1.3. WATER CONNECTION
Must be carried out by an authorized technician according to
the national and local codes.
The machine must be operated with potable water. For water
with an extremely high mineral content, an external deminerali-
sation is strongly recommended.
! Water temperature:
• If possible, connect to warm water (max. 60 °C).
• Machines with drainwater/exhaust heat recovery:
If possible, connect to cold water (approx. 10 °C).
! Water hardness:
• Machines without softener: max. 3.75° Clark = 0.5 mmol/l.
• Machines with softener: max. 37.5° Clark = 5.3 mmol/l.
! Special feature of PREMAX model UPT:
• Additional separate warm water connection (marked red) for
quicker filling of wash tank.
• If the separate filling of the wash tank with warm water cannot
be realized on site, a HOBART trained service technician must
switch to booster filling via parameter adjustment (S20).
! Line flow pressure:
• Machines without softener: 0.5 - 10 bar
• Machines with softener: 0.8 - 10 bar
• If the line flow pressure is above 10 bar, provide pressure
reducer at source.
! Connect the union nut “A” (3/4”) of the water supply hose to the
site shut off valve.
! Do not kink or cut the supply hose.
! If an extended supply hose is required, use one of the same specifi-
cations as the original.
1.4. STEAM CONNECTION
(STEAM-HEATED MACHINES ONLY)
Must be carried out by an authorized technician according to
the local and national codes.
! Connection to steam supply (DN 20),
0.5 - 3.5 bar (max. 150 °C). See data plate!
! Dimension of steam and condensate piping has to be according to
the requirements.
! The machine is equipped with all necessary fittings.
! Make sure that permissible pressures and temperatures will not be
exceeded.
