1. Turn off all sources of power to the fan coil unit.       ESPV
2. Remove access panel.
3. Refer to Figures and mark the location of the drain
pan where the float switch will be mounted. Dry and
clean the bottom of the drain pan with alcohol.
4. Remove the paper from the adhesive strip on the
float switch bracket. Locate and press the bracket into
position on the drain pan surface. In the corner of the
drain pan closest to the AFS (Ant-Frost Switch). Hold
at least 3 minutes while applying hand pressure.
5. Cut one of the wires leading to the AFS. Splice the
float switch wires in series with the AFS wire, such
that the connections are not allowed to come in
contact with water in the drain pan.
6. Leave sufficient slack in wires to avoid tension on
the connections shown. Use the cable tie to secure
the float switch and AFS wires together.
7. Using a continuity meter, check that the circuit is
closed (no resistance) when the float switch is in the
normal (low water) position. Check to see that the
circuit is broken (open) when the float switch is raised
to the up (high water) position.
8. Re-install the control box cover and all access panels.
9. Turn on all power sources to the unit. Check that the
blower and condensing unit are operational.
