Maintenance record: The following pages have been designed to be printed, completed and stored
as a maintenance record for standard systems.
Any damage that is identified as part of an inspection should immediately be
reported to Kelvin Hughes and appropriate action taken to prevent further
damage occurring.
Procedure: Prior to carrying out any maintenance the system must be fully isolated from
all sources of AC power including any UPS supported supplies, the required
maintenance task(s) should be undertaken and on completion, the power
restored and the system fully tested.
Spares: Where required, only Kelvin Hughes approved spares must be used. The use
of unapproved spares invalidates the warranty status of the unit could lead to
a malfunction of the system.
Adverse weather: It is strongly recommended that the gearbox inspections noted in Annual
Maintenance procedures are carried out at the earliest safe opportunity after
the system has been exposed to severe or adverse weather conditions.
Health & safety: All safety warnings for the system noted in section 2 must be observed at all
times when working on, inspecting or maintaining any part of the system or
its associated sub systems.
