If there is never a risk of condensation, meaning the ambient room temperature is above the combustion air dew point at all
times, the complete dehumidification system is not needed. This means adding the additional SV2 Series Heat Exchanger kit is
then not needed.
For detailed mounting and application information for the heat exchanger, refer to the
Outdoor Air Installations
section of this
manual and

Description
HEATEXCHANGER-000
Heat exchanger kit for premix applications. Includes heat exchanger, 3 pulse line insulation
sleeves (1 m/39.4 in each), sealing nut + washer for mounting to V2MU mixing unit, (4) M4X54
screws, FARMOD insulating shoe and (4) 4.3x8x11 spacers.
Table 21. Heat exchanger Information.
NOTE: The fittings and tubing to connect the Heat Exchanger to the FARMOD are sold separately in kits. Tubing is
available in aluminum or plastic. Fittings are available for connection to the aluminum or plastic tubing in straight,
tee and 90 degree configurations. Refer to
Table 17
for information.

Air Pre-Filter
The air pre-filter is included with every premix valve and is available as a field replacement part as well. The air pre-filter MUST
be installed in every premix system, regardless of whether the Heat Exchanger is used. The filter is designed to remove fine dust
particles from the air stream to the valve FARMOD, which can affect the flow resistance to the internal sensors and eventually
cause nuisance lockouts.
The filter must be mounted between the V2MU mixing unit and the valve FARMOD in the air pulse line. If the Heat Exchanger
is used, it must also be mounted between the V2MU mixing unit and the valve FARMOD, with the Heat Exchanger first and the
filter second. Refer to
Fig. 45, Fig. 46 and Fig. 47
for mounting orientations.
