5- ELECTRICAL INSTALLATION
Eemax recommends that this product be installed by a licensed and qualified electrician in accordance with all
applicable national, state, provincial, and local electrical codes. As with all electrical appliances, under no
circumstances should you attempt to install, repair or disassemble this water heater without first shutting off all
power to the unit directly at the fuse or breaker box. Make sure to shut off all breakers. SERIOUS BODILY INJURY OR
DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.
All wiring (wire gauge) and circuit protection (breakers) must comply with the U.S. National Electrical Code (NEC)
in the U.S.A., or the Canadian Electrical Code (CEC) in Canada. Failure to do so could result in property damage
and/or personal injury, and void your warranty. Note: the Canadian Electrical Code generally requires that all
supply wires and corresponding circuit protection used for domestic hot water heating and hydronic heating
applications be sized to a minimum of 125% of the maximum current rating of the heater (see model specifications
below for details).
Before installing this product, ensure that the home has sufficient electrical power available to handle the
maximum amperage load of the applicable model.
IMPORTANT NOTES:
Model EEM24008, EEM24011, and EEM24013 require 1 set of wires and ground
(see wiring diagram)
Model EEM24018 requires 2 sets of wires and ground
(see wiring diagram)
Model EEM24024 and EEM24027 require 3 sets of wires and ground
(see wiring diagram)
Model EEM24036 requires 4 sets of wires and ground
(see wiring diagram)
Please see required wire gauge on the next page
Each set of wires must be connected to its own individual double pole breaker
Installation Instructions
STEP 1:
Take each wire pair and connect them to one breaker (see wiring diagram). Make sure that each breaker is
connected with one black wire and one red wire
STEP 2
:
Using a suitable wire gauge that meets all applicable electrical codes for the size of the breakers used, run the
correct sets of wire from the home’s main breaker panel to the tankless water heater.
STEP 3: A separate ground conductor for each incoming circuit is required.
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 the air has been purged from the water lines prior to turning on power to the unit. Refer to
STEP 2 in the plumbing installation section.
CAUTION: Ensure that you have made the correct connections. You must follow the wire connection as shown
in 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 set
up. We highly recommend that this is done with the homeowner present.
