Wye Strainer For Cooler - Waterous 80-P Operation Manual

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:
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.

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.
