* The controller (E) is designed for use in a non-hazardous location as defined in the National Electrical Code (USA). To install the Batch
Dispense equipment in a Class 1, Division 1, Group C and D environment, the X-purge option (F) must be properly installed. Follow the
instructions on pages 60–66.
Figure 2 – Typical Installation

Install the Fluid Supply

Connect the fluid and air supply lines as shown in the
system and controller drawings starting on page 54.
The installation and operation instructions in this manu-
al generally presume a standard system, using pres-
sure tanks (A) to supply the paint components and sol-
vent. The optional fluid supplies listed below are
possible variations and their effect on the instructions.
Optional Fluid Supplies
Instead of pressure tanks (A), the BDS can be supplied
by pail or drum pumps or central paint recirculating
lines if they are available. An air piloted, fluid pressure
regulator is required on each supply line at the input to
the BDS.

Other than references to the pressure tanks, operation
using other fluid supplies is the same as described in
this manual. For maintenance and safety, you must
install a fluid shutoff valve between each supply line
and the BDS.
The fluid supply must be free of pressure spikes, which
are commonly caused by a pump stroke changeover. If
necessary, install pressure regulators or a surge tank
on the fluid supply outlets. Note that this will also
reduce the fluid supply pressure.
