Locate the outdoor unit in a suitable location, as close as
possible to the fan coil. Maintain the clearances recommended by
the manufacturers of the outdoor unit, to ensure proper airflow.
The outdoor unit must be installed level, in a properly supported
location. A liquid line filter/drier is recommended to be installed.
Outdoor Unit Installation
Make all connections to the outdoor unit with rain tight conduit
and fittings. Most building codes require a rain tight disconnect
switch at the outdoor unit as well (always check local codes). Run
the proper size copper wires to the unit, and connect as per the
manufacturer’s recommendations.
Ensure that the outdoor unit is setup for a TX system. If not, a
hard start kit may be required.

Mounting the RPM-E

Two L mounting brackets are shipped loose for attaching the
RPM-E to the fan coil, along with two sided foam tape for an air
seal between the units. When mounting the cooling coil to the
fancoil (Fig. RPM-04), ensure that no screws puncture the drain
pan or coil. It is advised that no screws be placed within 3 inches
(76mm) from the bottom of the coil. This will prevent the drain
pan from being accidentally pierced. It is also advised that care be
taken when placing screws in the top left side of the cooling coil
(when looking at the access hatch), as this is where the top most
extent of the cooling coil is located. See Specification Pages for
the dimensions of the fan coil units and cooling modules.

The primary condensate drain
must have a minimum 3”
P-Trap installed
(Fig. 05). The drain line must run at a slope of
¼” per foot in the direction of the drain. RPM-E modules come
with a ¾” male CPVC primary and secondary outlet. It is good
practice to install a clean out right above the P-Trap. Using a
“tee fitting” and cap in the P-Trap’s construction can be used as
the clean out and as a way to prime the P-Trap if it ever dries out.
A wet P-Trap is important.
A dry P-Trap can be detrimental to
proper drainage. If code requires a secondary drain line, run the
secondary line using the same method as primary. Otherwise,
capping off the secondary drain line is acceptable. Do not run the
secondary drain line to the secondary drain pan or use it as a vent
to atmosphere! An equipment stand/riser or rubber equipment
mat may be necessary to elevate the module off of the ground to
allow for a P-Trap.
Any installation that has the potential of property damage
due to condensate must
have a secondary drain pan installed. If
the unit is installed in a high heat and/or high humidity location,
extra insulation around the unit casing may be required. This will
prevent excessive condensate from forming on the outer surface
of the casing.
Important: Piping the condensate lines on a return side cooling
coil can be dramatically different, be sure to read info below.
