FILL & FINAL RINSE CONNECTION (Fig. 5)
Fig. 5
Use
3
/4" pipe for the connecting line. A flowing pressure of 15 to 25 psig and a minimum temperature
of 180°F must be maintained at the machine for common water connection for a non-booster heat
machine; 110°F minimum temperature incoming water is required for machines equipped with an
optional 30
KW booster heater; and 140°F minimum temperature incoming water is required for
machines equipped with an optional 15
KW booster heater. For long runs, use larger pipe and insulation
to ensure adequate pressure and temperature. If flow pressure exceeds 25 psig, a pressure-reducing
valve (not furnished) must be installed in the supply line.
CAUTION: The water pressure regulator must have a relief bypass. Failure to use the proper
type of pressure regulator may result in damage to the unit.
A pressure gauge is provided for verification of proper water pressure.
STEAM CONNECTION (WHEN EQUIPPED)
CAUTION: Steam supply pressure must agree with steam trap selection. The steam trap
(supplied) will be for either 0 to 20 psig (flowing) or 21 to 50 psig (flowing).
The steam supply must be between 10 and 50 psig flowing pressure. If flowing pressure exceeds
50 psig, a pressure regulator (not supplied) must be installed in the supply line.
If flowing pressure is 10 psig, use 1" piping; if over 10 psig, use
3
/4" piping. Steam flow is controlled by
solenoid valves.
If machine is equipped with steam injector(s), one supply connection is required. For single-tank steam
coil installations, two connections are required, one for supply and one for return. For two-tank
steam coil installations, one common supply connection and two return connections (one per tank) are
required.
