2.0 INSTALLATION INSTRUCTIONS

WARNING: Electrical and grounding connections must comply with
applicable portions of the National Electrical Codes.

WARNING: Plumbing connections must comply with applicable health,
safety and plumbing codes.

1. Select a location to provide drainage directly below the draw-off valve. Allow
sufficient rear clearance from the wall for the kettle cover to lift upright freely without
obstructions. Allow for clearance to side service panels.

2. Level the unit. Then mark anchoring hole locations through flanged adjustable feet.

3. With hole locations marked, drill holes and insert expansion plugs to accommodate
5/16" size lag bolts.

4. Reposition the kettle. Check the level again.

5. Bolt the kettle down and seal with a high grade sealing compound. Sealant must be
applied not only to bolt heads but around the flanges and must be making contact
with floor surface to meet N.S.F. requirements. Wipe off excess sealant
immediately.

6. Connect the steam line to the kettle (3/4" i.p.s., 5 psi minimum to 30 psi maximum, or
45 psi with optional high pressure operation).

7. If the incoming steam pressure is greater than the kettle maximum operating
pressure, then a pressure reducing valve (supplied by others) must be installed in
the line.

8. Connect hot and cold water supply to the faucet.

INSTALLATION INSTRUCTIONS (Continued)

9. A control box with a power supply equivalent to electrical rating of the unit should be
located nearby. A waterproof electrical connection for the power supply to the unit
must be provided.

10. The relief valve on the kettle must not be adjusted or closed off as it is set to relieve
excess pressure in the kettle.

11. If large amounts of water accumulate in the steam line, it will be necessary to install
one or more ball float traps (supplied by others) in the line to eliminate the water.

12. A steam line pressure gauge (supplied by others) is also recommended to determine
the actual amount of steam coming to the kettle.

13. Turn unit on when electrically connected, then check for proper operation.
