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.
Table B. Maintenance Service Schedule
7. Note the initial pressure gauge reading when the filter
is clean. It will vary from pool to pool depending upon
the pump and general piping system. Over time, as
the filter removes dirt and impurities from the pool
water, the accumulation of dirt in the filter will cause
the pressure to rise and diminish the water flow.
When the pressure gauge reading is 8-10 PSI higher
than the initial "clean" pressure you noted, it is time to
backwash the filter (see BACKWASH under filter and
control valve functions).
7. GENERAL MAINTENANCE
NOTE: It is essential to set up a regular schedule to
clean the sand lter by BACKWASHING and RINSING to
provide clean, safe and healthy swimming water. The
time between cleaning and the length of cleaning time
will depend on size of pool, bather usage and other
environmental conditions. Consult your local pool
professional to work out a program that best suits your
pool.
Pump
A
WARNING: To prevent damage to the pump and for
proper operation of the system, clean the pump strainer
and skimmer baskets regularly.
The only routine maintenance needed is inspection and
cleaning of the trap basket (pre-lter basket). Debris or
trash that collects in the basket will reduce or stop water
ow through the pump. Follow the instructions below to
clean the trap.
1. Stop the pump, close the suction and discharge gate
valves, and release all pressure from system before
proceeding.
2. Unscrew the trap lid (pre-filter lid) by turning it
counterclockwise.
3. Remove the strainer basket and clean it. Be sure all
holes in basket are unobstructed. Flush the basket
with water and put it back in the trap (pre-filter) with
the large opening facing the pipe connection port. If
the basket is put in backwards, the cover will not fit
on the trap body.
4. Clean and inspect the lid.
5. Clean the O-ring and its groove on the trap body
(pre-filter) and replace the lid. To help keep the lid
from sticking, tighten by hand only.
6. Prime the pump (see priming instructions above).
Filter
It is important to maintain a regular service schedule
program with pool equipment to ensure the best operation
and the longest lasting results. Regular maintenance can
identify any potential issues early and save on expensive
maintenance at a later date, see Table B.
Filter and Control Valve Functions
Information is provided in Figure 3 and Table C for using
the control valve to regulate all the lter functions.
General
A boss with pipe tap is provided for installing the optional
inuent pressure gauge.
Valve Service
Stop the pump, close the suction and the discharge gate
valve before proceeding:
1. Set the handle in filter position.
2. Remove the cover screws.
3. Lift the cover and key assembly out.
