Installation
WATER INLET CONNECTION
The National Sanitation Foundation requires the following for an NSF approved water hook-up:
1. A quick disconnect water connection or enough coiled tubing so that the machine can be moved for cleaning
underneath.
2. An approved backflow prevention device, such as a double check valve to be installed between the machine and
water supply. On units plumbed to permanent water line, installation of a water filter/softener system is recommended
to prevent lime and scale build up in the machine. On units pumping from remote water container, filtered water
is recommended to prevent lime and scale buildup in the machine.
3. Water pipe connections and fixtures directly connected to potable water supply shall be sized, installed and maintained
in accordance with Federal, State, and Local codes.
WATER HOOK-UP
1. Install the 4" legs and hand tighten. Install the plastic drain tray onto the
drain tray bracket and install drain grid. (Note: The drain tray is provided with
a drill-out port to allow for plumbing to a drain.)
2. Remove front splash panel for access to water hook-up. (see Figure 1)
3. Ensure the 3/8" water supply hose has sufficient length to allow the machine
to be moved for cleaning or service. Supplying hot water to the machine will
greatly increase the capacity of the machine. The use of copper tubing is
required to prevent rupture when using a hot water supply. A maximum inlet
water temperature of 160°F (71°C) is recommended.
4. Flush the water line to purge any debris from the supply line.
5. Connect a 3/8" water line to the 3/8" male flare connection.
6. Ensure water supply to machine is within 20 to 100psi. Install a pressure
regulator if pressure is too high.
7. Turn on water supply and check for leaks.
Only qualified service personnel should perform installation of this appliance.
Improper installation could result in serious injury or death.
Never use the ground conductor as a neutral conductor. Serious injury or
death could occur in the event of a fault condition.
Always disconnect power to the machine before servicing or cleaning. Risk
of electric shock is present which can cause serious injury or death.
