2.4 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) at the machine. 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.
– All pipework has to be insulated with water and heat resistant material.
2.5 ADJUSTMENT OF SHUT-OFF VALVE FOR STEAM
SUPPLY
– The built-in shut-off valve is equipped with an adjustment device (A) to
limit the steam flow rate. A special tool is necessary for
adjusting the valve-seat.
– The correct adjustment is very important particularly for higher pres-
sure, and therefore must be done by a HOBART trained service techni-
cian at first installation or after any changes are done at the customer
site.
– The adjustment is correct if the heating-up time of the boiler is as long
as the shortest wash cycle, while the valve is opened to maximum.
– If adjusted too far open pressure shocks may occur when the solenoid
valve closes. This could cause damage at the installa tion. If adjusted
too far close the required heating-power cannot be achieved.
2.6 DRAIN CONNECTION
– Connection between machine and site drain must not exceed max.
height of 0.80 m.
– Do not place the drain hose loosely on the floor (the hose could be
rubbed through). Fix it at site!
– Do not kink the drain hose.
