Furnish and install air cooled through the wall package terminal air conditioners (heat
pumps). Units are rated in ac cor dance with the ARI (Air Conditioning & Refrigeration
Institute) Standards 310/380-93, CSA (Canadian Standards As so ci a tion) EEV
cer ti fi ca tion pro grams and listed by U. L. (Un der writ ers Laboratories).
Ratings
Each unit must meet the following specifi cations:
ARI rating of _________BTUH cool ing (and _________
BTUH reverse cycle heating with a COP of ________
_ at 47° F O.D.)
Electric resistance heat of _________ BTUH. Total
Amp draw must be of _________ and _________
Watts at _________ volts.
The unit must remove a minimum of _________
pints of mois ture per hour when operated at rating
con di tions. The EER must be a minimum of _______
__ EER.
Unit Chassis
Each unit must be slide out design shipped with
room cabinet front installed. Unit chassis must
have the ability to be installed with 0 clearance
from fi nished fl oor. An electrical power cord
must be included with chassis and installed by
the manufacturer to assure proper NEMA 6 or 7
confi guration and UL-approved length. Units less
than 250 volts must also have a LCDI power cord.
Unit must be tested for conformance to ASTME
water infi ltration specifi cation ASTME 331-86, which
ensures no water infi ltration when tested at 8" rain
per hour at 63 mph wind for 15 minutes.
Room Cabinet
The monochromatic front of the room cabinet
must be able to be fi eld-secured to chassis to inhibit
tampering. Filter must be accessible without removing
room front. Cabinet depth must not exceed 7⅜” to
minimize unit’s impact on room space.
Coils
Unit’s coils must have rifl ed copper tubing expanded
into rippled-edge louvered aluminum fi ns.
Heat Pumps
Each unit must include a changeover thermistor
that sens es an outside ambient switch-over
temperature as low as 24 °F, lock-open refrigerant
reversing valve dur ing heat pump op er a tion,
temperature-activated de frost drain and
au to mat ic emergency heat operation to over ride
the heat pump’s change-over thermostat and
bring on elec tric re sis tance heat ers in the event
of a sealed system failure. Unit must not operate
com pres sor and electric heaters si mul ta neous ly.
Com pres sor
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’s controls must be completely wired and
ac ces si ble from the top. Controls must include
high and low fan speeds for both cooling,
heating, fan-only op er a tion and an OFF position.
Other unit con trols must include a con cealed
ven ti la tion control to allow the introduction of
outside 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 con trols are
to be in clud ed as stan dard on all units:
• Compressor restart delay
• Random restart circuit
• Front desk control capabilities
• Automatic room freeze protection
• Remote control capability
• Electronic temperature limiter
• Remote temperature sensing capability
• Load shedding capability
Evaporator/Condenser Fans
Direct drive with a permanent, split-capacitor,
two-speed motor. Condensate must be
directed onto the bent condenser coil to aid in
evaporation and removal. Condenser fan must be
a forward-curved, 9-bladed, propeller type with
a slinger ring, and the evaporator fan must be
blower type.
Air Discharge
Must be a sloped surface so that obstructions
cannot be placed on the unit. Discharge
conditioned air can be directed into the
room at an angle of 15 or 40 degrees from the
vertical position. The discharge grille must be
of polycarbonate material to resist bend ing,
cracking, rust ing and corrosion.
Warranty
The warranty is for Full One Year on the entire unit;
Full Second through Fifth Year on the entire sealed
re frig er ant system com po nents; Limited Second
through Fifth Year on functional parts only.
