ROUTINE (PREVENTIVE)
MAINTENANCE
The equipment is designed to keep levels of maintenance to an absolute
minimum.
Cleaning Windows It is important that the optical windows of both transmitter and receiver are
kept reasonably clean and any mounting tubes free from build-up of dust and
fly ash. We recommend that the windows are cleaned every six months, or
more often for dirty processes, by removing the transmitter and receiver from
their air purges and wiping their windows with a soft dry cloth.
Replacement of the
Heater Element
The heater element does have a limited life and at some stage will have to be
replaced. The unit has been designed to give a minimum of two years
continuous operation and when replacement does become necessary it can
be replaced on site.
Install all protective equipment covers and safety ground leads after equipment repair or
service. Failure to install covers and ground leads could result in serious injury or death.
Great care must be taken when removing the CCO 5500 from a positive pressure stack or
duct. The source may be very hot, and there may be dangerous vapors present. Observe all
required safety practices.
