FOR THE USER_ PERSONAL SAFETY, THIS

APPLIANCE MUST BE PROPERL Y GROUNDED

The power _rd of this appliance is quipped with

a three-_ong (grounding) p,lug_Use this with a

_ndard three-slot (grounding) wall power outlet _o,

minimize Me hazard of electric sh_k. The

custo_r should have the wall receptacle and

circuit checked by a qualified electrician to make

sure the r_:eptacle is pro_r_y groun_d.

A. S_UATIIONS WHEN THE APPLIANCE WILL

BE DI_ONNECTED _CASIONALLY:

Bec_se o_ pote_ial safety hazards, we strongly

discourage the u_ of an adapter plug. However, if

you wish to use an adapter, a TEMPORARY

CONNECTION may be made. Use UL-iisted

adapter available from most iocallhardware

stores.

The _ge slot in the adapter must be aligned with

the large slot in the receptacle to assure a p,ro_r

_larirty con_ction.

DO NOT CUT OR RE_VE' THE THIRD

USE OF EX_NSION CORD,S,

£ecause of _tentia_ sa:fe_yhazards we strongly

discourage the u_ of an e;dension cot& However,

if yo_ wish to _se an extension cord, use a CSA

ce_ified/ULqisted 3_wire (grounding) extension

cord rated at 15A, 125V.
