Upon initial start, onepump will initially come on for 5 minutes and then cycle through each pump sequentially for a one minute duration.
Priming Pumps
1.Turn off power at electrical service panel.
2.Locate and loosen the pump union by turning it counterclockwise one half of one turn.
3.Allow air to escape from the fitting. When a steady stream of water flowsfrom the pump union, close it by turning it clockwise until tight.
4.Turn on power at electrical service panel.
5.Perform one additional check to ensurewater is flowing from the jets during the auto purgecycle. If so, continueto Water Preparation. If no water flow is coming from the spa jets, please call your Island Spas™dealer for further assistance.
