Installation

Improper wiring may cause electric shock or other serious injury. All electrical wiring must be done by a qualified electrician and comply with all local codes and regulations.

Power Supply

See Table 1 for power supply requirements. The system requires a dedicated circuit protected with a circuit breaker.

Connect Power

1.

Cut power cord wires to the following lengths:

• Ground wire - 6.5 inches (16.5 cm)

• Power wires - 3.0 inches (7.6 cm)

• Add ferrules as necessary. See F IG . 2.

2.

Bring cord to unit and remove two screws to separate junction box cover (G) and power switch (E)

from remainder of sprayer. See F

NOTE: Two wires will be installed in both terminals.

See F IG . 4:

• For Series A and B: terminals 1L1 and 3L2

• For Series C: terminals 1L1 and 5L3

NOTE: Press gasket against back sealing face of junction box cover to ease installation of power cord.

5.

Attach ground wire to ground terminal inside junction box (S).

NOTE: The power cord attaches to a separate ground screw than the ground screw that is already attached.

Replace junction box screws and washers removed in step 2 and tighten cord grip to securely hold

power cord in junction box (S). See F

Place fan wires and other power wires into open area on either side of disconnect block (J) as space

permits. Reinstall junction box cover. See F IG . 5.

NOTICE

If wires get pinched when the screws are tightened, damage will occur. Make sure all wires are routed correctly before installation.

Installation

Grounding

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.

Sprayer: system is grounded through the power cord.

Fluid hoses: use only electrically conductive hoses with a maximum of 210 ft. (64 m) combined hose length to ensure grounding continuity. Check electrical resistance of hoses. If total resistance to ground exceeds 25 mega ohms, replace hose immediately.

Spray gun: ground through connection to a properly grounded fluid hose and pump.

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 non-conductive 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/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve.

Fill With Oil Before Using

Equipment

Before using the equipment, open fill cap (P) and add

Graco Part No. 16W645 ISO 220 silicone-free synthetic gear oil. Check the oil level in the sight glass (K).

See F

IG

. 7.

Fill until the oil level is near the halfway point of the sight glass. The oil capacity is approximately 1.0 - 1.2 quarts

(0.9 - 1.1 liters). Do not overfill.

NOTE: Two 1 quart (0.95 liters) bottles of oil are supplied with equipment.

NOTICE

Only use oil 16W645. Any other oil will reduce the life of the gears.

Flush Before Using Equipment

The pump fluid section 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 Prime/Flush procedure, page 11.
