C. Wye Strainer for Cooler
A wye-strainer is provided to strain water before it enters the cooler's water inlet. The wye
strainer requires regular inspection, and should be in an easily accessible location for
inspection, removal, and cleaning.
Caution:
Waterous is not responsible for damage due to plugged strainers. If the
customer's water system contains excessive debris, or the vehicle relies on
drafting for its water supply, it may be necessary to install a larger strainer
and/or a clean-out valve on the wye-strainer.
Without good water flow through the heat exchanger, the compressor will overheat.
Compressor performance will be inadequate, and it may fail completely.
Omitting the Wye-strainer or removing the screen from the Wye does not improve water
flow. It will allow debris into the cooler, which can clog the tiny heat exchanger tubes and
restrict water flow.
