
All electrical connections to the TWINDOSE 20
should first be verified with a meter.
Application of incorrect voltage will permanently damage the unit an
d is not covered
under warranty. Avoid wiring to any power source that has large fluctuations in voltage
and/or is prone to surges. Refer to the wiring diagram in this manual for all power and
signal connections.

Check the voltage of the main power sou
rce and make sure that it matches one of
the three available input voltages (24
-
115
-
230 Vac) of the transformer inside the
TWINDOSE 20.

INSTALLATION
Mount the unit on a nearby wall (using suitable hardware) of the warewasher. Try to keep the unit
within three feet from the final rinse line to avoid long tubing runs.
Check all applicable plumbing and electrical codes
before proceeding with the installation. This
will help to ensure that the system is installed in safe and suitable manner. A wiring schematic of
the warewasher should be used as reference for making electrical connections, this is typically
provided by th
e warewasher manufacturer if one cannot be located on the machine itself.

CAUTION: Do not mount the unit in the direct path of steam. This can short circuit and
permanently damage the unit. Mounting the unit on the side, on the back or on the vents
of th
e warewasher may cause thermal overload and damage or hinder the performance of
the unit.
2.1
MOUNTING THE SYS
TEM
Apply the panel unit system with the brackets and screws supplied:


Determine a suitable location for the system;


Using the bracket as a temp
late, mark and drill holes for bolting the system to the wall;


Insert the anchors in the holes;


Bolt the bracket in place (flat side against the wall with holes on bottom) with the hardware
provided;


Open the Cabinet Front, unscrewing of ¼ of a turn the u
