WATERCO SPA BLOWER
The following instructions cover all models of Waterco Spa Pool Blowers (Airflo and the Whisperair
line). While much of this manual applies to all blowers, please identify your model and follow any
specific instructions that relate to it.
Waterco Blowers are designed for use in either Spa Jet Booster or Air Manifold applications where,
in both cases, air is forced through the connecting piping and into the Spa. They are suitable for
both above and below water level installations provided the guidelines set out in this manual are
followed.
Waterco Blowers have an integrated Thermal Cutout that will switch off the electric motor if it
overheats. If the Thermal Cutout is tripped, the motor will automatically restart once it has sufficiently
cooled down.
Waterco Blowers are designed to meet the specifications set out in AS/NZS 3136.
MODELS
Standard Model – Airflo, Whisperair, Whisperair S
The standard model of the Blower draws air into the unit through the Bottom Cowl of the Blower.
The Airflo version has plainly visible Air Inlet holes throughout the Bottom Cowl, while the Whisperair
models draw all the required air in through gaps around the perimeter of the Bottom Cowl.
Inline Model – Whisperair Elite, Whisperair S Elite
The Inline version of the Blower differs from the Standard Model in that rather than having Air Inlet
holes in the Bottom Cowl of the casing, it has an Inlet Port in the top of the Outer Housing. The
piping connected to this port should then be extended to a safe and convenient position. This
makes the Inline Model quieter than the Standard Model when running.
