INGROUND POOL SKIMMER INSTRUCTIONS
CMP 25100, 25120, 25140 SKIMMERS
OPERATION FOR ALL SKIMMERS
Water is pulled through the skimmer by the suction of the pump. Water flow carries
floating debris into the skimmer where it is collected in the skimmer basket. The
floating weir creates a better water flow and increases efficiency. The water level of the
pool should be kept at least 2" above the bottom of the mouth of the skimmer to ensure
proper operation. To adjust the skimmer flow rotate the diverter plate on the float valve
or in the skimmer until the desired flow is achieved. In the instance of multiple
skimmers, rotate the diverter plate in each skimmer over the pump port to restrict and
balance the flow from each skimmer. To vacuum the pool, remove the float valve and
close the diverter plate over the main drain. Install the skimmer vacuum in the skimmer
and connect to vacuum hose.
OPERATION WITH DIVERTER PLATE
For full flow, rotate diverter plate completely open. To adjust flow, rotate over the
pump port until desired flow is achieved. To vacuum, either remove cover and basket.
Screw the hose adapter into the pump port. Fill hose with water and insert over the
hose adapter. OR insert the skimmer vacuum into skimmer on top of the basket.
OPERATION WITH FLOAT VALVE
If the water level drops below the mouth of the skimmer or if the basket is clogged and
no water can flow through it, then the float valve will automatically close over the flow

ports. This diverts all water flow to the pump from the main drain line. It prevents
possible air lock. When the pump is shut off the float valve will float back to the top of
the cavity, allowing normal operation to resume.
TO SWEEP/BRUSH: Divert all suction to
the main drain by holding the weir above normal operating level and allowing the float
to snap shut. Or remove the float valve assembly, close the diverter plate, and replace.
To reset the float valve assembly, turn off the pump for 10-15 seconds. The float valve
will rise to the top of the skimmer cavity.
TO VACUUM: Remove cover, basket and float
valve assembly. Screw the hose adapter into the pump port, fill the hose with water, and

insert over adapter. OR insert the skimmer vacuum into skimmer on top of the basket.

OPERATION WITH FLOAT VALVE & EQUALIZER CHECK VALVE
The Equalizer Check Valve Assembly screws into the main drain port and is used in
tandem with the float valve assembly. If the water level drops or if flow is restricted,
the float valve will snap down and the equalizer valve will open. This diverts all flow to
the pump from the equalizer line and prevent airlock in the pump. When the pump
is turned off, and the problem is corrected, the float valve will rise to the top of the
skimmer cavity and the equalizer will close, allowing for normal operation to resume.
TO VACUUM: Remove cover and float valve from the selected skimmer. Place the
vacuum plate over the basket. Fill the hose with water and insert over the hose adapter.
Adjust the flow from the other skimmers until desired suction is achieved through the
vacuum.
