6.5 Cooling of heating thermostats
At bath temperatures slightly above the room temperature (approx. 2 – 5 K) operation is possible at a low pump level
(1 or 2) without cooling. For temperatures below room temperature cooling must be used.
With the immersion thermostat use a cooling coil ( 6.1).
With bath and circulation thermostats the cooling coil is already built in as standard.
Connect external cooling fluid to the cooling coil. At temperatures above 20 °C, fresh water can be used. Ensure the
lowest possible water consumption.
6.6 First switch-on
Make sure that the details on the name-plate match mains voltage and frequency.
Use of inadmissible mains voltage or frequency
Compare the rating label with the available mains voltage and
frequency.
Note for electric installation on site:
The devices must be protected with a 16 ampere circuit breaker fitted during installation.
Exception: Devices with 13 ampere UK plugs.
Note:
The device mains plug is used as a mains disconnection component.
The mains plug must be easily recognizable and easily accessible.
Only connect units to sockets having a safety earth conductor (PE). No liability is accepted for incorrect mains
connection.
Make sure that if not using an external consumer, the pressure nozzle is closed off or short-circuited to the return
nozzle.
Make sure that the unit is filled according to section ( 6.3).
