CLOSET SIZING GUIDE
Since the most critical aspect of installing a GE Appliances
SPVU is the closet size, here are a few hints to prevent
installation, application and operational problems.
IMPORTANT NOTES
‘A’ dimension determined by wall thickness and plenum
size selected
‘B’ dimension minimum 4" for front installation
‘B’ dimension minimum 5" for side installation
‘C’ and ‘D’ dimensions minimum 3" for front installation
‘C’ and ‘D’ dimensions minimum 5" for side installation
‘E’ dimension minimum for 28" door - 33"
‘E’ dimension minimum for RAVRG1 Access Panel - 30"
NOTE: For easier installation and removal, door or access panel
should be centered on Zoneline.
EXTERIOR GRILLE
The architectural louver exterior grille
is mounted to the exterior flange of the
plenum and held in place with four screws
inserted from inside enclosure closet. The
grille is designed specifically for use with
the SPVU, and the use of any other grille
must be approved by GE Appliances Air
Conditioning Applications Engineering.
See grille requirements on page 42 of GE
Appliances Zoneline Architects and Engineers
manual for PTACs.
UNIT INCLUDING SLEEVE
AND FRONT PANEL
The unit is packaged with the
case and the front panel in place
(filter not included). Installation
begins by removing the front
panel and pulling the unit out
of the case. The empty case is
positioned on the platform in
the closet with the outdoor side
facing the wall plenum opening
(remove the side panel if a side installation is to be made)
and secured to the plenum with six field-supplied screws
(stainless recommended).
Level or slightly pitch the case 1/4 bubble to the outside
using the four leveling legs and, using the holes in the
bottom of the case as guides, drill holes in the mounting
platform to secure the case to the platform. Use four field-
supplied bolts, washers and nuts to secure the case to the
mounting platform. Do not tighten the bolts to the point
of distorting the case.
Failure to secure the case to the platform may result in
excessive unit vibration and increased noise level. Install
the unit into the case, either through the front or side panel
opening. With the unit in position in the case, replace the
side panel (if removed) and the front panel. Ground the unit
to the case by installing the front unit-to-case hex bolt and/
or the case-to-unit side screw (only on side installs).
The drain connection is made by connecting a 90
o
PVC
elbow to the unit’s female 3/4" NPT drain connector. The
other end of the elbow is used to run the drain to either the
internal or external drain.
The unit is shipped with a secondary drain hole. This
drain hole is shipped open and must either be plugged or
connected to an independent drain system. If a secondary
drain system is used, attach a 90° schedule 40 PVC elbow
to the secondary drain hole directed toward the secondary
drain system. If a secondary drain system is NOT used,
install a 3/4" schedule 40 PVC plug to cap the hole. Ensure
drain lines going out the plenum are sloped downward
to allow water to drain out.
A 10" diameter flange on the top of the unit is used to
connect to field-supplied, insulated, flexible or rigid
transition duct with an adjustable ring clamp.
Flexible duct may be used for transitions only. Rigid duct
must be used for 90
o
bends and tees. Do not use flexible
duct for unsupported runs of five feet or more.
