Refrigerant Modules (RCM-I)
The RCM-I cooling coil comes as a module and must be
installed in the horizontal position on the return air side of the
fan coil. RCM-I modules come with two L mounting brackets,
two access ports, carry-over screen and additional components
for air sealing.

Access Ports
When refrigerant lines are connected to the RCM-I coil, high
and low side access ports must be connected as well. (Fig. 01 -
reference 2 & 6) With the use of a tee and reducer this process is
simplified. The access ports are required for system startup and
for future trouble shooting or service. When reading refrigerant
pressures/temperatures, always read them at the evaporator
access ports.
RCM-I 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.
This module is for use with HVS-36 and HVS-60 Inverter
Heat Pump Condensing Units. It does not come with thermal
expansion valve, as there are internal EXVs inside the Heat
Pump. When installing the RCM-I Modules,
DO NOT INSTALL
WITH TXVs.
The module will come with access ports that will need to
be installed to read refrigerant pressures/temperatures at the
Evaporator (RCM-I). Fig. 01 shows approximate installation
locations for these components.
RCM-I Modules were designed to be used with the HVS-
36 and HVS-60 Heat Pumps but can be used on any R-410A
Condensing Unit, as long as a TXV is installed as well. All Energy
Saving Products cooling modules come standard with R-410A
refrigerant components.

Mounting Brackets
Mounting the cooling coil to the fan coil can be done with
the L brackets supplied (Fig. 02), ensure that no screws puncture
the drain pan or coil. Page 8 has the dimensions of the cooling
modules.
