Fiberglass Sand Filter Installation and User’s Guide

ENGLISH
Failure to position the Automatic Air Vent inside of the Closure will allow excessive trapped air to accumulate in
the filter. Trapped air and the closure not properly closed can cause the closure to seperate and could cause
severe bodily injury and/or property damage.
10. Pivot the diffuser out of the center of the tank on the TR40, 50, 60, TR60 ClearPro, 100 & 140 by
rotating the diffuser assembly counter clockwise. (NOTE: The multi-diffuser assembly should not be
moved on models TR100HD, TR100C, TR100C-3 and TR140C, TR140C-3. After installing the filter
media as described below, check to make sure the tops on the diffusers are parallel to the top of the
sand bed.) Fill the tank about half full of water. Pour pea gravel first (if used) and then the sand into the
top of the filter at a slow rate so that the impact of the filter media does not damage the laterals. See
Table 2 for the proper amounts of sand and gravel. Fill filter to the proper level to maintain freeboard,
as shown in Table 2. Pivot the diffuser assembly back to its vertical position if it was moved. Be certain
the automatic air vent is protruding into the top of the closure as indicated below in Figure 1. Ensure
that the automatic air vent is in the center of the filter closure. Wash away all sand around the threaded
opening at the top of the tank.
For Threaded Closures
Use care when installing closure. The closure should turn freely in the filter, if resistance to closure
insertion is felt, then slowly remove the closure by turning counter-clockwise. The starting thread of the
tank and closure must engage properly in order to secure the closure.
Do not cross-thread closure.
Failure to install the closure properly can cause the closure to seperate and could cause severe bodily
injury and/or property damage.
For Oval Closures
Use care when installing closure. The closure should be inserted into the tank by placing the small
diameter of the oval closure into the larger diameter of the tank opening. Insert the side of the closure
that does not have the pressure gauge and air bleeder first. The closure will need to be inserted at a
30° angle. Once the closure is inside the tank, it can be rotated 90° and lifted up to seal the tank. The
aluminum bridge with load spring can then be placed over the closure bolt and the hand knob tightened
to load the closure properly. The knob should be tightened by hand only. DO NOT USE A WRENCH TO
TIGHTEN THE KNOB. You could damage the tank or closure and cause a failure by using a wrench.
Failure to install the closure properly can cause the closure to seperate and could cause severe bodily
injury or property damage.
NEVER ATTEMPT TO TIGHTEN OR LOOSEN THE CLOSURE WITH THE PUMP RUNNING. Failure
to follow this instruction can result in the closure seperating and causing severe bodily injury or property
damage.
11. Assemble the pressure gauge and bleeder valve to the closure lid. Clean the lid o-ring and lubricate
with silicone grease such as Dow #33, 40 or GE 300, 623 lubricant. Place the closure lid on the filter
and tighten, making certain the air vent is up inside the dome of the closure.
12. With the plastic wrench, provided with the filter, tighten the closure as tight as possible using two
hands on the wrench handles. As a minimum, the closure
must be hand tight + 1/4 turn.
13. The oval closure that is used on the TR140C-3 and the
TR100C-3 models will need to be installed as described in
the above warning note for oval closures.
14. Assemble piping and pipe fittings to pump and valve. All piping
must conform to local and state plumbing and sanitary needs.
15. Use sealant compounds on all male connections of pipe
and fittings. Use only pipe compounds suited for plastic pipe.
Support pipe to prevent strains on filter, pump or valve.
16. Long piping runs and elbows restrict flow. For best efficiency,
use the fewest possible number of fittings, and large diameter
pipe (at least 2” for TR100 and TR140, at least 3” for TR100C-3
and TR140C-3).
