Monthly Filter Cleaning Procedure
We recommend cleaning the outer pleated filter (1) with a high pressure water nozzle and the
filter insert (2) with a low-pressure water nozzle monthly. Periodically, the outer pleated filter
cartridge (1) will require a more thorough cleaning to remove embedded oils and minerals by
using special spa filter cleaners offered by your spa dealer. Always remove the center filter
insert (2) before cleaning the outer filter (1) with chemicals. Never use filter cleaners of
any kind on the filter insert (2) or it may be damaged.
Procedure:
1. Grasp center filter insert end cap (2) in hand and pull
outward from pleated cartridge (1). If filter insert (2) is
6 months old, throw it away and purchase new one.
DO NOT install new insert at this time.
2. Rinse debris from all outer filter (1) pleats using a
garden hose and high-pressure nozzle. Repeat
process until all filter pleats are clean. Then rinse
debris from inside of filter (1). If chemical cleaners
are used, follow manufacturers instructions.
Lightly rise filter insert (2) and place in clean location. *DO NOT use chemical cleaners or high-
pressure nozzle on insert (2) or it may be damaged!
3. Install filter insert (2) into outer pleated filter
(1) by gently sliding inward until a slight resistance
is felt approximately 1/4” from bottom. Lightly tap insert end with palm of hand to “snap” in place.
Insert is properly installed when end cap rests “flush” against outer filter end cap.
4. Install Filter assembly back into spa by performing step 2 in reverse order. Tighten filter nut so it
just touches the filter face. DO NOT OVERTIGHTEN!
5. Turn power to spa back on.
TURN POWER TO SPA OFF! NEVER OPERATE SPA WHEN FILTER IS
NOT PROPERLY INSTALLED OR IF WEIR ASSEMBLY IS DAMAGED
OR ALTERED!
Replacement lter cartridges may be purchased from your Sundance
Spas dealer.
