WARNING
: ELECTRICAL EQUIPMENT
SHOULD BE INSTALLED BY A QUALIFIED,
LICENSED
ELECTRICIAN. IMPROPER
ELECTRICAL HOOK-UP MAY DAMAGE
EQUIPMENT, CAN CREATE A HAZARD AND WILL VOID
WARRANTY.
H. ELECTRICAL HOOKUP
The line voltage electrical service can be routed through the right
side panel or left side panel. Each area is supplied with two line
voltage knock-outs (1/2"
– 3/4" and 1" – 11/4"). Low voltage wiring
can be routed through the right or left side panel.
NOTE: When routing line voltage through the return air
compartment, conduit MUST be used (even though this is a dry
area) to comply with the NEC code. Refer to the ELECTRICAL
DATA tables for minimum wire size and maximum breaker size. All
wire sizes listed under the dual-feed circuit column are based on
no more than three (3) conductors in the same conduit. If two
circuits or more than three (3) conductors are to be routed in the
same conduit, the ampacity of the wire size listed MUST be
derated. Refer to Article 310 of the NEC code for adjustment
factors. Be sure to install a ground wire of the proper size to the
unit’s equipment ground lug.
The blower motor must be powered by 240V or 277V supply. If the
unit is supplied by 460V power, and a neutral connection is
unavailable, the motor may be powered by a 460V to 277V or
240V transformer.
I. LOW VOLTAGE WIRING
230 volt, 1- and 3-phase units are equipped with dual-primary
voltage transformers for 208/240 volt operation. These models are
factory wired to the 240 volt tap. For 208 volt operation connect the
factory-installed black wires from the 240 volt tap to the 208 volt
tap. The acceptable voltage range of the tap is as follows.
Tap Voltage Range
240 Volt 253 - 216
208 Volt 220 - 187
Six (6) conductor thermostat wires should be run from the
thermostat location to the unit. If the unit is equipped with a
powered fresh air option, seven (7) conductor thermostat wires
should be run to the unit. Thermostat wire should be sized as
shown on the table below.
Wire Gauge Maximum Length
20 45'
18 60'
16 100'
14 160'
12 250'
Refer to wiring diagrams for connection details.
HOOK-UP
STAGING OF ELECTRIC HEAT
All T Series units with electric heat assemblies above 10 kW may
be wired for single- or two-stage heat. These models come factory
wired for single-stage operation. For two-stage operation, remove
the jumper bar from between the W2 and E terminal. Wire the first-
stage heat to terminal W2. Wire the second-stage heat to terminal
E.
J. UNIT INSTALLATION
T SERIES UNITS ARE FOR USE IN SINGLE-STORY
BUILDINGS ONLY
1. As previously stated, the wall that the unit is to be installed
onto MUST be strong enough to support the unit under the
condition for which it will be used. For example, a unit to be
installed on a building that is intended to be transported will
require more wall strength than a unit installed at a
permanent site. Existing walls may need additional
reinforcement.
NEVER RELY ON EXTERIOR SIDING OR
PLYWOOD TO SUPPORT THE UNIT. Figure 2 at right
represents a typical installation of a single-story stud wall at
a permanent site. Since building materials and techniques
vary with regions and intended use, a building contractor
and/or local building code official MUST be consulted for
suitable construction methods.
2. Locate and attach the lower mounting bracket in the
desired location on the building.
3. Apply a suitable amount of caulk or silicone across the
entire length of the top rain flashing and side mounting
flanges.
4. Remove the flanges on both ends of the pallet and slide the
unit approximately 2” off the rear of pallet. Lift unit gently
into location with fork truck, taking care to align unit with
lower mounting bracket.
5. While allowing a small portion of weight on the lower
bracket, push the unit against the wall and fasten
appropriately.
K. CONDENSATE DRAIN
A
3/4” drain hose is located on the bottom side of the unit. The
drain may be extended for condensate removal to comply with
local codes (use fitting size or larger). Install a condensate trap on
this line.
SPECIAL NOTES FOR UNIT INSTALLATION
1 ) Minimum 12" clearance at the bottom of the unit for
unrestricted airflow
2) Ensure the ambient temperature uniformity around unit
3) Intake and discharge of the outdoor air flow must not be
restricted or altered
4) All insulation and sealing related to the installation must be
completed properly
M. OPTIONS
Eubank wallmount air conditioners and heat pumps have the
ability to equip a variety of options:
Electric Heat 5-20kW
Energy Recovery Ventilator
Sound Attenuation Module
Powered Ventilation Damper
Low Ambient Packages
Economizer
Lead Lag Controllers
Option kits must be installed according to the respective
installation manual to ensure safe and reliable operation.
Installation manuals are included with the option kit or can be
found on the Eubank website, www.EubankNCC.com.
5) External Static pressure should not exceed the minimum
value in the AHRI Standard 390
