Building Exterior Unit Opening Requirements
VRP units must be installed on an outside wall. Confined 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 floor 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 floor 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).
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.

Preliminary Plumbing
Standard (Front Install)
The image to the right shows the installation closet for the standard (Front
Install) configuration (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.
Wall Plenum Installation
Parts included in Plenum kit:
Outside Plenum Half (Part A) Inside Plenum Half (Part B)
Field Supplied Parts:
Sealant, attachment screws, and flashing are field supplied. Silicone sealant
is recommended.
VPAWP1-8 adjusts for walls up to 4”- 8” thick.
VPAWP1-14 adjusts for walls up to 8” – 14” thick
All installations are similar.
Step 1 – Outside Wall Plenum Half
Note: The wall plenum is not designed to carry any structural load. A load bearing header must be built above the rough opening.
- Prepare the rough opening. The rough opening should be lined with metal or wood. The plenum will warp if sealed against concrete or brick.
- Dry fit the outside plenum half into the rough opening and check the fit and level.
- Remove the outside plenum half, flash the rough opening to ensure proper fit and level.
- Pre-installing the exterior louver (VPAL2) as shown above is optional (See Page 18).
- 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 2 – Inside Wall Plenum Half
- Apply sealant to all 4 flange corners and unused holes. See Detail A.
- Flash the inside of the rough opening to ensure the proper fit and level.
- Insert inside plenum half (Part B) into Outside Plenum Half (Part A). Ensure that Part A does not back out of the rough opening.
- Remove the inside plenum half.
- Apply sealant to the outside plenum half and insert into the rough opening to ensure a water-tight seal.
Step 3 – Inside Wall Plenum
Note: Do not place any screws, fasteners, or penetrating holes through the top or bottom of the plenum assembly.
- 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.
- 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.
VPDP2 Drain Kit Installation
Note: VRP07 models require installation of the VPDP2 drain kit. Please reference the VPDP2 installation manual for more detailed instructions.
- 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.
- Place the VPDP2 where the gasket has been removed as shown above.
- Ensure that the back lip of the VPDP2 is inserted no deeper than 1.5” into the exterior opening.
- Secure the VPDP2 to the finished floor or platform.
Final Drain Installation
NOTE: Failure to follow the following procedures may result in serious property damage. A field 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 flow 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.
- Ensure the drain pan is not inserted beyond 1.5 inches into the sleeve.
- Attach the drain pan to the closet floor with the appropriate field supplied hardware.
- Use the supplied drain plug to plug the unused port on the VPDP2. Proper sealant must be applied to prevent leaks.
- Use one of the first three options above for routing of the drain line.
- Check the system for leaks.
Louver Installation
Installation of the louver PRIOR to Wall Plenum Installation
- 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” flange.
- 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 floors
From the interior of the utility closet:
- Tie a rope or tether to the architectural louver and the divider in the wall plenum to prevent it from falling if dropped.
- Turn the louver sideways and push the louver out below the divider in the wall plenum.
- Pull the louver back against the wall plenum and align the holes.
- Insert and tighten all eight provided fasteners. When the louver is secured, remove the safety tether.
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.
- Loosen the two set screws located on the top side of the divider.
- Slide the top part of the divider toward the outside until the sealing strip makes contact with the exterior louver.
- Tighten the set screws to complete the adjustment.
NOTE: Let all flashing cure completely before installing the chassis.

(Front-Install Configuration)
All louver, plenum, rough plumbing, VPDP2 installation, and rough wiring steps must be complete prior to final installation of the air conditioning chassis.
Final Unit Installation Overview
Unit Final Placement – Front Install
- Ensure that power if off at the junction box feeding power to the air conditioner until all process steps are completed.
- Move the unit from the shipping base and onto the installation site.
- Insert the unit’s rear extension into the wall plenum. There should be approximately 2” of penetration of the unit into the wall plenum, resulting in a complete seal all around.
- Identify the appropriate VPDP2 drain port to use and complete plumbing.
- Attach the ductwork to the unit at the supply-air outlet and ensure the seal is air tight.
- Wire and connect the wall controller.
- Connect the main power.
Ductwork Installation
Supply air duct connection is the responsibility of the installer and should
be installed per industry best practices.
Sheet metal or duct board may be used for the transition from the discharge to
10” or larger diameter flexible ducting.
