Setup

Location

• The system should always be used on a level

surface.

• Do not expose the system to rain.

Electrical Requirements

• Required power source: single dedicated circuit that

is rated at a minimum of 15A.

NOTE: Cords must be 3-conductor grounded, rated for

your environment.

• Power cord connector (120V):

One NEMA 5-15T

• Extension cord requirements:

Grounding

System: grounded through power cord.

Generator (if used): follow your local code and

manufacturer’s recommendations. Start and stop the

generator with power cord(s) disconnected.

Spray gun:ground through connection to a properly

grounded fluid hose and system.

Fluid supply container: follow local code.

Object being sprayed: follow local code.

Solvent pails used when flushing: follow local code.

Use only conductive metal pails, placed on a grounded

surface. Do not place the pail on a nonconductive

surface, such as paper or cardboard, which interrupts

grounding continuity.

To maintain grounding continuity when flushing or

relieving pressure: hold metal part of the spray gun

firmly to the side of a grounded metal pail, then trigger

the gun.

Required Wire Size

Up to 50 ft (15 m) Up to 100 ft (30 m)

AWG 14 AWG 12

The equipment must be grounded to reduce the risk

of static sparking and electric shock. Electric or static

sparking can cause fumes to ignite or explode.

Improper grounding can cause electric shock.

Grounding provides an escape wire for the electric

current.

Setup

FIG

3A5743C

Connect Fluid Hoses

Connect the fluid supply hoses to outlet hose

connections (FIG. 3). Red hoses for component A (ISO),

blue for component B (RES). Fittings are sized to

prevent connection errors. Connect the other end of

hoses to A and B inputs of the gun.

Connect Gun to Air Hose

(Air-Operated Guns Only)

Connect the gun air hose to the gun air input and to the

air filter outlet. If you are using more than one hose

bundle, join the air hoses with the nipple provided with

the hose bundle.

Connect Main Air Supply

The system requires 4 scfm (0.112 m3/min) compressed

airfor the air operated spray guns to work correctly.

Connect the main air supply to the quick disconnect

fitting on the unit. The air supply hose must be at least

5/16 in. (8 mm) ID up to 50 ft (15 m) or 3/8 in. (10 mm)

ID up to 100 ft (30 m).

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is

left in the fluid passages to protect parts. To avoid

contaminating your fluid with oil, flush the equipment

with a compatible solvent before using the equipment.

See Flushing, page 19.

NOTICE

To prevent pressure fluctuations and equipment

damage, only operate equipment with fluid supply

hoses longer than 25 ft.

Setup

Fill Wet-cups

Keep the felt washers in the pump wet-cups saturated

with ISO pump oil. The lubricant creates a barrier

between the ISO and the atmosphere.

Fill wet-cups through the slots in the plate, or remove a

screw and swing the plate to the side.

The pump rod and connecting rod move during

operation. Moving parts can cause serious injury such

as pinching or amputation. Keep hands and fingers

away from the wet-cup during operation. Shut off

power before filling the wet-cup.
