3. PRODUCT DESCRIPTION
The Viking Model VFS-100 Foam Hose
Station is a self-inducting, continuous
flow hose reel station with a foam concentrate supply tank built into the unit.
The Model VFS-100 is designed for use
in flammable liquid storage areas, aircraft hangars, heli-pads, and any other
areas where foam solution handlines
are required.
4. TECHNICAL DATA
8. OPERATION
(Refer to Figure 1.)
An automatic water supply is required to
be connected to the 1-1/2“ (40 mm) inlet.
The foam solution control valve (2) must
be open and the water supply bypass
control valve (1) must be closed to proportion foam. The eductor (3) in the supply loop to the hose reel (7) is connected
to the foam concentrate supply tank (4).
When the hose reel nozzle (purchased
separately) is opened, water passing
through the eductor (3) will cause a
strong venturi effect in the low-pressure
area of the eductor (3). This causes
foam concentrate to be proportioned
into the water stream. After foam concentrate is proportioned into the water
stream, the mixture becomes foam water solution. Foam water solution is then
discharged through the hose, out of the
nozzle, and onto the hazard.
If only water is desired to be discharged,
or if flushing of the hose line is required,
close foam solution control valve (2),
open water supply bypass control valve
(1), and open hose nozzle to discharge
system supply water.

current list price schedule or contact The
Viking Corporation directly.
7. APPLICATION
The Viking Model VFS-100 Foam Hose
Station is used wherever Class B fires
Form No. F_090198
curely mount the device to a horizontal
surface that the unit will rest on. Foam
concentrate is placed in the Foam Concentrate Supply Tank (4) by opening the
foam concentrate fill connection and filling to the appropriate level. The capacity of the tank is 55 gallons. A sealing oil
should be placed over the surface of the
foam concentrate to avoid exposing the
concentrate to air. Note: Foam concentrate will solidify if it is exposed to atmospheric air for extended periods of time.
After the unit has been secured and the
concentrate storage tank supplied, the
water supply can connect to the inlet
connection of the unit. The hose nozzle
is normally closed, the foam solution
control valve is normally open, and the
water supply bypass control valve is
normally closed.

2. MANUFACTURED FOR:
(flammable and combustible liquids) are
stored, transferred, or are used in process operations. The Viking Model
VFS-100 continuous flow foam hose
reel is designed for use in airplane hangars as required by NFPA 409,
heli-decks or heli-pads as required by
NFPA 418, and other areas where flammable liquids are handled. The Model
VFS-100 is a stand-alone foam hose
reel that is not dependent on its supply
piping to be fed from a foam proportioning supply. The VFS-100 is ideal to add
to an existing facility that may or may not
have a foam system in place. If a foam
system is in place and the addition of
hose stations is required, the VFS-100
would not tax the existing foam concentrate supply. If a water system is in place
and the addition of foam hose stations is
required, the expense of a bladder tank
type hose reel can be avoided.

10. MAINTENANCE
(Refer to Figures 1 and 2.)
1. If the hose reel unit was discharged, the foam concentrate
level should be checked. If foam
concentrate has been used, fill the
concentrate to the appropriate
level.
2. If the Foam Eductor (3) requires removal, close the Foam Concentrate Solution Valve (2). Relieve
pressure from the downstream
piping by opening the hose reel
discharge nozzle. After the water
pressure has been eliminated, remove the 1-1/2” Pipe Union (5),
remove mounting bolts, and
unthread the foam eductor from
the inlet piping.
3. If foam concentrate requires removal, close the Foam Solution
Control Valve (2), place a hose on
Foam Concentrate Drain Valve
(17), and place foam concentrate
into a suitable container. Foam
concentrate should be disposed
of in a manner conforming to local
requirements.
4. If the hose is distributed from the
Supply Loop to the Hose Reel (7),
the hose can be retrieved and
re-spooled by winding the Hose
Retrieval Handle (6) clockwise until hose and nozzle are adequately
replaced on the spool.
11. INSPECTIONS AND TESTS
Inspections and tests should be conducted at the frequency required by
NFPA 25 and the Authority Having Jurisdiction.
