3. Add sand (not provided) following recommendation for size and
amount. Be sure that standpipe remains centered while pouring sand.
Be sure sand is level.
4. Remove cover from standpipe.
DIAL VALVE INSTALLATION
Carefully remove all sand particles from the mounting location. Position
the rubber O-ring on the dial valve body. Place valve on tank and rotate
until the valve inlet is approximately in line with the pump outlet open-
ing. Install the V-clamp. Install pressure gauge after wrapping threads
with teflon tape.
DIAL VALVE FUNCTIONS
FILTER
- For normal filtering. This position also can be used for regular
vacuuming.
BACKWASHING
- Clean your filter with this position. Note instructions
on Cleaning Filter.
DRAIN
- This position allows you to pump water from the pool - the flow
from the pump is permitted to bypass filter and go directly to the waste.
Use this position to vacuum heavy concentration of debris.
WHIRLPOOL
- By bypassing the filter, this position creates more pres-
sure to obtain optimum performance from any hydro-therapy fittings.
No filtration occurs while the valve is in this position.
WINTERIZE
- This is a neutral position which is used only when pump
is stopped. It allows air to leave - or enter the tank to help priming and
draining.
RINSE
- (6 and 7 position dial valve only, not available on 4 position
dial valve.) For sitting filter bed after backwashing and for carrying
any remaining loose dirt to waste. The rinse prevents any return of re-
sidual dirt to the pool that occurs momentarily when changing directly
from BACKWASH TO FILTER.
TEST
- (6 and 7 position dial valve only, not available on 4 position dial
valve). This position prevents any backflow of water from pool during
pump maintenance if filter is below water level.
FILTER START-UP
1. Set dial valve to DRAIN position.
2. Perform pump start-up.
3. After good flow has been established, continue pumping for one minute
or until wastewater is clear.
4. Stop the pump. Set dial valve to BACKWASH and restart pump.
5. Observe the waste water. When flow becomes clear (approximately
2 to 3 minutes). STOP pump.

6. If your dial valve does not have a RINSE cycle, proceed to STEP 7. If
your dial valve does have a RINSE cycle, set it to that position, restart
pump and allow it to run 20 seconds. STOP pump.
7. Set dial valve to FILTER and restart pump.
WATER CHEMISTRY
Proper and consistent use of chemicals is necessary to maintain clean,
sanitary water, prevent a spread of germ infection and control the growth
of algae which can spoil the appearance and enjoyment of your pools or
spa.
Chlorine is the most commonly used chemical to provide clean, sani-
tary water. Either dry or liquid chlorine can be used which should be
added daily as it is dissipated by dirt and germs as well as by the sun
and the wind.
It is also important that the correct level of acidity or alkalinity of the pool
water be maintained. This is the pH of your pool with pH 7.0 being neu-
tral. Readings above pH 7.0 are alkaline and readings below are acid. A
desirable range is 7.2 to 7.4. Consult your local pool/spa dealer for com-
plete information on the proper application and use of chemicals.
FILTER MAINTENANCE
Filter tank and contents should not require attention other then
backwashing provided water is kept in continuous chemical balance
without heavy dosages
of corrosive chemicals.
CLEANING FILTER (Backwashing)
When the new filter is placed in service, note the reading on pressure
gauge. As dirt builds up in filter, the pressure reading will increase. When
it reads 6-8 PSI above the original reading, it is time to Backwash as
described below.
1. STOP pump.
2. Set dial valve to BACKWASH and start pump.
3. Observe the waste water. STOP pump when flow becomes clear
(approximately two to three minutes).
4. If your dial valve does not have a RINSE cycle proceed to step 5. If
your dial valve does have a RINSE cycle, set it to that position, restart
pump and allow to run 20 seconds. STOP pump.
5. Set dial to FILTER and start pump to resume filtering operation.
Do not use pool vacuum cleaner when filter is backwashing.
WINTERIZING
Consult your dealer for advice on wintering your equipment if freezing
temperatures occur in your locality. Their knowledge of your equipment
makes them the best qualified source of information. Follow their rec-
ommendations, and if these include draining the filter system, proceed
as follows:
1. BACKWASH for 3 to 5 minutes and the set dial valve to WINTERIZE
position.
2. Drain system by removing drain plugs and/or removing pipe caps
from the filter, pumps, and disinfecting equipment. Store plugs in a dry
place for safekeeping.
