WARNING The condensate drain MUST be connected to an external facility
drain line (provided by others) before unit start up. Without field piping
condensate water will damage internal components.
A factory installed condensate pump come pre-wired and setup to display a “HIGH CONDENSATE WATER LEVEL”
alarm. The wiring for the alarm must be done in the field on a pump that ships loose.
Condensate Probe (Standard on Floor Units and Optional on Ceiling Units)
A condensate probe for sensing under floor water is included with all floor units. Additional condensate probes
may be added. The probe comes pre-wired and located in a plastic bag with approximately 8 feet (2.4 m) of coiled-
up wire inside the electrical control panel. The probe has a flat plate on the bottom that is typically placed below
the unit in a location where the water is likely to accumulate.
Place the probe flat on the floor using a thin layer of nonconductive silicone or calking. Secure the attached wires
to prevent accidental snagging where necessary. If a longer length of wire is needed, standard hook-up wire may
be used if required.
NOTICE Failure to remove the probe from the plastic bag, uncoil the length of
wire attached to the condensate probe and locate the probe under the unit,
can result in a nuisance water detected alarm.
Float Switch (Ceiling Units)
Ceiling units come standard with a factory pre-mounted and wired condensate pan overflow detection float switch
located in the condensate drain pan. If needed, an optional flow switch can be ordered to be used as a secondary
condensate drain pan alarm. Consult factory for details.
Under-Floor Water Detection Cable (Optional)
Another option for water sensing is the Under-Floor Water Detection Cable. This is a special long cable that can
sense moisture anywhere along its length. It is typically placed below the unit in the secondary containment pan a
rectangular pattern that matches or slightly larger than the perimeter of the unit. The cable is pre-wired to the
appropriate terminal connection inside the electrical control panel and ready for field installation. Cable lengths
vary depending on the length ordered. Typically, the cable is installed around the unit perimeter. Care should be
taken when installing the cable. The two water sensing wires are covered by a nonconductive polymer weave. This
weave isolates the cable from metal surfaces. However, as with all electrical wires and cable, avoid sharp objects
that can slice or pierce through the insulation and nonconductive polymer weave.
Disconnect Switch (Optional)
A thru-door locking disconnect switch is an optional feature which includes a non-automatic trip disconnect switch
with handle mounted in the high voltage section of the electrical control panel. The handle prevents access to the
high voltage electrical components until the disconnect switch is turned to the OFF position. The handle protrudes
through the exterior door and can be locked with a field supplied padlock in the OFF position for safety during
servicing the unit.
