POWER CONNECTION KIT
The SPVUs have a universal heater assembly that is
capable of producing electric resistance heat that can
operate on a 15-amp, 20-amp, or 30-amp circuit. The
amount of resistance heat is determined by the selection
of the correct power connection kit. This is the same
type of connection used by GE Appliances for years
in the Zoneline
®
units.
Units installed on 230- or 208-volt circuits may be line cord
connected (by plugging the line cord into a wall-mounted
receptacle in the enclosure closet) or directly connected.
All SPVUs come with a unit-mounted junction box to
contain the wiring connections if a direct connection
installation is required. The same power connection
kit is used for line-cord connection or to make a direct
connection. Instructions for making a direct connection
on 230- or 208-volt circuits are included in the unit
installation instructions.
Units installed on a 265-volt circuit must be direct
connected in accordance with National Electrical Code.
All SPVUs come with a unit mounted junction box to
contain the wiring connections when direct connection
installation is made. For more information, see Power
Connection kits on page 11.
RETURN AIR GRILLE,
ACCESS PANEL OR
LOUVERED CLOSET DOOR
The return air from the room to the unit
may enter the enclosure closet through
one of four ways. A louvered door may be
installed on the closet to allow return air
to enter. When a louvered door is used,
the filter would be installed in the filter
bracket on the front panel of the unit.
A wall-mounted access panel may be used instead of
a louvered door. The return air is through the access
panel, model RAVRG1, which requires a 28" W x 48" H
cutout in the wall, and there is a filter bracket behind
the grille louvers.
A return air grille, model RAVRG2, may also be used and
is designed to be installed in a 20-3/8" by 20-3/8" cutout
in a flush closet door. In this installation, a filter can fit
into the bracket in the RAVRG2.
A field-supplied return air grille, with a minimum dimension
of 20"W x 20"H, may be used if mounted in a cutout in the
door or wall. When employing this method for return air,
the filter is installed in the bracket mounted on the unit.
REMOTE THERMOSTAT
The
SPVU
s are controlled by a wall-
mounted thermostat. GE Appliances
offers a complete line of thermostats
to interface with the units, or most
24-VAC thermostats may be used. If
a non-GE Appliances thermostat is used, the compatibility of
the thermostat with the unit is the responsibility of the installer.
The unit has an integral transformer, and no external voltage or
transformer may be used.
One of the customer-requested features on the
SPVU
is the
ability for the user to select either HIGH or LOW fan speed
operation at the thermostat. See information on page 6.
Maximum wiring length and wire size: AWG 18 up to 66 feet -
AWG 20 up to 66 feet; AWG 24 up to 40 feet.
STANDARD SIZE FILTER - FIELD SUPPLIED
The
SPVU
uses a standard size 20"W x 20"H x 1"D air
conditioner/furnace filter. The filter is not provided with
the unit, but can be purchased at any building supply or
maintenance equipment supplier. The standard size filter
allows the use of special filters if the owner desires. Regardless
of the installation and the return air method, only one filter may
be used in the installation.
OPTIONAL: ROOM AIR TEMPERATURE
SENSOR - RAVRMS
The Room Air Temperature Sensor accessory, model number
RAVRMS, is available as an option to allow Temperature
Limiting and Freeze Sentinel protection. The Room Air
Temperature Sensor has a nine-foot wiring harness designed
to allow the sensor to mount on the room side of the closet
wall. Terminal connectors are located on the terminal block
inside the unit to permit easy connection of the Room Air
Temperature Sensor conductors.
