Replacement of sand
Open the drain and let the water ow out. Remove the sand. This can be done by means of the vacuum system “Sandvak”, which can
be connected to the main water supply just like a garden hose. The lter can also be emptied by hand.
Triton® : To replace the sand, turn the top diffuser system to the side. The thread of the lter should be protected, in the same way
as with lling.
Take care not to damage the bottom laterals.
The sand in the lter must be changed every 5 years.
Do NOT clean or spray the lter dome with lubricant that contain alcohol!
Winterizing
In areas that have freezing winter temperatures protect pool equipment. The lter, pump and pipelines must be emptied to protect
them from freezing. To do this move the valve handle to the “Backwash” position, open drain tap with hose connection end 180° to
the left (do not unscrew) and open the bleed valve. Open all valves. A small exible piece of tubing can be attached to the drain tap.
Allow lter, pump and pipelines to drain completely
Section 7
Trouble shooting
1. Short Cycle between backwashes
A. Flow rate too high or lter too small: consult dealer for system sizing recommendations.
B. Water is chemically out of balance: consult pool serviceman.
C. Excess dirt/dust in pool: vacuum pool directly to waste.
D. Body oil/lotion build-up in lter: consult dealer for chemical lter cleaners and follow cleaner
manufacturer’s instructions.
NOTICE: Time between backwashes will vary with each installation and between different areas of the country. Ask installer about
normal backwash interval in your area. The following causes and remedies are for cycle times shorter than normal for your
area.
E. Filter inadequately backwashed: see instructions under section 5.
F. Algae in pool: consult pool professional about proper chemical maintenance.
G. Residual chlorine level too low: consult pool professional about proper chemical maintenance.
H. Inspect lter sand for solidication caused by dust, calcium, skin oils, of suntan lotions.
2. Low Flow
A. Pipe blocked downstream from lter: remove obstruction.
B. Piping too small: use larger pipe (consult dealer for sizing).
C. Plugged pump; plugged hair and lint trap or skimmer basket. Clean thoroughly.
3. Pool Water Not Clear
A. Water is chemically out of balance: consult pool professional.
B. Filter is too small: consult dealer about equipment sizing.
C. Sand in pool means broken lateral. Drain both water and sand out of tank. Remove valve and replace broken
part. Reassemble lter.
