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 filtration as well as proper water chemistry. Pool chemistry is a
specialized area and you should consult your local pool service specialist for specific 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 filter
components are damaged, notify the freight carrier immediately.
2. Carefully remove the accessory package and the filter tank from the carton.
3. Mount the filter 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 filter 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 filter. One needs to be able to stand clear of the filter when starting the pump. Minimum space
requirements may be found on the large nameplate on the filter.
5. Position filter so that the port locations are in the desired final 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
fittings 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 fittings. It is not
necessary to cinch the valve nuts to the tank fitting 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 filter.
9. Sand specifications – be certain the proper sand is used as described in Table 2. Before pouring
the sand into the filter, look inside and check the lower under-drain for broken or loose laterals (or
fingers), 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.
