Collection cup: Loosen the screws to flip over the lid, then screws back.
(For safe shipping, the lid would be upside-down in the package.)
Check if O-ring is seal in the groove, and put on the collection cup.
Tighten the screws, but do not over-tighten, or product might be damaged. Install the beckett set.
Install the inlet set. Install the air hoses to connect the beckett set and silencers. Install the drain port, and turn it off.
Use the thread seal tape (sold

For both in-sump installation and external installations, the water level should not be over 1/2 of the main
skimmer body, or the valve be out of function.
The hose clamp is needed for all hose connects, to prevent leaks.
For outlet tubing, you can choose a hose or tube. The tubes likes PVC tubes
would be recommended because it won't be bent and produce resistance.

Plugin the pump, and make sure every part is secured.
Now you can get skimmate wetter/drier by adjusting the water level.
Tips: You can extend the air hose to reduce noise.
When the operation is going well, turn off the outlet valve slowly
(clockwise), until the water level reaches collection cup holder.
( It’s normal if there’s some water inside the injectors in this step. )

For best performance, please clean the collection cup frequently. Use a sponge and warm water to clean it.
(DO NOT USE ANY SOAP OR CHEMICALS TO CLEAN THE COLLECTION CUP).
The beckett and the inlet tube must be clean frequently, due to the air to water interface calcium carbonate
(limescale) builds up to form a very hard white substance. Separate the becketts and the inlet, and disassemble
the becketts to clean.
It may require 2 – 4 weeks for the skimmer to reach maximum performance due to tiny amounts of oil or remnants left from manufacturing. Skimmer performance may be erratic during this
time and be sure to allow ample time for the skimmer to break-in before making adjustments. You can clean the skimmer with warm water to shorten the break-in period.
