Please read this manual thoroughly prior to equipment installation or operation. It is the installer’s responsibility to properly apply and install the equipment. Installation must be in conformance with the NFPA 70-2002National Electric Code or current edition and Universal Mechanical Code current edition and applicable local or national codes.

Proper installation is not difficult but it is essential.

Vert-I-PakInstallation Recommendations

For proper unit performance and maximum operating life please refer to the minimum installation clearances below.

Figure 1

VERT-I-PAK® units must be installed on an outside wall. Confined spaces and/or covered areas should be avoided. Units should be installed no closer than 12" apart when two units are side by side. If three of more units are to operate next to one another allow a minimum of 60" between units or pairs of units. Also, a vertical clearance of 60" should be maintained between units. Units installed on the bottom floor should be mounted at least 6" off of the ground.

Figure 2

Any time obstructions are present use the following guidelines for proper spacing from the VERT-I-PAKlouver:

For minor obstructions such as lamp poles or small shrubbery a clearance of 24" from the outdoor louver should be maintained.

For major obstructions such as a solid fence, wall or other heat rejecting device like a condensing unit, a minimum distance of 72" should be kept.

A. Install the wall plenum (VPAWP1-8/1-14)components in accordance with the installation instructions provided with each accessory.

IMPORTANT REMINDER: FRIEDRICH WALL PLENUM IS NOT DESIGNED TO CARRY STRUCTURAL LOADS. PROPER WALL HEADER CONSTRUCTION IS REQUIRED. THE PLENUM REQUIRES PROPER FLASHING, SHIM AND CAULK FOR A WEATHER RESISTANT INSTALLATION.

B. Ensure that the divider is adjusted properly for the depth of the wall in accordance with the accessory installation manual.

Important: all 208/230v chassis must be hard wired with properly sized breaker. See nameplate for specific chassis electrical requirements. See page 8 - Figure 5 for unit wiring and wall thermostat wiring. See page 8 for wire size. Use HACR type breakers to avoid nuisance trips. All field wiring must be done in accordance with nec and local codes.

Must have a minumum of 220 square inches of free area.

All Vert-I-Pakchassis are shipped with a 14 x 20 filter installed. If an accessory filter holder is to be used, you MUST remove the factory shipped filter from the chassis. Do NOT use two filters

Notes:

A.These are the Friedrich recommended return air grille / filter / access panel arrangements. Consult the factory on other arrangements. Improper return air arrangements will cause performance problems.

B.Return air arrangements are shown from the front, but can also be installed from the right or left side of the unit.
