dispenseIT Manual – Installation

Table of Contents

Place equipment in the equipment room where the installation will commence
- If possible, have the unit away from areas where the pump could take a direct spray from liquids.
Floor Mount dispenseIT: Turn the swivel casters so the wheels point forward and lock in place to ensure maximum stability (fig. 1.1-1.2)
- Safety chain is not required
Wall Mount dispenseIT: Place the pump on the floor to the right of the unit.
- Be sure to install a stainless steel guard around the pump’s base to avoid damage by barrels, barrel carts, etc.
- Recommended height is at least 4’, measured from the bottom of the frame to the floor

Pay attention to the direction of the vent hole during liquid filling and venting. Make sure that the escaping liquid does not cause damage to the motor or other components.
If the pump runs dry, the pump bearings and the shaft seal may be damaged.
For additional information, refer to the information in the Grundfos instruction manual.
To begin priming, close the outlet isolation valve on the discharge side of the pump and remove the priming plug (fig.3)

Open the vent valve
Open water supply to the inlet of the pump
- Once water starts coming out of the vent valve, start the pump
- Keep the isolation valve on the discharge side of the pump closed
Let the pump run for 2 minutes, spraying water out of the vent valve
- Have a bucket ready to collect the sprayed water
After 2 minutes of running, shut off the vent valve. Then turn the pump off.
- Do not over tighten the vent valve
Slowly open the isolation valve on the discharge side of the pump
Pump is now primed

The above steps should be repeated any time the pump may have been drained or lost its water supply

Install main airline feed to inlet side of air regulator (fig. 5). Refer to page 5 for specifications

Be sure the pump voltage matches the voltage that is being supplied to the pump. Check pump sticker (fig. 6)

Use the bottom hole of the pump’s electrical box for the 3 phase incoming power (fig. 7)

Use the bottom hole of the pump’s electrical box for the 3 phase incoming power
Use remaining holes for wire connections
Connect the grounding conductor to the ground lug (fig. 8). Connect the 3ph power to the pump’s terminal strip (terminal wiring plug can pull out for wiring ease. Inspect to ensure the terminal plug is fully seated.

On the wall-mounted dispenseIT connect the “run signal” wires from the control box to the pump
- Control box terminal strip #PTS1 and PTS2 (fig. 9)

Control wiring connections for your tunnel controller: Please consult the provider of your tunnel controller for installation instructions for the terminations
Control wiring connections on the dispenseIT system
- Connect (1) “hot” conductor from the tunnel controller to each function in the control box on the terminal strip
  - Working from left to right
    - TS 1-15 for ports 1-15 on 15 function (fig. 11.1)
    - TS 1-20 for ports 1-20 on 20 function (fig. 11.2)
    - TS #’S are the “hot” signal wire from the tunnel controller
- Connect (1) neutral/ common conductor for the system in the “NEUT” terminal strip
  - NTS #’s are the “neutral/ common” wire from the tunnel controller (fig. 11.3)
- Connect (1) ground conductor to the green grounding terminal strip
- There is one spare hole in each function’s terminal strip for the control wire from your tunnel controller
  - It will be the second hole down from the top on the terminal strip

Connect ½” liquid lines to the appropriate injector port as specified in your customer configuration form

Connector 3/8” poly tube airlines to the appropriate port on top of the system as specified on the customer configuration form
Functions are identified 1-15 or 1-20 from left to right
