Always use the proper tool for each step. Never use a pipe wrench on the DICE module.

​
Mounting

Source: DICE IOM Manual V12E, Section: Mounting, Page: 14 The DICE module mounts to a planar surface using three mounting holes on the rear face.

​
Requirements

  • Mount with the injection port facing upward
  • Keep the module level to prevent trapped air
  • Allow sufficient clearance for maintenance access

​
Mounting Procedure

1

Position the washers

Place the three provided washers (part 31) between each mounting hole and the mounting surface. The washers isolate the module body from the mounting surface.
2

Verify clearance

Confirm no corner of the module touches the mounting surface. Only the washers should contact the surface.
3

Install mounting screws

Mounting holes accept M6 or 1/4” socket head screws. Torque: 35 in-lb.

Using the washers prevents mechanical stress on the DICE body. Stress from improper mounting can cause part failure.

​
Connections

Source: DICE IOM Manual V12E, Section: Connections, Page: 15 DICE uses a mushroom nut connection system that allows tool-free assembly and disassembly.

​
Connection Assembly

1

Prepare the connector

Slide the mushroom nut (25) onto the connector (26/27/28). Insert the pipe or tubing into the connector.
2

Align piping

Ensure pipes and tubing are perfectly aligned with the module port. Misalignment causes mechanical stress that can lead to failure.
3

Verify O-ring position

Confirm the O-ring (30) is properly seated in the connector groove.
4

Hand-tighten only

Thread the mushroom nut onto the port and tighten by hand only. Do not use tools.

If connecting accessories (pulsation dampener, flow monitor, etc.) to auxiliary ports, provide independent support for the accessory. The DICE module is not designed to support accessory weight.

Typical Installations

The DS configuration uses suction lift from a chemical tank located below the dosing system.

​
Installation Examples

Mount the DICE module vertically above the dosing pump. This configuration:
  • Minimizes piping runs
  • Facilitates gas evacuation
  • Provides clear access for operation
Connect two dosing pumps to auxiliary ports for redundancy. Each pump should include an integral check valve. The DICE module consolidates both pump outputs through a single back pressure and relief system.
Connect a pulsation dampener to an auxiliary port when using diaphragm pumps that create significant pulsation. Support the dampener independently.

DICE DS — Suction Lift

1/2” module for suction lift applications

DICE DM — Flooded Suction

1/2” and 1” modules for flooded suction
