1 INTRODUCTION
1.1 Identication of the product
The identication plate contains, among other things, the
following data:
- product name
- serial number
1.2 General description
The Spring Operated Exhaust Hose Reel (SER) removes
exhaust gas fumes from a facility and prevents extraction
hoses from trailing over the workshop oor. SER takes up a
small space, can be mounted to the ceiling or on a wall, and
functions best in workshops with xed working areas. SER
includes either one or two heavy-duty springs that are factory
installed to the outside of the reel assembly; an operator pulls
the hose down to a convenient position, which locks the hose
in place; when no longer needed, the operator recoils the hose
by pulling down on the hose, allowing the hose to recoil in a
controlled manner.
1.3 Product combinations
The SER can be used in central systems or with a direct mount
fan kit. It is designed to operate with hose diameters of 100,
125, 160 and 200 mm (4, 5, 6, and 8 in.).
Note: Direct Mount fans are NOT available for the 200 mm (8
in.) version.
1.4 Technical data
SER contains a high-quality sealed coil spring cassette (an
additional cassette can be factory installed to increase lifting
capacity), which is enclosed in a sealed metal casing. The
spring cassette is located on the outside of the hose reel
assembly to simplify replacement, if needed. The maximum
length of the hose depends on the weight as well as the
installation. The SER maximum lifting capacity is 18,2 kg (40
lbs) with a single spring cassette, and 34 kg (75 lbs) with two
spring cassettes.
Fig. 1.4 SER hose reel with hose
Note: The optional second spring cassette is available for 850,
1050 and 1050-200 models only.
A. Hose reel drum provides a secure and space-friendly
storage location for the hose:
- smooth, zinc-plated drum on which the hose rolls;
- drum end plates are powder-coated yellow.
B. Console - zinc-coated steel frame provides support and
strength for longevity and robustness.
C. A-frame - Primered and powder-coated steel.
D. Ratchet lock (not shown) holds the hose in the required
position. The hose is released at the next pull.
E. Hose - must be ordered separately; the MAS kit must be
ordered separately and includes a hose stop-ring with
clamp so that the hose stop can be positioned for adequate
height on return.
F. High quality sealed coil spring cassette (an additional
cassette can be factory installed to increase lifting capacity),
which is enclosed in a sealed metal casing.
Note: The 200 mm (8 in.) reel has a 200 mm (8 in.) duct
connection tting.

1.4.1 Maximum hose length
The maximum hose length that SER supports is dependent on
these factors:
- the specic version of SER hose reel ordered;
- the type and size of the hose;
- the nozzle;
For example, a 125 mm (5 in.) standard hose can be wrapped
around the drum for a maximum of ve rotations, which would
equal 8,2 m (27 ft). The table below demonstrates the total
weight of the Plymovent EF hose, REGD nozzle and rubber
hose stop. Each system’s total weight will vary.

lengths and maximum hose reach, as shown in g. 4.2.2.
Fig. 4.2.2 Mounting hose reel on ceiling
WARNING!
After installation, operators must be made aware
that a “quarter turn” of the hose should always
remain on the drum, as shown in g. 4.2.2a.
If the hose is pulled down completely, the entire
hose is removed from the drum and the recoil
mechanism is locked. The hose reel will no longer
retract the hose. If this occurs, the drum must be
turned manually by the drum plate for the recoil
mechanism to release.
CAUTION!
When the reel is mounted to a rigid structure like an
iron beam or concrete, then use the dimensions
provided. However, when the reel is being mounted
to porous or otherwise doubtful materials like hollow
brick, threaded rod, lightweight concrete, plaster
etc., please consult a Plymovent expert.
Fig. 4.2.2a Example of SER showing
that at least a quarter turn
of hose must remain on
drum to prevent recoil
mechanism from locking.
ATTENTION
When horizontally mounting a reel that contains
either a 150 mm or 200 mm (6 in. or 8 in.) hose, it
is recommended that you attach the hose so that it
rotates around the “front” of the hose reel drum
(away from the column or wall).
This will prevent the hose from scraping the
horizontal “console” bar, or colliding with any items
attached to the column or wall below the reel.

4.3.4 Factory-installed mechanical damper
Based on the facility design requirements, a sealed closing
damper, as shown in g. 4.3.4, may have been factory
installed on the duct portion of the hose reel. In a facility that
includes multiple hose reels, this
built-in mechanical damper allows
airow only through hose reels
currently in use, reducing energy
costs. The damper opens
automatically when the hose is
lowered (2 rotations), and closes
when the hose is raised by the
operator.
This damper is typically used when
there are no other dampers
installed in the duct work, and no
electronic control units are being
installed.

position. See Fig. 5.1 and follow the steps below.
• Dismantle edge list (C), drum lid (A), and clamp (B).
• Loosen hose clip (E) on the connecting socket and remove
the old hose.
• Attach new hose, bend it into a natural soft curve and
fasten it using clamp (B).
• Re-mount the drum lid (A).
• Re-mount the edge protection (C) at the opening of the
drum where the hose protrudes. The reel is ready for use.

5.2 Replacing the spring cassette
• As shown in g. 5.2, take o the hose stopper and tailpipe
adapter (A) and allow the hose to completely coil onto the
reel (B).
• Turn the reel four revolutions ”backwards” in order to
equalise the spring-tension (if the spring still functions).
• Unscrew all socket head cap screws at the spring casing
(C). Mark the position of the spring casing.
• Put the new spring casing in position. Tighten the bolts
evenly.
• ”Pre-tension” the reel about seven revolutions. Put the
hose stopper in position.
5.3 Exchanging the plastic bearings
To safely perform this operation, it is recommended that you
dismantle the reel and stand it on the oor. See Fig. 5.3 and
follow the steps below.
• Make sure hose is completely rewound on the reel. Turn
the reel approximately seven revolutions ”backwards” in
order to cancel the spring-tension (A).
• Loosen the leg on the side of the spring by loosening the
bolts on the beam (B).
• Remove the drum from the reel.
• Change the plastic bearing (C).
• Unscrew the drum lid (D). Dismantle the connecting socket
(E) and change the plastic bearing (F).
• Reassemble in reverse order.

After life of the product, dispose it of in accordance with state
or local regulations.
7 PRESSURE LOSS CALCULATION
The fall of pressure in a air duct system or in a hose is mainly
determined by the air velocity in that system.
The higher the velocity is, the higher the pressure loss will be.
And the higher the pressure loss is, the less air the fan will
extract. See g. 7.1 for a Pressure Loss Chart to identify a
suitable fan regarding the relationship between airow and
pressure loss.
In a ventilation system with many extraction devices and long
suction ducts, you can minimise pressure loss by increasing
the size of the ducting. This will also ensure even velocity
throughout the system.

When 1200 to 1350 m3/h is needed, Plymovent recommends a
150 mm (6 in.) hose. A 200 mm (8 in.) hose can be used for
larger applications, as it supports larger engines operating
under load. For those cases, the exhaust ow and temperature
increase dramatically.
Air velocity in ducting: 17,8 - 22,9 m/s (3500 to 4500 fpm).
The chart below shows the pressure loss in the hose reels a
dierent airows. Refer to the Airow Volume: General
Guidelines table below for the vehicle, airow and hose
diameter guidelines. The curves show these combinations of
hose reel/hose diameter/hose length (uncoiled position).
We recommend that you conrm existing exhaust
temperatures to ensure proper hose, fan and
airow selection.
