Preparations for work
Dry vacuuming with paper filter bag
(Fig C+F)
The Wetrok Duovac 18/25/34 can be fitted
with a paper filter bag.
Fitting the paper filter bag: Unfold paper filter
bag (C2). Pull the rubber flange (F1) from
below on to the suction connection (F2) and
press it firmly against the suction tank wall.
Insert protective filter (C1). Mount suction head
10
so that the mains cable is routed opposite the
connector. Assemble suction hose, hand pipe
and nozzle.
Use only original Wetrok paper filter bags.
Dry vacuuming without paper filter bag
(Fig E)
When dry vacuuming without paper filter bag,
fit the special filter bag (E2) with the water
suction device (E1).
Wet vacuuming (Fig. D)
Fit water suction device (D1 ) in place of the
paper filter bag and the protective filter. Fit
water suction nozzle to the hand pipe.
Duovac 50
The Duovac 50 is equipped with 2 suction
motors; 1 or 2 motors can be switched on
according to the required performance.
4. Maintenance
4.1 Safety instructions
– When cleaning and servicing the machine
or changing parts, pull out the mains
connector plug.
– The machine must not be cleaned with
high pressure steam cleaners or powerful
liquid jets.
– For reparations use only original Wetrok
spare parts.
Important: Before commencing any mainten-
ance work, switch off the machine and unplug
it from the mains.
Emptying dust
Replace the paper filter bag as soon as it is
2/3 full. When working without paper filter bag,
empty the suction tank regularly. At each
emptying, thoroughly clean the protective filter
by beating or brushing. If possible, use another
vacuum cleaner.
Emptying water
When the tank is full, the high positioned float
interrupts the suction flow. Take out the water
suction device and empty the waste water
tank.
The water suction device has always to
be installed tor wet vacuuming.
Wipe the outer surface of the machine,
especially the mains cable, from time to time
with a damp cloth.
5. Corrective
maintenance
We recommend that repairs and inspections
are carried out by the Wetrok Service Agent. A
maintenance agreement is available.
5.1 Fault-finding and rectification
Dry vacuuming:
– Paper filter bag or suction tank overfilled?
– Suction pipe, suction hose or nozzle
obstructed?
– Protective filter coated with dust?
The suction motors of Duovac 50 are provided
with a thermal overload switch, which shuts off
the motors automatically if they overheat. It
switches the motors on again as soon as they
have cooled off.
Wet vacuuming:
– Float sticking to valve aperture?
– Use of a too strongly foaming detergent,
causing float to respond too early?
– Water suction device not correctly positio-
ned?
– No effective sealing between the suction
head and the suction tank?
6. Storage
The machine is to be stored dry and under
normal room conditions.
7. Disposal
Disposal ot packaging must take place accor-
ding to natioral regulations.
