For Installation of Electrical Controls at Equipment Pad
(ON/OFF Switches, Timers and Automation Load Center)
Install all electrical controls at equipment pad, such as on/off switches, timers, and control systems, etc. to allow the
operation (startup, shut-down, or servicing) of any pump or filter so the user does not place any portion of his/her body
over or near the pump strainer lid, filter lid or valve closures. This installation should allow the user enough space to stand

Failure to do so could result in serious injury or death to serviceman, operator users or others due to electric shock.

FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (e.g., clamp, pump, filter, valve(s), etc.), is serviced, air can enter the
system and become pressurized. Pressurized air can cause the lid to separate which can result in severe injury,
death, or property damage. To avoid this potential hazard, follow these instructions:
1. Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of
the clamp or any other service of the circulating system: (A) Turn the pump OFF and shut OFF any
automatic controls to ensure the system is NOT inadvertently started during the servicing; (B) open the
manual air relief valve; (C) wait until all pressure is relieved.
2. Whenever installing the filter clamp FOLLOW THE FILTER CLAMP INSTALLATION INSTRUCTIONS
EXACTLY.
3. Once service on the circulating system is complete FOLLOW SYSTEM RESTART INSTRUCTIONS
EXACTLY.
4. Maintain circulation system properly. Replace worn or damaged parts immediately, [e.g., clamp,
pressure gauge, valve(s), o-rings, etc].
5. Be sure that the filter is properly mounted and positioned according to instructions provided.
