To Connect Piping to the Blower
1. Unscrew the small securing screw from the Outlet Port.
2. Smear some silicon sealant around the inside surface of the Outlet Port.
3. Insert the pipe into the Outlet Port and tighten the securing screw.
Above Water Level Installation
(Refer to Figure 5 a & b on Page 5)
The bottom of the Blower should be at least 700mm above the water level of the spa to prevent
water from entering the blower.
Below Water Level Installation
(Refer to Figure 5c on Page 5)
The connecting piping must have a vertical loop where the top of the loop is at least 700mm above
the water level of the Spa. The loop should be as close to the Spa as possible and must have a
1.0mm hole in the top of the loop to allow gas to escape. A 1.0mm hole is also required as a drain
hole to prevent any water from entering the Blower.
Spa Jet Booster Installation (Additional Requirements)
(Refer to Figure 5a on Page 5)
If using the Blower in a Spa Jet Booster application, take the following steps,
Install a Check Valve in-line with the Blower. This is a one-way valve that will ensure no water enters
the Blower.
Ensure there is a 3.0mm drain hole between the Check Valve and the Blower.
For maximum efficiency of the Blower, keep the number of jets between 6 and 8.
Air Manifold Installation (Additional Requirements)
(Refer to Figure 5b on Page 5)
This style of installation requires a suitable number of holes to be present in the seat of the spa for
the blower to work efficiently.
Minimum number of holes with 6mm diameter : 36
Minimum number of holes with 9mm diameter : 18
