6.11 LOW WATER CUTOFF (LWCO) CAPACITOR INTEGRITY TEST
The LWCO capacitor should be tested for electrical shorts every 12 months and replaced,
then tested, every 24 months. The LWCO capacitor integrity test consists of two parts, as
described in the next two sections. The first procedure explains how to test for electrical
shorting of the LWCO probe capacitor, while the second procedure instructs how to perform
the standard Low Water Cutoff test using the C-More controls.
On the Recon series, the LWCO probe is located on the heat exchanger body on the left side of
the unit. Refer to Figure 6-12 for an illustration of the LWCO probe assembly and its installation.
