Exhaust Hose Reel 865
EN
4.4 Ratchet device
See
. The reel is fitted with a ratchet device
which lock’s the hose in the desired position. The
ratchet is released when the hose is pulled out slightly
further and the hose is then automatically recoiled.
The ratchet is factory set for ceiling mounting of the
reel (position A). When mounting the reel on a wall,
the ratchet must be moved from position A to B.
NOTE!
The ratchet must, after it has been mounted,
point towards the centre of the reel.
4.5 Duct connection
See
. The connection hose supplied with the
reel should be used for connecting the reel to duct
systems and a central fan.
* Hose clip.
NOTE!
The duct must be fitted with hose clips. Do not
drill or fit with screws.
4.6 Fan positioning
A suitable fan can be selected from the Nederman fan
range. To avoid leakage in the ducting system the fan
should be positioned outdoors or as near the duct out-
let in the room as possible.
4.7 Adjustment of spring tension
See
. The reel has a factory-set basic spring
tension which after mounting the reel with hose and
nozzle could need an adjustment.
NOTE!
Do not tension the spring more than is needed
to exactly roll the hose to its position of rest.
4.7.1 Increasing the spring tension (moun-
ted reel)
1
Make sure that the hose is in place and fully re-
coiled on the reel.
2
Pull the hose out a little and make sure that it is in
the engaged position. Push the safety catch (A).
3
Use the socket head cap spanner which comes
with the reel. Turn in the direction of the arrow as
shown in the picture.
4
Tension the spring in small steps and test the coil-
ing operation gradually.
5
Draw out the safety catch (A). Check that the hose
can be fully uncoiled without stretching the spring
to its maximum.
4.7.2 Decreasing the spring tension (moun-
ted reel)
1
Make sure that the hose is in place and fully re-
coiled on the reel.
2
Push the safety catch (A).
3
Remove the hose stop and nozzle.
4
Remove one coil of hose.
5
Refit the hose stop and nozzle.
6
Draw out the safety catch (A).
4.8 Damper function
. The reel is fitted with a mechanical
damper which automatically opens when the hose is
pulled out. The damper closes when the hose is re-
wound.
The damper is equipped with a red and green marks:
• A, red mark: the damper is closed
• B, green mark: the damper is open
4.9 Directions for use
4.9.1 Connection
Pull the hose out to the desired position and make
sure that it is in the engaged position. Connect the
nozzle to the vehicle exhaust pipe. See
.
WARNING! Risk of personal injury
• Check that there is enough suction in the
exhaust hose before it is connected to the
vehicle’s exhaust pipe. If not, check the fan’s
rotation direction and/or damper function. If
necessary check installation of the fan start
switch.
• An exhaust gas detector is recommended.
4.9.2 Disconnection
Disconnect the nozzle from the vehicle exhaust pipe.
Draw the hose out a little to disengage the ratchet.
The hose now recoils to the drum and it should be held
by hand until it has moved to its end position. Make
sure that the hose only forms one layer on the drum.
See
4.10 IMPORTANT!
. If the hose is pulled out too far, the
ratchet could, unfortunately, become permanently
locked. It may be released by the following procedure.
1
Take a steady grip on the drum end plate and turn
a little in the outdraw direction until the ratchet is
disconnected.
2
Holding the endplate and hose at the same time,
then slowly releasing until the hose has recoiled.
3
Fit the ratchet in the other mounting position.
