Installation of Remote Pilot Air Lines
1.
Refer to Parts Drawings. Connect air line to pump as in preceding steps.
2.
Connect 1/4 in. O.D. tubing to push type connectors (14) on air motor of pump.
Air Line
WARNING
A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury, including splashing in the eyes or on the skin, injury from moving parts, or contamination from hazardous fluids. See Fig. 2.
NOTE: by replacing the push type connectors, other sizes or types of fittings may be used. The new fittings will require 1/8 in. npt threads.
3.
Connect remaining ends of tubes to external air signal, such as Graco’s Cycleflo (P/N 195264) or
Cycleflo II (P/N195265) controllers.
NOTE: the air pressure at the connectors must be at least 30% of the air pressure to the air motor for the pump to operate.
Fluid Suction Line
1.
Use grounded fluid hoses (G). The pump fluid inlet (R) is 1–1/2 in. npt(f). Screw the fluid fitting into the pump inlet securely.
1.
Install the air line accessories as shown in Fig. 2.
Mount these accessories on the wall or on a bracket. Be sure the air line supplying the accessories is grounded.
a.
Install an air regulator (C) and gauge to control the fluid pressure. The fluid outlet pressure will be the same as the setting of the air regulator.
b.
Locate one bleed-type master air valve (B) close to the pump and use it to relieve trapped air. See the WARNING above. Locate the other master air valve (E) upstream from all air line accessories and use it to isolate them during cleaning and repair.
2.
If the fluid inlet pressure to the pump is more than
25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation.
3.
At inlet fluid pressures greater than 15 psi
(0.1 MPa, 1 bar), diaphragm life will be shortened.
4.
See the Technical Data on page 30 for maximum suction lift (wet and dry).

Fluid Pressure Relief Valve Changing the Orientation of the Fluid Inlet and Outlet Ports
The pump is shipped with the fluid inlet (R) and outlet
(S) ports facing the same direction. See Fig. 3. To change the orientation of the inlet and/or outlet port:
1.
Remove the screws (106) holding the inlet (102) and/or outlet (103) manifold to the covers (101).
2.
Reverse the manifold and reattach. Install the screws, and torque according to the torque notes in Fig. 3.
CAUTION
Some systems may require installation of a pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose. See Fig. 4.
Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambient heat, or when pumping from a cool to a warm area (for example, from an underground tank).
Overpressurization can also occur if the Husky pump is being used to feed fluid to a piston pump, and the intake valve of the piston pump does not close, causing fluid to back up in the outlet line.

Air Exhaust Ventilation
Installation
The air exhaust port is 3/4 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation.
WARNING
FIRE AND EXPLOSION HAZARD
Be sure to read and follow the warnings and precautions regarding TOXIC
FLUID HAZARD, and FIRE OR EXPLO-
SION HAZARD on page 3, before operating this pump.
Be sure the system is properly ventilated for your type of installation. You must vent the exhaust to a safe place, away from people, animals, food handling areas, and all sources of ignition when pumping flammable or hazardous fluids.
Diaphragm failure will cause the fluid being pumped to exhaust with the air. Place an appropriate container at the end of the air exhaust line to catch the fluid. See Fig. 5.
If the muffler (P) is installed directly to the air exhaust port, apply PTFE thread tape or anti–seize thread lubricant to the muffler threads before assembly.
To provide a remote exhaust:
1.
Remove the muffler (P) from the pump air exhaust port.
2.
Install a grounded air exhaust hose (T) and connect the muffler (P) to the other end of the hose.
The minimum size for the air exhaust hose is 3/4 in. (19 mm) ID. If a hose longer than 15 ft (4.57 m) is required, use a larger diameter hose. Avoid sharp bends or kinks in the hose. See Fig. 5.
3.
Place a container (U) at the end of the air exhaust line to catch fluid in case a diaphragm ruptures.

Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the gun or splashing fluid, follow this procedure whenever you:
Are instructed to relieve pressure,
Stop pumping,
Check, clean or service any system equipment,
Install or clean fluid nozzles.
1.
Shut off the air to the pump.
Operation
NOTE: If the fluid inlet pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation.
4.
Place the end of the fluid hose (L) into an appropriate container.
5.
Close the fluid drain valve (J). See Fig. 2.
6.
Close the pump air regulator (C). Open all bleedtype master air valves (B, E).
7.
If the fluid hose has a dispensing device, hold it open while continuing with the following step.
8.
Slowly open the air regulator (C) until the pump starts to cycle. Allow the pump to cycle slowly until all air is pushed out of the lines and the pump is primed.
2.
Open the dispensing valve, if used.
3.
Open the fluid drain valve to relieve all fluid pressure, having a container ready to catch the drainage.
Flush the Pump Before First Use
The pump was tested in water. If the water could contaminate the fluid you are pumping, flush the pump thoroughly with a compatible solvent. Follow the steps under Starting and Adjusting the Pump.
If you are flushing, run the pump long enough to thoroughly clean the pump and hoses. Close the air regulator. Remove the suction tube from the solvent and place it in the fluid to be pumped.
Operation of Remote Piloted Pumps
1.
Follow preceding steps 1 through 7 of Starting
and Adjusting Pump.
2.
Open air regulator (C).
Starting and Adjusting the Pump
WARNING
The pump may cycle once before the external signal is applied. Injury is possible. If pump cycles, wait until end before proceeding.
WARNING
TOXIC FLUID HAZARD
To reduce the risk of serious injury, splashing in the eyes or on the skin, and toxic fluid spills, never move or lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the Pressure Relief
Procedure above before lifting the pump.
1.
Be sure the pump is properly grounded. Refer to
Grounding on page 4.
3.
Pump will operate when air pressure is alternately applied and relieved to push type connectors (14).
NOTE: Leaving air pressure applied to the air motor for extended periods when the pump is not running may shorten the diaphragm life. Using a 3–way solenoid valve to automatically relieve the pressure on the air motor when the metering cycle is complete prevents this from occurring.
Pump Shutdown
2.
Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant on all male threads. Tighten the fluid inlet and outlet fittings securely.
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
3.
Place the suction tube (if used) in the fluid to be pumped.
At the end of the work shift, relieve the pressure.

Notes
Maintenance
Flushing and Storage Lubrication
The air valve is designed to operate unlubricated, however if lubrication is desired, every 500 hours of operation (or monthly) remove the hose from the pump air inlet and add two drops of machine oil to the air inlet.
CAUTION
Do not over-lubricate the pump. Oil is exhausted through the muffler, which could contaminate your fluid supply or other equipment. Excessive lubrication can also cause the pump to malfunction.
Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it. Use a compatible solvent.
Always flush the pump and relieve the pressure before storing it for any length of time.
Tightening Threaded Connections
Before each use, check all hoses for wear or damage, and replace as necessary. Check to be sure all threaded connections are tight and leak–free.
Check fasteners. Tighten or retorque as necessary.
Although pump use varies, a general guideline is to retorque fasteners every two months. See Torque
Sequence, page 28.
