Fiberglass Sand Filter Installation and User’s Guide
Failure to operate your filter system or inadequate filtration can cause poor water clarity obstructing
visibility in your pool and can allow diving into or on top of obscured objects which can cause serious
personal injury or drowning.
Clear water is the result of proper ltration as well as proper water chemistry. Pool chemistry is a specialized area
and you should consult your local pool service specialist for specic details. In general, proper pool sanitation
requires a free chlorine level of 1 to 3 PPM and a pH range of 7.2 to 7.6.
Filters should never be tested or subjected to air or gas under pressure. All gases are compressible
and under pressure create a danger. Severe bodily injury or property damage could occur if the filter is
subjected to air or gas pressure.
1. Check carton for any evidence of damage due to rough handling in shipment. If carton or any lter components
are damaged, notify the freight carrier immediately.
2. Carefully remove the accessory package and the lter tank from the carton.
3. Mount the lter on a permanent slab, preferably concrete poured in a form or on a platform constructed of
concrete block or brick. DO NOT use sand to level the lter or for the pump mounting, as it will wash away.
4. Provide space and lighting for routine maintenance access. Do not mount electrical controls over the lter.
One needs to be able to stand clear of the lter when starting the pump. Minimum space requirements may
be found on the large nameplate on the lter.
5. Position lter so that the port locations are in the desired nal positions. Follow valve installation procedures.
6. If you have a Multiport Valve, assemble the valve to the tank, being sure the o-ring on the valve ttings are
in place and are clean. Use a lubricant, applied lightly, such as silicone grease, Dow #33, #40 or GE 300 or
623, or similar product on o-rings and o-ring grooves prior to assembly.
7. If you have a two position slide valve, align the valve with the tank so that the handle is toward the top of
the tank, push valve into ports and turn the valve nuts snugly on the tank ttings. It is not necessary to cinch
the valve nuts to the tank tting beyond hand tightness.
8. The shipping straps used to support the TR100C-3, TR140C and the TR140C-3 multi-diffuser should be
removed before loading sand and gravel in the lter.
9. Sand specications – be certain the proper sand is used as described in Table 2. Before pouring the sand into
the lter, look inside and check the lower under-drain for broken or loose laterals (or ngers), which may
have been accidentally damaged by rough handling during shipment. Replace any broken parts if necessary.
NOTE: The free board distance is the most important variable and should be maintained. Sand density will vary
and therefore sand amount is given as a reference.
† Media required to meet NSF requirements.
‡ Pea Gravel to be 1/4” to 1/8” diameter.
* Sand to be No. 20 standard silica (uniformity coefficient not greater than 1.75) .018-.020 in diameter particle size.
