Pre-Installation Checklist
1. All Ports (drains, skimmers, vacuum lines, etc.) MUST BE FREE OF
DEBRIS PRIOR TO INSTALLATION. Clogged ports will disrupt the
normal vacuum level.
2. Backwash or otherwise clean filter as per manufacturer specification.
3. Clean pump trap basket and skimmer basket(s).
4. Inspect main drain cover. (Also Inspect Spa Drain if present) Drain covers
must be free of obstruction, securely fastened w/ stainless steel screws, and in
sound condition w/ no cracks or breaks.
5. Repair any leaks in circulation system before installation. Leaks will cause
the formation of air bubbles that disrupt the normal vacuum level.
6. Set all valves to normal operating position. Vacuum port valve(s) should be
closed and dedicated vacuum line(s) should be capped in pool. Installations
with pool and spa combinations, with a single pump, we recommend you
consult your pool builder or service professional about closing the spa drain
line during regular filtration.
7. Pump should be run prior to installation and left in fully primed condition.
8. ALL CHECK VALVES MUST BE REMOVED FROM SYSTEM!
Check values can cause a dangerous vacuum condition to remain even after
pump shut off.
