Bleeding Product Dosing Pumps (Iwaki - EB Series Pumps)
The need to bleed product dosing pump will arise when products have run out or in some
case when products have been replaced and air has become trapped in the tube.
Bleeding procedure:
1. Select the product you wish to bleed by turning the rotary switch e.g.: shampoo
2. Adjust stroke rate to 90%;
3. Release bleeder valve (item A below) by turning anti-clockwise as shown below; 3
turns only.
4. Once product reaches the clear waste tube (item B below) re-tighten the bleeder
valve by turning clock-wise;
5. Reset stroke rate to the previous/recommended setting;
6. After process is complete visually inspect the suction line for air pockets-if air pockets
are present repeat process.
NOTE: After pump has been bled, there will be a distinctive change in the sound of the pump
(pump will sound quieter).
If there are problems bleeding heavier concentrates rattle the suction line (item C
below), and/or squeeze it to assist with shifting the product up into the pump head.
