Electrical Connection; Remove Front Cover; Using A Voltmeter - EcoSmart ECO 8 Troubleshooting Manual

Activity C | Electrical Connection
Models 8-13 kW are supplied with a 2-prong terminal block (part number 6, on page 3). Each one
of the connection sets must be connected to an independent double pole breaker.
 8 kW requires 1 double pole 40 amp breaker
 11-13 kW requires 1 double pole 60 amp breaker
Check that the set of wires from each leg are connected correctly, otherwise the unit will not
function as designed. To make sure wiring is connected correctly, perform the following test.

1. Remove front cover

a. Locate 2 small Phillips head screws on bottom of unit
b. Unscrew front cover of unit. You will notice a "Warranty Void if Seal Broken";
disregard this.
i. Warranty will not be voided. This sticker is there for safety purposes to

2. Using a voltmeter

a. Place one probe on black wire terminal and the other probe on red wire terminal,
when measuring across you should get a reading of 208-240v (depending on the
power coming from your service panel).
b. If you are getting a 0.00, or low voltage reading. The problem might not be at the
unit, but at your electrical panel, or breakers. Please check power at panel or
directly at breaker.
Keep in mind the voltage you are receiving at the terminal will depend how many kilowatts (kW)
your unit can pull. If you are receiving power lower than 220v, your unit decreases in kW by 25%
giving you a lower temperature rise. For example: an 11 kW model receiving power lower than
220 volts will become an 8.25 kW model.
