Installation Procedure

Pump Box

For non-flushed systems, install pump box 5 meters (15 feet) or less from the washer, with a maximum vertical rise of 3 meters (10 feet).

For flushed systems, install the pump box within 17 meters (50 feet) of the washer and with a maximum vertical rise of 3 meters (10 feet).

Mounting the L5000Plus too high may result in compromised flow rates and excessive tube wear.

Wall Mounting

1. Select a place on the wall where the pump box will be at eye level. Be sure to allow enough space above the pump box so that you can easily open the top.
2. Open the front door to the pump box and hold it up on the wall. Use a level if necessary.
3. Mark the keyhole slots with a pen or pencil. You may also mark the lower round hole if you want to place and additional screw in for stability.

Figure 1a. Mounting L5000Plus to wall

Auxiliary Pump Boxes

Wall Mounting

L5000Plus auxiliary ("aux") boxes come with holes on the right and left sides for threading the pump wires to the pump box main PCB. The left side has an "open" terminal plug and the right side has a "closed" (solid) terminal plug. As you add additional aux boxes to your system, you can swap the "closed" terminal plugs for "open" terminal plugs.

You can simply hang your aux boxes on the wall, securing them with screws in the keyhole slots. But for added stability, you can bolt the aux box to the main pump box (or aux boxes to each other) using the small holes in the upper right and left sides of the aux box. See Figure 2.

Auxiliary Pump Box Mounting Instructions

1. Position aux box on the wall flush with the right side of the L5000Plus pump box.
2. With the aux box open, locate the keyhole slot at the back of the box and mark the top of the keyhole slot with a pen or pencil.
3. Drill a hole where you marked the keyhole slot.
4. Screw the pump box to the wall using the screws provided.
5. If desired, bolt the aux box to the L5000Plus pump box (or other aux boxes) through the holes in the top right/left sides of the aux box using screws, nuts and threaded spacers provided.

Figure 2. Bolting auxiliary pump box to main pump box

Connecting Tubing

To protect against pressurized chemical spray, wrap a rag around tube connections when replacing tubes and always wear gloves and safety glasses.

Do not run tube above electrical connections and boxes. Provide adequate clearances near steam pipes and other hot surfaces.

The viscosity of the chemicals you pump will impact the flow rate and the maximum distances chemical can be transported without flush.

Suction Tubing

Standard suction tubing is 3/8" or 10 mm ID. For viscous products, use 1/2" or 12 mm ID tubing.

1. Position chemical drums as close to the L5000Plus as possible to minimize the suction tube run length.
2. Connect suction tubing to the left pump barbs and secure with metal hose clamps.
3. For optimal performance, we suggest using a tube stiffener (standpipe) for each chemical.

Figure 3. Connecting suction tubing

Transport Tubing

For 600 Series pumps we recommend using 10 mm or 3/8" ID tubing.

Regardless of the pump size, we recommend using stiff tubing such as Nylobraid when pumping viscous chemicals.

1. Connect the transport tube to the right-side pump barbs and secure with metal hose clamps.
2. Run the tube to the washer or flush manifold.

Electrical Installation

We recommend that you attach the main system ground to the bottom ring terminal to provide a more secure ground connection.

Only use trigger and main power wiring hole connections which provide strain relief, such as cable glands, strain reliefs or conduit connections. Conduit is recommended.

Use only double-insulated (0.8 mm) reinforced wire for main power and trigger connections, subject to local electrical code requirements.

When installing power wiring through a conduit fitting, electrical insulation must be provided to prevent the wires from wearing against possible sharp edges of the fitting.

Use 15 Amp branch circuit protection.

A circuit breaker must be included in the installation's building. It must be installed in close proximity to the equipment and within easy reach of the operator and it must be marked as the disconnecting device for the equipment.

Hole plugs must be used on holes through which you have not routed wires.

5. Connect the mains voltage power to the terminal strip according to label designations, "L" (hot), "N" (neutral).
6. Disconnect the yellow, insulated terminal clip, crimp main ground wires to it and then reconnect.

Trigger Signal Connections (TR8000 L) (Refer to Figure 7)

Ensure that the trigger wire voltage and temperature rating are suitable for the application. The current required for the triggers is only 5mA. Wires must be 24-14 AWG.

The TR8000 L is pre-installed inside the pump box, but can be removed for installation within the washer control box or mounted elsewhere inside an approved enclosure.

The TR8000 L serves as the high-voltage interface between the L5000Plus and the washer trigger signals. It also serves as the wiring connection between the programmer and the L5000Plus pump box.

The TR8000 L is prewired with its supply commons (-) looped, or jumpered. If the washer supply common comes from a single circuit, then the common can be connected to any of these. Simply disconnect any one of them and connect the washer supply common.

If your washer supply's commons come from more than one circuit, then you will need to disconnect and reconnect as many as you need.

If the TR8000 L will be removed from pump box and placed on/in washer:

If TR8000 L will be removed from pump box and installed on/in the washer, it must be installed within a regulatory-compliant, electrical-rated enclosure.

1. Remove TR8000 L from pump box as shown in Figure 8.

Figure 8. Removing TR8000 L from pump box

1. Mount TR8000 L inside of washer, or on its outside using the Velcro strips provided.
2. Connect washer power supply trigger wires to TR8000L terminals, using the Figure 10 table as a guide. To open each terminal, press it downward using a screwdriver (see Figure 9). Insert washer power supply wires into terminals.

Figure 9. Using screwdriver to open wire clamp

T8 is not available for triggering pump actions in Formula or Latched Modes. In these modes, T8 is only used for signal monitoring and formula selection.

If TR8000 L will remain in the pump box:

1. Thread conduit from washer power source through one of the holes in the bottom of the pump box.
2. Connect washer power supply trigger wires to TR8000L terminals, using the Figure table as a guide. To open each terminal, press it downward using a screwdriver (see Figure 9). Insert washer power supply wires into terminals.
