YHave only qualified persons make this installation.

YDisconnect and lockout/tag- out input power before con- necting input conductors for wall receptacle or from unit.

YSpecial installation may be required where gasoline or volatile liquids are present – see NEC Article 511 or CEC Section 20.

230 Volt Models:

Units come equipped with input power cord and plug. Wall recep- tacle is customer supplied. To install, select type and size input and grounding conductors using Section 4-4. Conductor rating must comply with national, state, and local electrical codes.

Install and connect grounding con- ductor and input conductors in con- duit or equivalent between wall receptacle and deenergized line disconnect device.

All Other Models:

Units come equipped with input power cord for installation into line disconnect device. Select type and size overcurrent protection using Section 4-4.
