Refrigerant Base Modules (RBM)
The RBM Series cooling coil comes as a module and can be
installed in the vertical or horizontal position on the return air
side of the fan coil. The RBM comes with T-mounting brackets,
thermal expansion valve, two access ports, and an external
freeze stat. This module comes heat pump ready and has most
components pre-piped. Only the two access ports and freeze
stat will need to be field installed. Fig. 01 shows an installed coil
assembly and how each piece is connected.
RBM modules can be used on any R-410A condenser if R-410A
refrigerant components are used. All Energy Saving Products
R-Series modules come standard with R-410A refrigerant
components.

Coil Configuration
The RBM module can be installed as a stand (return air base)
for the fan coil or as a side mounted coil. When the desired
air inlet side has been determined, the module can be adapted.
The module comes ready as left to up/right orientation (Fig. 02)
but can easily be changed to a right to up/left orientation. (Fig.
03) See page 3 for steps to adapt the coil to up/left.
The RBM Module can be installed in four different
configurations:
A - Entering air in through the left, leaving through the top.
B - Entering air in through the left, leaving through the right.
