All anchors for
mounting the equipment must be placed and sized to
ensure a safe and durable installation. When neces-

On 7-1/2 to 20 ton horizontal units, the YSHW blower
coil units are intended to be mounted thru the top of
the unit. There are 7/8” knockouts located at all four
corners top and bottom which permits fi eld supplied

Any devices such as fan switches or
thermostats intended for fi eld installa-
tion must be wired in strict accordance
with the wiring diagram that is sup-
