AquaBlock 2 - Installation

2. Feed the 3/8-inch or 8mm OD paint line going to

the spray applicator(s) through the slotted opening

in the bottom of the cabinet. The tubing should be

shielded tubing, such as Ransburg part number

74178-01, or if other tubing is used it should be

covered with 1-inch (or equivalent) Polyurethane

tubing from the connection inside of the AquaBlock

2 cabinet to the applicator(s). Connect the tubing

to the fitting on the bottom of the 4-way shuttle

assembly and the other end to the applicator(s).

Figures 4 and 5 illustrate basic examples of typical

installations for the AquaBlock 2 system. Figure

4 shows a typical system with an isolated gear

pump flow control system, and Figure 5 shows a

typical system with an isolated flowmeter and fluid

regulator flow control system.

The paint line exiting the AquaBlock 2

cabinet should not be broken, or contain addi-

tional connections, from the connection at the

4-way shuttle assembly to the applicator(s).

If additional connections are required, for the

addition of flow control system components,

etc., special care must be taken to ensure

that the connections do not pass close to

ground sources that could cause current

leakage or electrical arcing. Additionally

the use of conductive com-ponents, such

as metal flowmeters or regulators, should

be limited as much as possible to decrease

system capacitance as much as possible.

The last 18-24-inches of the paint

supply hose connected to the fluid inlet of

the enclosure must be made of a non-con-

ductive material. This isolated fluid hose is

required to ensure proper operation of the

current meter.

C A U T I O N

Systems utilizing positive displacement

pumps for the regulation of the fluid flow to

the applicator(s) must be located after the

AquaBlock 2 in the charged fluid stream. This

is to avoid over-pressurization of the Aqua-

Block 2 system, or the paint tubing feeding

the system, during the switching operation.

This location requires that the pump and

any other conductive objects attached to the

pump be isolated from ground.
