ATW/BTW UNIT OPTIONAL PARTS

IMMERSION HEATER (1Ph 1/3kW)

PAC-IH01V2-E / PAC-IH03V2-E

WARNING

●

INSTALLATION MANUAL

If the ATW/BTW unit has already been connected to the power supply ensure circuit breaker is off before carrying out

electrical work.

If the immersion heater is installed incorrectly or modified after installation by the user, water leakage, electric shock or

fire may result.

All electrical work should be performed by a qualified technician according to local regulations and the instructions given

in this manual.

The immersion heater must be powered by a dedicated power supply and the correct voltage and correctly sized circuit

breakers must be used.

Connections must be made securely and without tension on the terminals.

The included component parts of the PAC-IH01V2-E / PAC-IH03V2-E IMMERSION HEATER (1Ph 1/3kW) shall be used

only for the purposes indicated in the installation manual.

● Before starting installation, read the following description together with the installation manual included with the ATW/BTW unit.
● Please read carefully and observe fully the following safety precautions.

Precaution that must be observed to prevent injuries or death.

WARNING

After installation carry out a test run to ensure correct operation, then explain operation method and safety precautions to the

end user.

Tell your customers to keep this installation manual together with the operation manual, and when they give or sell this

machine to any other person include this installation manual and operation manual with it.
