Waterous Arizona Operations 500-100 & 120-P Operations Rev 1Page 11 of 30C. Wye Strainer for CoolerA wye-strainer is provided to strain water before it enters the cooler's water inlet. The wyestrainer requires regular inspection, and should be in an easily accessible location forinspection, removal, and cleaning.Caution: Waterous is not responsible for damage due to plugged strainers. If thecustomer's water system contains excessive debris, or the vehicle relies ondrafting for its water supply, it may be necessary to install a larger strainerand/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 waterflow. It will allow debris into the cooler, which can clog the tiny heat exchanger tubes andrestrict water flow.Figure 2 Wye Strainer Figure 3 Wye-strainer installed, withcleanout valve.Figure 4 Clean Strainer Figure 5 Dirty Strainer
