2.2 Detergent and rinse aid
NOTE
Only pre drilled hole and connections must be used for sensor, detergent
and rinse aid.
The dosing equipment is only to be connected in the detergent connection
box.
All dosing equipment must be fitted with a main switch.
Do not use detergent containing chlor.
To obtain the best performance of this GRANULDISK pot washer we strongly recommend
installing sensor controlled detergent dosing equipment and appropriate rinse aid equipment.
Figure 3: Detergent and rinse aid junction box
The 230 V AC and the 24 V AC supply as well as the control signals for the detergent and
rinse aid equipment are located in the junction box behind the front cover plate. There are
terminal blocks as listed below in the junction box (Picture:
Figure 4 Detergent and rinse aid
junction box ).
The dosing of rinse aid is normally done during filling of the rinse tank, depending on rinse
aid this could cause foaming in the rinse tank causing error 112. To avoid this the rinse aid
dosing equipment could use the detergent signal and the equipment set to dose on time, if
possible (fixed volume on positive flank). This means the dosing of rinse aid is done when the
rinse tank is full and the foam is avoided.
