Maintenance Procedures
Maintenance Strategy
The primary goal of preventive maintenance is to avoid the
consequences of equipment failure. Trane chillers are
designed for ease of access with a premium placed on
locating key components to facilitate visual inspection and
hands-on verification. One approach to chiller maintenance
envisions three levels of maintenance effort reflecting
frequent, periodic, and scheduled maintenance tasks, with
each level building on the previous level. See below figure.
•
A daily or weekly "health check" involves habitual visual
and manual inspections of the components of the
chiller so that anomalies become evident when they
occur.

Federal Clean Air Act
Responsible refrigerant practices are important to the
environment, our customers, and the air conditioning
industry. All technicians who handle refrigerants must be
properly certified. The Federal Clean Air Act prescribes
procedures for handling, reclaiming, recovering, and
recycling of refrigerants and the equipment that must be
used in maintenance procedures involving potential
leakage of HVAC refrigerants. State and local governments
may have additional requirements that must be followed to
responsibly handle HVAC refrigerants.

•
Weekly or monthly periodic maintenance involves
cleaning specific components and inspecting glycol and
lubrication fluids.
•
Prudent maintenance strategy will anticipate and
schedule replacement or rebuilding of critical
components before they fail and require emergency
response to keep chillers operational.
Maintenance for HVAC equipment and facilities can include
a "preventive maintenance checklist" which includes small
checks which can significantly extend service life. Other
considerations such as weather and equipment age are
taken into account; maintenance and equipment
replacement is often performed before the hottest time of
the year.
Inspection and Maintenance
Schedule
Proactive measures should be taken to prevent potential
problems with the heat pumps. These include maintaining
a operational log and conducting weekly, quarterly, and
annual inspections of the heat pump. See following table.
Daily
A daily visual inspection can reveal obvious problems.
Keep notes of the heat pump performance:
•
Log pressures and temperatures.
•
Visually inspect of the unit.
