In this chapter you will find the information required for safe transport of the proofer, as well as assembly and connection of the proofer.

4.1 Unpacking the proofer

The proofer is packed onto a pallet in the factory. Unpack the proofer and dispose of the packing material in an environmentally friendly way.

4.2 Transporting the proofer

The proofer has no suspension points.

The proofer stands on rollers.

=> The proofer has to be moved in a horizontal position. Danger of tilting!

Lift the proofer carefully during transport!

WARNING


Transport the proofer carefully!

Do not stand under or reach under raised, suspended loads!

WARNING


Do not position yourself under suspended loads!

4.3 Location

In order to guarantee correct function, the proofer must be assembled in a dry, frostproof room.

WARNING


Place the proofer on a suitable substrate!

The proofer must stand on a horizontal, secure, non-tilting base which can withstand the weight of the proofer.

CAUTION

Heat accumulation

Do not cover exhaust air and vent slots!

To prevent heat accumulation, place the proofer at least 20 mm away from the wall.

The air vents on the sides and on the back must not be covered.

Page 14

For servicing purposes, the proofer must be pushed 1 metre away from the wall. Therefore, ensure there is sufficient clear space around the proofer.



4.4 Electrical connection

The requisite mains voltage is 230V at 50 / 60 Hz depending on the model. Please refer to the electrical connection values on the type plate or in the „Technical Specifications“ chapter of this operating manual.

DANGER



Electrical connection of the proofer may only be carried out by an electrician according to electrotechnical rules.

Electrical fuse protection of the plug socket must be ensured with a fault-current circuit-breaker.

Observe guidelines from the VDE and the local power companies.

Use a separate fuse protected supply cable for each proofer. The cross sections of the connection lines conform with the power consumption and the local conditions.

In order to exclude mains fluctuations and undervoltages, the supply impedance should not fall below50mΩ . Your regional energy supplier will provide you with more information on this topic.

The mains plug must also be accessible after installation of the proofer in order to guarantee quick disconnection from the mains at all times. If this is not possible, then a device

(main switch) must be attached to facilitate disconnection from the mains.

The electrical connection is located on the back of proofer.

4.5 Water connection

• The water supply for the proofer must be of drinking water quality

(according to drinking water ordinance)

• The water must not be above 50°C.

The water supply line must have a water tap at the assembly location of the proofer.

Water supply line and tap must be provided by the customer.

The water supply hose must be a foodstuff compatible pressure hose ½“ with a ¾“ screw connection, tested according to DIN - DVGW (included in scope of delivery).

The connection must be fl exible so the proofer can be shifted

1 metre away from the wall for servicing.

The dirt filter must be cleaned and installed at the water connection point on the back of the proofer.

A tap with pipe aerator and backflow preventer, tested according to DIN - DVGW, must be used for the water connection.


Page 15


4.5 Water connection

CAUTION

Water damage

Turn off the water supply after operation!

The stop cock should only be opened when the proofer is running and must be closed again afterwards.

Connect the water supply hose at the water connection on the back of the proofer and to the water supply line.

Water softening

Water softening is recommended with water that has a very strong lime content (without chloride contamination). The water hardness after the water treatment unit may be at most 6 dH.

Systems with H+ ion exchangers (such as is usual with dishwashers) are prohibited. These systems lead to sodium deposits and to common salt related delay in boiling.

Fine fi lters

We recommend a micro filter with a fineness of 5 - 15 µm for impurities in the water due to sand, iron particles or suspended solids.

Activated charcoal fi lter

An activated charcoal filter has to be installed upstream in the event of strong chlorination

Cl² of the water over 0.2 mg/l (corresponds to ppm) (information from your water supplier).

Reverse osmosis unit

Only if chloride concentrations Cl are above 150 mg/l (corresponds to ppm, information from water supply) must a reverse osmosis unit be provided due to the risk of corrosion - also, observe the minimum / guide value of 100 µS/cm.

The following water fl ow rate has to be observed when choosing a fi lter:

• Average water consumption

• Max. flow quantity (determined by the size of the filter connection diameter).

The recommendations are supplemented on the basis of test results.

Filters can be purchased from WIESHEU GmbH and service partners.

We recommend Britta filter systems.
