Period Check Point Related Problems
Weekly Check pressure gauge
If pressure increases by 8-10 PSI, then backwash and rinse the lter as per
instructions
Quarterly
Check all gaskets and pressure
gauge.
Isolate and turn o the pump. Remove all gaskets and turn over. You can also
apply a silicone-based grease to extend gasket life. If dry, then contact your
local pool professional for replacement
Check around the unit for leaves,
debris or signs of ooding.
Replace any debris that is restricting air circulation around the lter. If in a
ood prone location, rectify
Check for any insects, ants, etc.
It is a good practice to use a good quality surface spray around your
equipment. Make sure all units are turned o and then spray around all units
to eliminate any insects, ants, etc
Check for any leaks
If you notice any water leaking from the lter or other equipment, check the
gaskets rst and reseal. If leaks continue, contact your local pool professional
to assess and rectify

3. Power up the pump again. The water flow is
automatically reversed through the filter so the water
is directed from the bottom of the tank, then up
through the sand. This flushes the trapped dirt and
debris out of the waste line.
4. Check through the visual sight glass on the multi-
function valve outlet. The duration of the backwash
operation will depend on how dirty your filter is.
Continuously check the sight glass until the water
becomes clear, after which the pump is turned off.
5. Change the position of the multiport valve handle
from BACKWASH to RINSE.
6. Turn the pump back on. The water flow will now be
directed through the sand bed and then out through
the waste line. This will settle the sand bed properly
for normal operation.
7. Continue checking the sight glass until the water
is clear which usually is about half the time of the
backwash cycle.
8. Turn the pump off.
9. Change the position of the multiport valve handle
from RINSE to FILTER.
10. Turn the pump on.
Chemical Cleaning
Algae load, calcication, sanitation and other poor water
conditions will aect the proper function and eciency
of the lter. Follow local guidelines and pool professional
advice to optimize these other key facets of water quality
that the lter does not control, but is impacted by.
Winterizing the System
AA
CAUTION: Allowing water to freeze in the system will
damage the system and cause potential water damage/
ooding and potential property damage.
AA
CAUTION: The Multiport Valve should be left in the
"Winterize" position during the shutdown season so
the rubber seal of the valve diverter has no pressure on
it. Failure to do so can damage the valve diverter seal
which can cause property damage from leaking water.
CAUTION: Only use Propylene Glycol as an anti-freeze,
as other anti-freeze solutions are highly toxic and will
damage the pump.
Winterizing is a process for protecting your sand lter
during freezing conditions that can damage all pool
ltration equipment. Damage results from ice expansion
(ice takes up more volume than liquid water) cracking the
parts. It is highly recommended to take the following steps
when preparing your lter for winter conditions:
1. Backwash the filter for at least 30 minutes before
closing down the pool for winter. This will clean the
filter bed thoroughly and remove any debris from the
system.
2. Drain the filter tank by removing the drain cap at the
bottom of the filter tank. Also leave the cap off during
winter.
3. Set the control valve handle between the RINSE and
FILTER. This will lift the handle and help with the
draining process by allowing air to enter into the tank.
4. Unscrew the pressure gauge from the control valve
and store the pressure gauge indoors.
5. Drain and winterize the pump according to the pump
instructions.
This is an ideal time for any repairs that may be required
during the o-season. Most pool professionals have
recommendations of what will be needed before the next
pool season.
