Critical Cleaning Tasks
Monitor temperature change and pressure drops
across the evaporator and condenser circuit to
determine the frequency for strainer cleaning. Monitor
water quality in the chiller’s closed system to
determine the optimum frequency for evaporator
cleaning.
On multiple module chillers, Trane provides service
isolation valves on each evaporator to isolate each
strainer for cleaning without disrupting the operation
of any remaining modules in the chiller.
Strainer Cleaning Procedure
Strainers at each evaporator are critical for protecting
the brazed plate heat exchanger’s small water
passages as well as maintaining water/glycol mixture
cleanliness. Service valves on the evaporator isolate
each strainer for cleaning without interrupting the
operation of other modules in the chiller bank. If a tank
and pump module is provided, pot strainers are
occasionally included on the pumps’ suction lines.

1. De-energize power to the module containing the
strainer by turning the power OFF at the breaker
and/or disconnect.
2. Close the two service isolation valves between the
header and the evaporator.
N No otte e:: If this is a variable flow chiller, the outlet may be
equipped with an electronic valve that must be
manually locked in the closed position.
3. Remove the insulation to expose the roll grooved
blind end cap or service cap on the end of the
strainer housing. Utilize a short section of hose to
connect to the valve on the end cap to relieve
pressure and capture fluid. (Dispose of or re-utilize
water/glycol mixture according to local protocols.)

4. Inspect the gasket and service cap for abrasions,
tears, excessive dirt, or deterioration. Replace
gasket if necessary.
5. Remove the strainer from the housing.
6. Clean the strainer inside and out using a soft
natural bristle brush and tap water.
7. Clean the interior of the end cap (or service cap),
and the gasket using a soft natural bristle brush and
tap water. Apply a light coating of lubrication to the
gasket.
8. Re-install the strainer in the housing (large end
first). Replace the gasket and end cap and tighten
coupling collar securely.
9. Ensure the water/glycol make-up system is
operational to replenish the water/glycol mixture
lost during the cleaning process.
10. Energize power to the module containing the
strainer by turning power ON at the breaker and/or
disconnect.
Condenser Cleaning Procedure
Fouling of condenser will result in a gradual decline in
performance of the chiller and is particularly significant
during high ambient operation:
1. Turn off and “lock out” the power to the chiller
module or remote condenser.

2. Remove fan assembly to improve access to
condenser coils.
3. Use a garden hose with spray nozzle or a long spray
wand with a 90° turn spray head. (DO NOT use a
pressure washer on condenser coils).
N No otte e:: If chiller is equipped with EC-type fan motors,
remove the compressor-side V-baffle end cap,
instead.

4. Clean coils by spraying water in the opposite
direction of the air flow, from top of the coil to the
bottom. Spray in a consistent pattern to work the
dirt and debris from the top to the lower part of the
coil.
