1INTRODUCTION
The Leader MIX CLASSE B/AR & CLASSE A 200-1000 l/min (50-275 gpm) is a variable flow dosing system which
can be used to inject foam concentrate into a pressurised water network.
There is a remote console for the Fixed model.
The Leader MIX CLASSE B/AR & CLASSE A 200-1000 l/min (50-275 gpm) automatically adapts to the network flow.
The Portable model is equipped with a pressure meter and a suction indicator.
The Fixed model is equipped with a remote console.
It works similarly to in-line venturi injectors, it replaces 3 traditional injectors: 200, 400 and 800 L/min (50, 100 and 200 gpm).
It does not require a power supply or specific maintenance (just rinse and purge the system after use).
There are 2 models: Portable or Fixed.

The Leader Mix CLASSE B/AR & CLASSE A 200-1000 l/min (50-275 gpm) is equipped with a suction indicator.
The Leader Mix CLASSE B/AR & CLASSE A 200-1000 l/min (50-275 gpm) usage flow range varies depending on the
supply pressure. The table below can be used to assess the flow range depending on available pressure.
6COMMISSIONING INSTRUCTIONS
On delivery, visually inspect Leader MIX and its accessories to ensure there was no damage during transport.
Do not try to use Leader MIX if you can see any damage, inform LEADER immediately.
Ensure that each person responsible for the device/using this device has read the user instructions and safety guidelines.

- valves will need to be installed for “Female 1/4ˮ G” connections intended for rinsing and purging water input and
output and foam concentrate rinsing, as well as for the “Male 1ˮ G” foam concentrate input.
- Remove the water input/output caps using a hex wrench/6 mm (0.02ft) and foam concentrate rinsing using a hex
wrench/5 mm (0.016ft) (fig 1), then mount the valves (fig 2) and ensure that they are sealed correctly.

7.2.2 Remote controle console
For the Fixed Model, all Leader MIX CLASSE B/AR & CLASSE A 200-1000 l/min (50-275 gpm) functionalities can
be made remote via a console, which is very easy to connect.
The console allows you to:
- Show the pressure at the entrance of the Leader MIX.
- Select Water or Foam positions.
- Rinse the system.
Fixing points :
M5 (0.016ft) screw (x4 not supplied).
Length to be determined by the installer.
Connection:
The length of hose will depend on the distance between Leader MIX CLASSE B/AR & CLASSE A 200-1000 l/min
(50-275 gpm) and control panel.
To connect control panel to Leader MIX CLASSE B/AR & CLASSE A 200-1000 l/min (50-275 gpm), 8mm (0.026ft)
24 bars (350psi) pneumatic hose is recommended. LEADER can supply (optional) this hose. Item number is 2009779 and
it is sold on real of 30m (9.85ft).
After each disconnecting of hose it is mandatory to cut the end of the hose before reconnecting it.

8.1 Portable Model
Always rinse and purge the device after use.
1) Remove the suction tube from the foam concentrate tank by holding the tube on the Leader MIX.
2) Position the injection selector to “FLUSH“ & “WATER“.
3) Leave the water network pressurised (6 bars (87psi) maximum) and turn the dosing selector dial round twice whilst
pressing and holding the purge button. Water will then be directed through the foam concentrate circuit to clean it, and
then discharged through the suction tube pipe.

Problem
What to do
Incorrect dosing or
no dosing
•Check that the injection selector is on “Foam”
•Check the foam concentrate input suction
•Check the position of the % dosing selector
•Check that there is foam concentrate left
•Check that the suction tube is not capped (Portable Model)
•Check the flow range and pressure
•Check that the suction tube has not been modified in length or diameter
•Check there are no impurities or debris (sand, stones...) at the injector input. If there are
impurities or debris (stones, sand...) inside the injector, turn to “Water” position: 5mm
debris can be removed
•Check the water pressure: it must be above 5 bars (72psi) (P8 usage range)
•Check the water flow: it must be above 200 l/min (50gpm) (P8 usage range)
•Check the foam concentrate status
•Check that the injector is not clogged due to insufficient rinsing
Incorrect rinsing or
no rinsing
•Check that the injection selector is on “Flush & Water”
•Turn the dosing selector round twice
•Keep the purge button held down when using (Portable Model)
•Check that the network is pressurised.
