8. Be certain that the bottom of the reservoir is within (+/-) 8 degrees of being level with the optimum performance being
when the reservoir is level. Use care to ensure the reservoir will remain level throughout its operating life. If the reservoir
is not mounted properly, the float mechanism may not function properly and may cause the unit to overflow.
THE EC-1 PUMP IS NOT SUBMERSIBLE. Ensure that it is located where water cannot be splashed, sprayed, or dripped onto
it.
DO NOT locate the pump near insulation or other flammable material.
1. Determine a suitable location to install pump. Pump can be located above, below or adjacent to air handler.
a. The maximum suction lift of the pump is 3 ft (1m), therefore the control unit/pump cannot be installed more than
3 ft (1m) higher (vertically) than the collection reservoir.
2. Using the supplied mounting bracket, secure bracket to wall using supplied wall anchors and screws.
3. Using one of the supplied #4 x 1" long self-tapping screws, insert the end of the screw into the hole of the mounting
grommet in the pump bracket and work the point down to pierce through the mounting grommet. Perform this step
for the second mounting grommet.
4. Place the pump mounting bracket against the wall and use the points of the screw to mark the wall in locations to
drill for the wall anchors.
5. If using the supplied wall anchors, drill a 3/16" (5mm) hole x 1" (26mm) deep at each point marked on the wall, then
insert an anchor fully into each hole.
6. Using the supplied screws, attach the mounting bracket to the wall. Hand-tighten the wall anchor screws against
rubber grommet, being careful so that screw head does not push through rubber grommet.
7. Slide pump onto wall bracket by inserting slots of bracket into flanges of black mounting grommets on side of pump
housing.
8. Connect the sensor cable from the collection reservoir to the control unit/pump by inserting the cable connector into
the corresponding socket on the control unit/pump.
Drain Hose-to-Reservoir Inlet Tubing:
1. Connect 1⁄2" ID x 3" (12mm ID x 76mm) tubing to the air handler drain hose.
2. If the air handler's drain hose has a plastic adapter suitable for use with reservoir inlet tubing, there is no need to
use the stepped adapter to connect drain hose to reservoir inlet. If the drain hose has a plastic adapter not
suitable for use with the reservoir inlet tubing, it may be necessary to cut the hose and remove the adapter.
Connect the single-sized end of stepped adapter to the inlet tubing, and fit the stepped adapter to the drain
hose. The adapter fits 1/2", 5/8", and 3/4" (14mm, 16mm, 18mm, 20mm) drain hose ID. Use a cable tie or hose
clamp to secure the drain hose to the adapter.
3. If the condensate drain has a metal drain port, such as on a fan coil, use the supplied adapter and connect it to
the metal drain port using a flexible hose (not supplied).
4. Be certain to support the reservoir when attaching tubing and that tubing is not kinked when reservoir is in place.
