Aquastar Pressure Gauge For PLF27000 And PLF35000 Pipeline Filters | PF2011

The OEM Aquastar pressure gauge is supplied with an adjustable boot with two arrows separated by 10 psi. This is to mark the clean filter pressure allowing users to see the pressure rising above the START pressure and to know when the filter should be cleaned.

IMPORTANT: While the Pressure Gauge Boot is very helpful, it can be moved without your knowledge so it is important to also record the new filter start-up filter pressure on the front of this manual for future reference.

How to read the pressure gauge
When reading a bouncing pressure gauge, estimate the middle of the bouncing needle and then use that as the filter’s current operating pressure.

With a new or clean filter cartridge installed, configure the recirculation system valves and pump so the system is operating at the design filtration flow rate. After confirming the system is operating properly, use both hands to rotate the Pressure Gauge Boot so the START Arrow is pointing at the operating pressure gauge needle. A bouncing pressure gauge is normal, aim the Boot’s Start Arrow towards the middle of the bouncing needle’s operating range.

For best results, clean your filter BEFORE pressure reads 10 psi higher than the original starting pressure. Your filter pressure reading will increase as it removes debris from your pool. This buildup of pressure will vary due to different bathing loads, temperature, weather conditions, etc. Check your filter pressure frequently, typically whenever you check your water chemistry and after you clean skimmer baskets.

Check the operation of your pressure gauge in the following manner:
• The pressure gauge should go to zero (0) when the pump is OFF and the filter Manual Air Relief Valve is OPEN.
• The pressure gauge should indicate pressure when the system is operating properly, EXCEPT when a variable speed pump is operating at a very low speed.

• Apply two or three wraps of Teflon tape to the pressure gauge ¼-inch threads.
• Carefully thread the gauge into the ¼-inch NPT hole in the filter Lid. Turn the gauge by hand until snug and then use a 9/16-inch or 14mm box-end wrench to finish tightening the gauge so it is facing a readable direction.
• DO NOT OVER TIGHTEN.
• When the filter is started for the first time, the Boot will need to be adjusted so the START Arrow points at the operating gauge needle when the filter is new and clean, and with the pump and recirculation system configured and operating at the design filtration flow rate.
