19. Maintenance Procedures
This section describes the procedure that must be performed as a part of normal maintenance program. Regular servicing
of equipment by licensed technician is highly recommended. Regular servicing of your unit helps in maintaining its optimum
performance and reliability.
The checklist and service periods provided on this manual are guides only, as some sites
may require more frequent servicing.
Always disconnect electrical power to the unit before performing maintenance. It is always a safe practice to observe all
safety warnings and cautions when conducting maintenance tasks.
DANGER
Live Electrical Connections !
It may be necessary to work with live electrical components on certain maintenance tasks. Only qualified technicians are
allowed to perform these tasks.
WARNING
Hazardous Voltage !
Always make sure that all power supply, including remote controls, are disconnected before performing maintenance. Observe
proper LOCK-OUT / TAG-OUT procedures to ensure that power cannot be inadvertently energised. Failure to disconnect
power before maintenance procedures can result in serious injury and/or death.
Annual Maintenance Checklists
• Perform general maintenance inspections.
• Perform scheduled start-up checks.
• Leak test refrigerant circuits.
• Inspect contacts of all contactors and relays. Replace all worn contacts as required.
• Inspect, clean and tighten all electrical connections.
• Check fans for balanced operation. Make sure that there are no loose screws / bolts, no fan blades interference
and no damage to the fans and guards.
• Inspect the air filters, clean or replace as required.
• Clean and repaint any corroded panel section.
• Ensure no blockage of airflow through variable speed drive and drive fan is operating correctly.
Cleaning the Condenser Coils
Clean the coils at least once a year or more frequently if the unit is located in a dusty and dirty environment, in order to
maintain your system’s proper operating performance. High discharge pressures are good indication that the coils need
cleaning. When using detergent or solvents to clean the coils, follow the manufacturer’s instructions to avoid potential
damage to the coils and to the unit.
To clean the refrigerant coils, use a soft brush and water spray, such as garden hose or pressure washer with low pressure
nozzle.
CAUTION
Do Not Use High Alkaline Detergent !
When using detergent for coil cleaning, ensure that the alkaline level is no higher than 8.5, which can cause corrosion damage
to the coils.
