The Hydro System can be identified by the jets which are located in the walls of the spa bath. When the system is activated, water is drawn from the bath via the suction outlet by the pump and recirculated through the jets in a continuous cycle.

Most spa bath jets are fully adjustable. The strength of the massage can be controlled by turning the jetface clockwise or counter clockwise until the desired effect is achieved. The direction of the water flow can be altered by adjusting the multi directional eyeball.

Air can be introduced into the water flow by opening the venturi controls which are located on the flange of the bath. Spa baths with 6 or 7 jets should be supplied with two venturi controls allowing individual control of the air to the jets, greater aeration and a stronger massage.

IMPORTANT- spa bath pumps should never be operated without the spa bath being filled with water to a minimum of 30 mm above the level of the spa jets.

The Air Massage System

The Air Massage System can be recognised by the small injectors which are located in the base of the spa bath.

Air is pushed through the injectors by a 3 speed heated blower module and the resultant massage effect has been described as a "champagne massage" because of the volume of bubbles which are created.

The injectors are self sealing when not in operation and the blower unit has an inbuilt purging cycle which will activate 10 to 15 minutes after the system has been turned off. The blower will run for a further 30 seconds to clear any water retained in the line.

It is recommended that the blower be mounted a minimum of 600 mm above the level of the bath and preferably in ceiling space. However, should the blower be mounted externally, it must be protected from the weather and provided with adequate ventilation.

The Dual System is a combination of the hydro system and the air massage system.
