INSTALLATION
MANUAL
GENERAL
The information on the following pages is to provide the
installer the necessary information to properly install the
SpacePak EEH Series electric heaters.
The electric heaters are designed to provide heating
in a heat pump system. The model numbers, kW, and
SpacePak match-ups are shown in the Table 1 below.
See Table 1 and Figure 1 for dimensional information.
LOCATION AND MOUNTING
Before installing the heater, inspect the unit thoroughly for
shipping damage. Check all porcelain insulators for any
breaks and inspect the heater element wire to see that
none have been deformed. Check the heating elements
for loose connections that could cause overheating. If any
shipping damage is found, notify the carrier immediately.
Install the heater by attaching it directly to the air handler
using the adapter collar provided with the heater, as
shown in Figure 2.
Position the unit so the arrow label on the cover of the
electric heater control box is in the direction of the airow.

FIGURE 2: HEATER INSTALLATION
Insert the heater into the heater adapter and secure it
using the (4) #8 x ¾ modied Phillips head self drilling
screws shipped with the electric heater.
FIGURE 3
All heaters are suitable for zero clearance between
duct and combustible material. For servicing the control
box, allow enough room to swing the cover open and to
service the blower module, see Figure 4.
FIGURE 4: SERVICE CLEARANCE FOR
HORIZONTAL INSTALLATIONS (TOP VIEW)
The hinge is located on the electric heater control box
closest to the discharge end of the electric heater.
DO NOT HANG UNIT DIRECTLY
FROM HOUSING TO PREVENT DAMAGE TO THE
ELECTRICAL ELEMENTS.
Support the heater on the rafters, oor, or platform with
the air handler. If using a platform, make it large enough
to support the entire heater and air handler.

INSULATION
SPL-WG1089_A
For both vertical and horizontal installations always
allow a minimum of 18 inches (457 mm) of straight duct
between the discharge side of the electric heater and
any tee or elbow as shown in Figure 6.
FIGURE 6: LOCATION (TOP VIEW)
Note: All metal connections must be mechanically
fastened with sheet metal screws and the joints and
seams must be taped with UL- 181A-P foil faced tape or
or sealed with UL-181A-M duct mastic.
INSULATION
Insulate all metal ducting with 1.5-inch (38-mm) minimum
berglass insulation. For round duct, use either sleeve
insulation or foil-faced duct wrap. For square duct use
either berglass duct board or foil-faced duct wrap. Tape
all seams to prevent air leaks.
When the heater is installed in high humidity areas,
such as an unconditioned attic or crawlspace, there is a
possibility of condensation forming on the heater cabinet
during the cooling mode. To prevent condensation, cover
the heater with 1-inch (25-mm) foil faced berglass
insulation or duct board including the underside between
the heater and support platform. Be sure to allow access
to the control box cover for servicing. See Figure 7.
Insulate exterior cabinet, except the control panel, with a
minimum of 1.0" [25mm] thick berglass or foam rubber.
FIGURE 7
WIRING
DISCONNECT ELECTRICAL SUPPLY
BEFORE WIRING UNIT TO PREVENT INJURY OR
DEATH FROM ELECTRICAL SHOCK.
All electrical wiring must comply with all local codes and
ordinances. Use the 15 amp breaker integrated into the
heater for the air handler power supply.
Open the heater cover and connect the power supply to
terminals L1 and L2 on the high voltage terminal block.
See appropriate wiring diagram (Figures 9-14) to select
the correct wire gauge for the specic amperage of
the heater being installed. Connect a ground wire
to the ground lug labeled G. Terminals M1 and M2
on the heaters are for output power to the blower. 15
and 20kw heaters there are two breakers so you can
wire one (single) or two (dual) line input circuits. Refer
to appropriate wiring diagram (Figures 9-14) and the
label on the control box lid for specic wire sizes and
amperage.
Connect the 24V control wiring as shown in the appropriate
wiring diagram.
It is important to use a thermostat designed for use with
electric heat or two-stage heating. The internal wiring
diagrams are shown in Figures 9 through 14. The 15
and 20 kW single phase heaters contain two supply
circuits. Supply wires can be run separately for each
circuit, which is the default conguration. Using two
supply circuits allows the use of smaller gauge wires. In
some cases, it is necessary to use smaller gauge wire to
comply with building codes that limit the maximum wire
size that can be used for a single circuit.

Note: Circuit breakers installed in this device are the

a service disconnect. Circuit breakers installed within
this device DO NOT provide over current protection of
the supply wiring.
SEQUENCE OF OPERATION
All heaters have a built-in delay feature to delay the
heater from coming on before the air handler is operating.
There is no delay-off feature. As soon as the thermostat
is satised, the heater de-energizes and the air handler
will continue running for approximately 1 minute. An air
pressure switch is in series with the fan interlock relay for
added protection and safety. The heater is designed for
a softer start so that there is a short time delay between
stages.
CAPACITY AT LOWER VOLTAGES
The elements are rated at 240 Volts and should not be
used at higher voltages. Lower voltages are acceptable.
However, heaters are resistive loads so capacity is
reduced by the square of the voltage ratio.
kW (output) = kW (rated) x (V/240)
2
Therefore, multiply the rated capacity by the factor
shown in Table 3 to determine the actual output of the
heater at other voltages.

Voltage Factor

DUCT DESIGN
The design of the duct system must account for the added
restriction of the heater. Table 4 lists the static pressure
drop of the heaters. Usually it will be necessary to add
additional outlets to account for the added restriction,
particularly for the systems requiring more than 800
CFM (378 L/s). For these systems it is not unusual to
have 7 outlets per ton.
