Sintesis™ Air-Cooled Chiller: Weekly Maintenance

Preventive maintenance is a simple and cost-effective way to ensure your HVAC system is running at peak efficiency and to catch problems before they get serious.

Maintenance

! WARNING

Hazardous Voltage w/Capacitors!

Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury. Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/ tagout procedures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided by Trane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for dis

This section describes the basic chiller preventive maintenance procedures, and recommends the intervals at which these procedures should be performed. Use of a periodic maintenance program is important to ensure the best possible performance and efficiency from a Sintesis™ chiller.

Use Operator Log in Log and Check Sheet chapter to record an operating history for unit. The log serves as a valuable diagnostic tool for service personnel. By observing trends in operating conditions, an operator can anticipate and prevent problem situations.

If unit does not operate properly during inspections, see Diagnostics chapter.

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.

At AdaptiView™ TD7 or Tracer™ TU service tool, check pressure for evaporator, condenser and intermediate oil.
Observe liquid line sight glass on EXV. If liquid line sight glass has bubbles measure the subcooling entering the EXV. Subcooling should always be greater than 10°F.
Important: A clear sight glass alone does not mean that the system is properly charged. Also check the rest of the system operating conditions.
Inspect the entire system for unusual operation.
Inspect the condenser coils for dirt and debris. If the coils are dirty, see “Microchannel Condenser Coils,” p. 92.
Ensure exterior of panel enclosures (including remote VFD, if installed) are clear of any dust or debris.

NOTICE:

Coil Damage! Do not use detergents to clean coils. Use clean water only. Use of detergents on coils could cause damage to coils

Important: Panel cooling air lets must be regularly inspected and kept clean and free of debris. Failure to do so can cause reduced cooling to drives, resulting in unit trips on drive over-temperature.
