Condensate overflow switch — This switch shuts down
the unit when the water level in the drain pan reaches an
unsafe level. Building code changes in many locales now
require this type of device.
Decorative colors — A wide variety of colors (Cham-
pagne Beige, Toffee Brown, Ermine Grey, and Polar
White) are available to match any interior décor. Select a
desired color from a paint chip chart, Catalog number
842-011, or provide paint chip for matching. Standard
color is now Arctic White; the other colors require a special
quote. Optional or custom colors will only be quoted by the
factory if the volume is significant enough to use the mini-
mum quantity of paint required by the painting vendor.
Therefore, the optional or custom color will not be avail-
able on small quantities of units. As an alternative, units
can be coated with primer by the factory to allow for field
painting. Decorative colors may be applied to:
• Cabinet of 42VB, VF, VE, VG
• Cabinet of 42CG
• Panels of 42SH

Electric heaters — Coils are of high grade single-phase,
nichrome resistance wire, insulated by ceramic insulators in
plated steel brackets. Heater sizes available are shown in
the application data section for the respective units. Not
available on 42VG units.
Filters — Each unit (except the 42CA, CH, DA units)
includes a non-woven synthetic throwaway filter sized for
low velocity and maximum efficiency. The standard option
will filter both return and outside air. Optional permanent
aluminum filters with cleanable, non-aluminum filter media
are available for all 42C Series except 42CA, CH; 42DC,
DD, DE; all 42V Series except 42VG; and all 42S Series
except 42SU, SM units.
Fusing — Incoming power fusing, as well as blower motor
and control sub-fusing for units that use electric heat. The
blower motor and control sub-fusing is available (single
power source wiring) is required when single source power
with electric heat is specified.
Manual air vents — Each standard coil includes a man-
ual air vent to allow venting at the coil if necessary for
quick, complete air elimination.
Motors — Three-speed PSC (permanent split capacitor)
motors are offered as standard, providing the ability to
adjust airflow to meet varying load conditions. High static
PSC motors are available with a special quote for applica-
tions requiring higher external static capability. ECM (elec-
tronically commutated) motors are optional on 42SM and
42SU, and are available with a special quote on all other
models. ECM motors offer programmable features, low
sound, and increased energy efficiency. Refer to the appli-
cation data section for more information on ECM control
methods.
Outside-air opening/damper — Damper is adjustable
from 0 to 25% and provides ventilation air to unit.
(Manual/motorized damper available on 42VA, VB, VF
and 42SG, SH, SJ, SM units.)
Service switches — Concealed service switches are
available for use by maintenance and service personnel to
shut off the power while working on the unit.
Single power source connection — Factory-installed
junction box allows use of single power source for motor
and heater when they are of the same voltage.
Stainless steel construction options — On the 42VA,
VB and VF units, stainless steel outer cabinets and stainless
steel internal chassis are available. Stainless steel's proper-
ties of corrosion and impact resistance make this option
ideal for damp, humid environments like locker rooms,
restrooms, dormitory rooms, corrosive work areas, kitch-
ens, food processing areas, etc. Its high-end appearance
makes the option ideal for upscale applications.
Stamped toe space return-air grille — The return-air
grille is available as a factory-installed option for 42VB and
42VF units.
Tamperproof Camloc fasteners (Allen head) —
Camloc fasteners are installed on the access panels and are
available for all cabinet model units.
