Inspection procedures
Engine coolant inspection
► Remove the pressure cap from the compensation tank at room tem-
perature. The coolant should be between the MIN and MAX markings
in the compensation tank.
► If necessary, fill the tank with coolant and fit the pressure cap.
Use VOLVO VCS coolant for the initial filling.
Coolants may not be mixed together.
Temperature stability control
► Remove the pressure cap from the compensation tank.
► With the coolant probe, check the temperature status. This should be
at least -20 °C.
Leak testing
The check for leak tightness should be done every 3 months, after a com-
plete drainage of the portable fire pump.
► Drain pump carefully.
► Open drain cock (J7).
► Close the suction inlet (J15) with a blank cap.
When checking suction hoses, connect them to the suction inlet
and close the end with a blank cap.
► Close pressure valve(s) (J10)
► Actuate Priming pump function switch (S3) to activate the priming
pump.
If only the pump is checked, a vacuum of 0.8 bar is reached in a few
seconds.
► The pump is tight enough, if the vacuum does not drop below 0.1 bar
within one minute.
If 0.8 bar cannot be reached, the pump should be put under pres-
sure by water induction. A pressure of 3-6 bar connected to the
suction inlet is sufficient.
The leak check is carried out.
► Release vacuum after the leak check.
► Briefly open the pressure outlet(s) (J10) or drainage (J7).
