WHEN PUMP STARTS AND BEGINS SUCKING WATER OUT OF RESERVOIR, AN AIRLOCK WILL BE CREATED
UNLESS AN AIR INTAKE OPENING IS PROVIDED ON TOP OF RESERVOIR. BECAUSE CONDENSATE FLOW
FROM DRAIN PAN INTO RESERVOIR RELIES ON GRAVITY, RESERVOIR MUST ALWAYS BE BELOW DRAIN
PAN AND IT IS POSSIBLE THAT A BLOCKAGE MAY CAUSE THE WATER LEVEL IN
THE CONDENSATE DRAIN INLET HOSE BETWEEN PAN AND RESERVOIR TO BACK UP
UNTIL IT GETS HIGHER THAN THE TOP OF THE RESERVOIR. IF THIS HAPPENS,
THE WATER WILL BLEED OUT OF THE AIR INTAKE OPENING AND TO PREVENT

All pump models incorporate a filter in the
reservoir which must be cleaned regularly.
A detailed explanation of this will be
found in diagram C below.
All pump models require a mandatory
breather tube to prevent an airlock in the
reservoir while the pump is operating.
A detailed explanation of this will be
found in diagram D below.
ASPEN Mini models are available in
24V, 115V and 230V AC.
ASPEN Maxi models are available in
115V & 230V AC only.
If the current in the communication wire
is low voltage electronic or DC, it will
generally be difficult or impossible to
isolate the other leg required to operate
an alarm, and in this case, the orange
wire is simply taped up and not used.
Connection details for an external
alarm will be found in diagram A
below.
Generally, most installers do not connect
up an external alarm and this is why our
wiring diagrams show the orange wire
being taped off and not used.
NOTE THAT THE OVERFLOW ALARM
CIRCUIT NEVER DEACTIVATES THE
PUMP WHICH REMAINS LIVE AT
ALL TIMES.
The power supply to the pump should
always be connected to the incoming
power terminal block on the evaporator
to ensure that the pump is powered
whenever the evaporator is powered.
It is not a good idea to hard wire the
pump from a separate circuit, or to power
it from a receptacle like a conventional
tank pump because either of these can be
inadvertently isolated or the plug could be
accidentally removed.
In either case the evaporator would
continue to produce water, but there
would be no power to operate the pump
or the overflow switch, so a flood would
occur and this is unacceptable.
In spite of this, some local codes actually
call for this type of wiring connection and
if local code officials insist, this
requirement will have to be met even
though it may contradict the Aspen wiring
instructions.
Some codes also require a disconnect
close to the evaporator and, if this is
installed, sometimes the pump is powered
directly from the disconnect. In this case,
it is vital that the pump is powered
from the outgoing terminals on the
disconnect, not the incoming ones,
to ensure that if the evaporator is
isolated, the pump will be isolated
as well.
Details of this will be found in
diagram B below.
All manufacturers of Minisplit air
conditioners use different wiring protocols,
so the communications wire varies from
one unit to another, as well as from one
model to another, and for this reason, all
wiring diagrams in the installation
manuals are generic.
Consult EZ-TRAP for factory
approved wiring diagrams for all
the major manufacturers. These
