1. GENERAL
1.1 Safety
Prior to any work or start-up and in order to ensure a proper functioning of our
products,
the instruction manual for installation and operation must be observed.
Alterations on the products need our written approval. For consequential damages
due to neglect of this direction, any liability will be rejected.
This symbol marks safety and risk advice. Follow all such advice in order to prevent any
damages to human life and objects.
This symbol refers to important information.
The installation must be carried out according to established procedures and only by
qualified personnel.
Project related data of valves, e.g. dimensions, materials and service range are found
in the respective documentation.
1.2 Designated service
The WEY®sluice gate is used in drain channels and basins at sewage treatment
plants and retaining reservoirs.
The sluice gate is suitable to shut-off pressure containing systems for water and
sewage. The technical application limits referred to in the relevant project data
documentation and this maintenance manual must be observed.
Should the WEY® sluice gate be installed in a explosive environment, the valve as
non-electrical equipment, as well electrical equipment must be conform to RL
94/9EG, ATEX.
2. TRANSPORTATION, STORAGE
2.1 Transportation
The transportation of sluice gates shall take place in a careful way. Lifting devices
shall not be hooked onto stems nor other actuating components. Sluice gates shall be
placed on even surface only, never tilted onto an edge, to prevent distortion of the
frame. The equipment shall be protected against exterior damage and atmospheric
exposure.
Large equipment will be supplied with additional transportation supports. These
supports shall not be removed before final mounting.

2.2 Storage
Until final installation the equipment shall be stored in a dry, vented area. All function
relevant parts shall be suitably covered against humidity, dust or other contamination.
For longer storage periods or in case of unfavourable storage conditions which could
affect later the proper functioning, all blank surfaces, e.g. stem, piston rod shall be
suitably protected by long term preservatives against corrosion.
Factory applied preservatives shall be checked for possible transport damages and
appropriately repaired, if necessary.
For mounted accessories such as electric actuators, limit switches, solenoids, etc.,
the
3. INSTALLATION
3.1 Preparation before installation
Onsite construction work details, recesses, walls, etc. shall be checked for accuracy,
flatness, finish, etc. before starting with mounting the equipment.
Dimensions of any recesses have to comply with manufacturer’s drawings and shall
be checked acc. Fig. 1 and Fig. 2.
The walls shall be checked with plumb and level for its perpendicular (fixation of
frame, stem guides and actuating components) as well as its horizontal and vertical
flatness.
Fig. 1 Fig. 2
Larger deviations must be corrected on site prior to mounting, as follows:
a) by grinding, removal, equalizing of uneven surface;
b) by applying concrete filler according to requirements (tightness, strength).

3.2 Mounting aids
In order to offset construction discrepancies, plastic or stainless steel shims or spacer
plates in various thickness may be used to level and position the fixing frame, wall
bracket and actuating components. Minor discrepancies can be compensated that
way. The frame gets therewith enough wall support that it cannot be distorted when
tightening the fixing bolts.
Major discrepancies must be compensated with threaded rods of suitable size if
assigned bolts
are too short (bad concrete quality, anchor hole too long or if many spacer plates had
to be used). Cut to size threaded rods must be inserted and tightened with 2 nuts.
After tightening the counter nuts must be removed and the threaded rod can be used
in replacement of a short bolt.
To seal between frame and wall, paste type, medium resistant sealants are most
suitable.
If filler or sealant is used, observe manufacturer’s instructions with priority.
3.3 Sluice gate with fixing clamps
Mounting and embedding work shall take place with sluice gate in completely closed
position only. For best sealing between wall and frame, the wall construction must be
dry.
Procedure
- Position sluice gate in the respective recess or in front of the wall opening to
shut-off and align with plumb and level, acc. Fig. 3.
- Drill anchor bolt holes at the transverse seal which serve as mounting aids.
- Set both anchor bolts and tighten them temporarily.
- With the set screws at the transverse seal (see Fig. 6) the required compression
of the seal against the gate can be adjusted. The adjustment shall be in a way
that an optimal compression of the sealing lips is reached.

- Check alignment with plumb and level. Readjust position of sluice gate, if
necessary.
Upper level of bottom profile must comply with finished floor level according to site
plan.
- Drill and set remaining dowels for all clamps, according supplier's specification.
- Prior to final fixation, pull frame slightly away from the wall in order to place two
rows of sealant (according supplier's instructions) behind the frame and
transverse seal up to the max. height of water head, respectively to the
transverse seal (Fig. 4 and 6). If bottom seal is bolted, sealant shall also be
placed there.
- All bolts can then be firmly tightened with the torque key, according to the
product/
supplier's specification, starting at the transverse seal and afterwards the
clamps.
Further information is found on the relevant project drawings.

- When tightening the bolts, the sealant gets squeezed out on both sides of the
frame. Smoothen sealant with finger to a clean grout (Fig. 5).
- For sluice gates with transverse seal an additional grout is necessary after
tightening between wall and transverse seal acc. Fig. 7.
- After mounting the actuating components (acc. 3.4) the sluice gate shall be
opened and the sealant on the inside of the frame and transverse seal shall be
smoothened to a clean grout acc. Fig. 5 and Fig. 7.
- The bottom profile, if existent, requires onsite embedding with filler or mortar acc.
Fig. 8.
When filling these recesses never use any vibrators !
ottom and transverse seal profile shall be free of any concrete or other contamination.B

3.4 Sluice gate with anchor bolts for embedding
Mounting and embedding work shall take place with gate in completely closed position
only.
Procedure
- Position sluice gate in respective recess and align with plumb and level acc.
Fig. 9.
- Depending on size and weight of sluice gate, 2-3 dowels per side should be set
into
the recess and bolts be inserted (Fig.10).
- If supplied with transverse seal, set bolts and seal thereafter, as described in
3.2.
- Align sluice gate with plumb and level and fix frame.
- If necessary, tighten bolts at the transverse seal.
- Connect anchor and dowel bolts in the recess with a bar profile by welding acc.
Fig. 10.
Always position sluice gate with mounting aids of steel, never use wood wedges.
Sluice gate must never be weld-connected to concrete reinforcement bars.
- Check alignment with plumb and level. Realign sluice gate, if necessary.

3.5 Actuating components
Sluice gates with separately supplied actuating components, must not be actuated prior
to embedding.
Fig. 11
Procedure:
- Extension rod with coupling to be pinned to the bare shaft of the stem. For
coupling procedure keep wall bracket loose on the extension rod.
- Align coupled extension rod with plumb and level acc. Fig. 11.
- Position wall brackets and drill holes.
- Check alignment of all components with plumb and level. Realign if necessary,
using suitable shims.
- For additional supports, floor stands etc., appropriate positioning and alignment
is required before drilling holes.
- Set dowels and bolts.
- Check alignment of all components with plumb and level. Realign if necessary,
using suitable shims.
- Mount and fix all actuating components.
