Vacuum Hose Reel Series 881 EX
EN 5Description of ATEX products
Vacuum Hose Reel Series 881 EX, marked with the EX
symbol are protection level Dc equipment according to
directive 2014/34/EU.
This means that models with the EX symbol may be
placed in areas classified as zone 22 according to dir-
ective 1999/92/EC.
5.1Category limit
The function of the Vacuum Hose Reel Series 881 EX
is to be a part of an extraction piping system. Even if
the product with EX symbol is category 3D equipment
for use in zone 22 (881 exterior), it can be used with a
piping system internally classified as zone 20 or 21.
Since there is no internal ignition source inside the
reel, it is to be considered as simple piping and does
not fall under the scope of the directive 2014/34/EU.
6Mounting instruction
The maximum mounting height for the reel is 4
m. See Figure2.
Make sure that the surface, on which to mount the
reel, is level. Drill four holes, using the hole template
which comes in the package.
1 Fit the mounting brackets in such a way that it will
make the reel hanging horizontally. Ensure that
suitable fixing bolts are used considering the ceil-
ing or wall construction material. The bolts must
each stand a tractive force of a minimum of 3500
N.
2 Lift the reel up and fasten it in the brackets.
1 Wall mounting
2 Ceiling mounting
3 Pull out the safety lock.
4 Put the hose through the outlet of the outlet arm.
5 Fit the hose stop in the required position on the
hose.
6.1Safety lock
WARNING!Risk of personal injury
The reel is equipped with a safety lock that
should be used during service or repair work on
the reel, for example when placing the hose.
NOTE!
When replacing the spring the spring power
must be completely neutralized (instruction is
delivered together with the spare part spring).
6.2Mounting/Replacing the hose
See Figure3a.
When the reel has been mounted on a wall or ceiling,
the hose is replaced in the following way:
NOTE!
Ensure that the drum is locked by the safety
lock, see Figure9/A.
NOTE!
Use only Nederman hoses.
1 Remove the cover plate.
2 Remove the old existing hose.
3 Fit the existing hose coupling to the new hose end
and fit the new hose on the connecting piece in-
side the drum.
NOTE!
For the length of hose from swivel to
clamp, see Figure3b.
4 Fasten the new hose with the hose clip on the
drum according to the picture.
5 Fit the cover plate.
6 Unlock the safety lock.
7 Let the hose recoil by turning the drum by hand.
Make sure that the hose forms evenly divided on
the drum.
8 Fit the hose stop in the desired position, see Fig-
ure3c.
6.3Ratchet mechanism
See Figure4 and Figure5.
The hose reel is delivered with a ratchet mechanism
which retains the hose in the required out-drawn po-
sition. The ratchet will disengage if the hose is drawn
out a little further, and the hose then recoils to the
drum.
NOTE!
The hose should be held by hand as long as
possible during the recoiling.
The ratchet is factory set for wall mounting of the
reel, see Figure5/A. When mounting the reel in the
ceiling, the ratchet must be moved from one position
to another, see Figure5/B, C.
NOTE!
The ratchet must, after it has been mounted,
point towards the centre of the reel.
