Safety
General
Carefully read this manual before installing, starting up and servicing the DICETM dosing
module.
Warning notes must be strictly followed in order to
avoid injuries and damages.
The module is internally pressurized and can
cause injuries if not handled correctly.
The fluids* used in the dosing module or in the
cleaning process may be hazardous.
The following minimum personal protective
equipment should be used near the dosing module:
protective gloves, glasses and clothing.
Always refer to the MSDS for all safety
instructions related to the fluids* used.
Turn off electrical power, depressurize system,
release both regulating valves (back pressure valve and
pressure relief valve), and vent fluids* to a safe area
before servicing the DICETM dosing module.
Always flush all fluids* prior to module
maintenance.
Refer to technical specifications for the maximum
operating flow, pressure and operating temperature.
Modifying the DICETM module, installing non-factory parts or not following the
maintenance procedure listed in the present manual may cause injuries, affect product
performance, be hazardous and void existing limited warranties.
*Note: Fluids include: chemicals, polymer solutions, cleaning solutions, water, etc.

Unpacking and Storage
Unpacking
When unpacking the product, ensure that it is defect-free and according to the purchase
order. Please notify Meunier Technologies Inc. or your supplier if there are any
irregularities.
Avoid any changes to the back pressure valve and pressure relief valve as they may be
factory set. Factory set valves are labelled with the desired pressure at each valve.
The box should contain one (1) DICETM dosing module, one (1) IOM (Installation,
Operation and Maintenance) manual and the purchased spare parts.
Storage and Handling
The DICETM dosing module ball valves should be stored in a fully closed
position. Storing the DICETM dosing module with partially open ball valves
could cause permanent damage to the ball valve seats, which could lead to ball
valve leakage.
The DICETM dosing module must be stored indoors, inside its cardboard box, at a
temperature of between 5 °C to 40 °C and with a relative humidity level under
80%.
The DICETM dosing module must be stored without any pre-set pressure on the
back pressure valve and pressure relief valve.
Excessive stacking of packages may cause damage to the product. Never stack
more than five (5) DICETM dosing modules.

© Meunier Technologies Inc. 2021 - All rights reserved 6
Do not store the DICETM dosing module in a corrosive environment or directly
exposed to sunlight.
Handle the DICETM dosing module with care. Never throw the dosing module,
even when it is in its cardboard box. The product is not designed to sustain
impact.
When transporting the DICETM dosing module, do not carry it by the ball valve
handle or the connectors.

Installation
Warning! Always use the proper tool for each step of the installation.
Mounting
The DICETM dosing module is designed to be mounted on a planar surface using the
three (3) mounting holes. The DICETM should always be mounted so that the injection
port is facing upwards as shown in the following figure. To avoid accumulation and
trapped air, the DICETM should always be levelled.

© Meunier Technologies Inc. 2021 - All rights reserved 15
To avoid mechanical stress on the DICETM body, put the three (3) washers (31) provided
between each of the mounting holes (rear face) and the mounting surface. It is
important to make sure that no corner is touching the mounting surface. Only the
washers should touch the mounting surface. See the following figure for this type of
mounting. Mounting holes can accommodate both M6 and ¼ size socket head screws.
Each screw should be torqued to 35 in-lb.
When installing the DICETM dosing module, remember to factor in sufficient space for
module maintenance.

Connections
In order to suit all application needs, a variety of connections are
available. All connections (NPT, Socket, Hose, etc.) are assembled on
the block using the mushroom nut (25). This type of assembly allows
for simple disassembly of connections, thereby avoiding the need to
cut any pipe when doing maintenance.
In order to assemble the pipe with the chosen connection type, slide the mushroom nut
(25) onto the connector (26/27/28). Insert the pipe or flexible hose into the connector
according to state-of-the-art rules so that the two parts are securely fastened to each
other.
The pipes and tubing should be perfectly aligned with the dosing module connections to
prevent mechanical stress. Excessive stress can cause part failure.
Once the assembly is completed, fasten it to the desired port on the block. When
tightening the mushroom nut (25), verify that the o-ring (30) is well positioned in the
connector groove (26/27/28). The mushroom nut (25) should be hand tightened only;
no tools should be used for this. Ensure that the o-ring is properly squeezed.
Connectors: Socket (26), NPT (27), Hose (28), Cap (29)
If an accessory is connected to the accessory port (ex: pulsation damper), it must be
equipped with its own support. The dosing module is not designed to support the
accessory weight.
Note: 25, 26 and 27 are exemplary connectors. All the connector configurations can be
found in the Model Number nomenclature of the IOM (Installation, Operation and
Maintenance Manual).

Typical Installation
The following figures can be used as a typical installation of the DICETM dosing module in
a dosing system.
Note: Never use a pipe wrench for dosing module installation.

Operation
Start-up
Prior to system start-up, the responsible individuals should be informed of the safety
instructions to be followed. This manual should be available at all times.
Setup and adjustment
The pressure relief and back pressure valve needs to be adjusted prior to system
operation.
Note: If requested upon purchase, the back pressure and pressure relief valve can be
factory preset. If so, no adjustment is required prior to system operation.

© Meunier Technologies Inc. 2021 - All rights reserved 19
Pump priming assistance
In order to assist and optimise initial pump
priming, a bleed valve (32) has been integrated
on the left side of the DICE Module. The valve
allows evacuating potential trapped gas between
the pump outlet and the back pressure valve that
could be preventing the pump from priming.
In order to assist pump priming, slightly open the
bleed valve (32) by unscrewing it while the pump
is cycling until fluid starts passing through. Only
partial unscrewing is required. The Bleed valve
does not need to be (and should not be) fully
unscrewed to assist pump priming.
Then simply close the bleed valve and carry on with either the DICETM set-up and
adjustment or the system normal operation.
Note: The bleed valve can also assist with pump priming if the pump loses prime during
normal operation.

© Meunier Technologies Inc. 2021 - All rights reserved 20
Pressure relief valve adjustment
In order to adjust the set point of the Pressure Relief valve, the module’s three ball
valves must be in the closed position.
Start by screwing completely the back pressure adjustment screw (19').
Start the pump and wait until fluid passes through the pressure relief valve into the
evacuation port. Use the adjustment screw (19) to obtain the desired pressure set point.
Once the desired set-pressure is obtained, tighten the counter nut (20), stop the pump
and slowly open the evacuation valve to release the system pressure.
Proceed with the back pressure valve adjustment.
Notes:
The maximum torque to be applied on the adjustment screw (19 & 19') and
counter nut (20 & 20') is 35 in-lb.
Turning the screw clockwise increases the set pressure.
