INSTALLATION MANUAL ZHJS + ZHJC
INSTALLATION OF ZHJS + ZHJCFOOT ASSEMBLY
This guideline describes how to install the ZHJS + ZHJCfoot
assembly onto the machine or component for which it is intended
to support.
0a. Prior to installation of the foot ensure that the incline
of the oor area intended to support the foot pad
does not exceed 10 degrees relative to horisontal.
0b. Assure that the foot pad will not span over cracks,
grout lines or other oor imperfections when
mounted. If unavoidable the cavity between the
load bearing foot and the oor must be sealed with
injecting bonding material under and around the edge
of the load bearing foot.
1a. Lift/Jack up the machine for free access to mount
foot assembly.
1b. Ensure that sealing is correctly mounted on top of
the sleeve. Grease external thread with FoodLube
Universal Grease. Make sure to remove any excess of
grease from external surfaces after installation.
2. Mount the machine foot on the machine and use a
wrench to adjust the vertical position. Make sure not
to exceed the max adjustable height and that the
length of engagement is correct.
Complete step 0-2 for all feet supporting the machine.
Lower the machine so that the feet rest on the floor.
Perform height adjustment if needed and ensure that
the machine is placed corretly and levelled
horizontally.
3. Use a wrench to rotate and tighten the sleeve up
against the bottom of the machine or component for
which the foot is used. Make sure that the sleeve is
properly tightened to secure the foot assembly and to
prevent dirt from accessing the thread.
NB. If the sleeve does not cover the thread, the leg is not
correctly installed and will neither meet hygienic
guidelines nor load specications.

4. Use a pencil to mark where the fixation holes should be
drilled.
5. The machine needs to be moved while the holes are
drilled. Once the machine is moved, remove all dirt and
bacteria from the floor - be sure not to remove pencil marks.
NB. For foot sizes Ø105, Ø125 & Ø150, the fixation holes can
be made by drilling through the holes in the foot plate.
Movement of the machine is redundant for these three foot
sizes.
6. Drill the holes for fixation of machine feet. Use the
anchoring plate to hold the drill in a 3o angle so that it fits the
direction of the fixing hole in the levelling foot.
7. The machine is placed back into the correct position -
make sure to place the machine feet so that they match the
position of the fixation holes.
8. Fill the fixation hole with mortar and add the anchoring
rod. When an expanding anchor is used make sure to follow
the manufacturer's instructions.
9. Allow the mortar to dry according to the manufacturer's
instructions and add the prescribed certified hygienic nuts
using a maximum torque of 10-12 Nm.
10.Repeat step 3 and make sure that the sleeve is properly
tightened to secure the foot assembly and to prevent dirt from
accessing the thread. The machine feet are now installed.

BEST PRACTICES
POSITIONING OF LEGS UNDER A MACHINE
For the optimal positioning of the machine, the machine feet
must be positioned in accordance with a few guidelines.
Level
The machine must be level
Even load
If the weight of the
machine is not distributed
evenly, the machine feet
should be placed as
illustrated.
Leveling
In order of achieving the
highest level of stability
the machine feet should be
adjusted as illustrated
(adjust with the same
amount of tension on each
foot)
Sloping floor
For a stabile result the
maximum slope of the
floor may not exceed the
recommendations for the
specific foot.
Max slope
Exceeded
Max slope
