Pump Disassembly
The pumps must be disassembled for installation.
Remove the four screws on the bottom.
Remove the original pump cover. Make sure the
original o-ring stays seated on the pump. This o-ring
is required for the RP-401X2.

There are two locations in the top edge of the
acrylic window for 3mm wide LED lights (sold
separately). Slide each LED into the small
receptacles in the edge of the acrylic. A small
drop of hot glue can help hold each LED in
place.
LED Lighting (Optional)
Using Serial or Parallel Loops
The front reservoirs
can be left separated
(parallel) or combined to form one reservoir.
Combining is done by removing a plug
underneath. The plug should be left it in place
to keep the reservoirs separated.
Access the plug by removing the front metal
cover plate beneath the RP-401X2. Be sure
to leave its black o-ring in place.
O-ring
If you need to remove the pump blocker,
unscrew its four short screws. This is only
necessary when installing two pumps.
Remove the fill port
and replace the metal
plate. Keep the o-ring
in place.
O-ring
Serial Connector (Optional)
To allow for cleaner plumbing when running
two pumps in series, a Koolance “180-
Degree Connector” is available (sold
separately). This pipe is installed on the
back, and its new acrylic piece is installed
into the front left reservoir to improve flow.

To mount the second pump, repeat the
previous process for the opposite side of
the RP-401X2.
The pump blocker includes its own
o-ring. DO NOT USE this if a pump
will be installed here. Instead, use the
original pump’s o-ring.

Pump #2 (“P2”)
Operation with One Pump
The RP-401X2 is shipped with one pump
side “blocked”. Leave this in place with its
screws and o-ring if you are only installing
one pump.
Pump blocker
Place the pump in the desired location
and attach with the longer screws
included with the RP-401X2. The
pump wire must exit the back end of
the reservoir.
In addition, the inlet and outlet of this pump
must stay plugged on the rear nozzle ports
to prevent leaking.
CAUTION: To prevent leaking while using one pump, make sure the
pump blocker remains installed with its screws and o-ring. The rear inlet
and outlet ports for this absent pump must also remain plugged.
!
NOTE: If your pump version has
feet on the plastic base, these
must be removed in order to fit
the RP-401X2.
