Page 17: Leak Detect
LEAK DETECT OVERVIEW The leak detect feature alerts if solution is present in the pump head by sensing the conductivity of the liquid. The sensitivity is factory preset to distinguish between water and common water treatment chemicals. Always calibrate the sensitivity with the chemical and chemical concentration utilized in the application to reduce the number of false tube leaks. - Page 18 LEAK DETECT continued CALIBRATE THE LEAK DETECT SENSITIVITY page 1 of 2 TO BE INSTALLED AND MAINTAINED BY PROPERLY TRAINED PROFESSIONAL INSTALLER ONLY. READ MANUAL & LABELS FOR ALL SAFETY INFORMATION & INSTRUCTIONS. Turn off water system, disable all pumps and depressurize the system before performing installation.
- Page 19 LEAK DETECT continued CALIBRATE THE LEAK DETECT SENSITIVITY page 2 of 2 9. Turn the potentiometer an additional one full turn counterclockwise. 10. Remove sponge and thoroughly clean the solution off pins and confirm they are dry. IMPORTANT: Confirm there is no chemical residue remaining on the leak detect pins and bracket.

INSTALLATION ADDITIONAL SAFETY INSTRUCTIONS NOTICE: Indicates special instructions or general mandatory action. Read all safety hazards before installing or servicing the pump. The pump is designed for installation and service by properly trained personnel. Use all required personal protective equipment when working on or near a chemical metering pump. - Page 21 INSTALLATION continued MOUNT PUMP Recommended mounting is vertical with pump head pointed downward or horizontal sitting on motor base. Select a dry location (to avoid water intrusion and pump damage) above the solution tank. Best recommended location is above the solution tank in a vertical position with the pump head pointed downward.

Use outside of solution tank as a guide to cut proper length of suction line ensuring it will be 2-3" above the bottom of solution tank. Allow sufficient slack to avoid kinks and stress cracks. Always make a clean square cut to assure that the suction line is burr free.
- Page 24 INSTALLATION continued INSTALL SUCTION WEIGHT TO SUCTION LINE 1. Drill a hole into the bung cap or solution tank lid. Slide the tubing through and secure the weighted strainer to the line. 2. To attach the strainer, push approximately 3.5" of suction line through the cap on the strainer body.

Page 31: Tube Replacement
TUBE REPLACEMENT SAFETY INFORMATION RISK OF CHEMICAL EXPOSURE To reduce risk of exposure, check the pump tube regularly for leakage. At the first sign of leakage, replace the pump tube. To reduce risk of exposure, the use of proper personal protective equipment is mandatory when working on or near chemical metering pumps. - Page 32 S34 TUBE REPLACEMENT continued PREPARATION 1. Follow all safety precautions prior to tube replacement. 2. Prior to service, pump water or a compatible buffer solution through the pump and suction and discharge lines to remove chemical and avoid contact. REMOVE THE PUMP TUBE 1.
- Page 33 S34 TUBE REPLACEMENT continued REMOVE THE PUMP TUBE continued 6. Collapse the roller assembly. Hold the pump body securely, use the tube housing cover as a wrench and quickly (snap) rotate the cover counterclockwise to collapse the roller assembly. The tube will no longer be pressed against the tube housing wall.
