All comply with the requirements of AS/NZS3350.2.60
1)
The Millenium blower has passed all electrical and environmental
regulations -EMC. AS3136/NZS6232 and relevant provisions of
AS/NZS3100.
2)
The Millenium blower must be installed in an enclosure rated at IPX5
(AUS8NZ)
In all cases refer to your national wiring rules or codes of electrical prac-
tice. In order to prevent a hazard, if the supply cable is damaged or the
unit is not working it must be returned to the manufacturer or an authorised
service agent for repair. This is a Class 1 appliance and must be connect-
ed to the permanent wiring. The appliance should be supplied through a
residual current device (RCD) with a rated tripping current not exceeding
30mA. This appliance must have a switch or other means of all pole
disconnection from the supply, having a contact separation of at least 3
mm, and must be incorporated in the fixed wiring to the appliance.
Refer to AS/NZ5 3000 : 2000 and IEC 60364 Part7 (Europe) for guidance with
compliance to the wiring codes for wet area and equipotential bonding.
IN GROUND SPA INSTALLATION
1.
The blower must be in a dry area as close as practical to the spa. In
installations more than 4 meters from the pool, the safety loop should
be close to the spa.
2.
Safety loops and risers - to avoid water damage to the blower, the
blower should be installed at least 700mm above the water level in
the spa (fig. 1) or be protected by a safety loop (Fig 2). Water dam
age is not covered by warranty.
3.
All piping should be in 40mm PVC pressure pipe.
4.
The minimum ventilation (free space around the blower) should be
50sq.cm in accordance with AS/NZS2023:1995.
PORTABLE SPA INSTALLATION
1.
Portable spas require a double safety loop plus a check valve (as in
Fig 3) or a vent valve (as in fig 4).
2.
A 3mm hole a point (A) is recommended to allow accumulated
condensation to drain out.
3.
All piping should be in 40mm PVC pressure pipe.
4.
After wet testing the spa, the blower should be disconnected for the
safety loop to stop residual water getting into the blower during transit.
