Mechanical Specifications
Controls
Unit shall be completely factory
wired with necessary controls and
contactor pressure lugs or terminal
block for power wiring. Unit shall
provide an external location for
mounting a fused disconnect device.
ReliaTel controls shall be provided
for all 24 volt control functions. The
resident control algorithms shall
make all heating, cooling, and/or
ventilating decisions in response to
electronic signals from sensors
measuring indoor and outdoor
temperatures. The control algorithm
maintains accurate temperature
control, minimizes drift from set
point, and provides better building
comfort. A centralized control shall
provide anti-short cycle timing and
time delay between compressors to
provide a higher level of machine
protection.
Defrost Controls
Adaptive demand defrost shall be
provided to permit defrost wherever
coil icing conditions begin to
significantly reduce unit capacity.
Factory Installed Options
Black Epoxy Coated Pre-Coated
Coils
The black epoxy coils have a
thermoset vinyl coating that is
bonded to the aluminum fin stock
prior to the fin-stamping process.
The pre-coated coils are an
economical option for protection in
mildly corrosive environments.
Dehumidification Option
The dehumidification (hot gas reheat)
option shall provide increased
dehumidification. The option shall
consist of a hot-gas reheat coil
located on the leaving air side of the
evaporator coil prepiped and
circuited. Low pressure switch(es)
and thermostatic expansion valve(s)
TXV are standard. Frostat™, ReliaTel
options module, and 2" pleated filters
are required but not standard. They
must be ordered and configured
separately.
High Efficiency Motors
This option is available with
efficiency ratings from 86.5 up to
91.0. It is not available for all models.
High Pressure Cutout
This option is offered for units that
do not have High Pressure cutout as
standard.
Hinged Access Doors
Sheet metal hinges are available on
the Filter, Evaporator, Fan/Motor and
the Compressor/Control Access
Doors. This option is available on all
models.
Powered or Unpowered
Convenience Outlet
This option is a GFCI, 120v/15amp, 2
plug, convenience outlet, either
powered or unpowered. When the
convenience outlet is powered, a
service receptacle disconnect will be
available. The convenience outlet is
powered from the line side of the
disconnect or circuit breaker, and
therefore will not be affected by the
position of the disconnect or circuit
breaker. This option can only be
ordered when the Through the Base
Electrical with either the Disconnect
Switch, or Circuit Breaker, option is
ordered. This option is available on
all downflow models (Gas/Electric
Only).
Stainless Steel Heat Exchanger
Gas heat exchanger shall be of drum
and tube design constructed from a
minimum 304 Grade stainless steel.
The stainless steel heat exchanger
shall have a 10-year warranty as
standard (Gas/Electric Only).
Supply and/or Return Air Smoke
Detector
With this option installed, if smoke is
detected, all unit operation will be
shut down. Reset will be manual at
the unit. Return Air Smoke Detectors
require minimum allowable airflow
when used with certain models. See
the Installation, Operation, and
Maintenance (IOM) manual for the
models affected and the minimum
allowable airflow required.
Through the Base Electrical with
Circuit Breaker
This option is a thermal magnetic,
molded case, HACR Circuit Breaker
with provisions for through the base
electrical connections. The circuit
breaker will be installed in a water
tight enclosure in the unit with
access through a swinging door.
Factory wiring will be provided from
the switch to the unit high voltage
terminal block. The circuit breaker
will provide overcurrent protection,
be sized per NEC and UL guidelines,
and be agency recognized by UL/
CSA. This option is available on all
downflow models.
Through the Base Electrical With
Disconnect Switch
Three-pole, molded case, disconnect
switch with provisions for through
the base electrical connections are
available. The disconnect switch will
be installed in the unit in a water tight
enclosure with access through a
swinging door. Factory wiring will be
provided from the switch to the unit
high voltage terminal block. The
switch will be UL/CSA agency
recognized. Note: The disconnect
switch will be sized per NEC and UL
guidelines but will not be used in
place of unit overcurrent protection.
This option is available on all
downflow models.
Through the Base Utilities Access
An electrical service entrance shall be
provided allowing electrical access
for both control and main power
connections inside the curb and
through the base of the unit. Option
will allow for field installation of
liquid-tight conduit and an external
field installed disconnect switch.
