CLEANING & MAINTENANCE
1. Before cleaning, turn o the unit and let it cool down.
2. Carefully clean the equipment daily to promote proper operation and long life.
3. Steel surfaces must be cleaned with dish detergent diluted in very hot water using a soft cloth; do not use
abrasive powder detergents or corrosive substances. The use of acids can aect the unit’s operation and
safety. Do not use brushes, steel cottons, or abrasive disks made with other metals or alloys that may cause
rust stains due to contamination. For the same reason, avoid contact with iron objects. Do not use stainless
steel brushes, as they can cause long term damages.
4. Metal powder, metal shavings, and iron material in general can cause stainless steel to rust. Supercial rust
stains may be present on new equipment and they can be removed with a detergent diluted in water and a
scouring pad. If dirt is dicult to remove, a sponge may be used.
5. Do not use substances for cleaning silver and be careful with hydrochloric or sulphuric vapors rising from oor
washing products. Do not aim water jets directly on the equipment. After cleaning, rinse properly with clean
water and dry carefully with a cloth.
6. This equipment requires minimal maintenance. Despite this, we recommend that the user subscribes to a
maintenance agreement to have the equipment checked at least once per year by an authorized technician.
7. Before carrying out any maintenance or repair, disconnect the equipment from the gas network or cut o the
mains. Use only original spare parts supplied by Mainstreet Equipment.
8. If the equipment is not going to be used for a long period of time, it is advised to clean the equipment and
surrounding areas properly. Pour a small quantity of cooking oil on the stainless steel surfaces, carry out all
maintenance operations, and cover the equipment with a suitable material, leaving some openings to allow air
to circulate.
