Installaon and Operaons Manual
A power block is provided for incoming power to the EME/EMD.
This circuit supplies power to all of the controls, internal pump,
and immersion heater (if equipped).
Reference the electrical data for circuit sizing.
Due to the extensive use of digital controls within the EME/EMD,
Enertech recommends the use of Type 1 or Type 2 surge
protecve devices (SPD). The system may be protected as part
of a whole house surge protector or the branch circuit can be
protected using an SPD such as the Compressor Defender
. Please check the NEC Arcle 285 and
your local codes regarding the use of SPDs.
