INSTALLATION AND SAFETY INSTRUCTIONS

1. The SH series of immersion heater s are designed exclusively for the auxiliary heating
of water in closed or open containers. A built-in electric heater with flange of the R
series should be used as the main heater.
2. During operation, the heating element and sensor tube must be sufficiently immersed
from all sides in water. The thermally induced water flow may not be impeded.
3. The SH must be installed in horizontal positions only, the length of the 6/4" fitting may
not exceed 75mm. An area in front of the fitting equal to the installation length +
50mm is to be kept clear for mounting, etc.
4. The unheated zone of the immersion heater amounts to 100 mm from the sealing sur-
face.
5. The heating element is to be disconnected from the power supply prior to any work on the
appliance.
6. The ambient temperature at the casing may not exceed 80°C.
INSTALLATION
In addition to the effective norms and regulations, the connection requirements of the
local power station and water supply company are to be observed. The electrical con-
nection may only be established by a licensed electrician.
1. Prior to installation, ensure that the heating rods do not touch one another. If neces-
sary, adjust them by hand.
2. Remove the protective cap.
3. Install the immersion heater with the supplied flat gasket into the planar fitting and/or
seal with hemp, PTFE or similar. Use a SW60 open-jawed wrench for this. Installation
using pliers or the like is not permitted.
4. The connection cable must be inserted through the accompanying screwed cable
gland into the connection space of the immersion heater. The connection cable must
be of a sufficient rating.
5. Establish the electrical connection (according to circuit diagram), ensure the connec-
tion voltage is correct. The entire wiring must be checked according to the circuit dia-
gram before initial operation of the appliance.
6. The immersion heater with a rated power of 2 kW upwards are by default y-connec-
ted three-phase systems of 3 - 400 Volts, designed for direct control. The neutral
point may not be connected to ground. The 1.5 kW heating element is wired for
monophase 230V. For power ratings up to 3 kW (see table: mains voltage), a mono-
phase connection with direct control for 230 Volts is possible, whereby the heating
