2. INSTALLATION
This chapter is for installation purposes only, it contains no operational
information. The installation and, if necessary the maintenance and the
disassembling, must be carried out by a qualified electrical installer. The
installation must be compatible with local regulations.
Check the maximum circuit length for your circuit breaker in the next
table:

20A 180 m 100 m 100 m
Multiple units on multiple power point can be used if longer heating cables
are required. Up to 9 units can be connected on three phase systems via
the network configuration.
2.1 Disassembling the unit
Always switch off the mains supply (circuit breaker) before opening the
unit. Several touchable parts inside the unit are directly connected to
the mains voltage.
The HWAT-ECO has a removable top lid. Both top and bottom of the box
have electronic parts and are connected to each other by a 14-pin connec-
tor. First unscrew the four screws in the lid. Pull the lid carefully upwards,
not sideways! Inside the unit an ABS separation sheet will help to guide
the connector when disconnecting. See 5.5 Diagrams
and .
Closing the box
Position the lid in front of the wall-mounted bottom unit. The separation
sheet inside the unit will help to guide the lid and the connector. Push the
lid gently towards the bottom unit, the last part will offer some resistance
because of the connector pins.
2.2 Wall mounting instructions
The unit has two mounting options.
1. Inside the bottom part there are two holes, with the two supplied
screws and sealing rings the unit can be mounted to a wall.
