4 inlet holes are located in the top deck of
the pump. Flexible vinyl tubing or PVC may
be connected to any of the pump inlets.
Knock out covers are provided to cover
unused inlets. Be sure to knock out only the
hole used for the inlet pipe to prevent the
pump from collecting debris or insects.
Tubing installed into the inlet holes must be straight. The tubing must not
bend inward where it will interfere with the pump or oat mechanism.
When using rigid tubing such as PVC, be sure to cut the end at an angle.
This will allow the condensate water to drain freely and keep the tubing
end from being blocked by the tank bottom.
It may be desirable to use a “P” or “U” trap between the AC unit and the
condensate pump to provide a liquid barrier to air ow from the air condi-
tioner. These types of “traps” always contain some water which blocks the
ow of air from the AC unit which is wasteful and can cause other prob-
lems such as accelerated algae growth.
The pump is equipped with a combination barb-type tting and check
valve. The tting allows the connection of 3/8” exible vinyl tubing such as
DiversiTech “CVT” clear vinyl. Attach the tubing by pressing it over the
barb tting and secure with a screw type hose clamp.
Route the tubing up and away from the pump; avoid compressing or
kinking the tubing. The tube route should be the shortest possible distance
from the pump to the building exterior or other drain location. For best
results the distance that the water must go UP should be shorter than the
distance that it goes DOWN. With the longer DOWN tubing, the length will
help siphon the condensate from the tank, speeding the pump out time.
Connect the pump power to a properly grounded outlet capable of
providing power that exceeds the requirements listed on the pump name-
plate. Avoid the use of extension cords wherever possible. The pump must
be operated by a continuous source of power and must not be connected
to switched outlets or other power supplies that may be inadvertently or
automatically turned o.
All aspects of the installation must conform to requirements of the NEC,
and any applicable local codes.
The pump safety switch should be used
on 24V Class II control circuits only. The
pump safety switch connections are
to be connected in series with the 24 Volt
thermostat circuit to shut o A/C systems
should an overow condition occur. An
optional DiversiTech Universal Alarm may
be connected to indicate system trouble.
