STEP 4: DOUBLE CHECK the electrical connections to make sure they are correct and that all wire
connections are tight and secure. Also confirm that the correct breaker size and wire gauge has been
used and confirm that the unit has been connected to a ground in accordance with applicable codes.
STEP 5: Confirm that all air has been purged from the water lines prior to turning on power to the unit.
CAUTION: Ensure that you have made the correct connections. You must follow the wire connection
as shown to ensure proper operation of the unit. If you mix up one set of wires with another, the unit
will not operate correctly even though it turns on and otherwise appears to function properly.
The water heater is now installed and ready to use! Follow the General Operating Instructions to
complete the setup. We highly recommend that this is done with the homeowner present.
Notes:
1. All electrical work must comply with national and applicable state and local electrical codes.
2. This water heater must be permanently connected to the direct main breaker panel. The use of a
plug and socket is forbidden.
3. The unit must be connected to a properly grounded dedicated branch circuit of proper voltage rating.
4. The EVT-9K hot water unit needs a 40AMP double pole breaker and a set of 8AWG/2 wires with
240V Grounding wire for proper power supply.
5. Before beginning any work on the electric connections, make sure that the main breaker panel
switch is OFF to avoid any danger of electric shock.
6. All mounting and plumbing must be completed before proceeding with electrical hook-up.
7. While connecting the wires to the terminal blocks, please make sure the metal wire ends and the
terminal blocks touch completely. Then tighten the screws to make sure the full current can go
through.
8. Connect the wires to Terminal Block and fully tighten them as follow:
• Connect live wire (Black) L1 to the terminal block L1 on the water heater.
• Connect live wire (Red) L2 to the terminal block L2 on the water heater.
• Connect copper Grounding wire to the Grounding terminal block on the water heater.
