Spray Arm Assembly
The spray arm is mounted to the upper pump housing_Water from the sump is pumped through the upper pump
housingwhere it isdirected to the spray arm..The water is discharged from ports in the spray arm as shown in Figure
t5..
The velocityof the water discharged from the ports and the angle of the port opening causesthe spray arm to rotate.
The rotation of the spray arm assuresthe distribution of water to all corners of the tub,
A stuck or split spray arm can cause ieaks or poor washability. On complaints of this type, inspect the spray arm
closely for a possible split seam. Be sure the spray arm turns freely on the pump housing. If binding is encountered,
it wilt be necessary to replace the pump housing or spray arm, or both°
5pray Tube
The spray tube or middle spray arm directs water to the upper rack to assure complete washing and rinsing of all
plates and glassware. Water ispumped from the sump, by the lower impeller, through a hoseconnected to the spray
tube or middle spray arm,
On models having the upper rolo rack, be certain the racks turns freely. Unsatisfactory washing of the items in the
upper rack will result if the rack binds, is prevented from rotating by a tall item in the lower rack, or water is not
being discharged from the spray tube..
