4. INSTALLATION
This section describes the different installation methods (See section 4.1 to 4.3). Please refer to the GAD to identify
the installation method that is applicable to the purchased equipment.
The concrete construction shall be flat, level and plumb, and shall be in accordance to DIN 18202 or equivalent
ACI 117-06 standard (see Section 9). If necessary, use non-shrink grout in order to meet the specified standard.
The minimum concrete strength shall be 25 MPa (3,600 PSI).
The following procedures are general installation guidelines. Please refer to the notes on the GAD for specific
information about the installation method and the required materials (type, size and quantity of anchor bolts,
construction sealant, etc.). Always follow the anchor bolt and construction sealant manufacturers’ installation
instructions. Note that, typically, construction sealant requires dry concrete surfaces for its application.
Note that as standard, installation materials such as anchor bolts, hex-bolts and construction sealant are not
supplied with the equipment, unless otherwise specified.
4.1.EMBEDDED IN CONCRETE (IN THE CHANNEL RECESS)
Step 1: Initial assessment
Check that the concrete wall meets the requirements described in Section 4.
Verify that all installation materials specified on the GAD are available. Wooden wedges are used to center and
level the gate in the recess prior to embedding it in concrete. Optionally, the unit includes Side Centering Fittings
and Bottom Leveling Brackets which ease the positioning of the unit. In this case, hex-bolts are used.
Step 2: Frame alignment in the recess
Position and center the unit in the recess of the wall,
using wooden wedges (or field adjustment bolts if the
gate includes Side Centering Fittings and Bottom
Leveling Brackets).
Align the unit vertically and make sure that the
frame is flush with the invert of the channel. Adjust the
bolts on the "Bottom Leveling Brackets" if applicable
(See Figure 5).
Align the unit horizontally and make sure that the
Frame Guide is flush with the channel side wall.
Additionally, make sure that the gate is perpendicular
to the side walls of the channel. Adjust the bolts on the
“Lateral Centering Fittings” if applicable (see Figure
4).
Step 3: Frame embedment in the wall recess
Pour the second phase of concrete. Take special
care not to damage the seals.
Do not pour in more than one meter concrete
columns to avoid damage to the frame.

4.2.FACE MOUNTED (IN EXISTING CHANNEL WITHOUT RECCESSES)
Step 1: Initial assessment
Check that the concrete wall meets the requirements
described in Section 4.
Verify that all installation materials specified on the
GAD are available. Anchor bolts and grout are used
for this type of installation.
Step 2: Anchor the gate to the side of the channel
Position the unit in the existing channel. Make sure
that the gate is perfectly aligned and centered in the
channel (see Figure 6).
Install the bottom anchor bolts, and then the lateral
anchor bolts (see Figure 8). All Face Mounted Channel
Gates include lateral mounting
Figure 6
Figure 7
brackets. For smaller sizes (typically under 1500mm/ 60”), the channel gate includes lateral flexible brackets (as
seen in Figure 7) that require no field adjustment. For bigger sizes (typically above 1500mm/60”), the channel
gate includes “Field Adjustment Brackets”. In order to adjust the bracket, the following steps shall be followed (see
Figure 7):
oAdjust the bracket until it is completely leaning against the wall
oSecure the bracket with the nut and install the anchor bolt
Step 3: Grout fill
Grout-fill the remaining voids (See Figure 9), both at the bottom (See Figure 11) and laterals of the gate. Remember

IOM MANUAL
AG STOP GATE
SL STOP LOGS

EDITION 01/2017
IOM-AG-SL
that the objective of the grout fill is twofold:
oFill the voids between the frame, frame invert and the channel.
oMake a smooth transition for water flow.
CAUTION! Make sure not to get grout or any other foreign material on the gate’s seals, guides or stem as this may
cause leakage or damage.

4.3.WALL MOUNTED (AT THE END OF THE CHANNEL)
Step 1: Concrete construction inspection
Check that the concrete wall meets the requirements
described in Section 4.
Verify that all installation material specified on the GAD is
available. The equipment is installed by means of anchor
bolts. Construction sealant shall be used between the frame
and the concrete wall. Alternatively, sponge EPDM rubber can
be used.
Step 2: Equipment pre-installation
Present the unit to its required position and ensure that the
invert of the frame is flush with the civils. Also make sure that
the equipment is centered with respect to the channel opening
(See Figure 12).
Drill and install one anchor bolt on each side of the frame
(See Figure 13). After installing the first anchor bolt, and prior
to drilling the hole on the other side, make sure the frame is
perfectly leveled.
Step 3: Construction sealant application
Remove the unit from the wall (first remove the nuts of the
anchor bolts).
Apply construction sealant all around the perimeter of the
frame. Be sure not to get sealant on the gate’s seals and/or
guides, as this may cause leakage or damage. (See Figure
14).
Re-install the slide gate on the wall and tighten both anchor
bolts.
Step 4: Final installation
Drill and install the rest of the anchor bolts (see Figure 15).
CAUTION! If the unit is not completely in contact with the
wall, do not over-tighten the anchor bolts. Over tightening
may bend or distort the frame. If the wall flatness and
levelness is according to the specified standards, the
construction sealant will fill in the remaining voids (see Figure
16).
Apply construction sealant around the frame perimeter in
order to fill in any existing gap between the wall and the
frame (200ml/meter) Wipe away the excess sealant to leave a
smooth finish.

5. START-UP AND COMMISSIONING
Do not operate the gate unless it is completely necessary. Typically the plant (i.e.: waste water treatment plant) has
not been finished when the commissioning occurs. Therefore, dust and dirt tends to accumulate on the seals and
stems. Do not apply extra grease on the seal and/or stem until the construction of the plant has been completely
finished as it forms a sticky paste with the dust. If the equipment needs to be operated previously wet the seals.
Clean the unit with clear water and make sure there are no foreign deposits or materials on the seals, guides or
sealing area. Use plastic tools to remove any foreign material in order not to contaminate the stainless steel
equipment.
Visual Inspection
Verify that all installation instructions defined in the GAD and the IOM manual have been followed.
Verify that the seal is in compression against the frame (or logs in case of SA aluminum stop logs). Use a 0.5mm
(1/32”) gauge.
Embedded In concrete installation:
oCheck that the frame (or other embedded parts) has not been distorted during installation. Measure the
opening width every 1 meter. The maximum deviation should be +-width/1000.
oVerify that the frame invert has been embedded in concrete.
Wall mounted at the end of the channel installation. Verify that there are no voids between the concrete wall and
the back of the frame (open the gate and look on the sides). No light must go through the frame and the wall. Clean
water can also be used to verify water tightness between the concrete wall and frame.
Face mounted in existing channel installation:
oCheck that the frame has not been distorted during installation. Measure the opening width every 1 meter.
The maximum deviation should be +-width/1000.
oCheck that the frame has been grouted as indicated in the GAD
Field Operational Test:
Before cycling the unit, make sure there are no foreign deposits or materials on the seals, guides or sealing area.
Clean the unit with clear water. Gate seals could be damaged if the area is not cleaned and coated with grease.
Please refer to Section 7.1 for detailed information.
Seals shall be wetted with clear water before operating the slide gate, and stems and stem nuts shall be greased.
Field Leakage Test
Close the slide and pressurize the unit at the design water head.
Collect the leaked water during a period of time of 10 minutes (LT10)
Calculate the leakage rate: LR(L/min and m) = LT10/(10*P), where P is the sealing perimeter in meters.

6. OPERATION
Seals shall be wet while operating. If the slide gate has not been used for a long period of time under dry
conditions, the seals shall be wetted with clear water before operating the slide gate. Operating the gate with dry
seals may damage them, and additional thrust might be required to operate the slide. Please refer to section 7.1 for
detailed information about the required grease type.
The following equipment can be used to lift up the gate or logs:
oHand-pull: the slide or logs are equipped with handles. ORBINOX recommends the use of other methods
for pull out forces higher tan 50kg [110 pounds], or 25kg per person [55 pounds]. Refer to the GAD for
pull out force detailed information. Hand poles can be supplied for remote operation.
oExternal crane: the slide or logs are equipped with bull eyes to be lifted with an external crane.
Optionally, a lifting device (beam) can be supplied.
