Front Desk Control
Enable or disable each unit from the front desk to save energy
used to condition unoccupied rooms.
Fan Delay
Allows the evaporator blower to continue running for up to 45 sec.
after the thermostat is satisfied, maximizing cooling performance.
Random Restart
Protects against damage to electrical circuits by preventing all
units from starting at one time after power disruption. Random
restart occurs in 3 to 4 min.
Evaporator Coil Freeze Protection
Prevents ice build-up on coils and compressor damage during
the cooling mode. Attached to the coil, a temperature sensor
will de-energize the compressor when freezing conditions are
detected and re-energize the compressor when the coil warms
up again.
Ductable Return Air
Permits the connection of return air ductwork using the provid-
ed tabs (usually not required) on the inlet of the evaporator coil.
(Figure 5, pg. 9)
Note: Duct systems and registered sizes must be properly designed for
the CFM and external static pressure rating of the unit.
Adjustable Outside Air (manual)
Meets code requirements for outside air introduction. The air
vent (Figure 6, pg. 9) allows up to 50 CFM of outside air to be
introduced into the equipment closet. The air mixes with return
air entering the closet through the return air grille.
Note: Negative pressure can be introduced through an external source to
raise the 50 CFM level. Consult with the factory.

FEATURES
Compressor Restart Delay – (3 min.)
Ensures that system pressure equalizes before the system re-
starts, so compressor life is extended.
Low Ambient Lockout
Locks out compressor at 40ºF and below, thus extending com-
pressor life.
Electrical Disconnect (Factory-installed)
Makes service and maintenance easier.
Filter Brackets (Field-installed)
Installed over evaporator coil and shipped with throw-away fil-
ter (20” x 24” x 1”; see Figure 5, pg. 9).
Unique “Sleeve Drain” Condensate System
(Factory-installed) – Connects evaporator drain pan to a vertical
pipe connection in the unit’s base pan via a drain line. Evapora-
tor condensate is delivered from the unit to a catch tray in the
wall sleeve and exits the sleeve through the ¾” male NPT fitting
to allow complete piping of the drain to a condensate riser dur-
ing the rough-in stage. This eliminates condensate connection
problems when connecting the HVAC drain to the riser after the
HVAC unit is installed in the closet. Unit can be removed for
service without disconnecting the condensate piping. Additional
closet space is not needed to connect the drain.
Secondary Overflow
Should the primary condensate riser become clogged, water will
fill the catch tray and be diverted through the sleeve to the exte-
rior of the building, ensuring no leakage into the interior area.
Rain water entering the sleeve is automatically diverted to the
building exterior.

IMPORTANT:
Heat pump does not operate simultaneously with electric heat.
Electrical data in the above table only applies to units manufactured after 8/1/2000 (data code G08). Contact factory for electrical data
for units manufactured prior to 8/1/2000. Compressors in these models (after 8/1/2000) do not operate simultaneously with heater
elements. Models manufactured before 8/1/2000 (excluding the VTH24-HP) did feature simultaneous operation and therefore had higher
circuit ampacities.

One end of a 4” aluminum vent pipe is connected to the
condenser venturi and the other end is connected to the
side of the VTC/VTH cabinet. A mesh screen is installed
inside the vent pipe, and a metal plate on the side of the
cabinet covers the opening of the vent pipe. Up to 50 CFM
of outside air is introduced into the equipment closet by
removing the metal cover plate. The outside air then mixes
with the return air and is pulled through the evaporator coil
and into the supply duct.The cover plate can be re-installed
to partially close the outside air opening if less than 50 CFM
is desired. An external source of negative pressure (i.e., a
bathroom fan) could be used to introduce more than 50
CFM of outside air. Consult with factory for further details.
Note: It is suggested that a minimum 24” door be used
for access. Closet interior may be smaller than listed here
as long as the door opening allows for removing the unit.
Door opening must line up with unit to allow removal.

Instructions:
To find the minimum closet depth (dimension “C”), use
the following method:
Determine dimension “A”, which is the total finished wall
thickness.
* For 5”-8” outside wall thickness, subtract “A: from 39”
(C” = 39 - “A”)
* For 8”-12” outside wall thickness, subtract “A: from
43” (C” = 43 - “A”)
* For 12”-15” outside wall thickness, subtract “A” from

draw must be of _________ and _________ Watts at ____
_____ volts.
The EER must be a minimum of _________ EER.
Unit Chassis — Each unit must be slide-out design, ready
for installation into closet space. Unit must t into closet
space not to exceed 24” x 24” with overhead duct connec-
tions designed to .25 ESP. Unit must be tested for confor-
mance to ASTME water inltration specication ASTME
331-86, which ensures no water inltration when tested at
8" rain per hour at 63 mph wind for 15 min.
Filter — Filter provided with the unit. Installer must pro-
vide for easy accessibility.
Heat Pumps — Each unit must include a changeover ther-
mostat that senses an outside coil switch-over tempera-
ture of 25°F, lock-open refrigerant-reversing valve during
heat pump operation, temperature-activated defrost drain
and automatic emergency heat operation to override the
heat pump’s change-over thermostat and bring on electric
resistance heaters in the event of a sealed-system failure.
Compressor — The compressor must be hermetically
sealed, internally isolated, rotary-type and permanently
mounted on rubber isolators. No removal or adjustment
of compressor hold-down bolts is to be required during
installation.
Unit Controls — The unit must be controlled by a thermo-
stat. Other unit controls must include a concealed ventila-
tion control to allow the introduction of ltered air into the
room, a concealed fan mode switch to allow the owner to
preset for either continuous fan or thermostatically cycled
fan operation. Additionally, the following controls are to be
included as standard on all units:
Compressor restart delay
Random restart circuit
Front desk control
Evaporator coil freeze protection

GUIDE SPECIFICATIONS
Fan delay
Low ambient lock-out
Evaporator/Condenser Fans — Direct drive with a perma-
nent split capacitor, two-speed motor. Must have a condenser
fan and separate indoor evaporator motor. Condenser fan
must be propeller type and evaporator fan must be blower
type.
Coils — Unit’s coils must have copper tubing expanded
into rippled-edge louvered aluminum ns.
Discharge and Return Air — A unit must be able to dis-
charge air through an overhead duct system with an exter-
nal static pressure capability of 0.35" for 9,000 and 12,000
unit sizes and 0.40" for 18,000 and 24,000 unit sizes. The
return air must be capable of a free return at the unit or a
ducted return.
Warranty — Limited One-Year Warranty; Second-
through Fifth-Year Limited Replacement Compressor
Warranty
The Wall Sleeve — The wall sleeve must be of industry-ac-
cepted dimensions: from 21” [d] to 28” [d] (dependent upon
wall width, from 5”to 15”) x 22” [w] x 44” [h] and constructed
of insulated galvanized steel for corrosion resistance. Sleeve
must be shipped with weather-resistant rear closure panel
installed.
Condensate Drain — The unit must have a condensate
draining system. A vertical pipe connection in the base pan
is connected to the evaporator drain pan via a drain line.
Condensate passes from the unit to a catch tray, located in
the wall sleeve, and exits the sleeve through a ¾” male NPT
tting. (This allows piping to be done during construction
stage).
The unit must also have a secondary condensate draining
system for overow. If the primary condensate draining
system becomes clogged, water will be directed from the
catch tray, through the sleeve, to the outside of the build-
ing. Any external water source (rain, sleet, etc.) entering
the sleeve will also be diverted to the building’s exterior.
Outdoor Grilles — Must be architecturally extruded and
made of anodized aluminum (AGKV***A). All other grilles
must be submitted to our company for feasibility, airow
characteristics and compliance with U.L. regulations, where
necessary.
Hydronic Heat Units — Required for heating functions in-
