Piping
When arranging the piping connections to the Blower, observe the following,
1. 50 mm (2") Class 9 or higher PVC pipe should be used in the installation. Using smaller
diameter pipe will place stress on the motor.
2. Do not glue piping to the Blower.
3. Avoid water traps when installing the piping as they will reduce the efficiency of the Blower
(refer to Figure 5d on Page 8).
4. Install pipe loops where necessary (refer to Figure 5c on Page 6).
5. Horizontal pipes shall have a one (1) degree fall towards the Spa.
6. Check Valves shall be installed when the Blower is used in a Spa Jet Installation (refer to
Figure 5a on Page 6).
7. Keep the number of 90 degree elbows to a minimum. Where possible, use two (2) 45 degree
elbows instead of a 90 degree elbow.
8. Keep the length of piping between the Spa and the Blower as short as possible (length of
piping should not exceed 12 metres).
!
CAUTION
Care must be taken to ensure loose material or water (including rain) will not be sucked into the
piping connected to the Inlet Port of the Inline Blower. Failure to do so may result in serious damage.
