Module Cleaning Procedure - STA-RITE S7MD60 Owner's Manual

Hazardous pressure.
Can cause severe
injury or major
property damage
from tank blow up.
Release all pressure
and read instructions
before working on filter.
When to Clean the Filter
The filter module should normally be
cleaned when the pressure gauge read-
ing increases 10 PSI over the start-up
pressure (record the start-up pressure in
a convenient place).
In some pools, accessories such as
fountains or pool cleaners may be no-
ticeably affected by the normal decrease
in flow as the filter becomes dirty. If so,
clean the filter more frequently (that is, at
a pressure increase of less than 10 PSI)
in order to maintain the required flow.

professionals for pool
industry recommended
filter cleaners.
MODULE CLEANING
PROCEDURE
Risk of chemical burns. Do not attempt to acid clean the filter or
module. If the filter requires acid cleaning, have a trained pool professional
do the job.
Follow all steps in the "Disassembly" section of this manual.
The filter module should be removed and cleaned when pressure rises more
than 10 psi (69 kPa) above startup pressure. See also "When to Clean the
Filter," at left.
NOTICE: Do not expose the filter module to sunlight for any extended period
of time.
NOTICE: When sanitizing your pool using PHMB (polyhexamethylene bi-
quanide based) cleaners, use only PHMB cleaners to clean the module.
When using PHMB sanitizers, the filter module MUST be cleaned more thor-
oughly and frequently than for a pool using chlorine. Follow manufacturer's
instructions carefully. Use of any other type of cleansers with PHMB pool
sanitizers will void the filter's warranty.
NOTICE: Avoid washing filter debris into the outlet port. Remove drain plug
and flush dirt from inside of tank before removing filter module.
1. With a hose equipped with a soft flow nozzle, wash as much dirt as pos-
sible off of the filter module while it is still inside the tank. Allow tank to
drain completely.
2. Make sure that the inside of the tank is clean. Lift out the module and
hose it down thoroughly. Spray the entire module surface. Allow module
to drain.
3. Inspect the module. If necessary, repeat the washing operation. If the
module is damaged, replace it.
NOTICE: If this cleaning method does not remove all deposits, see
"Special Cleaning Instructions" section in this manual.
4. Inspect and clean air bleed filter at top of module.
5. Follow all steps in the "Assembly" and "Initial Startup" sections of this
manual.
