WARNING
Installation and servicing of air conditioning equipment
can be hazardous due to internal refrigerant pressure
and live electrical components. Only trained and
qualied service personnel should install or service
this equipment. Installation and service performed by
unqualied persons can result in property damage,
personal injury or death.
Installation shall be made in accordance with the
requirements of the local utility and other authorities
having jurisdiction, or with the National Fuel Gas
Code, ANSI Z223.1 (latest edition) and the National
Electrical Code. Any alteration of internal wiring will void
certication and warranties.
CAUTION
WARNING
For your safety, do not store or use gasoline or other

General
The MagicPak All-In-One™ HVAC system model EWC
V-Series™ unit is a self-contained electric heating and
cooling unit. This unit has been examined for compliance
with Canadian Standards Association CAN/CSA-C22.2
No. 236 (latest edition) and Underwriters Laboratories
UL 1995. This unit is also in compliance with A.H.R.I.
Performance Standard 210/240. Any alterations of internal
wiring will void these listings and warranties.
Inspection
This unit is shipped in one package, completely assembled
and wired. The drain tubing is in the cooling compartment
behind the lter access panel.
If any damage is found, proper notation should be made
on the carrier’s freight bill. Damage claims should be led
with the carrier at once. Check the rating plate to conrm
heating and cooling capacities.
NOTE: Be sure to remove the chassis hold down brackets
from the outdoor side of unit before installation. These
brackets are located below the louver panels.
Location
The unit is approved for indoor installation only. It must not
be installed completely outside. Duct connections as well
as service access must be inside the building. The interior
portions of the unit may be surrounded by a closet with
clearances to combustible material held to 0” at sides, 2”
top, and 0” front and plenum. The oor may be combustible.
The grille side of the unit may be ush with, or extend
beyond, the face of the exterior wall, but should not be
recessed more than 2” from the face of the building and
should not be obstructed with trees, landscape materials,
or building structure.
If the unit is to be enclosed, provisions should be made
allowing access to the indoor side of the unit for changing
lters and for inspection. At least 29” of unobstructed space
should be provided in front of the indoor side, whether
enclosed or not, to permit removal of the cooling chassis
should repairs or inspection be required.

Installing with a Wall Sleeve
Refer to the installation instructions packed with the wall
sleeve and Figure 1 for guidance in assembly and mounting
using a wall sleeve.
• Make sure that the gaskets attached to the sleeve are
not damaged.
• Seal the space between the wall sleeve and the
building opening using non-hardening caulking
compound. This seal must be watertight.
• Assure that the unit is completely seated against the
gaskets on the wall sleeve.
• Slide the unit into the sleeve. When properly nested,
the angle on top of the unit should line up with the top
ange of the sleeve and should almost touch. Fasten
the unit to the sleeve with ve screws furnished with
the sleeve.
CAUTION
The sleeve is not intended as the sole support for the
unit. An additional support must be provided near the
return opening on the unit for adequate support. The
use of vibration isolation material between the unit and
the support is recommended.
Condensate Drain
To install the condensate line, connect one end of the
plastic tube over the 5/8” O.D. tting in the center of the
condensate pan. Connect the other end to the drain tube
running to the open trap (see Figure 2).
The drain line should pitch gradually downward at least 1”
per 10 feet of horizontal run to the open drain trap.
Be certain that the plastic drain tube has free drainage and
is not crimped or attened at any bend.
Test drainage by pouring water into the drain pan under the
evaporator and see that it is removed rapidly through the
drain tubing.
The plastic drain connection is provided so that it may
be disconnected from the permanent drain tubing in
the building without unsoldering in the event it become
necessary to remove the refrigeration chassis assembly.

Electrical Connections
All supply wiring should be done in accordance with
the National Electric Code, or with local codes, where
they prevail. Any alternation of internal wiring will void
certication and warranty.
NOTE: Units are factory wired for a 230-volt power supply.
If power supply is 208 volts, it will be necessary to change
a wire connection on unit transformer from 240V terminal
to 208V terminal as shown on the wiring diagram.
The rating plate indicates the operating voltage, phase,
ampacity, and maximum circuit protection. Minimum
operating voltage of the 208-230 volt model is 197 volts.
Units must never be installed where voltage exceeds 10%
of voltage indicated on the rating plate.
Failure of the compressor as a result of operation on
improper voltage voids the compressor replacement
warranty.

Thermostat
Install the thermostat according to directions furnished with
it. Select a location which will measure true air temperature.
The thermostat must be located on an inside wall where it
will not be aected by drafts, sunlight, or any other heat
producing appliances. Connect the wires to the terminal
block on the unit following the wiring diagram attached to
the unit.
NOTE: For EWC*30 models, a two-stage thermostat is
recommended for reaching highest eciency and full use
of two-stage compressor.
Air Filter
All indoor return air must be ltered before it passes through
the evaporator coil. A permanent-type lter is furnished
with the unit, located directly in front of evaporator coil.
Removing the front panel permits access to the lter.
A separate electric line for each circuit should be run
through a separate fused disconnect, from the main house
panel to the supply terminal block located in the unit.

The lter should be cleaned at least once during each of
the heating and cooling seasons and more frequently if
unusual dusty conditions are encountered. To clean the
