3. Description
3.1 Construction
The wall-mounted FRANK hot water high-pressure module is a stationary,
electrically-heated machine. The machine consists of an enamelled chassis with wall
consoles, hot water tank made of stainless steel with electrical gilled pipes, high-
pressure pump with electric motor, cold water tank and a separate master control
cabinet.
On the pressure side the machine is equipped with a glycerine-dampered pressure
gauge, an overflow safety valve, a flow monitor switch, a pressure switch and a
pressure accumulator.
The construction and dimensions are shown in the basic circuit diagram.

3.2 Function
3.2.1 Functional diagram

- 5 -
3.2.2 Water and cleansing agent/Preserving agent system
The incoming water from the mains flows past the float valve into the water inlet tank.
The high-pressure pump collects the water and conveys it under pressure to the safety
spray lance.
Cleaning agent A or B can be added to the water through dosing valves via 2 solenoid
valves. For this purpose, the suction tubes for the cleaning agents are placed in the
tanks filled with cleaning agents.
The solenoid valves in the cleaning agent suction hoses shut off or open the intake of
cleaning agents in accordance with the programme selected on the control cabinet.
3.2.3 Safety spray lance with mechanical spray gun
The mechanical spray gun permits operation of the machine only when the safety
controllever has been activated. The spray gun is opened by activating the lever.
When the lever is released, the gun is closed, preventing any further release of fluid
from the spraylance.
When the gun is closed during operations, a pressure surge in the system is released, as
a result of which the machine is switched off by means of a pressure switch. After the
pressure has fallen to approx. 20 bar, the machine is switched on again by a second
pressure switch, when the lever of the gun is activated once again.
The spray gun is a safety device. Repair works are to be carried out by
experts only.
3.2.4 Overflow safety valve
The overflow safety valve with integrated electric pressure switch protects the
machine against excessive pressure and is designed in such a manner that it cannot be
set above the maximum admissible operating pressure. The check nut of the
handwheel is sealed with lacquer.
Replacement, repair works, and settings are to be carried out
by experts only.

- 6 -
3.2.5 Level switch
The tabular radiators in the hot water tank are monitored by the level switch. In case of
lack of water the tabular radiators are switched off automatically. At hot water
operation – programme “HOT” – the level switch protects also the high pressure
pump, which is also automatically switched off in case of lack of water.
3.2.6 Regulating thermostat/heating switch
The thermostat has a regulating function.
Thermostat and heating switch form a unit. Both of them are actuated by a
thermostat spindle and the turning button.
By setting the desired temperature, the heating is switched on.
By turning back the turning button anticlockwise until the limit has been
reached, the heating is switched off.
3.2.7 Pressure switch
The machine is equipped with two identical pressure switches. One of them has the
safety function of a pressure switch. It switches off the machine in the event of the
spray gun being closed.
The second pressure switch starts the machine when the spray gun has been opened,
after the pressure has fallen to approx. 20 bar. The pressure cannot be regulated on
the pressure switches.
Pressure switches are safety devices. Replacement and repair
works may be done by experts only.
3.2.8 Pressure accumulator (pulsation damper)
The pressure accumulator dampens the pulsation of the high-pressure pump and
delays the restarting of the machine in the event of a leakage in the pressure system.
The filling pressure of the accumulator is 20 bar and must not fall below. Faulty
accumulators are to be replaced immediately.
3.2.9 Control cabinet
All electrical components are centrally installed in the control cabinet. A main and
emergency switch is installed in the front door and can be operated from outside
the cabinet.
Maintenance and repair works may only be carried out by experts
with the main and emergency switch being switched off and
being protected against unintentional starting.

- 7 -
3.2.9.1 Fuses
The fuses protect the electrical components of the control circuit in the event
of faults.
3.2.9.2 Motor protection
The motor is protected against overloading by an overload release device. In the
event of overloading the release device switches off the motor and restarts it again
automatically after it has cooled down. If the motor is repeatedly switched off by
the release device, the cause of the fault is to be eliminated.
3.2.9.3 Automatic cutoff system
By closing the spray gun the machine is switched off by means of a pressure switch,
the time sequence of the automatic cutoff system starts. During the time sequence
the machine remains in operating condition. By opening the spray gun during the
time sequence the time gone is deleted, which means, when closing the spray gun
again, the time sequence starts from zero.
After the time to be set on a time relay has gone by, the operating condition is
deleted.
For restarting the machine, the start button on the control box at the washing site
must be switched on.
At works the time of the automatic cutoff device is set to approx. 5 minutes.
In case the time for the operating condition has to be changed, the setting has
to be carried out by an expert on the corresponding time relay in the main
switch cabinet.
4. Installation
4.1 Location
The machine must not be installed and operated
in fire and explosion hazard areas.
Frost protection
The machine, the long-distance pipings and the washing bays
have to be installed in such a manner to protect them from
frost.
The machine is designed for stationary installation on a
solid wall.
The satisfactory solidity of the wall
must be checked and approved by an expert
on site. If there is no sufficient solidity
of the wall for wall installation, the
machine is to be mounted on a scaffolding.

5.2 Nozzles and recoiling forces
The approved nozzle is adapted to the maximum flow rate, the admissible pump
pressure and to the direct connection of a high-pressure hose pipe DN 8 x 10 m.
The appropriate nozzle size is to be taken from the table below.
For long-distance pipings and/or longer hose pipes larger nozzles are to be used.
The nozzle size is to be chosen and laid down in such a manner that the working
pressure of the high-pressure stage (HD), indicated in section 2, is not exceeded.
When handling safety spray lance, the recoil should be taken into
account, and the fact that torque is produced by the recoil when
angled spray lances are in operation. This torque increases with the
length of the lance.
