Water Maintenance

• Keep water level at least 50mm (2") above bottom of skimmer opening. Failure to do so can allow air to enter system, causing
pump to lose prime and air to enter filter.
• Maintain pH at 7.2 to 7.6 in pool.
Vacuum Pool
1. Fill vacuum hose by submerging in water from one end to the other.
2. To vacuum, insert hose into skimmer suction manifold or into vacuum line in pool wall. See instructions provided by pool
builder or pool manufacturer. Start pump, making sure it is primed and pumping.
3. After vacuuming, clean pump trap to remove accumulated debris, then check filter pressure gage. If reading is 0,3 to 0,5 Bar (5
to 7 PSI) higher than initial operating pressure, backwash filter.
Lower or Drain Pool
1. Turn pump 'OFF'; set valve handle to 'WASTE'.
2. Use vacuum cleaner hose and head.
3. Start pump; run until pool is lowered to desired level.
4. Turn pump 'OFF'; set valve handle to 'FILTER'.
5. Start pump.

Storage/Winterizing

Pool chemicals may give off corrosive fumes. Store chemicals away from system in a well
ventilated area.
NOTICE: Allowing water to freeze will damage filter and void warranty. If antifreeze is needed, use propylene
glycol; it's plastic compatible and non-toxic. Follow manufacturers instructions. Do not use ethylene
glycol based anti-freeze – it's toxic and it may damage plastic components.
1. Open all system valves. Set multiport valve at 'WINTERIZE' to allow air passage to all ports.
2. Remove drain plug from filter and drain filter tank completely and replace drain cap.
3. Cover filter to protect from freezing weather, but do not seal from air circulation.
Startup for Winterized Equipment
1. Remove any temporary weather protection placed around system for shutdown.
2. See "Startup" for reactivation of the filter.
3. Inspect all electrical wiring to pump for damage or deterioration over the shutdown period. Have a qualified serviceman repair/re-
place wiring as needed. Inspect and tighten all watertight connections.
4. Open all valves in suction and return piping.
5. Remove any winterizing plugs in system.
6. Drain all winterizing chemicals (if used) from system; flush system.
7. Close all drain valves and replace all drain plugs in system.
8. Fill pool with water to proper level (see pool manufacturer's instructions).

Troubleshooting Guide
1. Short Cycle between backwashes:
A. Flow rate too high or filter 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 filter; consult dealer for chemical filter 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 "Startup/Operation" section.
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 filter sand for solidification caused by dust, calcium, skin oils, or suntan lotions.
Hazardous pressure.
Can cause severe injury or major
property damage from tank blow up.
Release all pressure and read instruc-
tions before working on filter.
2. Low Flow:
A. Pipe blocked downstream from filter; remove obstruction.
B. Piping too small; use larger pipe.
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. Follow procedure
under "Filter Setup" section, and instructions with new lateral to replace broken part.
