8 Maintenance
NOTE:• This procedure must only be carried out when the Envirosorb control is installed inside your dwelling or premises.
• When the control is installed on the appliance, the procedure must be carried out by a competent person, since there is a danger of electrocution.
8.2 GENERAL CAREWARNING:• If you are not planning to use the appliance for a while, never disconnect the circuit breaker.
The appliance must always have a power supply. If the power supply is disconnected, the pump anti-freeze and anti-wear protection devices cannot work. The appliance may be seriously damaged.
• Never shut off the water circuit valves. If the valves are shut off, pump antifreeze and anti-wear protection devices cannot work. The appliance may be seriously damaged.
• Occasionally check the appliance base. If the base is damaged or deteriorated, the appliance could fall down and cause physical or material damage.

Breakdown Solution
Unit does notstart
Check that the main switches of the equipment and the fuses are correctly connected.
Poor heat output
Check that the thermostat controls are set correctly.
If the power supply has been interrupted due to a power cut, the unit has a system protection deviceand operation will restart after approximately three minutes.

Check that the thermostat controls are correctly set.
If the power supply has been interrupted due to a power cut, the unit has a system protection deviceand operation will restart after approximately three minutes.
When the unit is started or stopped, a cracking noise may be heard. This noise is generated as a result of theexpanding or contracting of the housing caused by changes in temperature of the different materials and is quite normal.
Noise is heard When the heating has stopped, a whistling or bubbling noise may be heard.This noise is generated when the refrigerant flows through the unit, this may continue for several minutes after the unit has stopped.
Emits mist In winter and during the defrosting period, a cloud of mist may be produced in the outdoor unit;this is due to the heat melting the ice which has formed.
When the system is in operation a humming may be heard. This noise is generated when the unit defrosts in heating mode and is caused by the reversal of the refrigerant flow.
