#825309 - Revision A - August, 2014
Test Procedures
1. Testing Line Voltage at J-Box.
J-Box is mounted to the Support Frame on Island
Hoods and is mounted by Installer on wall behind
Upper Chimney on Wall Hoods. (See Figure 4-1)
a.
Disconnect wires between Electrical Supply and
Hood.
b.
Measure voltage from Electrical Supply L1 (typi-
cally Black) to Ground. Voltage should be 115
VAC.
c.
Measure voltage from Electrical Supply Neutral
(typically white) to ground. Voltage should be 0
VAC.
d.
Measure voltage from Electrical Supply L1 to
Neutral. Voltage should be 115 VAC.
e.
Confirm both ground screw connections are
tight.
Neutral (White)
Ground (Green)
Power Cable
L1 (Black)
3. Testing Line Voltage at 3 Pin Connector in
Electrical Box - continued
Disconnect 3 Pin Connector and test on Power
Cable Receptacle side of connector.
(See Figure 4-2)
a.
Measure voltage from Pin 1 to Pin 2. Voltage
should be 115 VAC.
b.
Measure voltage from Pin 2 to Pin 3. Voltage
should be 0 VAC.
c.
Measure voltage from Pin 1 to Pin 3. Voltage
should be 115 VAC.
2. Testing Line Voltage at the Power Cable.
Power Cable plugs into the top of the Electrical Box
on Easy Cube. (See Figure 4-1)
a.
Inside Power Cable measure voltage from L1 to
Ground. Voltage should be 115 VAC.
b.
Inside Power Cable measure voltage from
Neutral to Ground. Voltage should be 0 VAC.
c.
Inside Power Cable measure voltage from L1 to
Neutral. Voltage should be 115 VAC.
d.
Check resistance (ohms) between Ground on
Power Cable and another Ground terminal on a
near by outlet. You should read Continuity.

4. Testing Line Voltage at 7 Pin Connector on Power
Board.
On Power Board disconnect 7 Pin Connector from
Power Board. Test on Wire side of connector.
(See Figure 4-3)
a.
Measure voltage from Pin 1 to Pin 2. Voltage
should be 115 VAC.

3. Testing Line Voltage at 3 Pin Connector in
Electrical Box.
Inside Electrical Box on top of Easy Cube is a 3 pin
connector that connects the Power Cable recepta-
cle to Power Board connector.
