Connection duct

See picture, page 4. The connection hose supplied
with the reel, should be used for connecting the reel
to duct systems and a central fan. NB! The duct
must be fitted with hose clips. Do not drill or fit
with screws.

Adjustment of spring tension

See picture, page 4. Reels delivered with hose have
factory set basic spring tension which after mounting
could need an adjustment.
N.B. Do not tension the spring more than is
needed to exactly roll the hose to its position of
rest.
Increasing the spring tension
(mounted reel):
1. Make sure that the hose is in place and fully recoi-
led on the reel.
2. Pull the hose out a little and make sure that it is in
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. Draw out the safety catch (A).
Check that the hose can be fully uncoiled without
stretching the spring to its maximum.
Decreasing the spring tension
(mounted reel):
1. Make sure that the hose is in place and fully recoi-
led on the reel.
2. Push the safety catch (A).
3. Remove the hose stop and nozzle.
4. Remove 1 coil of hose.
5. Refit the hose stop and nozzle.

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 ne-
cessary check installation of fan start switch.

vehicle exhaust pipe. Draw the hose out a little to di-
sengage 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.
