STANDARD SIZE AIR FILTER
A number of filters, providing varying degrees of filtering
efficiency, are available on the market today. GE Appliances
has designed the SPVU to accommodate a number of filter
placement options. All of the options designed for the unit
use a standard size 20" W x 20" H x 1" D filter. Since the
filter is field supplied, GE Appliances has allowed the owner
or property manager to decide which type of filter to use
with the unit.
A different size filter may also be used in a field-supplied
frame installed in a return air grille mounted in the closet
enclosure door or wall. If a different size filter is used,
it must be at least 20" W x 20" H x 1" D and provide
no more restriction to air flow than the standard
20"W x 20"H x 1"D filter.
The unit must not be operated without a filter in place,
even during construction.
GE Appliances provides three filter placement options
for design and installation flexibility. A filter bracket is
provided in the front panel of the Zoneline vertical unit case,
which allows the use of a louvered closet door. The bracket is
mounted to allow the filter to be inserted from
the top of the bracket rather than sliding in from the side,
where the enclosure wall may interfere with filter removal.
An access panel, accessory model number RAVRG1, for the
closet enclosure is the second filter placement option. The
access panel requires a 28" W x 48" H cutout in the unit
closet enclosure wall and provides access to the unit for
servicing and removal. The access panel should be located
in the wall such that the centerline of the access panel
matches the centerline of the case to allow for removal of the
chassis. The bottom of the access panel should be at least 1"
below the unit support platform to allow for easy removal of
the Zoneline Vertical Unit.
The third filter placement option provided by GE Appliances
is incorporated in a return air grille, accessory model
number RAVRG2, designed to be mounted in a flat closet
access door. The door must have a minimum clear opening
of 24" to allow for installation and removal of the unit.
GE Appliances recommends a 28" wide door. A 20-3/8" W
x 20 3/8" H cutout is required in the door to accommodate
the grille and filter bracket.
Only one filter is to be used in the installation. Multiple
filters will reduce the air flow and affect unit performance.
A clean filter is essential to efficient unit operation.
The filter should be checked at least every 30 days and
replaced if dirty.
CENTRAL DESK CONTROL (CDC)
Terminals are provided on the unit to allow a central desk
control system to be interfaced with the unit. The most
common installation of this type of system is a switch
mounted at the registration desk; and, upon guest check-in,
the switch is activated to allow the air conditioner to operate.
Likewise, when the guest checks out, the device is switched
to the “OFF” setting so the unit will not operate when
the room is not rented. In some resort areas, devices are
connected to sliding glass doors, and opening the doors
causes a contact to close, turning the air conditioner off.
This prevents the unit from running and wasting energy
with the sliding glass door open.
IMPORTANT CDC NOTES:
1. The unit requires the use of a normally open switch.
Closing the circuit interrupts power to the unit.
2. Both wires comprising the circuit must connect to the
CDC terminals on the unit and to the controlling switch.
Do not use a common buss (at the unit or at the switch
panel) in the wiring.
3. A 24-volt transformer is contained within the Zoneline
Ver tica l Un it. No external voltage may be applied to the
unit through the CDC terminals.
4. Minimum wire size for CDC wiring:
WIRE SIZE # AWG MAXIMUM ALLOWABLE LENGTH
#22 600 Ft.
#20 900 Ft.
#18 1,500 Ft.
#16 2,000 Ft.
OCCUPANCY SENSOR INTERFACE
The SPVU is equipped with a terminal connection to allow
it to interface with a field-supplied motion sensor and a
door sensor to allow a room occupancy detection system to
be connected to the unit. Various companies market and
install room occupancy systems as a means of reducing the
operating cost of the unit. GE Appliances does not market
or install these systems, but provides the interface terminals
on the unit and logic within the microprocessor controls to
permit these systems to be installed at a minimum cost to
the property owner.
HIGH AND LOW FAN SPEEDS
If the SPVU is connected to a wall thermostat without
the ability to provide two fan speeds, the fan speed will
be determined by connecting the wire controlling the fan
to either the low speed fan terminal or the high speed fan
terminal on the unit.
