CAUTION:
In this installation, hoses connecting between ports of overflow protection
pressure switch (overflow switch) and pressure tabs on the collector box
MUST be switched. The overflow switch has two ports, which is different
from two other regular pressure switches that have only one port.
Make sure that black port (positive) is connected to the lower position tap
on condensate collector box and gray port (negative) to higher tap of
condensate box. Connecting incorrectly will result in failure to protect
condensate overflow.(See Fig. 16)
