEDs from the left), the alarm status. To temporarily enable the unit to operate until the service personnel arrive, you
can drain the water out by following these simple instructions:
Remove the lower cover (fig. 23 ref. A)
Place a container to capture the water (at least 10 ounces), the r
emove the cap (fig. 23 ref. B)
After clearing the fault re-install the plug.
2.6
ROUTINE MAINTENANCE
This unit has been designed to reduce routine maintenance operations to a minimum. Cleaning or replacing the air filter at minimum of once
per month or as needed if the red LED lights up. This procedure can be performed by the end user.
Cleaning the condensing battery and condensate management system must be carried out by qualified technicians on a regular schedule
based on frequency of use. Depending on the quantity of dirt, the unit can be cleaned dry by using a battery compressor and bowl.
Clean the fins with a soft brush taking care not to damage or bend them or A more thorough cleaning can be performed using non-acidic,
environmentally friendly detergents.
Before you leaving the site gather up all packing material and use a damp cloth to gently clean the
surface of the unit.
To prevent unnecessary service calls from the user and before leaving the site explain remote control and system operation to the end user.
Also explain how to safely clean the filter by first deenergizing the unit.
