2 Safety notes
– The additional devices may be connected to the electrical mains supply only by a specialist company registered within the elec-
trical trade and approved by the energy supplier.
– Work on the electrical system, installation and maintenance work as well as repairs may be carried out only by qualified specialists.
– When working on the electrical system, doing installation and maintenance work as well as repairs, observe the electrical engineer-
ing safety rules to avoid electrical accidents:
– Disconnect all power supply points.
– Secure the machine against being switched on again.
– Check that there is no voltage present.
– Earth and short circuit.
– Cover or cordon off neighbouring parts that are live.

NOTE
Danger of rusting and clogged jets caused by drilling swarf!
Rusting drilling swarf can also cause “stainless steel” to begin to rust.
ØRemove drilling swarf from the interior of the warewasher.
Note:Do not use a conductivity-controlled dosing device on warewashers with a built-in water softener. Regeneration salt that
enters into the tank can falsify measured values.

9 Connection examples for different dosing device types
9.1 Connect and adjust detergent dosing device
Dosing device with fixed output and time relay
For dosing devices with fixed output and a time relay, only post-dosing can be controlled. The pre-dosing can also be controlled with
two time relays.
With one time relay:
ØConnect to WASH terminal (}4).
ØSet time relay on the dosing device.
ðWhen the wash pump is running, detergent is dosed during the set time.
With two time relays:
ØConnect a time relay to the DETERGENT terminal (}4).
ØSet detergent dosing device to “While machine fills” (}5).
ØSet the time relay on the dosing device for dosing during the initial filling of the warewasher.
ðWhen the warewasher is filled for the first time, detergent is dosed during the set time.
ØConnect a time relay to the WASH terminal.
ØSet time relay on the dosing device.
ðWhen the wash pump is running, detergent is dosed during the set time.
Dosing device with adjustable output
For dosing devices with an adjustable output, detergent can be dosed in parallel with the opening time of the solenoid valve. Detergent
is then dosed during the initial filling of the tank and with each rinse. The output must be adjusted to the flow rate of the solenoid valve.
Calculating the output:
– Flow rate solenoid valve [l/min] x desired concentration [ml/l] = output [ml/min]
– Example: 4 l/min x 3.0 ml/l = 12.0 ml/min
ØConnect to DETERGENT terminal (}4).
ØSet output on the dosing device.
ØSet detergent dosing device to “Parallel to solenoid valve” (}5).
ðDuring the initial filling and when the rinse pump is running, detergent is dosed at the set output.
9.2 Connect and adjust the rinse aid dosing device
Dosing device with fixed output and time relay
ØConnect to RINSE terminal.
ØSet time relay on the dosing device.
ØSet the rinse aid dosing device to “Parallel to rinse pump” (}5).
ðWhen the rinse pump is running, rinse aid is dosed during the set time.
Dosing device with adjustable output
Calculating the output:
– Flow rate solenoid valve [l/min] x desired concentration [ml/l] = output [ml/min]
– Example: 4 l/min x 0.3 ml/l = 1.2 ml/min
ØConnect to RINSE terminal (}4).
ØSet output on the dosing device.
ØSet the rinse aid dosing device to “Parallel to rinse pump” (}5).
ðWhen the rinse pump is running, rinse aid is dosed with the set output.
