FINAL CHECKLIST

Compact Plus Primary Cleaner 5 25/06/2020
SECTION 1 - SAFETY
The Compact Plus Primary Conveyor Belt Cleaner is designed to be quickly and easily
serviced by appropriate personnel. If appropriate safe visual access is provided, inspection
and tensioning adjustments can be carried out whilst the belt is in operation.
However, under no circumstances should servicing or installation of the cleaner be carried
out whilst the belt is in operation.
The conveyor must be shut down and locked out before any person enters or reaches into
the chute or conveyor enclosure.

Compact Plus Primary Cleaner 6 25/06/2020
SECTION 2 - INTRODUCTION
The Compact Plus is a conveyor belt Primary Cleaner, designed for use on smaller
conveyors where space is often restricted. The Compact Plus is suitable for use on conveyor
belts that range from 200 to 1200 mm wide, and where belt speed is low to moderate.
The patented CARP-2 blade design will provide excellent cleaning performance and long
wear life under a range of conditions. Blade materials are available to suit most bulk materials
handled.
The Compact Plus Primary Cleaner is normally mounted on the face of the conveyor head
pulley and is designed to peel off the thick layer of loosely adhering material that often
accounts for 80%-90% of carryback.
The Compact Plus is normally used in conjunction with at least one secondary cleaner, such
as the ESS Compact Secondary, and often with a water spray system.
The segmented cleaning blades are of cast Urethane, and can be easily removed by sliding
on and off the mainframe track for replacement when worn.
Important points to remember concerning the Compact Plus are:
1. The cleaner is directional - it will only clean a belt travelling in the design direction -
however, the cleaner will not be damaged or affected by belt direction reversal.
2. The cleaner is suitable for use on crowned head pulleys and damaged or grooved
belts. The urethane blades quickly conform to the belt profile.
3. For slow moving belts, the cleaner should be positioned lower on the head pulley to
ensure the blades are clear of the main material flow.
4. The cleaner requires an access point in the conveyor chute to install and replace the
urethane blades. This should be in the form of a covered door of sufficient size to
allow a technician to reach in and recover the blades. The access door should comply
with all current conveyor and safety regulations.

Compact Plus Primary Cleaner 7 25/06/2020
SECTION 3 - PREPARATION FOR INSTALLATION
1. CHECK INSTALLATION DRAWINGS - Ensure that you have the correct
drawings and equipment for your conveyor(s).
2. PRE-ASSEMBLE THE CLEANER(S) AND MOUNTS -Do this in your
workshop or similar free area, rather than at the Conveyor. This will enable you to:
verify all required equipment is present
familiarise yourself with the cleaner assembly
allow you to plan the installation, reducing installation time.
3. ASSEMBLE THE NECESSARY TOOLS & SAFETY EQUIPMENT
REQUIRED FOR THE INSTALLATION
4. OBSERVE THE CONVEYOR WHILE RUNNING AND CONVEYING
MATERIAL -
Observe the material trajectory
Observe the belt direction - does it reverse or roll back?
Observe the belt splice condition
Does the belt run true, or track off to one side?
Is the Head Pulley out-of-round?
Consult ESS if any UNUSUAL conditions are observed in the above. These conditions may
result in recommendation of a different installation position or even a different cleaner.

Compact Plus Primary Cleaner 8 25/06/2020
SECTION 4 - INSTALLATION
DANGER
Conveyor must be shut down and locked out before any installation or service work is
performed.
WARNING
Thoroughly assess the job and jobsite before proceeding. Ensure that personnel and
equipment are protected from injury or damage during installation.
ESS recommends that a Job Safety Analysis (JSA) be conducted before proceeding
with any installation work.
4.1 INSTALLATION OF COMPACT PLUS MAINFRAME
Step 1 - Locate the Centre-line of the Compact Plus Cleaner Mainframe
Using the typical installation drawing supplied in this manual, locate the mainframe’s centre-
line on both sides of the conveyor chute. For conveyors that do not have an enclosed chute,
fabricate suitable mounting plates each side of the conveyor, or contact ESS for assistance.
Measure radially Amm (see table following) from the face of the belt. From this point draw
an arc using the pulley’s centre-line as the centre point. The centre-line of the mainframe
can be located anywhere along the radius as long as the blade does not lie in the material’s
trajectory.
For faster belts, the blade tip should contact the belt near or just below the horizontal
centre line of the head pulley.
For slower moving belts, lower the cleaner until the tip of the blade clears the material
trajectory.
Do not place the cleaner lower on the head pulley than necessary, as this will cause
the blade to lay flat and allow accumulation of material.
Avoid placing the tip of the cleaner above the horizontal centre line of the pulley, as
exposure to excessive amounts of material will result in low cleaning performance and
high blade wear rates.
Ensure that the mainframe is in the same position both sides of the belt –that is, the
cleaner is parallel and level to the belt face and head pulley.

Step 2 - Verify Mainframe Position Before Proceeding
Position the tensioner and mount assembly over the centre-line marks for the mainframe.
Verify that the mounts fit, and that adequate room is available to tension the cleaner. If
mounts or tensioner interfere with structural members, it may be necessary to locate the
cleaner elsewhere on the A mm offset radius, but first remember these points:
The mount can be rotated to any angle.
The tensioner can be reverse assembled, as long as it is tensioning the blades in the
correct direction –see diagram below.
The tensioner assembly may be located on the opposite side of the conveyor, as long
as access is available for maintenance.
Once mounting position is confirmed, proceed.

Compact Plus Primary Cleaner 10 25/06/2020
Mount and Tensioner assembly can be rotated to any angle and reverse assembled for
tensioning in either direction.
Step 3
If the cleaner mounts are to be mounted to the chute wall cut a hole Ø70 at the selected
mainframe mounting positions each side of the chute. Mark out and drill bolt holes as shown
below. If the mount is to be rotated as described above, remember to rotate the bolt hole
pattern to the same angle.
If the mount is to be attached to structure or brackets other than the chute wall, project the
line of the mainframe centre to the mounting position, and provide cutouts and bolt holes at
that position.

Compact Plus Primary Cleaner 11 25/06/2020
Step 4
Remove the blades from the mainframe by first loosening and removing the blade locks.
Insert the bare cleaner mainframe through the cutouts in the chute wall. Slide the tensioner
side and far side mounts onto the pipe ends of the mainframe and loosely bolt the mounts to
the chute walls with the mainframe in the pre-selected position. Do not secure the tensioner
lockscrews to the mainframe.
Does the centre-line of the mainframe lie A mm from the belt face? (The Compact
Plus installation gauge is available to assist in checking this dimension).
Is the mainframe level or equal to the pulley shaft?
Step 5
Remove the far side mount bush, then slide the mainframe to the far (non tensioner) side
until the tensioner end of the mainframe is clear of the inside of the chute.
Inside the chute or conveyor enclosure, slide a blade retainer onto the mainframe, followed
by the required number of blades, and a second blade retainer. Ensure the blades are facing
in the correct direction.
Slide the mainframe back through the tensioner side mount, and re-fit the mount bushes.
Centre the blades on the mainframe, then tighten the blade retainers in place against either
side of the blades. Rotate the mainframe until the blade tips lightly contact the belt.
Do the blade tips all touch the belt at the same time? (+1mm)?

Compact Plus Primary Cleaner 12 25/06/2020
NOTES
Slight inconsistencies in the belt thickness and blade shape, accounting for small gaps
between blade and belt, will quickly be taken up by blade flexure on tensioning.
For crowned head pulleys, ensure that the outside blades on each side are an equal
distance from the belt whilst the centre blade is touching. Again, these gaps will
quickly close on tensioning.
If any questions above have been answered “NO”, take appropriate action to correct the
installation. If all questions are answered “YES”, proceed.
Step 6
Securely bolt the cleaner mounts and brackets to the chute wall or structure. If not already
done, fit and secure the tensioner components in place as shown previously. Ensure that the
tensioner is operating in the correct direction. If not, reverse the tensioner assembly to
achieve the correct direction.
4.2 SETUP AND ADJUSTMENT OF THE SPRING TENSIONER
The Compact Plus Primary Cleaner is supplied with a pair of steel mount plates fitted with
low friction bushes. These mounts may be secured to the conveyor chute in any orientation
(horizontal, vertical or inclined), to suit site restrictions.
Remember, however, that the tensioner assembly also attaches to the mount, and that the
tensioner assembly must also clear site restrictions –see previous section.
The Compact Plus Spring Tensioner is a simple, robust and reliable tensioning unit. It can be
assembled to tension in either the clockwise or anti-clockwise direction and has two mounting
positions for each direction.
4.2.1 Assembly of the Spring Tensioner Unit
The Compact Plus Spring Tensioner attaches to the cleaner mount by utilising two of the
mounting bolts. Ensure that the low friction bush is in place in the mounts before proceeding.
Assembly of the tensioner is as follows:
Select the tensioning direction required –see diagrams in the installation section.
Remove the appropriate mounting bolts from the tensioner side mount, and fit the
pivot bracket, again ensuring that the bracket is positioned for the tensioning direction.
Bolt the pivot bracket in place. Note: Cast mounts used on later models will have a
gusset on one side of the raised hub. This is used on the Far Side mount only, and
has no use in the tensioner assembly.
Slide the eye end of the adjusting rod over the pin on the pivot bracket and and secure
with the split pin.
Insert the threaded end of the adjusting rod into the slotted hole of the operating arm,
ensuring the the arm is correctly orientated. Slide the operating arm down the
adjusting rod, then manoeuvre the hub of the operating arm over the end of the
mainframe.

Compact Plus Primary Cleaner 13 25/06/2020
Fit the spring over the threaded end of the adjusting rod, then fit the washer and
adjusting nut, only a few turns. Loosley fit the locking nut.
Check that the cleaner and blades are centred to the belt, then rotate the mainframe
until the blades are touching the belt. Position the operating arm so that the hub is
within 1 - 2 mm of the mount and the tail is extended against the spring. Secure the
lockscrews in the operating hub onto the mainframe.
By hand, turn the adjusting nut on the Adjusting Rod to bring the cleaner blade tips
into light contact with the belt.
The tensioner side is now fitted and ready for adjustment. Fit the far side lock collar
before proceeding.
4.2.2 Assembly of the Far Side Mount and Lock Collar.
The Far Side Lock Collar acts to prevent axial movement of the cleaner mainframe, but with
the ESS Compact Plus cleaner, it also doubles as a wear indicator and limiter.
Assembly is as follows:
Install the Far Side mount as previously described.
Slide the Lock Collar onto the Compact Plus mainframe, with the tab pointing inwards
toward the mount.
With the cleaner blades just touching the belt, as previously described, position the
Lock Collar tab at 30° to the mount gusset, in the opposite direction to the tensioning
direction. For a clockwise tensioning cleaner, place the tab at 30° to the anticlockwise
side of the gusset, and vice versa. Later model cast mounts will have indicator lines at
10°, 20° and 30°.
With the tab at 30°, and the Lock Collar approximately 1 - 2 mm clear of the mount,
tighten the lockscrews on the Lock Collar to secure the collar to the mainframe.
As the cleaner blades wear, the Lock Collar tab will move toward the mount gusset,
indicating the blade wear. The blades have approximately 30° of wear rotation, so the
tab will contact the gusset, indicating blade replacement is required, and preventing
further adjustment or wear of the blades.
4.2.3 Adjustment of the Spring Tensioner
The Spring Tensioner is adjusted by simply turning the adjusting nut until the spring is
compressed to the length indicated on the table below. Once the correct spring compression
is achieved for the belt width, secure the tensioner by tightening the lock nut against the
adjusting nut.

SECTION 5 - OPERATOR TRAINING
The decision to purchase ESS cleaning equipment has put within easy reach the reality of a
clean plant. The next step is the correct training of personnel to maintain and service the
equipment or contract ESS to maintain the cleaners so that they remain at optimum
efficiency.
The benefits of efficient cleaners outweigh the cost of maintaining the cleaners many times.
If you wish to have your cleaning system maintained on a regular contract basis, contact
ESS. If not, train your own personnel as follows:
1. Adhere to all local safety rules.
2. Give a “Hands On” instruction with the conveyor system shut down.
3. Give a “Hands On” instruction with the conveyor system running.
4. All service should be recorded in the plant maintenance log or database.
5. Encourage the person being trained to look for possible problems developing on the
system, eg. belt tracking excessively, tears or damage to belt, seized idlers, missing
bolts, etc.
A warning to the maintenance department to rectify small problems can save major
costs later in repairs and lost production.
6. Impress how important it is to maintain and service the cleaners correctly.

Compact Plus Primary Cleaner 17 25/06/2020
SECTION 6 - ROUTINE MAINTENANCE AND SERVICE
Regular inspection and servicing is the key to effective conveyor belt cleaning. It is
recommended that the cleaner be inspected once per week. Actual service intervals will vary
considerably from plant to plant.
CAUTION! DO NOT REACH INSIDE THE CONVEYOR CHUTE UNDER ANY
CIRCUMSTANCES WHILST THE CONVEYOR IS RUNNING.
ROUTINE INSPECTION / TENSION:
Step 1 Inspect the condition of the cleaner. Open the inspection door (if fitted) and
observe the condition and action of the blades and cleaner.
Step 2 If necessary (and if plant rules allow it), hose any material build-up from the blades
or mainframe - DO NOT REACH INTO THE CHUTE WHILST CONVEYOR IS
RUNNING.
Step 3 If necessary, re-tension the cleaner - refer to Section 4.
IF BLADE SERVICING IS REQUIRED:
Thoroughly assess the job and jobsite before proceeding. Ensure that personnel and
equipment are protected from injury or damage during maintenance.
ESS recommends that a Job Safety Analysis (JSA) be conducted before proceeding
with any installation or service work to identify and control hazards.
Step 1 Shut down and lock out the conveyor.
Step 2 Release the tension and back the blades away from the belt. Sharply rap the
blades against the belt to dislodge any build-up.
Visually inspect the blades.
If blades are clean, and not excessively worn, re-tension the cleaner.
If material build-up is still present or blades are excessively worn, proceed.
Step 3 Release the lockscrews securing the tensioner operating arm to the mainframe.
Open the access door or hatch, reach in and release the lockscrews on the two
blade retainers. Withdraw the mainframe through the Far Side mount until the first
blade retainer and then the blades can be removed from the mainframe inside the
chute.
Step 4 Clean and inspect the blades - if blades are fully worn, irregularly worn, or
otherwise damaged, replace with new blades.

Compact Plus Primary Cleaner 18 25/06/2020
Step 5 Re-install blades onto mainframe, followed by blade retainer, and reposition the
mainframe through the Tensioner Side mount and tensioner. Re-centre the blades
and retainers, and secure the retainers as previously described. Re-adjust the
cleaner as previously described in section 4.
Step 6 Remove locks or tags and restart belt. Observe cleaner action and blade
effectiveness. Replace access door or hatch - if fitted. Clean up work area.

Compact Plus Primary Cleaner 19 25/06/2020
