2.0 Hazard information
We pride ourselves on providing the best possible device safety, among other outstanding
product characteristics.
Despite all the safety precautions, however, there are always potential hazards with even the best
devices if they are not handled properly.
For this reason and in your own interests, we have summarised the potential hazards below.
Important information
for your safety that
The machine must only be connected and started up for the
first time by customer service.
you should always
observe:
Maintenance and repair work may only be performed by
customer service using original spare parts.
The built-in safety equipment must never be modified.
Caution! Risk of scalding!
There is a risk of scalding in the mulled wine
dispensing area.
Caution! Health hazard!
When using cleaning agents, observe the precautions on the
cleaning agent packaging. During the cleaning procedure,
cleaning fluid flows out of the mulled wine outlet.
3.0 Safety information
General information
Maintenance work on the mulled wine device may only be performed by trained customer service
personnel.
Stoppage
1. If the machine is not used for a longer period of time, it must first be cleaned thoroughly. If
there is a risk of freezing, the machine must be drained first to avoid frost damage.
2. After a stoppage of several weeks, we recommend cleaning the machine before starting it up
again.
Preventive measures against consequential damage
Every technical device is fundamentally a source of operational risks, particularly during
unsupervised operation.
For consequential damage of any kind outside the device, all claims against the manufacturer
and customer service are excluded unless liability is expressly prescribed by law.
We therefore recommend that the owner of the device take suitable measures to prevent
damage, in accordance with the specific local application and operating conditions.

Intended use
Selbach hot beverage devices are intended for use in the hospitality industry and at outdoor
events. Selbach hot beverage devices are the ideal solution when it comes to effortless and clean
heating up of mulled wine, fortified tea etc.
The hot beverage device is only approved for the aforementioned range of uses and is not
suitable for heating up liquids with a high alcohol content, chemicals etc.

6.0 Installation
Installing the machine
To ensure trouble-free operation, the mulled wine heater must be positioned on a level surface.
Make sure that there is sufficient space available to connect the beverage lines.
Select an installation site where the equipment is protected against wet conditions.
Also make sure that the connection cable is not kinked or pinched and goes straight to the
socket. The mains plug must be easily accessible at all times.
Preparing for installation
Route the mulled wine supply line (G 5/8”) and the power connection directly to the machine.
This preliminary work is to be arranged by the customer: the owner of the machine shall
commission a state-licenced dispensing equipment technician to perform the work, taking into
consideration general provisions and local requirements. Feedthroughs and drilled holes in
counters or worktops for the machines must be positioned so that live parts cannot be touched.
Caution! Do not alter the hose materials and hose lengths in the device.
7.0 Electrical connection
All machines are electrically heated. The 8.4kW machine is connected to 400 V three-phase
alternating current with a neutral line (N). The socket or three-phase outlet with easily accessibly
master switch is included in the scope to be provided by the customer and must be executed in
accordance with DIN VDE 100. To improve safety, the device should be protected by an
upstream ground fault circuit interrupter with 30 mA rated fault current (DIN VDE 0664).
No additional appliances may be connected to the supply lines.

8.0 Initial start-up
1) Connect the beverage lines, check for any leaks.
2) To operate the built-in gas pumps, connect the pressure lines (see page 12). Make sure to
handle the cylinder pressure reducer correctly if using CO2or nitrogen. Alternatively, you can
also use dry, clean compressed air.
To ensure optimum beverage delivery, set a pressure of approx. 1.5 –3 bar, depending on
the length of the beverage line (max. 8 m). The maximum flow rate is 0.2 l in 5-6 seconds.
To operate the pump, you can choose from:
- CO2
- Nitrogen
- Compressed air
3) Connect to the mains.
4) Switch on device, set the desired temperature.
5) To operate the built-in electric beverage pumps, switch on the switches for the corresponding
beverage lines (1, 2 and/or 3).
When setting the temperature, note that an excessively hot dispensing
temperature can cause spray at the tap.
Risk of scalding!
Caution! There is a risk of scalding in the dispensing area of the beverage outlets.
When the beverage containers are empty, there is a risk of spraying.
The maximum dispensing temperature depends on the alcohol content and the
altitude.
Once the operating temperature is reached, the device is ready for use.
(Heating switches off, orange indicator light off).
9.0 Frost level
To prevent frost damage in the mulled wine heater, you can set a frost level on the thermostat. To
do so, turn the thermostat to the lowest temperature (do not switch it off). Switch off the electric
pumps at the corresponding switches.
10.0 Shutdown
1) Switch off device
2) Pull out mains plug
3) Switch off pressure supply
4) Open taps until pressure equalises
6) Remove the beverage lines

11.0 Cleaning
In any hospitality situation, hygiene depends on three components: food hygiene, workplace
hygiene and personal hygiene. To ensure an unadulterated, pristine product quality, all three
components must interact seamlessly.
To ensure appropriate cleanliness and sterility when cleaning the OTHG 105 above-counter
heating device, always use a chemical cleaning method. Cleaning with water only does not
eliminate microbes.
Cleaning and disinfection intervals
Immediately after first start-up
Immediately before and after interrupting operation for a week or more
Immediately when changing beverage types
The parts that come into contact with beverage and air should be cleaned once a day
(e.g. part of the tap fitting/outlet valves, drip tray)
When in operation, no later than after 7 to 14 days
Outlet spouts on the taps
The outlet spouts are flushed with a cleaning ball. This prevents foam and beverage residue from
drying out and keeps the ventilations holes in the taps free and functioning. This measure means,
for example, that there are no nutrients for insects to consume, thus preventing transmission of
undesired contamination.
We recommend flushing at the end of operation, as well as before and after longer breaks in
operation.
Check the cleaning ball at regular intervals for internal contamination.
Beverage lines
Beverage lines
In the device version with a beverage pump, the device can only be cleaned chemically. Mix the
cleaning agent as per the manufacturer’s instructions and pump it through the pumps like a
normal dispensing operation. Leave it for the time specified in the manufacturer’s instructions.
After cleaning, rinse the system with drinking water (min. 5 l per line) until all the cleaning agent
has been flushed out. If possible, check that there is no more cleaning agent using suitable tests
(e.g. pH indicator test strips).

Housing
Before cleaning the equipment, disconnect the mains plug!
Do not allow the device to come into direct contact with water, simply clean it with a damp cloth
and a little dishwashing detergent.
11
Cleaning agent and disinfectant requirements
The cleaning agents and disinfectants used must not attack the surface finish of components and
lines.
Use only suitable alkaline cleaning agents, not agents containing chlorine (if possible, with SK
mark or clearance certificate).
The agents used must not affect the beverage.
The devices and beverage lines must be cleaned in accordance with the applicable cleaning
regulations (DIN 6650-6).
