Rinse Aid Injection in UC, UW & HT

Undercounter LS5-6E / WT4-30E, Utensils Washer LU7 / WTU40, Hood Type
LS9-10EA-14EA / WT55-65 with atmospheric boiler and peristaltic rinse aid
dispenser.

Undercounter LS6E / WT30E and Hood Type LS14EA / WT65E with Water Softener built-in are not involved in this
change since they have rinse aid injection to the water softener assembly instead of directly to the boiler.

Water / rinse aid leakage from connection between rinse aid hose and boiler.
The rinse aid hose (in PE-HD) is cracked.
Since serial number 53800001 we have introduced a silicon hose between the

rinse aid hose and the boiler injection and since serial number 61600001 we
have introduced the reticular MDPE hose 0L1163 instead of PE-HD hose
049905 and the silicon hose (no spare part code).

Both silicon hose and MDPE hose are more reliable in case of combination of
mechanical, thermal and chemical stresses.

The new MDPE hose is perfectly interchangeable towards previous hoses.
