1. Chiller
☐ Installation meets foundation requirements.
☐ In place and piped.
☐ Isolation pads or elastomeric pads installed
(optional).
☐ For units with InvisiSound™ Ultimate Option (model
number digit 13 = E), compressor mounting bolts
have been removed.
2. Refrigerant Pressure Check
☐ PRIOR to water being pumped into system, use
gauges to verify positive pressure in the evaporator
and condenser. Lack of pressure could indicate a
system leak. When charging in the factory,
approximately 95% of the refrigerant charge is
isolated in the evaporator, and the other 5% is
120
contained in the condenser and compressor. If no
pressure is present, contact local Trane service.
Note: Verification must be done by gauges. Do NOT
rely only on values from unit controls.
