Seismic Compliance Options — Several models have
been tested and approved for installations requiring IBC or
OSHPD seismic certification. See the following tables for
approved models and options.
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

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, DA units) includes
a non-woven synthetic throwaway filter sized for low veloc-
ity and maximum efficiency. The standard option will filter
both return and outside air. For optional filters, please refer
to available option table on pages 8 and 9.
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 (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 as an option for applications
requiring higher external static capability. ECM (electroni-
cally commutated) motors are optional on all units except
42VG. 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 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.
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.
Thermostat control packages — We offer a variety of
control devices to meet the most basic to the most
demanding operating logic. All of our control schemes uti-
lize 3-speed fan control to modulate cooling output, maxi-
mize the percentage of latent heat removal, and to further
reduce the sound level when maximum cooling and
