Diagram
Adjustment
Turning the adjusting screw clockwise increases the dosing time from 0 to 30 seconds.
The factory setting is 12 seconds, which equates to about 0.5 ml / litre on a glasswasher
using 2.6 litres per cycle.
The volume of rinse fluid required will depend on factors such as product type, water
hardness and whether glasses or dishes are being washed, but about 0.5 ml per litre of water
is typical. Excessive use can cause de-fizzing of carbonated drinks, streaky or greasy
washware and/or foaming of wash water. If in doubt - reduce injection quantities.
Troubleshooting
1. Check if the inlet hose is submerged in rinse fluid or that there is no blockage or
restriction in one of the hoses, the inlet or the connection tee. Some Rinse Fluids crystallise
or gel over time and can block the inlet.
2. Squeeze tube worn and requires replacement.
3. Non return valve (NRV) attached to tee is inoperative. The NRV should prevent fluid
flowing down the inlet tube at the end of the cycle. Replace if faulty.
