3.6 Dispensing system overview

The DV 270.2 is designed for use

with a liquid rinse aid, and either

solid or liquid detergents.

Units equipped with optional liquid

internal detergent and rinse aid

pumps have two tubes exiting the

machine at the lower rear. These

tubes can simply be attached to

detergent and rinse aid containers.

See Figure 3-6.

Units that are NOT equipped with

the internal pumps have:

• A blue rinse aid line exiting the

machine at the lower rear.

• Two dummy plugs covering

holes in the back of the wash

tank that can be used for de-

tergent injection. The plugs are

accessed by removable panels

on the sides of the machine.

Either plug can be used.

• A hole in the bottom of the wash

tank for the installation of a de-

tergent concentration probe.

A dispensing system terminal block

(shown in Figure 3-6) provides

contacts for two line voltage

relays. These relays, when closed,

provide a “window” for external

pump systems to activate.

• The rinse aid pump relay closes

for approximately 16.5 seconds

whenever the booster tank

refills (once per cycle).

• The detergent pump relay

closes whenever the wash

pump is in operation.

Activation of the pumps can be

controlled as follows:

• Solid detergent systems should

use a detergent concentration

probe installed in the wash tank

to activate the external pump.

A dummy plug at the bottom of

the wash tank provides an

installation location for the probe.
