VRP®Required Minimum Clearances
Grill Clearance Requirements
Where obstructions are present use the
following guidelines for proper spacing from
the VRP exterior louvered grill. Friedrich
recommends that ALL obstructions are a
minimum of 72” from the exhaust.
For minor obstruction(s) such as lamp poles
or small shrubbery, a clearance of 24” from
the outdoor louver must be maintained.
For major obstructions such as a solid
fence, wall, or other heat rejecting devices
like a condensing unit, a minimum distance
of 72” must be kept.
The the example pictured above is for reference only and does not represent all possible installations. Please contact Friedrich
Air Conditioning for information regarding effects of other installation arrangements.
Building Exterior Unit Opening Requirements
VRP units must be installed on an outside wall. Conned spaces and/or covered areas should be avoided. Units must
be installed no closer than 12” apart when two units are side by side. If three or more units are to operate next to one
another, maintain a minimum of 60” between units or pairs of units (Figure B). If more than two units are sharing a oor
with adjacent, outset units, a minimum distance of 64” must be kept between units (Figure C). Also, a vertical clearance of
60” must be maintained (Figure A) between units. Units installed on the bottom oor must be mounted at least 6” off of the
ground. If two units are facing each other, a minimum distance of 108” must be kept between units (Figure D).

Preliminary Plumbing
Standard (Front Install)
The image to the right shows the installation
closet for the standard (Front Install) conguration
(where the wall plenum is opposite the service
access door).
A drainage system is required, and should provide
a “P-trap” to prevent undesirable waste gas
from entering into the residential area. This is
represented by a vertical standpipe in the image
shown (Detail A), but other solutions are possible
and are at the discretion of the building designer
and contractor.
The near wall has been trimmed away at the door
centerline to permit full view of the installation.

Note: The wall plenum is not designed to carry any structural load. A load bearing header must be built above
the rough opening.
1) Prepare the rough opening. The rough opening should be lined with metal or wood. The plenum will warp if
sealed against concrete or brick.
2) Dry t the outside plenum half into the rough opening and check the t and level.
3) Remove the outside plenum half, ash the rough opening to ensure proper t and level.
4) Pre-installing the exterior louver (VPAL2) as shown above is optional (See Page 18).
5) Apply sealant to the outside plenum half and insert into the rough opening to ensure a water-tight seal.
Ensure that the oustide plenum half is securely attached to the framed opening.

Step 3 - Inside Wall Plenum (cont.)
Note: Do not place any screws, fasteners, or penetrating holes through the top or bottom of the plenum
assembly.
1) Drill pilot holes on the interior of the inside plenum half (Part B) as show in Detail B. Pilot holes should be
located approximately 4” from the top and bottom of the inside plenum half, on both the left and right sides.
2) Install fasteners through each pilot hole. Fastener must pass through both Part A and Part B. If the inside
and outside plenum halves do not overlap at fastening point, be certain to drill extra holes where needed to
secure both Part A and Part B to the rough opening.

17
VPDP2 Drain Kit Installation
Note: VRP07 models require installation of the VPDP2 drain kit. Please reference the VPDP2 installation
manual for more detailed instructions.
1) Cut away gasket from the of the base of the inside wall plenum half the length of the drain kit beginning
from the bottom right corner.
2) Place the VPDP2 where the gasket has been removed as shown above.
3) Ensure that the back lip of the VPDP2 is inserted no deeper than 1.5” into the exterior opening.
4) Secure the VPDP2 to the nished oor or platform.

18
Final Drain Installation
NOTE: Failure to follow the following procedures may result in serious property damage. A eld supplied secondary
condensate pan may be required. Check with local codes. In case of drainage system blockage, the unit base will allow
excess water to ow out of the unit through the plenum and the architectural louver. It is critical to ensure that the
drainage path is not blocked or obstructed in any way during installation.
1) Ensure the drain pan is not inserted beyond 1.5 inches into the sleeve.
2) Attach the drain pan to the closet oor with the appropriate eld supplied hardware.
3) Use the supplied drain plug to plug the unused port on the VPDP2. Proper sealant must be applied to prevent
leaks.
4) Use one of the rst three options above for routing of the drain line.
5) Check the system for leaks.
Option 1
Run condensate line

Installation of the louver PRIOR to Wall Plenum Installation
1) Hold the louver up to the outside plenum half (Part A) and line up the louver top with the very top edge of the
¾” ange.
2) Line up the wall plenum holes with the threaded holes in the louver and securely tighten fasteners.
Installation of the louver AFTER the installation of wall plenum on
elevated oors
From the interior of the utility closet:
1) Tie a rope or tether to the architectural louver and the divider in
the wall plenum to prevent it from falling if dropped.
3) Turn the louver sideways and push the louver out below the
divider in the wall plenum.
4) Pull the louver back against the wall plenum and align the holes.
5) Insert and tighten all eight provided fasteners. When the louver
is secured, remove the safety tether.

20
Final Wall Plenum and Architectural Louver Installation
NOTE: Ensure that the weather strip is undamaged and provides a continuous
seal around the inner perimeter of the plenum.
Apply silicone grease or other non-petroleum-based lubricants to the weather strip to enhance the sealing
capability of the weather strip and ease installation of the air conditioner chassis.
1) Loosen the two set screws located on the top side of the divider.
2) Slide the top part of the divider toward the outside until the sealing strip makes contact with the exterior
louver.
3) Tighten the set screws to complete the adjustment.
