NOTES:
1. Unit weights (shown in pounds), ± 10 percent, are based on the
largest water-filled coil.
2. The operating weight information is based on 8-row water-filled
coils and double wall cabinet construction. For a different coil and
cabinet options, use the weight adjustment table (Table 1).

Step 2 — Install Mixing Box
1. Mixing boxes are pre-assembled from the factory for ease of
installation. A linkage kit consisting of two crank arms,
2 swivels, and either a 25 in. (sizes 06-16) or a 34 in. (sizes
20-30) length of 5/16 in. rod is provided for field-installation
of an actuator. Mixing boxes are only compatible with side/
bottom (horizontal units) and side/top (vertical units)
access-style filter frames (non-magnetic latching doors). See
Fig. 14 for dimensional information.
2. Assemble the base rails (provided with mixing box. (See
Fig. 8.) All hardware required for assembly is included and
the base rails are letter coded for ease of assembly. (See
Fig. 9.)

42DH- Horizontal Units
Unit is mounted flush to the outer edge of the end base rail at the
aligning unit mounting holes. (See Fig. 10.) It may be necessary to
remove factory installed sheet metal screws to enable access to all
mounting holes and to ensure proper fit. Do not remove screws
unless necessary. Secure unit to base rail using No. 8 x 1/2 in. fas
