Maintenance

Water Motor

1. Do not let unit freeze.
2. Periodically clean or replace chemical hose (hose between pump & water motor) and connectors. Chemical buildup will cause the unit not to pump.
3. If chemical pump becomes hard to remove from bottom of water motor, clean inside of opening on bottom cap of water motor with tooth brush & white vinegar.

Chemical Pump

1. Clean pump after use by running clean water through the pump for 5 minutes, or by removing the pump and hand cleaning individual parts.

Other

1. Water is always a factor with the life of any injector. If you know you have problem water, an in-line filter before the injector is a wise investment.
2. Keep your stock solution bucket clean of foreign particles and trash.
3. Keep the suction hose filter off the bottom of the stock solution bucket, insoluble particles may cause clogging and accelerate wear.

Removal & Installation

Fixed Pump Mounting template

1. In each box provided a white envelope containing four screws. The marked envelope is used as a template to mount the unit at any stationary surface, or to a post.
2. Tighten the screws until the head is about 1/8”away from the surface. The brackets on the back of the unit will slide down between the screw head and the surface.

Starting the Unit

1. Be sure chemical pump is locked into the bottom of the water motor. (1/4 turn to the right)
2. Open valves (B) and (C)
3. Close valve (A)
4. Open air vent until all trapped air is released

Stopping the Unit

1. Open valve (A), then close valves (B) and (C)

Removal

1.  Make sure the water is turned off, and water pressure in the water motor is released – this is done by loosening the Air Vent (pressure relief valve) on the top of the water motor and turning off the water at both gate valves.
   Note: Do Not Remove Air Vent

2. Turn pump counter clockwise 1/4 turn, then pull down.
   Note: Always disconnect hose from pump before removing.

Installation
Note: Lubricate “O” rings on pump housing with any biodegradable lubricant when pump is removed from motor.

1. Make sure the pump stem is pulled all the way out (about 2”). Push the pump up into the water motor, and turn 1/4 turn clockwise, port to front.
   Note: The guide slot must be aligned to fit into the key on the inside of the water motor.

2.  After installing pump into bottom of water motor – loosen Jaco nut on pump and insert hose into fitting. Retighten Jaco nut.

Adjustable Pump Installation

1. Lubricate “O” rings on pump housing with any biodegradable lubricant before pump is installed into motor.

2. Make sure the pump stem is pulled all the way out (about 2”). Remove the white shipping clip prior to installation.

3. Push the pump up into the water motor, pins inside the water motor will engage with the grooves in the “Pump Body”. Turn pump 1/4 turn clockwise. The slot in the “Locator Collar” will mate with the “Square Projection” on the “Water Motor”.
   Note: Depressing the “Buttons” on each side of the “Locator Lock” will allow the “Locator Collar” to rotate 180 degrees to allow installation with chemical injection on the right side. If the slot in the “Locator Collar” does not mate with the “Water Motor”, depress the “Buttons” and rotate the “Locator Collar” until the “ Groove” mates with the “Water Motor”.

4. Rotating the “Dilution Ring” changes the dilution ratio. Rotate the “Dilution Ring” either direction until the correct dilution is set.

5. Rotate the “Lock Ring” clockwise to lock the dilution setting. Rotating the
   “Lock Ring” counter-clockwise allows the dilution to be changed.

6. After installing pump into bottom of water motor – loosen Jaco nut on pump and insert hose into fitting. Retighten Jaco nut.

Troubleshooting

Chemical pump

with a rebuild kit.
Sleeve may be broken or extremely worn.| Replace sleeve.
Pump cap is loose.| Hydro Systems ships all units and pumps with the pump caps loose. At installation caps need to be tightened to a minimum of 20 inch pounds of torque (hand-tighten only).
Pump stem is not engaged into the piston clip in water motor.|

• Remove pump, check for a broken or worn pump stem at tip
• Pump stem must be pulled out completely (approx. 2 in.) before being inserted into the bottom of the water motor

Piston clip may be broken or worn on the inside of the water motor.| This is an extremely rare occurrence but if the pump stem was not pulled out when initially installed this could cause excessive wear of the piston clip. The water motor must be sent to an authorized repair center or Hydro Systems for repair.
Chemical solution is drawn up in the suction hose, but then falls back down.| Vacuum leak.|

• Check valve may need cleaning or replacing.
• Tighten pump cap to recommended 20 inch pounds of torque.
• Check suction hose to insure a tight fit with clamp in place.
• Prime pump by hand and verify that chemical solution stays up in the suction hose.

Adjustable Pump| Motor clicks, but chemical is not drawn up into the suction hose.| Large “O” ring on lower seal is worn or damaged.| Replace pump stem.
Pump stem is not engaged into the piston clip in water motor.|
