2. INSTALLATION
This section describes the different installation methods:
•First, the slide gate is installed (wall mounted, concrete wall mounted, round manhole mounted, or wall
thimble mounted)
•Once the gate is installed, stem Extension, stem guides and floor stand must be installed
2.1. Slide Gate installation
▶Required Materials:
•ORBINOX MU slide gates are installed by means of Anchor Bolts. Depending on the size and working
conditions they shall be either of the mechanical or chemical type. In order to get the expected
performance of the anchor bolts, the minimum concrete strength shall be 25Mpa (3,625 PSI)
•In order to avoid leakage between the concrete wall and the frame construction sealant shall be used.
(Sikabond or Sikaflex 11FC Sealant or equivalent, 200ml per meter of opening perimeter). As an
alternative, self-adhesive commercial sponge EPDM strips, approximately 20mm/0,80” wide by
10mm/0,40” thick, can be used and glued to the slide gate around the hole
•For detailed information about the type, size and quantity of the required anchor bolts, or any other
specific installation notes or materials, please refer to the notes on the ‘General Arrangement Drawing’
▶Installation procedure:
Step 1: Concrete wall surface check
•The concrete construction shall be flat, level and plumb, and shall be in accordance to DIN 18202 or
ACI 117-06 standards (see section 6). If necessary, use non-shrink grout in order to meet the specified
standard
•Concrete wall surface shall be dry (so the construction sealant sets effectively). If it is necessary. the
wall can be dried with the help of a blowtorch or a hot air fan
Step 2: Reference lines
•Reference lines shall be marked on the wall
in order to assure a proper alignment
between the slide gate and the opening
during the installation:
• Measure the top width of the frame (“d”)
and mark a horizontal line on the wall (RL-
1), parallel to the opening and to the
measured distance
• Mark a vertical line on the vertical
symmetry axis of the opening (RL-2)

Step 3: Pre-installation of the slide gate
•Place the slide gate against the wall and line up
with the opening. Use previously marked
reference lines for proper alignment. The gate
shall be in the closed position
•Drill and install an anchor bolt on each side of
the gate. After installing the first anchor bolt, and
prior to drilling the hole on the other side, make
sure the frame is perfectly levelled
Figure 2
Step 4: Construction sealant application
In order to avoid leakage between the frame and
the wall, construction sealant shall be applied
on the frame:
•Remove the slide gate from the wall (first remove
the nuts of the anchor bolts)
•Apply construction sealant all around the
perimeter of the frame. Sikabond or Sikaflex
11FC (200 ml/m) or equivalent construction
sealant shall be used. Be sure not to get sealant
on the gate’s seals, guides, and/or stem, as this
may cause leakage or damage
Figure 3
Step 5: Final installation of the slide gate
•Re-install the slide gate on the wall and tighten
both anchor bolts
•Drill and install the rest of the anchor bolts (see
Figure 4)
•CAUTION!: If the slide gate 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 void
(see Figure 5)
•Apply construction sealant around the frame in
order to fill in any existing gap between the wall
and the frame (this step is only for esthetics).
Wipe away the excess sealant to leave a smooth
finish

2.2. Installation: concrete wall mounted
▶ Required Materials:
•Some slide gates require installation type embedded in concrete, mainly when working with unseating
pressure and/or large opening sizes
•The civil work shall be prepared to fit the slide gate (see Figure 6). Appropriate recesses are required for
the frame (Refer to the GAD for dimensional information)
•The concrete wall thickness shall be designed to withstand the loads defined in the GAD. In addition, the
civils must have a predetermined height (see the GAD) in order to be able to fix the slide gate on top of
it. In order to effectively transmit the loads from the frame to the concrete, ORBINOX recommends welding
the existing rebar to the frame ribs prior to pouring the second phase of concrete. It is not ORBINOX’s
responsibility to specify the required wall thickness and to define the amount of rebar to be welded
•To fix the slide gate and prevent it from moving during Second Phase of concrete, mechanical anchors
are required. 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.)
Figure 6
▶ Installation procedure:
Step 1: Concrete wall surface check
•The concrete construction shall be flat, level and plumb, and shall be in accordance to DIN 18202 or ACI
117-06 (see section 6). If necessary, use non-shrink grout in order to meet the specified standard
•It is necessary the presence of work rebar in the wall recess (to be able to weld the frame to the rebar).
Alternatively, chemical anchors can be installed

Step 2: Level and secure the slide gate in place
•Present the slide gate in position in front of the
wall opening (using a crane). If the thickness of
the civils is correct, install the upper levelling
brackets. If it is not possible, continue handling
the gate with a crane
•Apply construction sealant at the back side of the
frame. Use elastic sealant Sikabond or Sikaflex
11FC (200 ml/m) or equivalent
•Align the gate vertically adjusting the levelling
bolts, placed in the invert of the frame (see Figure 7)
•Place the lintel completely on the wall and make
sure that the slide gate is aligned vertically
•Present the slide gate to its required position:
oAdjust beforehand and install the bottom
levelling brackets against the floor using
mechanical anchors
oFix the lintel by means of two mechanical
anchors
oInstall the chemical anchors of the lintel
oWeld the frame to the existing rebar

3. OPERATION
Initial Operation:
Before cycling the slide gate, make sure there are no foreign deposits or materials on the seals, guides or
sealing area. Gate seals could be damaged if the area is not cleaned and coated with a light grease. Please
refer to section “ Materials needed for maintenance and seal replacement ”for detailed information about
the grease type (see section 4.1)
•Manual
Apply a light grease on the stem before initial operation after the installation. If the operation is difficult
due to high torque, stop operation of the gate and check stem alignment
•Electric actuator
oRefer to the electric actuator manufacturer instruction manual before commissioning the slide gate
oElectric actuators must be limited with limit and torque switches. Electric actuators without these limiters
shall not be used with ORBINOX slide gates. Electric actuators must be adjusted at the time of
installation on site (except in the case of a self-contained frame and yoke-mounted actuators; in this
case the motor is factory-set). To adjust the limit switches, follow the next instructions using values of
the GAD:
•Position the slide in the nearly closed position (leave 10mm/0,40” open). From this position,
manually (using the handwheel) operate the slide until it is completely closed (check tightness with
a 0,05mm/0,002” gauge). In this position, set the limit switch for the CLOSED position
•Position the slide in the nearly open position (leave 10mm/0,40” closed). From this position,
manually (using the handwheel) operate the slide until it is completely open. In this position, set
the limit switch for the OPEN position
oBe aware when the gate is almost fully OPEN or CLOSED. If the gate does not stop once the fully
open or fully closed position is reached, stop immediately and correct adjusting again the limit and
torque switches
Operation:
•CAUTION! Do not force the operator to close the gate, as it may cause damage to the stem and it does
not improve the sealing system. The maximum applicable force on the handwheel is 25 kg /55 lbs
•The MU slide gate is closed by a clockwise rotation, and opened by a counter-clockwise rotation of the
operator
•The mechanical limit switch for the OPEN position is operated by a mechanical stop on the side of
frame. For some gates with open frames, the limit switch is made by means of the first wall bracket (see
the GAD)
•The MU slide gate is designed to be self-locking, so that the slide maintains its position in any position

4. MAINTENANCE
4.1. Cleaning and lubrication
ORBINOX model MU slide gates need practically no maintenance. In order to assure maximum
performance of the slide gate, the following maintenance inspections shall be carried out periodically
every 6 months:
•Stem and stem nut shall be cleaned and greased. For non-rising stem configurations, the stem may be
in contact with water and dirt. Under these conditions, the threads of the stem and/or stem nut may to
wear, and they shall be checked every 3 months
•Clean the gate with clear water and remove any deposits, especially on the seals and in the guides
•Check the seals and make sure they are not damaged. Seals shall be replaced if damaged (See sections
4.2, 4.3, 4.4, 4.5, 4.6 y 4.7)
•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. If the slide
gate is operated with dry seals, a higher operating torque will be required, and the seals may be
damaged
Spare parts:
ORBINOX does not recommend stocking any spare parts by the owner of the equipment as the slide
gates are designed for a very long life cycle. If a repair part is required, please contact an ORBINOX
representative and provide the following information:
•ORBINOX S/O number
•“ORBINOX General Arrangement Drawing” number
•Project name (if applicable)
