MAINTENANCE
Maintenance Procedures
This section describes the specific maintenance procedures that must be performed as a part of
normal maintenance program. Always disconnect electrical power to the unit before performing these
procedures. It is always a safe practice to observe all safety warnings and cautions when conducting
maintenance tasks.
Periodic Maintenance Checkpoint
• Perform all monthly maintenance inspections
• Inspect coil surfaces for cleanliness. Clean as
required, apply cleaning procedures based on
prevailing industry standard.
•
Inspect unit air filters, clean or replace as
required.
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 unit air filters, clean or replace as
required.
• Clean and repaint any corroded panel surface.
Cleaning the Control Interface
Wipe the control interface with dry cloth. Do not
use water or any other solvent based solutions
as it can cause damage to the outer case and
electronic components of the controller.
Air Filter Maintenance.
Regularly check the air filters for cleanliness or
when a filter alarm is indicated on the control
interface.
Cleaning the Condenser Coils
Clean the coils at least once a year or more
frequently if unit is located in a dusty and/or dirty
environment, in order to maintain your system’s
proper operating performance. High discharge
pressures are a 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.
Outdoor Maintenance
Do not obstruct airflow to the outdoor coil to
ensure your air conditioner operates efficiently.
Use light detergent solutions to clean the surface
of the panels. Repaint corroded panel surface, as
required.
Live Electrical Connections !
It may be necessary to work near live
electrical components on certain maintenance
tasks. Only qualified technicians, who are
competently trained, are allowed to perform
service tasks.
DANGER
Hazardous Voltage !
• Always make sure that all power supplies,
including remote controls, are isolated before
performing maintenance.
• Beware of EC Motors with high power
capacitors and which can have dangerous
voltages at terminals for up to 5 min. after
main power has been isolated. Wait at least
5 minutes after power isolation and test for
high voltage before performing service work.
• EC Plug Fan has dual power supplies, i.e.
415V / 3Ph+N / 50Hz motor power supply plus
10VDC control power supply. Care must be
taken to ensure both are safely isolated to
prevent personal injury and damage to the
equipment.
•
Observe proper Lock-Out / Tag-Out
procedures to ensure that power cannot be
inadvertently energised.
• Failure to isolate power before maintenance
procedures can result in serious injury or
death.
