INSTALLATION 
ELECTRICAL CONNECTION
!
Damage to the appliance and the environment:
Observe the type plate. The specifi ed voltage must match 
the mains voltage.
DANGER: Electrocution
Before beginning any work on the electric installati-
on, be sure that main breaker panel switch is „off“ to 
avoid any danger of electric shock. All mounting and 
plumbing must be completed before proceeding with 
electrical hook-up. Where required by local, state or 
national electrical codes the circuit should be equipped 
with a „ground fault interrupter“.
DANGER: Electrocution
As with any electric appliance. failure to electrically ground 
appliance may result in serious injury or death.
  The appliance should be connected to a properly grounded 
dedicated branch circuit of proper voltage rating. In installa-
tions with several appliances, each appliance requires an inde-
pendent circuit. Please refer to the technical data table for the 
correct wire and circuit breaker size.

  The wire must be fed through the rubber seal located be-
tween the hot and cold water connections. Then feed wires 
through strain relief clamp and tighten clamp down on wire. 
The “live” wires must be connected to the slots on the terminal 
block marked L and L. The ground wire must be connected to 
slot marked with the ground symbol. Strain relief clamp with 
screws and rubber seal are provided.

  Connect the lead of the electronic temperature control to posi-
tion „A1“ in order to get the maximum outlet temperature of 
140°F (60°C).
The maximum temperature can be limited to 109°F (43°C):
  Connect the lead of the electronic temperature control to posi-
tion “A2”.
  Reinstall the plastic cover.
10.2 Terminal block
We recommend using stranded wire to connect to the terminal block. 
Crimp a ferrule over stranded bare wire to ensure a good connection. 
Consult the chart below for the recommended torque amounts on 
the terminal block screws. 
Screw Diameter (mm) Torque (N•cm) Torque (lbf•in)
2.8 30-40 2.65-3.54
2.8-3 35-50 3.09-4.42
3-3.2 50-60 4.42-5.31
3.2-3.6 60-80 5.31-7.08
3.6-4.1 90-120 7.96-10.62
4.1-4.7 120-180 10.62-15.93
4.7-5.3 150-200 13.27-17.7
Using the proper torque specifi cations to secure wire to the wiring 
block helps to avoid personal loss or property damage.
See 14.3, “Data table”, pg. 9 for information on the proper wire 
gauge size.
