HAZARDOUS PRESSURE/CHEMICAL EXPOSURE
Use caution and bleed off all resident system pressure prior to attempting service or installation.
Use caution when disconnecting discharge line from pump. Discharge line may be under pressure. Discharge line may contain chemical.
To reduce risk of exposure, the use of proper personal protective equipment is mandatory when working on or near chemical metering pumps.
NOTICE: Indicates special instructions or general mandatory action.
NOTICE: Pumps are installed with a ball check valve allowing the extension tip to be installed in the center of the pipe directly in the flow of water to help reduce deposit accumulation.
1. Turn metering pump off and unplug cord. Disable any water pump or auxiliary equipment's electrical supply.
2. Depressurize system and bleed pressure from pump discharge line.

(1, 2 or 3). If we do not have any images
4. Unscrew the top fitting (check valve body) to disassemble. The bottom fitting (injection fitting with arrow) should remain attached to the pipe.
to add, I will adjust spacing.
5. Remove the spring, seat, ball and O-ring from the check valve body. Inspect and replace components as needed. Be careful to not stretch or damage the spring.
6. Insert a #2 Phillips head screwdriver through injection fitting into the pipe to locate or break up accumulated deposits. If screwdriver cannot be inserted, drill the deposit out of the injection fitting. DO NOT drill through the opposite pipe wall.

7. Replace discharge line if cracked or deteriorated. If the end is clogged, cut off the calcified or blocked section of discharge line.
8. Reassemble the ball check valve.
9. Replace the 3/8" connecting nut and reconnect the discharge line into the ball check valve. Insert the discharge line into the base until it stops, approximately 3/4".
10. Tighten the 3/8" connecting nut finger tight while firmly holding the tube fitting then wrench tighten the 3/8" connecting nut one additional half turn. If leak occurs, gradually tighten the 3/8" connecting nut as required.
11. Enable any water pump or auxiliary equipment's electrical supply and pressurize the water system.
NOTE: The roller assembly must be expanded so the tube is pressed against the tube housing wall.
12. Put the metering pump back in service and inspect all connections for leaks.

DISASSEMBLY
1. Turn pump off and unplug the power cord.
2. Depressurize and disconnect the suction and discharge lines.
3. Open the latches on both sides of the head. Carefully fold latches back to prevent contact with the cover.
For CE pump only: Remove the safety screw on cover.
Remove the tube housing cover and flip to use as a tool in the next step. Figures A & B
4.
5. Align the center of the inverted cover with the center of the roller assembly so that the three holes on the face of the cover align with the three knurled lugs
on the roller assembly. Position the cover feet near the tube fittings at approximately 10 o'clock. Figure C
NOTE: The roller assembly must be collapsed to remove the tube.
6. Hold the motor securely with one hand. With the other hand, hold the
tube housing cover with your forefingers inside the top lip of the cover.
Figure D Use the cover as a wrench and with your palm quickly (snap)
rotate the cover counterclockwise to collapse the roller assembly. The
tube will no longer be pressed against the tube housing wall. Figure D
7. Remove and discard the pump tube.
8. Remove the roller assembly.
9. Remove the tube housing.

INSPECTION
1. Use a non-citrus all-purpose cleaner to clean any residue from the tube housing, cover and roller assembly.
2. Check the housing and cover for cracks and replace if cracked.
3. Inspect the rollers of the roller assembly to ensure that they turn freely and are not worn. Figure E Replace if rollers are seized or worn.
REASSEMBLY
1. Ensure the power to the pump is off and the pump is unplugged.
2. Install the tube housing.
3. Apply AquaShield
4. Install roller assembly.
5. Place the new tube in the pump head. Use your fingers to center it over the rollers.
IMPORTANT! DO NOT twist the tube during installation. To ensure it doesn't twist, keep the tube
positioned so the printed description stays aligned along the length of the tube. Figure F
6. Place the tube housing cover (feet first) on the tube housing, affix the front latches to the cover lip and then
press the latches back to secure. Be sure the cover is seated with the sleeve bearing on the shaft and is
flush with the housing before latching. Figure G
7. With the cover latched, plug the pump in and run the pump. Allow the pump to run with the roller assembly
in its collapsed position for approximately four minutes to relax the tube.
8. Turn the pump off and disconnect the power.
9. Remove the tube housing cover and flip to use as a tool in the next step. Figures H & I
10. Align the center of the inverted cover with the center of the roller assembly so that the three holes on the face of the cover align with the three knurled lugs
on the roller assembly. Position the cover feet near the bottom. Figure J
NOTE: The roller assembly must be expanded so the tube is pressed against the tube housing wall.
11. Expand roller assembly. Hold motor securely, use the cover as a wrench and quickly (snap) rotate the roller assembly clockwise to expand the roller
assembly. Figure K The tube will be pressed against the tube housing wall. Figure L
12. Place the tube housing cover (feet first) on the tube housing, affix the front of the latches to the cover lip and then press the latches back to secure. Be
sure the cover is seated with the sleeve bearing on the shaft and is flush with the housing before latching. Figure M
13. Inspect the suction and discharge lines, point of injection, and check valve for blockages. Clean and/or replace as required. Failure to do so may lead to
poor pump performance, including shortened tube life. Reference your pump owner's manual for details.
14. Reconnect the suction and discharge lines using the 3/8" connecting nuts.
15. Turn the pump on and verify operation.
