Vert-I-Pak Installation 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-PAK louver:
•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.

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.

Electrical Requirements
Wire Size |
Use ONLY wiring size recommended for single outlet branch circuit. |
|
|
|
|
Fuse/Circuit Breaker |
Use ONLY 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. |
||
|
||
Grounding |
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. |
||
|
||
Wire Sizing |
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. |
||
|
Note: All field wiring must comply with NEC and local codes. It is the responsibility of the installer to insure that the electrical codes are met.
All 208/230v chassis must be hard wired with properly sized breaker. See nameplate for specific chassis electrical requirements. See figure 8 for unit wiring and wall thermostat wiring. See page 7 for wire size. Use HACR type breakers to avoid nuisance trips. All field wiring must be done in accordance with NEC and local codes.
Electrical Rating Tables
NOTE: Use copper conductors ONLY. Wire sizes are per NEC. Check local codes for overseas applications
