Installation Manual
11.9 Electric Heaters
An air handling unit would normally require no heater maintenance.
However a periodic check is advised to ensure that the fasteners and
electrical connections are operating correctly.
The electric heater unit is fitted with fail-safe thermal switches (self-
resetting) which will isolate the electric heater supply if a temperature
of 80°C is detected. This action is performed independently of any
controls fitted. Nuaire fitted controls will also stop heating if a fan or
heater failure is detected.
11.10 Bulkhead Lights
Ensure that lights are switched off and isolated before checking or
changing the lamp.
11.11 General
Inspect all internal and external surfaces to check for corrosion or
peeling of painted surfaces.
Thoroughly clean affected areas with a wire brush, apply a coat of zinc
rich primer or similar, and re-touch with suitable finishing paint. Ensure
tightness of all nuts, bolts, and fixings.
Check all components for general condition.
11.12 Specialist Equipment

would have been specified during design stage. A breakdown of the
component parts can be found on the design specification documents,
