Gas injection valve cleaning
Once depressurised the system and at a pump temperature of around 80-100
ºC, release the two screws securing the gas valve to the pump.
Then remove the gas valve, and disassemble it.
Note: The thread between the two main pieces is left thread.
Clean all parts in case they have adhesive residues and reassemble as shown

Motor-gear maintenance
Cleaning the motor fan
Periodically inspect the condition of the motor fan and its vent screen.
If dust has accumulated, blow gently with air to clean it (remove the protective
cover, if necessary).
Checking the lubricant
The gear reducers are delivered filled with synthetic grease for lubrication
-free of outside contamination- ‘for life’. Ambient temperature 0 ÷ 40 °C, with
peaks of as low as -20 °C and up to +50 °C.
Use only those lubricants recommended by the manufacturer. The use of other
types may cause premature wear or damage to the gear reducer.
If the unit features a 0.375 kW gear motor, its gearbox will have a capacity for
approximately 0.19 kg of lubricating grease. In the case of 0.55 kW, 0.75 kW
and 1.1 kW gear motors, the gearboxes need at least 1.1 litres of lubricating
oil.
