MAINTENANCE PLAN
Rooftops are generally placed on the roof but can also be installed in technical rooms. These units are very robust but minimum
regular maintenance is required. Some moving parts in the units can suffer from wear and tear and must be checked regularly
(belts). Other parts can get clogged by dirt carried in the air (filters) and must be cleaned or replaced.
These units are designed to produce cooled or heated air through the use of a refrigeration vapor compression system, it is
therefore imperative to monitor the refrigeration circuit operating pressures and check the pipe-work for leaks.
The table below, details a possible maintenance plan, including the operations to be carried out and the periodicity at which
they must be accomplished. It is recommended to follow such a plan to keep a rooftop unit in good working order. Regular
maintenance of your rooftop will extend its operating life and reduce operating faults
Symbols and Legend:
•
Operation which can be carried out by on-site maintenance technicians.

Operation which must be carried out by qualified refrigeration personnel, trained to operate on this type
of equipment
NOTE:
•
Times are given for information purpose only and may vary depending on the unit size and type of installation.
•
Coil cleaning must be carried out by qualified personnel using appropriate methods that won’t damage the fins or the tubes.
•
It is recommended to keep a minimum stock of common replacement parts in order to be able to carry out regular
maintenance operations (i.e. filters). You can contact your local Lennox representative which can assist you in establishing
a parts list for each type of equipment.
•
The access ports to the refrigeration circuits MUST be leak checked every time gauges are connected to the service ports
