Module RPM Refrigerant Module Installation (RPM-E) (1/4)
Refrigerant Modules (rpm-e)
The RPM-E series cooling module can be used with the
Hi-Velocity Fancoil, installed in many different positions. It
is pre-piped with an adjustable, heat pump ready, thermal
expansion valve and comes with a bleed port, sight glass,
suction and liquid line access ports, freeze-stat, and two L
brackets for mounting.
The RPM-E comes as a complete module and must be
installed in the vertical position on the return air side of
the fancoil; the unit cannot be turned on its side and is a
draw through unit only. The module offers multi-position
airflow configurations for horizontal, highboy, or counter-
flow configurations.
(Fig. 01)
The TXV (Thermal Expansion Valve), sight glass,
access ports, and freeze-stat are already installed
and are accessible through an easy to remove access
hatch. The liquid and suction lines have male solder
connections at a standard width making connections to
the condenser lines quick and easy.
Fig. 01 - RPM-E Cooling Module
When installing, any combination of A to B or B to A
can be used. For example, a horizontal application could
use A to B while highboy applications could use A to B1.
Do not use a combination of A to A1 or B to B1, as this
would bypass the cooling coil completely. The knock-
outs can be removed with a screw driver and hammer.
Ensure caution is used when opening the knock-outs,
as any extreme protrusion into the module may damage
the coil surface.
Configurations
Two L mounting brackets are shipped loose for
attaching the RPM-E to the fancoil, along with two
sided foam tape for an air seal between the units. When
mounting the cooling coil to the fancoil
(Fig. 02)
, 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.
