1. Use ONLY ICF system components: Lock Ring unit doing assembly, metal-reinforced seal. Non-tighten lock
ring component may fail in use and cause explosive component separation. Verify that upper and lower filter
bodies are properly secured with the filter body locking ring unit. Make sure tightening enough the Lock Ring
to the filter's upper and bottom body. Verify that the filter manual air relief valve is in the LOCK position, and
no filter components are missing, damaged, or not genuine ICF filter components.

3. Open all system valves to allow water from the pool to the filtration system and from the filter to return to
the pool.
4. Place the air relief valve in an OPEN position.

Pool and spa circulation systems operate under high pressure. When any
part of the circulating system (i.e. lock ring, pump, filter, valves, etc.) is
ser viced, air can enter the system and become pressurized. Filter tank Lid
and pre-filter cover must be secured to prevent violent separation. Place
the pre-filter / filter air relief valve in an open position and wait for all
pressure in the system to be relieved before removing the lib from access
to the basket for cleaning.
3.2 STARTING PUMP
Stand clear of pump during start-up
When starting the system pump, do not stand over or near the filter. If water leakage appears at the lock ring.
Turn off all system circulation pumps and all electrical power immediately. Do not return to the filter until all
water leakage has stopped.
Only return to filter to close air relief valve when water came out.
