Overview
•This manual is a breakdown and walk through of Walinga's Central Vac System.
•It was created in order to generate efficiency and clarity in the set up of Central Vac
Systems.
•You will find a break down of all the components that are included in a Central Vac
system and how they come together as well as a break down of how the piping
system shall be installed.
•This manual will cover key points and procedures utilized in the construction and
installation of the central vac system.
•Every Central Vac piping system is original and built to suit the customer's needs.
Safety During the Installation of the Central Vac System (Refer to unit manual)
•Ensure that the blower and airlock have no power
and are locked out, before performing service work
on the Central Vac system. Failure to do so may
result in severe injury or death.
•Ensure that all chain guards or moving parts have
their proper guards installed, preventing injury.
•Wear the appropriate protective gear.
•Ensure that the Central Vac is anchored to firm and
level ground.
•Make certain that sufficient
amperage, at the proper voltage and frequency (60Hz) is available
before connecting power for the electric model. Have a licensed
electrician provide power to the machine. Always follow ANSI/NFPA 70
Standard and all local codes when providing electrical power.
•Have at least one extra person available to assist when elevating,
moving or connecting to other equipment.
•Wear appropriate protective gear while working on the Central Vac System.
•Once finished, give the machine a “once over” for any loose bolts, components, leaks,
faulty seals, and proper anchoring.
•Think SAFETY! Work SAFELY!
Key Items to Follow
•Follow Safety procedures.
•Ensure proper sealing of the mating components.
•Inlet placements in the piping.
•Use compression couplings and grounding strips at all joints.
•Keep piping as straight as possible.
•Keep all components within 400' of the Central Vac unit.
•Install Y elbows from the side or from the top of piping, and have the elbows follow the
flow of the air stream.

ypical Central Vac Set Up

◦1. Primary Separator
•Separates the incoming product from the air stream and uses cyclonic action to
send material down to the discharge system. The product, being heavier than
air, will fall down the tank towards
the airlock.
•55” high X 19” diameter.
•Where gaskets are not available
use silicon to seal between
components in order to maintain
a constant vacuum.
•The Primary Separator is bolted onto the
top of the airlock.
•The Primary Separator is equipped with
two ports.
◦The port on the top has a diameter of
6” and will lead to the Secondary
Separator.
◦The suction lines connect to the 4”
side port.

2. Airlock / Rotary Valve
•The airlock is a Walinga 1210 drop thru airlock, built as a single assembly.
•27 1/2” long X 23” wide.
•The airlock will be placed under the primary separator and above the customer's
discharge option, which will be indicated on the piping layout / system design
drawings.
•Discharge piping is 6” and
should be installed vertically with
a maximum of 20deg slope. This
ensures that dust will flow
through spouting using only
gravity.
•The airlock operates off of an
electric motor and chain drive
and has to be placed in an easily
accessible location for service.
3. Secondary Receiver / Separator
•Placed after the primary separator, the secondary separator operates the same
way as the primary. It's purpose is to further separate product from the air
stream.
•It typically ships as two pieces that need to be assembled.
•On the bottom of the secondary separator is a 6” outlet with a mounting plate
built into it. Below this will be a slide gate or a flap seal.
•When equipped with a slide gate 6” discharge spouting will be required.
•When equipped with a flap seal ensure there is enough room below to empty
the cone into an appropriate container
•70” high X 19” diameter.

op Bottom
•The top and bottom assembly of the secondary
separator needs to be mated, bolted and siliconed
together.
•A full seal is required to maintain constant
vacuum.
•The secondary separator will also have two ports
both 6” diameter.
•The 6” pipe heading out of the top of the
separator will have to be connected to the filter
housing.

4. Filter Housing
•The filter housing is the last component that the air stream flows through. It
protects the blower from any remaining product still in the air stream.
•Filters are washable and reusable. Please ensure the filter housing is mounted
in an easily accessible location, to allow
for maintenance.
•The filter housing consists of two parts
filter housing and basket, which easily
detach.
•To allow easy removal the basket
component must not be obstructed.
•31 – 3/8” high and 25 – 1/2” wide.
•The 6” port coming out of the top of the
filter housing will lead towards the blower
package.
5. Blower Package
•The blower package generates the suction
and pressure. It is built out of a heavy duty
steel frame.
•The base itself is 32” wide X 43 – 3/8 long (31
– 1/2” wide X 41 – 1/2” long for the 510
blower base).
•The blower package has a single 6” port
where the air stream is generated.
•The 6” pipe going into the blower comes from
the filter housing.
•The blower is a crucial part of the Central Vac
system and requires service.
•When installing ensure that the belt cover and
blower are assessable for service personnel

Piping Components
•Aluminum tubes
•4” aluminum tubing is the typical size of the main line of the Central Vac system.
•3” aluminum tubing is used for the drop lines, going down towards the camlock
inlets.
•In some applications the unit will be equipped with a 3” mainline and 2” drop
lines
•Galvanized steel elbows
•Used for corners in the piping
system.
•Available in 2”,3”,4”, and 6”
•6” elbows are utilized between
the blower, filter housing, and
separators.
•TY's are used to connect the
inlet piping going to the main
pipe line.
•Drop lines should never enter the main line from the bottom.
•TY's are directional and must be installed in accordance with the air flow.

•Compression Coupling
•These are used to join all the piping together.
They consist of a three bolt compression
clamp, black gasket, and a grounding strip.
•In order to fully function, the clamp must
be fully tightened for maximum clamping
force.
•Ground strip
is put into place in order to prevent static
electricity build up.
•Mounting Brackets
•The mounting brackets are mounted to the wall
or to any other solid support.
•The saddle clamps are attached to the
mounting brackets.
•Saddle Clamps
•Saddle clamps consist of two parts a
“saddle” and a u-bolt, and are used to
attach the piping system to mounting
brackets.
•Tighten the nuts evenly to prevent any incidents of piping separation or falling.

•ube Hangers
•Tube hangers are an effective way to hang the piping
system from the beams running along the roof.
•Consists of a Top Beam Clamp, a rod, and a hanger
properly sized to the piping.
•Rubber Flex Line
•Rubber flex line is used
on the suction end of the
central vac system, and
is used for by the
operator.
•Has a static wire built into it to prevent static electricity build up.
•If servicing a rubber hose, ensure that the ground wire is making contact with
the coupling.
•After the service, the installer must check the resistance by using an OHM
meter on the couplings while they are in contact with each other.
•The conductivity of the coupling should read between 0 and 5 ohms
resistance.
•Also available as a clear hose.

•Camlock Coupling
•The camlock couplings are used to connect
the piping to pickup hoses.
•They are designed for quick and easy connect
and release.
•A rubber seal is
installed in the
opening of the
coupling to ensure
proper connection and to prevent connection leaks.
•When installing a camlock coupling, be sure to
have a ring of silicone around the piping and have the coupler closed.
•Camlocks must be installed with dust plugs inserted to ensure gasket is not
pushed out by pipe
•After installing the coupler, attach the chain from the dust plug to the
Camlock coupling.
•This ensures that the dust cap will not be lost when an operator is using the
Central Vac system.

Piping Requirements
•Every system is different, built to suit the
customer.
•Typical system will include piping layout/ system
design drawings provided by either approved
project engineering staff or qualified Walinga
personnel.
•All piping installed must be properly supported.
•When installing the support points, ensure
that there is enough strength to support a full
pipe line, should the system become
plugged.
•One support point every 10' is
recommended.
•Ensure that the main lines are as straight as
possible to maintain maximum conveying rate.
•Space the inlets and the inlet piping, at a maximum of 40' apart. Or in accordance with
piping layout drawing provided.
•When installing the inlet lines, ensure that the Y elbows enter from either the side or
the top of the main pipe line. The Y must also follow the flow of the product and air
stream.
•All the piping should be within 400' of the main
Central Vac system to maintain product air
speed and avoid plugging
•All compression couplers must be fully tightened,
ensuring a proper seal.
•Grounding strip must be properly installed,
making contact to both pipes, to ensure total
protection from static electricity build up.

•As much as possible ensure that all joining components are easily accessible for any
future service and maintenance.
•Electro-Static hazard warning labels must be installed on the piping by all inlets.
•For ease in future maintenance, install all the compression couplings facing the same
way.

ypical System Design

Set Up Procedure
Every System is different!
1. Inspect the system design drawings,
compare with all the parts received.
2. Inspect all the locations of where the
components will be installed, look for:
(a) Proper support points.
(b) Obstructions
3. Starting at the Central Vac's main
components install and anchor the hanger
manifold.
4. Install the airlock and fasten it to the
hanger manifold.
5. Run a bead of silicone around the top lip
of the airlock,
and then
position the
primary separator with the 6” outlet port facing towards the
secondary separator.
6. Install the secondary separator.
(a) Ensure that silicone is applied between any of the
secondary separator parts.
7. Install the 6” pipe and 6” compression couplers in between
the separators.
8. Along the side of the hanger manifold, install the filter
housing.
(a) Install the filter inside the basket at the bottom of the
filter cannister.
9. Run the 6” piping along with the 6” elbows and 6”
compression couplers from the secondary separator, out
of the top, down to the inlet port on the side of the filter
housing.
10.Place the Blower package close to the hanger manifold
and run your 6” piping from the top of the filter housing to
the blower inlet.
11. Refer to the supplied system drawing to map out the
location of the piping.
12.When joining piping, ensure that the grounding strip is
present on all compression couplers. Do not leave gaps
between piping sections or between piping and elbows.
Gaps will lead to premature wear of piping and create
holes in couplers and gaskets.
13.For ease in maintenance install all compression couplings facing the same way.
(a) This created minimal movement when removing any couplings.
14.When installing the camlock couplings, ensure that the dust cap is installed and
clamped on, before applying silicone to the piping and installing the camlock coupling.

15.Install Electro-Static Hazard warning labels on the piping at all the pick up points.
16.Install the chain from the dust cap to the camlock couplings.
