Hot Water Operation (Optional, Only With Upstream Mixer Tap) - Ecolab DG1-III-DLA-PCB Operating Instructions Manual

Sequence steps for removal of ready-to-use disinfectant solution:
1.
Place a vessel / bucket below the swivel spout.
2.
Starting the dosing process by pressing the start button
3.

ð Risk of slipping due to product on the floor.
Pressing the start button
time, the dosing pump is activated, which sucks in disinfectant from the product reservoir
according to the set concentration.
Disinfectant is added in proportion to quantity and mixed with the water in the swivel outlet
to form a ready-to-use solution.
The withdrawal continues until the stop (pause) button
The entire process is regulated by the integrated microprocessor control.
The impulse water meter records the amount of water supplied.
The control electronics activate the digital linear drive (DLA), which drives the double-
acting piston metering pump. This ensures that the disinfectant is added in proportion to
the quantity.
The disinfectant flow is constantly monitored by means of a flow monitor located upstream
of the dosing point.
The water flow is controlled by means of a pulse water meter. In case of product shortage,
water shortage or a malfunction, the appliance switches off immediately.
The red LED signals the error with different flashing intervals.

Hot water operation (optional, only with upstream mixer tap)

If necessary, DG1-III can also be operated with hot water.
A mixer tap must be connected upstream for this purpose.
CAUTION!
The max. permissible input temperature must not be exceeded under any
circumstances, see also
Furthermore, the instructions which are supplied with the relevant chemical
product must be followed.
Conversion to hot water operation
The device can be retrofitted for hot water operation (max. 30 °C).
The precondition for this is the installation of an external thermostatic mixer tap.
For this retrofit, a separate cold and hot water connection must be available
at the installation site.
A matching thermostatic mixer tap can be ordered separately from Ecolab or obtained
from sanitary retailers.
