WARNING: The condensate drain MUST be connected to an external drain line (provided
by others) before unit start up. Without eld piping condensate water will damage internal
components.
Condensate pumps which ship loose normally require a separate source of power. Always check
the pump power requirements before connecting power. Condensate pumps are available in various
voltages.
Factory installed condensate pumps are wired to display a “HIGH CONDENSATE WATER LEVEL”
alarm. The wiring for this must be done in the eld on pumps that ship loose.
3.9 Condensate Probe
A condensate probe for sensing under oor water is included with this unit. This comes in a plastic
bag with about 15 feet (4.6 m) of coiled-up wire. The condensate probe is a rectangular box that is
typically placed below the unit in a location where the water is likely to accumulate. Additional probes
are available as an option.
Place the probe at on the oor on top of a thin layer of non-conductive silicone. Secure the attached
wires where necessary. A longer length of wire may be used if required.
WARNING: Failure to remove from the plastic bag and uncoil the length of wire attached
to the condensate probe can result in a nuisance water detected alarm. Remove/
disconnect the probe if it is not to be used.
3.10 Water Sensing Cable (Optional)
Some units may be equipped with an optional water detection cable. The cable can sense moisture
anywhere along its length. It is typically placed below the unit in a rectangular pattern that matches
the perimeter of the unit. The cable is connected to the terminal board and ready for installation.
Cable lengths will vary depending on the original order and specications. Care should be taken when
installing the cable. Be sure the cable is not touching metal and/or any debris under the raised oor.
3.11 Remote Temperature and Humidity Sensors (Optional)
Remote temperature and humidity sensors are optional. Although existing unit mounted sensors can
be removed for remote mounting, the remote sensor option provides a more convenient means of eld
installation. This is because the sensors are already connected to a predetermined length of cable and
come mounted in a remote sensor enclosure. The temperature and humidity sensors require a total of
ve wires and should be twisted, shielded cable type.
