Wye Strainer
Purpose: A wye strainer is provided with the chiller. It should be installed on the return line to catch
particles in the fluid.
Maintenance: If the return pressure is above 15 psi, clean the wye strainer.
Condenser Coils
Maintenance: Dust and debris may collect on the condenser during normal operation. Accumulated
debris restricts air flow and reduces heat transfer which affects chiller performance. Use a brush to
loosen compacted debris and use a vacuum to collect the debris.
Electrical Inspection
Maintenance: Use a multimeter to check electrical values. Take measurements at contactors or
terminal blocks. Compare values to the chiller or component name plate. Chillers include a phase
monitor. Refer to the fault indicators provided on the phase monitor and contact a licensed electrician
to correct any faults.
