1. Safety: When installing and using this electrical equipment, basic safety precautions
should always be followed, including:
1.1 WARNING !: To reduce the risk of injury, do not permit children to use this product unless they are
closely supervised at all times 1.2 WARNING !: Risk of electric shock.
Connect only to a grounding type receptacle protected by a ground-fault circuit interrupter (GFCI). Contact
qualified electrician if you can not verify that the receptacle is protected by a GFCI and that your installation meets local electrical codes, including grounding of water system components. 1.3 WARNING !: Risk of electric shock. Do not bury or modify the metering pump cord. Locate cord to minimize abuse from lawn mowers, hedge trimmers, and other equipment 1.4 WARNING !: Risk of electric shock. On cord and plug connected units, replace a damaged cord immediately. 1.5 WARNING !: Risk of electric shock. Do not use extension cord to connect unit to electrical supply; provide a properly located outlet 1.6 WARNING !: Risk of electric shock. Do not install within an outer enclosure or beneath the skirt of a hot tub or sap unless so marked. All instructions must be in accordance with appropriate electrical codes. 1.7 WARNING !: Risk of electric shock/pinching/chemical exposure. Remove power sources or lockout circuit prior to performing maintenance on metering pump. Pumps are usually timer controlled and can start at any time. 1.8 WARNING !: Risk of Chemical Overdose/Exposure. Removing power from circulating pump must also remove power from the chemical injection pump. Provide a properly located outlet controlled by the circulating pump circuit. 1.9 WARNING !: Risk of Chemical Overdose/Exposure Use a devise such as a flow switch to shut-off power from the from the chemical injection pump in the event of pool pump or circulation failure. It is not safe to automatically dispensed chemicals into a circulating system that is not running. 1.10 WARNING !: Risk of Chemical Overdose/Exposure Minimize amount of chemical on site that is available to dispense. Size the feeder and container to pool/spa capacity. Dilute chemical for small bodies of water. 1.11 WARNING !: Risk of Chemical Exposure De-pressurize the system prior to connecting or disconnecting the metering pump. 1.12 CAUTION ! :Wear protective clothing, gloves and safety glasses at all times when working on or near the metering pump. 1.13 CAUTION !:Install the metering pump and chemical containers in a ventilated secured location. Protect children, pets, and property from chemical hazards. Containment and/or wash down capability must be in accordance with local regulations and chemical suppliers’ instructions. 1.14 CAUTION !: Read and follow all instructions supplied with the chemical being fed. User is responsible for determining the compatibility of the chemical with the metering pump. Consult supplier of chemical if use and handling instructions are not available.

Crystal buildup is seldom a problem with ROLA-CHEM pumps. However, it may be necessary to flush the pump
hose and tubing. Use plain water or a weak solution of muriatic acid (1/2 pint muriatic acid to one gallon of water).
CAUTION !: Always add acid to water; wear protective clothing, gloves, and safety glasses.
CAUTION !: System pressure must be removed prior to releasing the tubing to prevent backflow. A check valve
may be used at the point of injection to prevent backflow, then the tubing assembly can be disconnected at its connection to the check valve and it will not be necessary to plug the injection fitting hole.
Additional preventative maintenance may be required in harsh environments. Strong chemicals and chemical
vapors may cause corrosion of metal components. Inspect pumps for corrosion to exposed metal components. For pumps utilizing timer functions, replacement of the timer/pot assembly is recommended after 5 years.

Sizing chart is only a guide and is based on Rola-Chem or equivalent pumps using 10.5+ % Sodium Hypochlorite
and Muriatic strength Hydrochloric Acid. When feeding acid diluted 9:1, the acid pump may be the same size as the chlorine (NaHOCl) pump. **Where ‘SAME’ is specified, dilute acid 4:1 to 9:1. Warning!Only add acid to water (i.e. fill tank with 4 gallons of water then add gallon of acid). Consider diluting chemicals for small bodies of water. Actual pump size may vary when diluting chemicals, size pumps based on dilution ratio and available pump sizes.
Pump size must be in compliance with local health codes. When in doubt about pump size or if different brand
feed pumps are used, consult your supplier or Rola-Chem. Rola Chem Manual 2017*RC103 pumps have been successfully used on pools up to 240,000 gallons (RC 503 pumps to 500,000 gallons). Rola Chem Manual Pdf
Caution! Erosion feeders must also be sized to body of water, refer to appropriate sizing data from
feeder manufacturer.
