Rola-Chem 554000 ORP/pH Digital Controller - Manual (Page 4)

1.0 Safety Instruction
A-
WARNING: Do not shut down circulating and control system immediately after using
pool, spa or hot tub. Systems must operate until water chemistry is stable. Systems must
be restarted before water chemistry is out of NSPI recommended ranges or water
chemistry must be manually corrected.
B-
WARNING: Removing power from circulating pump must also remove power from the
controller. Provide a properly located outlet controlled by the circulating pump circuit.
C-
WARNING: Pool water must be balanced and stabilized before operating this controller.
(See ‘READ ME FIRST’ document for further information.
D-
WARNING: Use a device such as a flow switch to shut-off power from the controller 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.
E-
WARNING: Controller uses microprocessor.
Wireless communication equipment or other electrical operated devised operated in close
proximity may cause inadvertent actuation of chemical feed pumps.
F-
WARNING: Risk of electric shock.
Connect power cord to ground-fault circuit interrupter (GFCI). Contact qualified
electrician if you can not verify that your installation meets local electrical codes,
including grounding of water system components.
G-
WARNING: Do not bury cords.
Locate cord to minimize abuse from lawn mowers, trimmers and other equipment.
Replace damaged cords immediately. Do not use extension cords.
H-
WARNING: Do not install within an outer enclose or beneath skirt of tub or spa unless so
marked.
2.0 Description and Specifications
2.1 General Description
The controller is a microprocessor-based chemical automation system, which continuously
monitors and maintains the pH balance and sanitizer level in a swimming pool or spa.
The pH and sanitizer level (ORP) are displayed using sun-bright seven-segment light emitting
diodes. The pH and ORP levels are continuously monitored and displayed on the controller’s
