WARNING! 

ALL ELECTRICAL WIRING OF THIS COMPRESSOR MUST BE DONE BY 

A QUALIFIED ELECTRICIAN.  

FAILURE TO COMPLY MAY RESULT IN SERIOUS INJURY! ALL      

ADJUSTMENTS OR REPAIRS MUST BE DONE WITH THE ELECTRICAL 

PANEL CIRCUIT BREAKER IN THE OFF POSITION (IF HARD WIRED) OR 

WITH THE POWER CORD DISCONNECTED (IF POWER CORD IS 

INSTALLED) FROM THE POWER SOURCE. FAILURE TO COMPLY MAY 

RESULT IN SERIOUS INJURY!

ELECTRICAL INFORMATION

ELECTRICAL INSTALLATION 

 

Hard Wiring from Electrical Source 

 
This compressor does not have a factory installed power cord, normally      
stationary compressors are permanently hard wired directly from the        
electrical source to the magnetic switch (A) Fig.1 by a qualified electrician. 
This compressor must be grounded, the green conductor of the cord used 
must be connected to the grounding screw inside the magnetic switch. See 
grounding information below. 
 

Warning!

 Do not attempt to hard wire this compressor yourself unless you 

are a qualified electrician. Overheating, short circuiting and fire damage will 
result from inadequate wiring. 
 
Electrical wiring codes, local or provincial may differ from area to area. 
Source wiring, plug and protector must be rated for at least the amperage 
and voltage indicated on the main technical nameplate. Use a slow blow 
fuse type D or a circuit breaker. 
 

Installing 240V Power Cord 

 
A properly sized 240V 3 wire power cord (2 lines, 1 ground) having a ground 
conductor and plug may also be installed to the magnetic switch, the green 
conductor must be connected to the grounding screw in the magnetic 
switch. It is recommended to have the power cord installed by a qualified 
electrician. Refer to Fig.2 for power cord wiring diagram. 
 

GROUNDING 

 
This compressor must be grounded. If it should malfunction or breakdown, 
grounding provides a path of least resistance for electric current, to reduce 
the risk of electric shock.  
 

WARNING:

 IF NOT PROPERLY GROUNDED, THIS MACHINE CAN 

CAUSE ELECTRICAL SHOCK, PARTICULARLY WHEN OPERATED IN 
DAMP LOCATIONS. TO AVOID SHOCK OR FIRE, IF THE CORD IS WORN 
OR DAMAGED IN ANY WAY, HAVE IT REPLACED IMMEDIATELY.
