Figure 18: Intermediate guide rail bracket installation illustration.

STEPS FOR FIGURE 181. With the guide rail pipe provided, measure out the sections. Guide rails are provided in

20’ sticks, and quantity depends on the total depth. The guide rails may need to be field cut due to exact well depth.

a) For example: If the well is 15’ deep, place the intermediate bracket no more than 10’ from the floor. This allows for two ~10’ sections and two ~5’ sections for each pump.

2. Loosely attach the U‐bolt to the bracket and slide the bracket down the discharge pipe to where the first section of guide rail pipe ends. If flanges do not allow sliding the bracket down the discharge line, remove the U‐bolt and reconnect it where the first section of the guide rail pipe ends.

3. Connect the next section of guide rail pipe directly on top of the intermediate bracket and tighten the U‐bolt nuts.

*Note: Not all stations require intermediate brackets. The following instructions are specifically for stations that are provided with this hardware.


STEPS FOR FIGURE 20

1. Loosely install the U‐bolts on the discharge pipes and extend the bracket tubing on each side to reach the inner walls of the well.

2. Drill hole for wedge anchors with Roto‐Hammer.

a) WARNING: Take care to not drill all the way through the wall.

3. Install wedge anchors.

4. Place bracket angles on each side.

5. Tighten wedge anchor hex heads, tighten U‐bolt hex heads.

Figure 19: Typical pipe bracket by Placer Waterworks Inc.

Figure 20: Shown above is an example of the pipe bracket installation, with a close up of the wedge anchor placement.

*Note: Not all stations require pipe bracing. The following instructions are specifically for stations that are provided with this hardware.


STEPS FOR FIGURE 211. Lower pumps down guide rails onto

base elbows.a) Lifting chain with shackles are

supplied with the pump station materials.

2. The weight of the pumps creates a water tight seal to the base elbow.a) There is a gasket between the

guide claw and base elbow.3. THERE IS NO BOLTING REQUIRED to

connect pumps to the base elbows.

Note: The hoist shown on this page is not always included. Use the proper lifting equipment to lower the pumps into the well and to raise the pumps out of the well.

Figure 21: Pump is lowered onto base elbow via guide rails.

*Double doorhatch orientation– see page 3*


Figure 23: The above illustration is an example of electrical cable management.

ELECTRICAL CABLE MANAGEMENT NOTES

• It is essential to utilize proper cord separation techniques when hanging electrical cables.

• The electrical contractor is responsible for conduit installation. Jensen Pump Stations recommends 2” minimum conduit for both high and low voltage.

• Pumps typically have two cables exiting the casing. Refer to the installation instructions provided by the pump manufacturer to identify the low voltage and high voltage cables (typically, the high voltage cables have a larger diameter).

• All low voltage and high voltage cords MUST be ran in separate conduits to the control panel.

• If low voltage and high voltage cables are placed in the same conduit, a current can be induced in the low voltage cables and create false seal fail alarms.

See the following page for continued information.


CONTROL PANEL INSTALLATION NOTES

• The location and installation of the control panel is the responsibility of the installing contractor or electrical contractor.

• Jensen Pump Stations recommends that the panel is mounted as close to the wet well as possible to avoid voltage loss and make start up and continued maintenance more convenient.

• The panel enclosure may be mounted on a nearby wall or within a nearby structure.

• Please pull all cables to the control panel. If the control panel is too far to use factory connections, contact JPS (775‐440‐2025) for longer cables. If a junction box is ABSOLUTELY necessary, take note of Pressure Transducer Handling instructions on page 4. It is crucial that the junction box is completely watertight.

• See Appendix A for junction box installation recommendations.

• Leave all excess cable coiled within the control panel. A JPS pump technician will make the electrical connections at time of start‐up/commissioning.
