Condensate Pump

The condensate pump, mounted in the bottom of most units, is
used for unit drain water only. The condensate pump is complete
with sump, motor and pump assembly and automatic control.
The standard model has single float. A dual-float condensate
pump, which includes connections to unit, common alarm, unit
shutdown and one customer N/O contact is also available.

Remote Temperature/ Humidity Sensors

The remote temperature/ humidity sensors permit monitoring room conditions from an external
source. They are encased in an attractive case and are provided with a plug compatible shielded cable
in virtually any length.
4.6.3 Disconnect Switch—Locking Type
The locking disconnect switch, mounted in the electrical panel, is con-
nected to the safety lock dead front panel of the system and is inter-
locked mechanically. In this way the panel can't be opened until the
switch is in the off position. And it complies with local codes as well as
those of the NEC.
