Vert-I-Pak Required Minimum Clearances Building Exterior Unit Opening Requirements VPAK 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).

Wall Opening Dimensions Exterior Wall Plenum Cut-Out Dimensions (W x H): 24 5/8” x 30 7/8” 3/4” NOTE: The distance between the rough opening and the finished floor/platform must be 3/4”. If the installation will utilize an auxiliary drain pan it may not exceed 3/4” in height.
Wall Plenum Installation Parts included in Plenum kit: B Outside Plenum Half (Part A) Inside Plenum Half (Part B) A Field Supplied Parts: Sealant, attachment screws, and flashing are field supplied. Silicone sealant is recommended. Flashing Sealant VPAWP-8 adjust for walls up to 4”- 8” thick. VPAWP-14 adjust for walls up to 8” - 14” thick Shim All installations are similar.
Wall Plenum Installation 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. 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 fit the outside plenum half into the rough opening and check the fit and level. 3.
Wall Plenum Installation Step 2 - Inside Wall Plenum Half Caulk all 8 Flange Corners and Unused Holes Detail A 1. Apply sealant to all 4 flange corners and unused holes. See Detail A. 2. Flash the inside of the rough opening to ensure the proper fit and level. 3. Insert inside plenum half (Part B) into outside plenum half (Part A). Ensure that Part A does not back out of the rough opening. 4. Remove the inside plenum half. 5.
Wall Plenum Installation Step 3 - Inside Wall Plenum (cont.) B Detail B 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.
Louver Installation Installation of the louver PRIOR to wall plenum installation 1. 2. 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: 1.
Final Wall Plenum and Architectural Louver Installation Louver 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.
Chassis Installation A 1. Ensure that the wall plenum and louver are installed in accordance with the instructions listed on pages 13-18. 2. Place the chassis into the closet with the outdoor side facing the wall plenum opening. 3. Slide the chassis into the wall plenum until the plenum divider seal is established. NOTE: The Vert-I-Pak chassis must be inserted into the wall plenum so that the plenum divider gasket makes contact with the plastic condenser baffle on the unit.
Primary Drain Installation Nipple 3/4” PVC/NPT Union 3/4” FTP/SLIP Supplied 3/4” plugs Threaded end Example of field supplied DWV system Slip end NOTE: Failure to follow the following procedures may result in serious property damage. A field supplied secondary condensate pan or P-trap 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.
Indoor Return Air Grille and Ductwork Installation Option 1 Option 2 VPRG4/R Return Air Grille with Access Panel A field-supplied (25” x 20”) can be mounted inside the hinged access door. The door can be installed with the grille oriented at the top of the panel for improved sound attenuation. Field Supplied Return Air Grille A field supplied return air grille divorced from the access panel must have a minimum 250 square inches of free area.
Remote Thermostat and Low Voltage Control Connection Remote Thermostat Auxiliary Fan Control All Friedrich Vert-I-Pak units are factory configured to be controlled by using a single stage heat/cool remote wall mounted thermostat. The thermostat may be auto or manual changeover as long as the control configuration matches that of the Vert-I-Pak unit. The Friedrich Vert-I-Pak also has the ability to control a 24VAC relay to activate an auxiliary or transfer fan.

Service & Warranty Servicing / Chassis Quick Change Outs The chassis is designed for quick disconnect and change out. For minor electrical service, the control box cover lifts straight up after the screws and disconnect pull-out are removed. For major electrical,refrigeration, and fan service the chassis should be removed from the utility closet. Electrical Shock Hazard Pull out electrical disconnect on front of the chassis and turn off all power to unit before servicing.
Diagnostic Error Codes Unit Control Panel The display has four (4) digits. The left two digits indicate the error code (1-24) and the “On/Off” icons above these digits indicate the current state of the error code. The right two digits show the history count (up to 99) of the associated error. The display contains a maintenance icon (wrench) that will illuminate when the unit requires maintenance.
