Preparing The Machine - Hobart EF 40 Installation And Operation Manual

IV. Hygiene
To ensure that the machine is hygienic, the maintenance operations indicated in the
relevant paragraph of this manual must be carried out regularly. In addition, the machine must be
treated to sanitise it from time to time using adequate, non-corrosive, commercially available
products.
To ensure that dishes are hygienic, follow these general rules:
• clear the dishes of any dry residue or solids before washing.
• replace the washing solution a number of times a day if necessary.
• so as not to contaminate clean dishes, do not use: brushes, tea cloths, or non-sterile cloths,
sponge mats, or any other materials that can hold bacteria. Use disposable cloths or drainage
racks.
• clean surfaces on which the dishes are placed frequently, using suitable commercially available
products.

2. Preparing the machine

I. Chemical washing and rinsing products.
The choice and dosage of detergents are important both for good washing results and for
the lifespan of the machine.
Detergents are not supplied with this machine. Therefore we advise you to make contact with
professional producers who are able to recommend the best solutions for all types of washing.
Follow the dosages indicated by the detergent manufacturer. Any other dosage may produce
unsatisfactory results.
This machine uses:
− Washing detergent
− Rinse aid for rinsing.
There are powder, liquid and solid products on the market. Choose those intended for
industrial washing that are low foaming.
When the dosage unit provided is used:
- only use detergents with a recommended dosage of less than 5g/litre
- only use rinse aids with a recommended dosage of less than 1.5g/litre
The use of products having a different concentration will provide unsatisfactory results.
Some detergents and rinse aids are subject to aging and temperature. Store them in strict compliance
with the manufacturer's instructions. Do not use detergents that have not been stored correctly.
Detergents and rinse aids are chemical products that are potentially dangerous. NEVER put
your bare hands into the washing solution. Where this must be done, wear protective gloves. If
the solution comes into contact with your eyes, rinse with abundant amounts of running water and
contact a doctor, indicating the type of detergent used.
Remember that detergent and rinse aid are products that unfortunately produce pollution in rivers
and seas. Therefore, it is important never to exceed the recommended dosage.
