GENERAL
Use the two--part accessory kit (condensate pump and detection
unit) with high wall fan coils. The pump operates whenever the
condensate level in the detection unit is high enough to cause the
magnetic float switch to send a signal to start the pump.
The float switch in the detection unit also prevents overflow and
can act as a safety device by shutting down the system. The
detection unit comes with normally closed (NC) alarm contacts
(user optional, but recommended). The normally closed alarm
contact is a dry contact rated for 8 amps at 250 volts. In the event
of a problem such as a clogged drain or pump discharge line, the
alarm contact can be wired to shut down the entire system. The
condensate pump provides 10 ft (3.0 m) maximum suction lift
(A)--Fig. 2.

INSTALLATION
Refer to Fig. 1 and Table 1 for kit content.
NOTE: To make the installation easier, install the detection unit
assembly before installing the fan coil unit.
1. Unpack the contents of the condensate pump accessory
package. Attach the 5/8--in. rubber elbow and transparent
vent tubing to the detection unit (see Fig. 6). If straight
connection is required, rubber elbow can be cut to size.
Do not use a tube longer than the one supplied with the kit
(2.95” / 75 mm). Slide the mounting bracket onto the bot-
tom of the detection unit. Uncoil the low voltage power
cord.
2. Remove the fan coil mounting bracket from the back of
the unit. Connect the detection unit with the 5/8--in. elbow,
to the condensate drain line (see Fig. 6).
3. Peel the adhesive cover on the back of the detection unit
mounting bracket and attach it to the inside of the unit ad-
jacent to the fan coil drain as shown in Fig. 6. Make sure
the detection is installed horizontally for proper opera-
tion of the float switch.
4. Attach one end of the transparent tubing to the detection
unit. The tube can be connected to either the front or the
rear as shown in Fig. 3. block the unused outlet with the
plug supplied.

5. Connect one end of the low voltage power cord to the tele-
phone jack socket in the detection unit and route the cord
and transparent drain tubing through the knockout on the
side of the unit enclosure (see Fig. 6).
6. Determine the mounting location of the pump assembly.
The pump assembly must always be above the level of
the detection unit. For best operation, it is recommended
that the pump assembly be mounted in a vertical position
with the flow arrow on the pump pointing up (see Fig. 7).
Do not exceed 10 ft. (3.0 m) maximum suction lift.
NOTE: in most applications, the pump will need to be mounted
outside of the highwall unit for proper orientation ( i.e. above
drop ceiling).
7. Screw the bracket to the wall and attach the pump to the
bracket as shown in Fig. 4 and Fig. 5.

If the pump is not mounted in the vertical position, make sure that
plug on the pump is above the refrigerant tubing. This is required
to avoid water leaking onto the pump causing a short circuit. The
pump cannot be splashed nor located in a damp
environment.
