Make certain pressure is relieved from air tubing. Close the air supply valve and open
vent valves on air manifolds. Wait until air pressure gages read zero.
Make sure electrical power is disconnected before working on unit. Failure to do so
could result in serious injury or death from electrical shock.
There are three low pressure solenoid valves located as shown in Figures 4-58, 4-59
and 4-60. The removal and installation procedures for Figures 4-58 and 4-59 are
identical. Procedures for Figure 4-60 are covered separately.
