Periodic Maintenance
General
Perform all maintenance procedures and inspections at
the recommended intervals. This will increase the life of
the chiller and minimize the possibility of costly failures.
Weekly Maintenance
After the unit has been operating for approximately
30 minutes and the system has stabilized, check the
operating conditions and complete the procedures below:
1. Check on the TD7 pressure for evaporator, condenser,
and intermediate oil.
2. Inspect the entire system for unusual conditions and
inspect the condenser coils for dirt and debris. If the
coils are dirty, refer to coil cleaning.
Monthly Maintenance
1. Perform all weekly maintenance procedures.
2. Record the system subcooling.
3. Record the system superheat.
4. Make any repairs necessary.
Annual Maintenance
1. Perform all weekly and monthly procedures
2. Check the oil sump oil level while the unit is off.
Note:
Routine changing of the oil is not required. Make an
oil analysis to determine the condition of the oil.
1. Have Trane or another qualified laboratory perform
a compressor oil analysis to determine system
moisture content and acid level. This analysis is a
valuable diagnostic tool.
2. Contact a qualified service organization to leak-test
the chiller, to check operating and safety controls, and
to inspect electrical components for deficiencies
3. Inspect all piping components for leakage and
damage.
4. Clean and repaint any areas that show signs of
corrosion.
5. Clean the condenser coils.
6. Clean the air filter located on the door of the control
panel of AFD only on following unit type:
- RTAF HSE sizes 155 and 175 on circuit 1
- RTAF HSE sizes 190 and 205 on each circuit
7. Check and tighten all electrical connections as
necessary.
CAUTION!
A clear sight glass alone does not mean that
the system is properly charged. Also check the rest of the
system operating conditions.
WARNING!
Position all electrical disconnects in the
“Open” position and lock them to prevent injury or death
due to electrical shock.
Refrigerant Emission Control
Conservation and emission reduction can be
accomplished by following recommended Trane
operation, maintenance, and service procedures,
with specific attention to the following:
1. Refrigerant used in any type of air-conditioning or
refrigerating equipment should be recovered and/or
recycled for reuse, reprocessed (reclaimed). Never
release refrigerant into the atmosphere.
2. Always determine possible recycle or reclaim
requirements of the recovered refrigerant before
beginning recovery by any method.
3. Use approved containment vessels and safety
standards. Comply with all applicable transportation
standards when shipping refrigerant containers.
4. To minimize emissions while recovering refrigerant,
use recycling equipment. Always attempt to use
methods that will pull the lowest possible vacuum
while recovering and condensing refrigerant into
containment.
5. Refrigerant-system cleanup methods that use filters
and dryers are preferred. Do not use solvents that
have ozone depletion factors. Properly dispose of
used materials.
6. Take extra care to properly maintain all service
equipment that directly supports refrigeration
service work, such as gauges, hoses, vacuum
pumps, and recycling equipment.
7. Stay aware of unit enhancements, conversion
refrigerants, compatible parts, and manufacturer’s
recommendations that will reduce refrigerant
emissions and increase equipment operating
efficiencies. Follow the manufacturer’s specific
guidelines for conversion of existing system.
8. In order to assist in reducing power-generation
emissions, always attempt to improve equipment
performances with improved maintenance and
operations that will help conserve energy resources.
Refrigerant and Oil-charge
Management
Proper oil and refrigerant charge is essential for proper
unit operation, unit performances, and environmental
protection. Only trained and licensed service personnel
should service the chiller.
Some of the symptoms of a refrigerant under-charged
unit:
•
Larger-than-normal evaporator approach temperatures
(leaving water temperature – saturated evaporator
temperature). If the refrigerant charge is correct the
approch temperature is between 1°C and 1.5°C on circuit
1 and between 2°C and 2.5°C on circuit 2.These values
are given for units running at full load and with water
without antifreeze
•
Low Evaporator-refrigerant temperature limit
•
Low Refrigerant-Temperature cutout diagnostic
•
Fully-open expansion valve
•
Possible whistling sound coming from liquid line
(due to high vapor velocity)
