8.
Install the pressure gauge (supplied with the filter) into the marked hole in the lid, using Teflon tape on the gauge
thread.
9.
If the filter is installed below water level, isolation valves must be installed on the inlet & outlet to enable the filter to be
dismantled for cleaning without the loss of water from the pool or spa.
10.
It is recommended that a 3 way valve be installed on the return line to allow draining of water from the pool or spa
when necessary.
11.
The maximum working pressure of this filter is 50 PSI / 345 KPA. Never subject this filter to pressure in excess of the
amount, even when conducting hydrostatic pressure testing. Pressures above 50 psi / 345 KPA can cause the lid to be
blown off, which can result in severe injury, death or property damage
When performing hydrostatic pressure testing or when testing for external leaks of the completed filtration and plumbing
system, ensure that the maximum pressure that the filtration system will be subject to DOES NOT EXCEED THE MAXIMUM
WORKING PRESSURE OF ANY OF THE COMPONENTS CONTAINED WITHIN THE SYSTEM. In most cases the maximum
working pressure will be stated on each component of the system.
If doubt exists as to the pressure to which the system will be subjected, install an Automatic pressure relief or pressure
regulator in the circulation system for the lowest working pressure of any of the components in the system.
GENERAL FILTER INFORMATION
WARNING
: THIS FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (filter, pump, valves, clamp etc) are serviced, air can enter the system and become
pressurized. Pressurized air can cause the lid to be blown off, which can result in severe injury, death, or property damage. To
avoid this potential hazard, please follow these instructions.
1.
Before repositioning valve(s) and before beginning the assembly or disassembly or adjustment of the clamp or any other
service of the circulating system.
2.
Turn the pump OFF and shut off any automatic controls to ensure the system is not inadvertently started during the
servicing.
3.
Undo the bleed valve in the top of the lid slowly to relief air pressure from the filter until all pressure from the filter is
relieved.
4.
Whenever installing the filter clamp FOLLOW THE FILTER CLAMP INSTALLATION INSTRUCTIONS EXACTLY.
5.
Once the service on the circulating system is complete, FOLLOW THE RE-START PROCEDURE INSTRUCTIONS.
6.
Maintain circulation system properly. Replace worn or damaged parts immediately
7.
Ensure that the filter is properly mounted and positioned according to instructions provided
.
CLAMP INSTALLATION
.
Please follow these instructions exactly to prevent the lid from blowing off during system restart or later operation.
1.
Perform the following steps before working on any part of the circulating system.
2.
Turn the pump off and shut off any automatic controls to ensure that the system is not inadvertently started during
servicing
3.
Open up the air bleed screw located in the lid to remove air pressure and leave open until all air pressure is relieved.
4.
Be certain the o-ring is in correct position in the lower tank half groove, fit the top filter lid carefully over the lower
half of the filter tank ensuring oring stays in position as doing so.
5.
Holding the ends of the filter clamp apart, position the center segment of the filter clamp over both upper and lower
tank flanges. Bring the ends of the clamp together, while ensuring the T-BOLT located correctly in 1 ½ of the clamp.
While holding the 2 halves together screw on the brass nut until you are able to let go of the clamp and it stays in
position.
6.
Begin to tighten the brass nut with a ¾”wrench, tighten the brass nut until the gap between the two clamps is approx. 1
finger width. (5/8”to 3/4”/ 16 – 19mm). DO NOT over tighten beyond this gap specified
