Clamp Installation
Follow these instructions exactly
to prevent the lid
from separating during system startup or operation.
1. Turn off the pump and any automatic controls.
2. Open the manual air relief valve and turn
counterclockwise until it snaps into the full open
position. Wait until all pressure is relieved before
assembly, disassembly, or servicing.
3. Be sure the O-ring is clean and in position on the
lower tank half. Place the filter lid onto the lower
tank half so the O-ring fits in between the tank
halves.
4. Hold the ends of the filter clamp apart and place
over both upper and lower tank flanges. Bring the
ends of the filter clamp together.
5. Insert the T-bolt through the other side of the clamp
and hold together.
6. Place the small washer onto the T-bolt.
7. Place the larger washer and spring onto the barrel
nut then place onto T -bolt and tighten the nut by
hand. Be sure filter clamp is fully engaging both
tank flanges.
8. First tighten the nut using a 7/8 in. wrench and
then tap around the outside of filter clamp with a
rubber mallet (or similar tool) multiple times around
the entire clamp to fit the clamp properly. Continue
to tighten only until the spring coils touch.
Note:
The clamp is installed correctly only when
the spring coils remain touching after tapping the
clamp (See
Figure 3
). If the clamp spring coils do
not touch after tapping then continue to tighten the
nut as instructed above in Step 8.
9. Continue on to
System Restart Instructions
on
page 5.
Note:
Check the spring coils at least once a
month to ensure proper tension. If spring coils
do not touch, turn the system off to tighten the
nut and tap filter clamp until the coils touch, and
restart.

FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (e.g., clamp, pump, filter, valve(s), etc.), is serviced, air can enter the system and become
pressurized. Pressurized air can cause the lid to separate which can result in severe injury, death, or property damage.
To avoid this potential hazard, follow these instructions:
1. Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of the clamp or any other
service of the circulating system: (A) Turn the pump OFF and shut OFF any automatic controls to ensure the system is NOT
inadvertently started during the servicing; (B) open the manual air relief valve; (C) stand clear of the filter; (D) wait until all
pressure is relieved.
2. Whenever installing the filter clamp FOLLOW THE CLAMP INSTALLATION INSTRUCTIONS EXACTLY.
3. Once service on the circulating system is complete FOLLOW SYSTEM RESTART INSTRUCTIONS EXACTLY.
4. Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., clamp, pressure gauge, valve(s),
o-rings, etc).
5. Be sure that the filter is properly mounted and positioned according to instructions provided.
