2.0 INSTALLATION INSTRUCTIONS

This steamer was inspected before leaving the factory. The transportation company
assumes full responsibility for safe delivery upon acceptance of the shipment.
Immediately after unpacking the steamer, check for possible damage. If the steamer is
found to be damaged after unpacking, save the packaging material and contact the
carrier within 15 days of delivery.

Prior to installation, verify that the electrical service agrees with the specifications on the
machine data plate which is located on the left side panel.

LOCATION

Allow space for plumbing and electrical connections. Minimum clearances are 3" (76
mm) on the sides and 6" (152 mm) on the back for proper air circulation. Allow adequate
access for operating and servicing the steamer, 36" (915 mm) at the front of the steamer
and 15" (381 mm) above the steamer.

LEVELING AND ANCHORING

1. Using a spirit level or pan of water in the bottom of the steamer, adjust the leveling
feet to level the steamer front-to-back and side-to-side.

2. Mark hole locations on the floor through the anchoring holes provided in the flanged
adjustable feet. Remove the steamer and drill holes at marked locations on the floor.
Insert proper anchoring devices.

3. Set steamer back in proper position.

4. Install bolts through anchoring holes and into anchors to secure the steamer to the
floor. Seal bolts and flanged feet with Silastic.

5. After the drain is connected, check for level by pouring water onto the floor of the
compartment. All water should drain through the opening at the back of the
compartment cavity.

ELECTRICAL CONNECTION

WARNING: Electrical grounding connections must comply with
applicable portions of the National Electrical code and/or other local
electric codes.

WARNING: Disconnect the power supply to the appliance before
cleaning or servicing.

Make electrical connection through the 1-1/8" (29 mm) diameter hole provided using 3/4"
(19mm) trade size conduit. Refer to the wiring diagram located inside the right side
panel. Use 90°C minimum insulated wire.

PLUMBING CONNECTIONS

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

The water supply inlets are provided with 3/8" (10 mm) compression fittings for 3/8" O.D.
copper tubing. The water supply line pressure should be 25 - 50 psi (170 - 345 kPa) for
each line. The water supply to the generator tank is separate from the water supply to
the cooling system where steam is condensed before entering the drain line.

Install line strainers (not provided). A manual shutoff valve for each supply line must be
provided convenient to the steamer.

We recommend treated water feeding the boiler inlet supply, and untreated water
feeding the cooling system inlet. Hook-ups are labeled on the back of the steamer.
