3.8 Condensate Pumps
A condensate pump is optional. Factory mounted pumps are pre-wired. While no outside power
source is required, eld piping is still a requirement.
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
One (1) condensate probe for sensing water under the oor is standard and 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 accu-
mulate. 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 standard hookup wire may be used if required.
WARNING: Failure to remove the condensate probe from the plastic bag and
uncoil the length of wire attached to the probe will leave the unit unprotected
for sensing water under the unit and 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 in addition to or in lieu of the con-
densate probe. 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.
