MAINTENANCE AND TROUBLESHOOTING
DANGER - ELECTRIC SHOCK RISK
Make sure the machine is disconnected from electric power supply, before performing mainte-
nance operation.
In ordinary conditions, BOOSTER SETS FLOTEC do not require any maintenance. To prevent possible problems, it
is advisable to periodically check the pressure supplied and current absorption. A reduction of the pressure may
indicate that the electropump is worn. Sand and other corrosive materials present in the delivery fluid cause a rapid
wear and a reduction of performance.In this case, it is advisable to use a filter and select an appropriate filter cartri-
dge according to the application. An increase in current absorption indicates the presence of abnormal mechanical
friction in the pump and/or the motor.
To avoid problems, it is advisable to regularly check the pre-load pressure in the tank. At this point, disconnect the
pump from the mains and open the water supply to remove the pressure from the system. Then, measure the pre-lo-
ad pressure using the valve on the rear side of the tank. Perform the measurement with an independent pressure
gauge. Pressure should be equivalent to 1.5 bar. Correct the value if it is incorrect.
If the electropump is not going to be used for a long period of time (i.e. one year), it is advisable to empty it comple-
tely (by opening the drain cap, see Fig. 1 n. 10), rinse it with clean water and store it in a dry location, where it can be
protected from frost.
