TRAP publications: Pump Selection Specifications (on page 4)
and Pump Selection Guide for correct type & model number, and Installation Guidelines for optimum piping layout.
Regardless of type or size, all ASPEN Minipumps (Mini & Maxi Lime, Mini & Maxi Orange,
and Mini Aqua) share an identical operating sequence:

1. Pump is in Standby Mode:
Unit is not operating, float rests on bottom of
reservoir, overflow switch status is normal so
contacts across gray and purple wires are closed
and communication wire from condenser to
evaporator remains energized.

2. Pump enters Operation Mode:
The evaporator produces water
which flows into the drain pan and
through the drain hose into the
reservoir lifting the float 3/4” which
automatically activates the pump.
Pump continues operating until
water level recedes, float returns to
the bottom of the reservoir, at
which point the pump automatically
switches off.
Overflow switch status
is normal so contacts
across gray and purple
wires are closed and
communication wire
from condenser to
evaporator remains
energized.
This cycle will repeat
indefinitely as long as
water level in reservoir
stays within normal
limits.
3. Pump enters Alarm Mode:
The evaporator produces water
which flows into the drain pan and
through the drain hose into the
reservoir lifting the float 3/4” which
automatically activates the pump.
Even though pump is operating,
water level continues to rise because
of pump failure,
blockage or insufficient
capacity of pump.
Water level reaches
15/16”, overflow switch
operates changing
status to abnormal.
Pump remains activated
but contacts across gray
and purple wire open,
de-energizing
communication wire to
evaporator so it can no
longer operate.
This prevents unit from
creating any more
water and raises an
alarm because occupant
will soon notice that
AC is not operating
and will contact service
tech to investigate.
Normally open contacts (gray and
orange) close, current flowing into
the evaporator from the condenser is
now diverted to energize the orange
wire which is normally taped off, but
may also be wired into an external
alarm if desired (see diagram A).
4. Pump reverts to Standby Mode:
Once reason for high water level has been
diagnosed and corrected, pump reverts to standby
mode, unit not operating, float rests on bottom of
reservoir, overflow switch status is normal so
contacts across gray and purple wires are closed
and communication wire from condenser to
evaporator remains energized.
