Vert-I-Pak Installation Recommendations

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

Figure 1

VERT-I-PAK® units must be installed on an outside wall. Conned 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 oor should
be mounted at least 6" off of the ground.

below.

Figure 2

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

The above suggestions are for reference only and do not represent all possible installations. Please contact the factory for information

regarding affects of other installation arrangements.

By following these simple recommendations you can be condent that your Friedrich Vert-I-Pak® will provide years of worry-free
operation.

• 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.

Electrical Requirements

Wire Size Use O NLY wiring size recommended for single outlet branch circuit.

Fuse/Circuit Breaker

Grounding

Wire Sizing

Note: All eld wiring must comply with NEC and local codes. It is the responsibility of the installer to insure that the electrical codes are met.

Use O NLY type and size fuse or HACR circuit breaker indicated on unit's rating plate (See sample on next page). Proper current
protection to the unit is the responsibility of the owner.

Unit MUST be grounded from branch circuit to unit, or through separate ground wire provided on permanently connected units.
Be sure that branch circuit or general purpose outlet is grounded.

Use recommended wire size given in tables and install a single branch circuit. All wiring must comply with local and national
codes. NOTE: Use copper conductors only.

All 208/230v chassis must be hard wired with properly sized breaker. See nameplate for specic chassis electri­cal requirements. See gure 8 for unit wiring and wall thermostat wiring. See page 7 for wire size. Use HACR
type breakers to avoid nuisance trips. All eld wiring must be done in accordance with NEC and local codes.

CAUTION

Electric shock hazard.

Turn OFF electric power before service or installation.

All electrical connections and wiring MUST be installed by a qualied electrician and
conform to the National Electrical Code and all local codes which have jurisdiction.

Failure to do so can result in property damage, personal injury and/or death.
