OPERATION
The following sections describe system requirements, the pre-startup check, dry testing procedure, quick start
instructions, loading/recharging media, filtration mode and PowerBump sequence.
System Requirements
•
Water supply
•
Air supply: Pressure should be a minimum of 90 psi (6.2 Bar)
•
17 lb.(7.7 kg) of perlite (EWT Part Number: 1000-5852)
NOTE
Defender® filters are designed to operate with perlite media. Use of any other media may compromise filter performance.
NOTE
To drain the system, isolate the filter unit from the pool and then open drain valve V9. Vent valve F6 can be opened to increase the
drain rate.
Pre-Startup Check
NOTE
All plumbing and valving must be installed per the filter schematic. Refer to
1.
Verify power is supplied to the following items prior to scheduling a start-up:
•
Compressor
•
Control Panel is wired (Refer to Installing the Control Panel and Filter Regulator)
•
Set the filter/regulator to 90 PSI (6.2 Bar).
•
Pump rotates in the proper direction and is ready to run
Performing a Dry Test
2.
With the pump off, connect jumper between terminal 110 (+24V) and terminal 205 (NC pump fault signal)
3.
Turn the switch on the Control Panel to Filter Mode and then press the Bump button
4.
Ensure all valves transition smoothly without slamming open or closed (Refer to Adjusting the Pneumatic Actuators)
5.
Confirm that the valve states correspond to Figure 10 in all modes.
6.
Turn the switch on the control panel to OFF
7.
Remove the jumper and proceed with startup.
Check for air leaks at the tubing connections. If leaks occur:
1.
Turn the compressor off.
2.
Remove the tubing. Verify it is cut square and free of defects.
3.
Reinstall the tubing. Pull to ensure it is connected securely.
If leaks still occur:
The tubing might be the incorrect OD (outer diameter). All tubing is to be imperial and 0.5 inch O.D.and 0.25 inch.O.D.
