NuAire CYFAN-C Installation And Maintenance Manual

SECTION 1.0
INTRODUCTION
CYFAN-C EXTRACT FANS
The Nuaire CYFAN-C centrifugal extract fan is a major advance-
ment and has been designed to meet the flow rates for all wet
room applications such as the bathroom, kitchen, utility and WC
etc.
The unit discharges air through a 100mm or 125mm dia. spigot which
for surface and semi-recessed mounted units exits at the rear of the
unit. The subsidiary spigot kit allows the fan to extract air through the
side of the fan via a 50mm dia. spigot.
The motor is 24V brushless DC. Bearings are sealed, self-lubricating
ball type with integral locked rotor protection.
Units are supplied with a separate transformer enclosure if fans are
required for SELV usage.

Warning: Isolate from power supply before removing any covers.
During installation/maintenance ensure all covers are fitted
before switching on the mains supply.
