Precaution Explanation
Never interchange
water valve electrical
connections. On machines with air-operated water valves, it is permissible to ex-
change the pneumatic control lines, if the cold and hot connections
were accidently plumbed in reverse.
Install any vacuum
breaker(s) provided or
required. If vacuum (siphon) breaker(s) are provided for fresh water connection
(s), but not already installed, install them as shown on the options di-
mensional drawing. If vacuum breakers are required by code, but not
provided, obtain and install the required hardware.
Install any water
strainers provided or
required. If water strainer(s) are provided for fresh water connections, install
them between the machine and incoming water. For machines with
garden hose type water inlets, use 40-mesh strainers.
Install a union and a
shutoff valve at each
hard-piped connection. Obtain and install the necessary hardware to permit hard-piped con-
nections to be shut off and disconnected at the machine for mainte-
nance. For the valve, use a ball valve, not, for example, a globe valve.
Connect a dry supply
injector flush inlet to
hot water and regulate
it. If the machine has a dry supply injector with an external flush water
connection and hot water is available, provide hot water to this inlet.
The machine will be supplied with a pressure regulator. Install this
hardware at the flush water connection and confirm that the regulator
is set to 28 psi (193 kPa). Steam in the hot water line will cause the
supply injector to malfunction.
