• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

6 3A3948H

Installation

If using a flammable gas to drive the motor, to reduce the risk of fire or explosion, route the exhaust away

from all sources of ignition. See Route Exhaust to

Remote Location on page 9.

NOTE: 3.5% of the exhaust is not recoverable, and will vent to atmosphere at the pump.

To reduce the risk of injury from ejected ice, do not operate the motor without a plumbed exhaust line or muffler installed.

Installation must comply with all local codes and regulations.

Grounding

The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding provides an escape wire for the electric current.

Pump: ground through electrically conductive pneumatic and fluid lines.

Pneumatic and fluid lines: use only electrically conductive lines.

Air compressor: follow manufacturer’s recommendations.

Fluid supply container: follow local code.

Required Accessories

Install the following required accessories in the order

shown in F IG . 1, using adapters as necessary. See

Kits and Accessories

starting on page 40.

Pneumatic Line

• Bleed-type master pneumatic valve (D): required in your system to relieve air/gas trapped between it and the pneumatic motor when the valve is closed.

• Be sure the valve is easily accessible from the pump and located downstream from the pneumatic regulator.

• Pump pneumatic regulator (E): to control pump speed and outlet pressure. Locate it close to the pump.

• Pneumatic line filter (C): removes harmful dirt and moisture from compressed air/gas supply.

• Second bleed-type pneumatic valve (pneumatic shutoff valve) (B): isolates pneumatic line accessories for servicing. Locate upstream from all other pneumatic line accessories.

Fluid Line

• Fluid filter (Y-Strainer) (included in G): with a 60 mesh (250 micron) stainless steel element to filter particles from the fluid before in reaches the pump.

• Fluid shutoff valve (H): shuts off fluid flow.

• Pressure relief valve (J): overload protection.

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

Flush the Equipment , page 13.

Chemical Supply

The pump can be used with supplied legs, or the pump stand can be bolted to a wall or skid by the attached bracket.

If you have an application, or mounting configuration, that requires installation in a manner different than

depicted in F IG . 1, please contact your Graco distributor

for assistance.

NOTE: A y-strainer (G) or chemical filter is required before the pump inlet. This will keep any debris from the tank from reaching the pump seals. Fluid filters are available from Graco. See Kits and Accessories on

page 40.

Mount the pump (F) and connect the fluid inlet line (K).

8 3A3948H

Installation

Connect Pneumatic Supply

Install the pneumatic regulator (E) and gauge to

control the inlet pressure. See Models on page 3 for

your model’s maximum pneumatic pressure.

NOTE: If less than 100 psi supply pressure is used, the pump’s maximum output pressure will be decreased proportionally. See

Minimum Pneumatic Pressures by

Fluid Plunger Size and Outlet Pressures on page 10.

Minimum Pneumatic Pressure can be found by first finding the table that corresponds to the plunger size. Next, using the column that corresponds to the pneumatic motor size, find the row equal to or slightly greater than the outlet pressure of the pump. The value is the Minimum Pneumatic Pressure required to achieve the fluid outlet pressure.

Install a pneumatic line filter (C) to keep debris from affecting pump performance and to increase pump life.

NOTE: Keep the needle valve knob closed at this point to keep the pump from operating without fluid, which minimizes seal wear.

Attach a pneumatic line to the 1/4 in. female NPT port (116) on the needle valve.

Route Exhaust to Remote

Location

Replace the 3/8 in. npt muffler (215) with a pneumatic line to route exhaust to a remote location.

Connect Chemical Outlet

Connect a 1/4 npt(f) fluid line from the outlet check valve (M) to the injection point.

NOTE: On “H” outlet connection configurations

(PCI-xxx-xxH-xx-x), the 1/4 npt(f) fitting is replaced with an HiP HF4 fitting.

Install a fluid pressure relief valve (J) on the outlet side of the pump.

NOTE: A pressure relief valve is available from Graco and can be connected back to the tank or directly to the inlet side of the pump. See Kits and Accessories on

page 40.

In the event of an injection line blockage, to reduce the risk of skin injection and damage to the pump, ensure the pressure relief valve is set at or below the maximum working pressure of the pump.

Set the pressure relief valve at or below the maximum working pressure of the pump.

Connect a 10-32 UNF fluid outlet from the prime/bleed valve (21) to the fluid source or waste reservoir.

NOTE: On “H” outlet connection configurations

(PCI-xxx-xxH-xx-x), the 10-32 fitting is replaced with a

1/16 in. NPT(F) fitting.

NOTICE

Due to the operational design of the pneumatic valve,

3.5% of the exhaust is not recoverable, and will vent to atmosphere.

Operation

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

Flush the Equipment

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection and splashing fluid, follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or servicing the equipment.

NOTE: Always discharge fluid into an approved container or location.

Shut off all fluid and pneumatic lines (A, K, & P) using shutoff valves (H & B).

Use a flathead screwdriver to turn the prime/bleed valve (107) slowly counter-clockwise to relieve pressure. (Use a hex wrench to turn the prime/bleed valve housing (106) on PCI-xxx-xxH pumps. See

Configuration Number Matrix , page 4.)

Slowly disconnect fluid lines (K & P) from check valves (L & M).

To avoid fire and explosion, always ground equipment and waste container. To avoid static sparking and injury from splashing, always flush at the lowest possible pressure.

• Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.

Follow the Pressure Relief Procedure .

Connect inlet to the supply source of the flushing fluid.

Connect outlet to a waste reservoir.

Run the pump until the dispensed fluid is predominately flushing fluid.

Follow the Pressure Relief Procedure .

3A3948H 13

Operation

Prime the Pump Calibrate Chemical Dosage

Verify all connections and fluid lines are tight.

In order to prime the pump, turn the prime valve

(107) counter-clockwise.

NOTE: The pressure regulator and inlet pneumatic needle valve both effect the pump cycle rate. After inlet pressure is set, the needle valve can serve as a speed control.

Adjust pneumatic regulator to desired pressure. See

Minimum Pneumatic Pressures by Fluid Plunger

Size and Outlet Pressures on page 10.

Open bleed-type pneumatic valve. Slowly turn pump needle valve counter-clockwise, increasing air/gas flow to the pump.

Begin the process by setting the pump to an estimated setting of the flow rate. See

Baseline Chemical Dosage Settings , page 16, for tables of cycles

per minute (CPM), and corresponding gallons per day (GPD) and liters per day (LPD).

Follow the instructions provided with your calibration gauge in conjunction with the

Baseline Chemical

Dosage Settings on page 16.

Adjust the cycle rate with the inlet pneumatic needle valve and/or the pressure regulator.

Repeat the test procedure to verify your changes.

Repeat as necessary until the desired flow rate is achieved.

NOTICE

Pump runaway may occur if the needle valve is opened too far for pressure settings, causing damage to the packing seals (103).

Keep the pump cycle rate less than 1 cycle every 3 seconds. The pump is primed when discharge from the prime valve (107) has transitioned from air, to bubbly liquid chemical, to pure liquid chemical.

Close the prime valve (107) tightly and verify that fluid has stopped draining from the port.

Operation

3A3948H 17

Maintenance

Preventive Maintenance

Schedule

The operating conditions of your particular pump determines how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your pump.

Tighten Threaded Connections

Check that all threaded connections are tight at routine intervals.

Tighten Packings

The packings included in your pump have the ability to be adjusted to stop leaks that develop when the seals are worn. If a leak develops in the pump’s fluid section, tighten the packing nut clockwise by 1/16th of a turn, or lower, until the leak is eliminated. The life of the packing can be affected by over-tightening the packings. If the packing nut needs to be tightened repeatedly after short intervals, replace the packing.

Storage

If the pump is going to be stored for long periods, it is recommended that the pump be flushed with a light-weight oil or rust prohibiter to protect pump components. Store the pump with protective fluid inside whenever possible.
