For best results place the skimmer in 22 - 25 cm of water. Please make sure that the skimmer is in 

no more than 25.5 cm of water as the gate valve will not operate properly.
The pump must be completely submerged underwater when in use.
Plug the pump into the power outlet and switch on.

 The main chamber will fill with bubbles; adjust the gate valve until the water (bubble) level is 

where the collection cup meets the neck. If a wet skimmate is preferred slowly turn the gate valve 

clockwise (to close). Otherwise, turn the gate valve anticlockwise for a drier skimmate.

Please open the package carefully and check for damaged or missing parts.

Never connect the AFM Marine PSK-SK5.0 Protein Skimmer (product) to the 
power outlet whilst your hands are wet.
Do not allow the pump to run dry. Keep the pump submerged during operation.
Failure to do so could damage the pump and or cause failure.

Ensure that there is a drip-loop in the pump cord to prevent water running down 

the cord and reaching the plug/power outlet.

Always unplug the product from the power outlet prior to the product 

maintenance. 

While we take great care to keep any contaminates away from our products during 

manufacture please take a moment to clean the protein skimmer before use. 

(only clean your protein skimmer with warm water; never clean with any soap or 

chemicals and use caution when handling as acrylic scratches easily)

For best performance, please clean the collection cup frequently using a sponge and 

warm water.
Regular maintenance of the pump will ensure a long life and maximum performance.

Remover any protective paper backing from the base of the skimmer and any transportation tape 

from the skimmer body.

Insert the vibration absorbing rubber feet into the skimmer base plate and the pump base plate.

Connect the air hose (15mm) from the air intake on the air silencer.

Connect the water outlet of the pump to the main body of the skimmer using the short length of 

38mm air hose.

Install the collection cup into the neck of the skimmer, turning gently clockwise to lock the collection 

cup in position (avoid over tightening).
