Basic Tips
for Preventive Maintenance
|
- Preventive
maintenance is much more cost effective than corrective maintenance.
It considerably reduces the building life-cycle costs, energy
bills, repairs, and corrective maintenance & equipment replacement.
- Basic principle
of preventive maintenance is to Fix minor problems before they
result in major repairs. For this regular inspection of all equipment
by trained staff is necessary. Maintain regular operation & maintenance
log for major equipment.
- During a
maintenance shutdown wiring, contacts & other components should
be thoroughly inspected for voltage imbalance, loose connections
or self heating.
- Adjust schedules
to keep all equipment on only when necessary. Adjust temperature
& humidity set points for AC within comfort zones seasonally.
- If major
repairs are required, evaluate the economic benefit of replacing
the old equipment with more efficient and compact equipment before
doing the repairs. Such study should be done well in advance,
so that in case of breakdown a decision can be taken quickly.
- Thermostats
for air-conditioning control should be calibrated after regular
interval & replace inaccurate gauges & thermometers. Use night
setback temperature during unoccupied hours.
- To implement
an effective preventive maintenance program, the operational staff
must be given comprehensive training on each type of equipment,
regarding system fundamentals, use of reference material & manuals,
maintenance procedures, service guidelines & warranty information.
3. Proper maintenance schedules could be supplied to them for
different equipment.
