EXCELLENT EFFICIENCY
AND DEHUMIDIFICATION
GE Appliances recognizes the importance of energy
efficiency and dehumidification in an air conditioning
system and uses EER (Energy Efficiency Rating) as a means
of reporting the relative cooling efficiency of the unit.
EER is the cooling rating system used for single packaged
vertical air conditioners and heat pumps.
The GE Zoneline
®
single packaged vertical heat pump has
outstanding COP ratings. The measurement of the efficiency
of the heat pump output, when compared to electric
resistance heat, is called the Coefficient of Performance
(COP). This number provides a basis not only for comparing
the heat pump output to electric resistance heat, but also
the ability to directly compare heat pumps within the same
range of capacity to one another.
UNIQUE SLEEVE DESIGN
The SPVU case is installed on a field-supplied platform
and attached to the wall plenum with field-supplied screws.
See pages 8 and 15 for platform construction details.
The chassis slides into the sleeve, allowing for easy removal
of the unit for servicing and cleaning without the need to
remove condensate lines.
THREE-WAY SLIDE-OUT CHASSIS
The case is designed to allow the installation of the chassis
from the front or either side of the case. This provides
greater flexibility in building/room design and unit
placement. If access to the front of the unit is restricted by
a wall or furniture placement, the chassis can slide in from
either side of the case. If an alcove or offset is designed into
the building facade, the three-way slide-out chassis enables
the unit to be easily installed and removed for service.
ELECTRONIC TEMPERATURE LIMITING
Although the vertical unit is controlled by a wall-mounted
thermostat, there may be a need to prevent the temperature
from being set to extreme energy-wasting settings. The SPVU
has seven independent programmable heating and cooling
temperature limits. A wide selection of limits eliminates the
need to reset the limits seasonally. The temperature
limiting feature requires the use of the optional room
air temperature sensor, model RAVRMS. Designed to be
mounted on the room-side wall of the unit enclosure closet,
the room air temperature sensor allows any compatible
thermostat to be used with the unit and provide
temperature limiting.
The limits are set by dip switches located on the SPVU and
are not accessible by the room occupant. Location of the dip
switches are shown on page 14 and the temperature settings
are shown below.
COOLING TEMPERATURE LIMITS (DEGREES F.)
MIN 60° 64° 66° 68° 70° 72° 74° 76°
MAX 85° 85° 85° 85° 85° 85° 85° 85°
HEATING TEMPERATURE LIMITS (DEGREES F.)
MIN 60° 60° 60° 60° 60° 60° 60° 60°
MAX 85° 80° 78° 76° 74° 72° 70° 65°
FREEZE SENTINEL
To prevent damage to plumbing and room furnishings by
freezing temperatures, the SPVU includes Freeze Sentinel,
a feature which turns the resistance heaters on at 41° F.,
warms the indoor air to 46° F., and shuts the heater off. The
Freeze Sentinel feature requires the use of the optional room
air temperature sensor, model RAVRMS.
Designed to be mounted on the room side wall of the
unit enclosure closet, the room air temperature sensor
allows any compatible thermostat to be used with the
unit and provide Freeze Sentinel protection. Freeze
Sentinel protection is automatic with the installation
of the RAVRMS.
Even if the unit is connected to a central desk control
system or a room occupancy sensor system, and the unit
is turned off by the controlling system, Freeze Sentinel
is still active to provide protection. It may be defeated by
switching the unit’s ON/OFF switch to the OFF position,
removing the power supply to the unit or putting #2 dip
switch in DOWN position.
CONSTANT ON FAN
Some localities may require the indoor fan on single
packaged air conditioners to operate at all times, even
when the wall primary control would normally turn the
unit off. To accommodate this requirement and provide the
feature for use by anyone wanting to operate the unit in this
manner, GE Appliances has provided a switch on the SPVU
that will allow this mode of fan operation.
If the controlling dip switch (#3) is set in the UP setting,
the fan will run unless the unit’s ON/OFF switch is set to
the OFF position or power is removed from the unit.
PERMANENTLY LUBRICATED FAN MOTORS
The SPVU has two permanently lubricated, totally enclosed
fan motors. The motors are permanently lubricated to
reduce maintenance, and totally enclosed to keep dirt and
water out of the motor windings.
