1.15 CAUTION! This pump is for use with permanently installed pools and may also be used with hot tubs
and spas. Do not use with storable pools. A permanently installed pool is constructed in or on the ground or in
a building such that it cannot be readily disassembled for storage. A storage pool is constructed so that it is
capable of being readily disassembled for storage and reassembled to its original integrity.
1.16 CAUTION! --- Service tubing regularly, especially when refilling chemical container. See operation
instruction.

3. INSTALLATION:
Tools required – Phillips screwdriver & Adjustable wrench
23/32” drill & ½” pipe tap (NPT) or 7/16” drill & ¼ “ pipe tap(NPT)
1) Install the ROLA-CHEM pump in an area protected from natural elements (sun, rain, freezing, etc.).
Environmental effects may increase required service and maintenance.
The inlet side of the pump must be above the incoming liquid and the chemical container.
Flooded suction is not required or recommended.
Ensure that the tube can be routed without allowing it to kink.
Do not install directly above the chemical container or other equipment that can be damaged by chemicals.
Wall mounting key slots are provided on the rear of the pump enclosure (6.25“ apart for #10 screws).
Comply with local health codes. Cross connections must not allow undesired chemical treatment.
2) The ROLA-CHEM pump is designed to develop a suction lift of 18 feet and to inject into a pressure line of
up to 30 psi*. Do not exceed these limits.
For chlorine pumps, the use of undiluted swimming pool grade, 15% maximum sodium hypochloride is
recommended. For acid pumps, 32% maximum hydrochloric acid feed may be used. See sizing for dilution.
3) Connect the injection fitting into the line to be treated. This should be after heater. Use pipe tape to seal the
pipe threads.
For installation where pressure is greater than 20 psi, use a check valve as the injection fitting or in-line before
injection fitting. One
3 /
8
barbed check valve and one 3 /
8
barbed inlet x ¼ NPT outlet check valve are included
with standard pumps. Use tubing clamp over tube on barbed ends.
*RC503 maximum dispense line pressure is 25psi.
