Introduction

The following Installation Guide is designed to provide Watch Technologies’ customers with sufficient information to successfully install our gates as designed.

Typically, our customers were provided both Shop Drawings and a 3-‐D

CAD

model of their gates prior to manufacture for both review and authorization to manufacture.

If that was not the case please contact our office and secure these documents.

These documents alone, however, may not provide the all the guidance everyone may require to place their gates into position and secure them for the long-‐term.

This Guide will clearly define how Watch Technologies’ staff would install our gates.

If there are situations that are not covered by this Guide or questions of any sort that come up during the course of an installation do not hesitate to call, email, or write for clarification.

Watch Technologies is committed to assisting installation in every way possible so that our customers get the best use out of our gates.

Properly installing a gate is critical to immediate and long-‐ term performance.

The Gate

Regardless of size or style, all Watch Technologies gates share some features in common although every gate will not have every feature.

For example, some gates will have multiple threaded stems instead of a single stem, pedestals rather than frame mounted actuators, handwheels or electronic actuators, differently placed seals, and so forth.

All gates, however, mount to or in some kind of structure, have a frame, blade, blade guides, stem(s) or pneumatic ram, and actuation of some type.

If, after removing a gate from the pallet it was shipped on, there are questions regarding the gate or components associated with the gate please contact Watch Technologies before attempting an installation.

Watch Technologies assumes our customers have some familiarity with the purpose and setting for each gate.

This is important for proper installation planning.

Please contact Watch Technologies prior to planning an installation if there are any questions regarding these matters or the materials required to properly install a gate.

Most gates are not installed in convenient locations so advance planning is important to assure an efficient process.

Typical Gate

Figure below and right is a typical flush mounted Handwheel actuated gate.

It is meant to be installed on a concrete or similarly hard flat surface covering an opening through which water will flow and be controlled manually using the

Handwheel.

A Bill of Materials, also called a Cut List, located top right in the drawing details the components and measurements of this gate.

Watch

Technologies will use a drawing like this one to manufacture a gate.

Note the holes marked on the lower right portion of the frame and the measurements indicating their spacing;

these are the holes used for mounting this gate to a surface.

Unless otherwise noted, these holes are always 5/8” and sized to allow for1/2” threaded rod or Wedge-‐ Anchors typically recommended for mounting.

Installing a Gate

1.

Position the Gate

The first step in installing a gate is to pre-‐position the gate where it will be mounted to mark two (2) holes for anchors.

If pre-‐positioning the gate is not possible, carefully measure and mark the mounting surface for two holes, one on each side of the gate frame that will match two holes in the frame so the gate can be temporarily mounted to mark and drill the remaining mounting holes.

Pre-‐Position Gate holes are sized to allow Wedge Anchors to pass through the frame to the mounting surface.

Drill all holes 4”-‐6” into mounting surface.

2.

Place Anchors

If threaded rod is to be used for anchors, remove gate to allow placement of anchors and install

½” Stainless Steel threaded rods cut to appropriate length in each hole using a two-‐part epoxy glue to secure the rods in the concrete.

Allow hours to set.

Anchors of any type must be sufficiently long to account for a grout seal, see #5 below.

Fill all mounting holes with anchors.

If Wedge anchors are used the gate should not be removed from positing anchors.

Place all anchors into holes through the gate frame tapping them into place taking care not to damage

Figure 3.

Anchors anchor threads.

Install and tighten a Jam nuts on each Wedge anchor to tighten and lock Wedge Anchor into place.

Remove Jamb nut and gate after all Wedge anchors are secure.

3.

Jam Nuts

With the gate removed install

Thrust nuts on every anchor.

Thrust nuts are meant to provide an adjustable surface against which the gate will rest once it is plumb.

Adjust the nuts at each corner of the gate so the gate is plumb leaving a minimum ½ inch space between mounting surface

Figure 3.

Jam Nuts and gate and then bring the remaining nuts up snug to the back of the gate.

Re-‐ check for plumb.

4.

Secure the Gate

Place Jam nuts on each anchor and hand tighten to secure the gate.

Re-‐check plumb then firmly tighten Jam nuts to permanently secure the gate.

5.

Install Grout

Mix a non-‐shrinking grout and fill the space between the mounting surface and back of the gate and all gate surfaces that make a seal, for example

Figure 4.

Secure Gate an upper wiper seal across the top of the opening as shown in Figure 5.

It may be necessary to place a removable form around the grout locations to hold the grout in place until dry.

Make sure there are no voids in the grout.
