Water Switch (“Flow Control”) (1)
Water Switch (“Flow Control”) (1)
All Apexx (SH_99) and ExactWash (SHX/Y56 & SHV/Y66)
model heater assemblies have motor operated water switches
inside them, with motors attached where Top Rack Only
housings have been traditionally mounted (underneath heater
assemblies). They consist of a motor-controlled disk (with 3
holes) which rotates to provide precise water flow control --
using both spray arms, upper spray arm only or lower spray
arm only.

HINT: Models with water switches require
stronger circulation pumps (# 239129) with
separate motor starters (# 182318).
Circulation pumps, heaters & sumps for
water switch and non-water switch models
cannot
be interchanged.

HINT: Models with water switches and
Top Rack Only have the Top Rack Only
