8.5 Connection for wastewater temperature control
(optional)
The wastewater can have a temperature of more than 150 °F (65 °C). Install a
temperature conditioning kit if a lower wastewater temperature is required by
local regulations.
1 Backflow preventer
2 Drain (On-site)
3 Drain inlet hose barb
Connection procedure:
1. Position tempering assembly, as required, behind the machine..
2. Connect cold water supply line to the backflow preventer (1), using a 1/2”
pipe fitting. If you are soldering, be sure to remove the union on the backflow
preventer. This will insure that the plastic internal parts do not melt.
3. Connect from drain (2) of the tempering assembly to an indirect waste drain
pipe. If required, the 1” barb can be removed and the drain can be
connected using 1” fittings and pipe.
4. Connect drain hose from the machine to the drain inlet hose barb (3) and
secure with wormgear clamp.
5. Turn on cold water and check for leaks.
6. Fill machine and operate. The drain water exiting the drain water tempering
assembly (2) should be no higher than 140 °F (60 °C).
