1.- RECOMMENDATIONS
Disconnect the voltage before carrying out any operations inside the electrical panel.
All wiring should be according to current standards and should be carried out by authorised staff.
Only carry out the wiring foreseen in the wiring diagrams.
Using the electrical panel not observing the manufacturer's instructions may alter the appliance's safety requirements.
Panel installation:
It is advisable to leave a clean safety space without obstacles around the panel.
Do not knock or move the panel abruptly.
Carry out the wiring according to the installation manual.
The probes and their cables should NEVER be installed in a conduit together with power, control or feeder cables.
The earth terminals that the panels contain are installed to guarantee the continuity of earthing, however, earthing is
not carried out by the terminal and should be carried out outside the panel.
The neutral ratings are of the TT type. The IT rating should not be used.
Circuit breakers (protective switches) are of the phase/s + neutral, curve C type, guaranteeing switching and protection
against overcurrent.
Close the panel when your are not working on it.
Residual current protection outside the electrical panel according to low voltage electrotechnical regulations.
The panels have been tested using European standard IEC 60439-1.
Checks before starting the panel up:
Power supply voltages and frequencies will be the ones that figure in the "Technical specifications" section.
Check that there are no loose parts or foreign bodies on connections or switchgear.
Check that there is no dust or damp inside the panel.
Check the correct fastening of the switchgear and components.
Check the correct tightening of the screws and power connections.
Check the correct connection of the power conductors.
Check the correct insulation of the outer lines and that they do not mechanically force the inner connections of the panel.
Check that the maximum current of the Q1 current breaker.
Before starting the installation up, we recommend preheating the compressor's housing (Page 15).
Checks during the panel start-up:
Check that no electric arcs occur.
Check that the relays or contactors do not produce ratios.
Check that there is no overheating in cables, controllers and the rest of the switchgear.
Checks after the first 24 hours of operation:
Check that no overheating occurs.
Retighten screws and power connections.
Periodical preventive maintenance:
The panel should remain closed using its lock.
Retighten the power connections once a year.
Check the wear of the switchgear once a year.
Clean the outer surface of the panel with a soft cloth, water and detergent. Do not use abrasive detergents, petrol,
white spirits or solvents.

2.- INSTALLATION
- Remove the four silicone protections (1).
- Make 4 holes on the wall with the dimensions indicated in the drawing.
- Fasten the panel to the wall using 4 suitable screws, washers and plugs.
- Before making the wiring, remove the bottom cover (2) and make suitable holes in it for the cable entry.
Use a gland to maintain the indicated degree of protection.
- Assemble the cover again with the glands. Do not forget to install the sealing gasket correctly (3).
- Wire all the elements, passing the cables through the glands and following the diagrams in the “Wiring” chapter.
- Correctly adjust the maximum current of the Q1 current breaker.

CONDENSATION
PRESSOTAT
-The sum of the consumption of the condenser and evaporator fans should not exceed
5A. If this is exceeded, the fans will be distributed among their corresponding outputs
and the auxiliary output (Terminals 24 and 25) so that the maximum allowed con-
sumption is not exceeded in any of them.
The fans connected to the auxiliary output should include a condensation pressostat
for control, as shown in the following diagram.
-If the fan does not have a pressostat, connect it together with the compressor.
The maximum consumption of the Compressor-Fan group should be in
accordance with the adjustment of the Q1 motor protector.

5.- PARAMETER CONFIGURATION
The AKO microcontroller has been factory configured for optimum operation in most refrigerated installations.
Refer to the following table to check that this configuration is adapted to your needs. If you want to change a parameter,
refer to the microcontroller's manual.
The unit operating parameters are organised in different groups or families according to their function.
The Default values column indicates the factory configured default parameter. The “PARAMETERS ACCORDING TO
APPLICATION” indicates the variable parameters depending on the application chosen in parameter P3.
Unless otherwise indicated, the temperature values are expressed in ºC. (Equivalent temperature in ºF)
IMPORTANT: The AKO microcontroller is factory configured to obtain the best operation in combination
with the panel, therefore, its configuration is slightly different to the one shown in its manual. Refer to the
following table to know its real configuration.

AKO Microcontroller (1)
Refer to the attached microcontroller manual about this device operation.
Main switch (7)
Starts up (pos.1) or stops (pos. 0) the control panel.
As a safety measure, the door cannot be opened when the panel is operating.
Control selector (9)
It allows selecting the compressor control.
ŸPosition 0 (Stop): In this position the compressor will never start to operate.
The crankcase's resistor always activates when the main switch is in
position 1.
ŸPosition 1 (Pump down): The compressor starts to operate pump down (closed liquid solenoid)
until the low pressure switch stops it.
ŸPosition 2 (Run): The installation will operate autonomously controlled by the panel.
6.3- Indicators
High pressure switch indicator (3)
Indicates the activation of the high pressure switch.
Low pressure switch indicator (8)
Indicates the activation of the low pressure switch.
Thermistor alarm indicator (4)
Indicates the activation of the compressor's thermistor.
Current breaker alarm indicator (5)
Indicates the activation of the compressor's current breaker.
Compressor operating indicator (6)
Indicates the activation of the compressor.
IMPORTANT: Before starting up the installation, we recommend preheating the compressor's crankcase,
and to do so, first turn the control selector (9) to position 0 and then the main switch (7) to position 1.
After ten minutes you can start-up the installation turning the control selector to position 2.
