2.8 CIRCULATION PUMP ALARM
If during initial start-up, AL6 appears on the control panel display after starting the circulator, check that the system valves are
open, that there is at least one utility with the circuit open, that the external sieve filter is not clogged, that there are no air bubbles
in the circuit, that the system water pressure is correct and that the circulator is not blocked.
To cancel the pump alarm and restore proper working efficiency, press the Reset icon on the display and confirm.
2.9 ELECTRICAL CONNECTIONS (fig. 20, 21, 22, 23)
• The electrical connections must be made in compliance with the instructions given in the installation manual and with national
standards or procedures governing electrical connections; insufficient capacity or incomplete electrical connections may lead
to electric shock or fire.
• Warning: the power circuits of the internal and external units must be separate; the external unit line must be
protected with a thermomagnetic circuit breaker or suitably sized fuses.
• Never use a power source to which another appliance is connected.
• For the connection, use a cable long enough to cover the entire distance without the need for intermediate connections; do
not use extension cables; do not apply other loads to the power supply, use a dedicated power supply (failure to do so may
lead to a risk of overheating, electric shock or fire).
• For the electrical connections between the internal and external unit, use the specified types of cables; fasten interconnection
cables securely so that the respective terminals are not subjected to external stress using the cable grips inside the unit;
incomplete connections or fastenings may lead to overheating or fire.
• After having connected the interconnection and power cables, ensure that the cables are not exerting any strain on the covers
or electric panels; fit the covers on the cables.
• Should any refrigerant leak out during installation, aerate the area (if exposed to the flame, the refrigerant produces toxic
gas).
Ensure the power supply to the external and internal units is off before carrying out any operation.
For the electrical connections see figures. 20, 21, 22, 23 and Para 2.9.2 Connecting cables.
The power voltage must be that stated in the technical features table.
The cable terminals must be equipped with leads with section proportionate to the connecting cables before being inserted into
the terminal board.
The power lines must be suitably sized to prevent voltage drops or overheating of cables or other devices on the lines.
The power line of the external unit must be capable of being sectioned from the mains using a thermomagnetic circuit breaker
suitable for the machine input with differential relay, with maximum calibration equal to that stated in national electrical regulations
(see table in fig. 23).
The internal unit line is already protected by a thermomagnetic circuit breaker on the electrical heater elements power supply
and by a fuse (see sect. 2.1.2); installation of a differential relay on the power line is recommended.
Check that during the compressor operation the electrical power voltage corresponds to the nominal value +/-10%.
Using the refrigerant or water pipes to earth the appliance is forbidden.
The manufacturer is not liable for any damage arising from failure to earth or failure to comply with that indicated in the wiring
diagrams.
The table in fig. 23 shows the maximum inputs of the units.
A External unit power supply
B External unit maximum absorbed power
C External unit maximum absorbed current
D Fuse or thermomagnetic circuit breaker (MFA)
E Internal unit power supply
F Internal unit maximum absorbed power (with electrical heater elements activated)
G Internal unit maximum absorbed current (with electrical heater elements activated)
2.9.1 Access to electrical connections
The terminal boards for the external unit’s electrical connections are located on the right-hand side of the unit. To gain access,
remove the electric panel cover after having removed the fastening screws.
To access the terminal boards for the internal unit’s electrical connections, see sect. 2.1.1 and 2.1.2.
These operations are permitted solely to specialist personnel.
