COUNTERTOP CONVECTION STEAMERS
PLEASE KEEP THIS MANUAL FOR FUTURE USE

GENERAL

The HSF 3, 4, and 5 Steamers are single compartment pressureless steam cookers with an internal electric steam generator that maintains water temperature at approximately 205°F (96°C). HSF3 is rated 7.5
At high altitude locations a lower temperature is required to achieve atmospheric steaming. Contact your local Hobart-authorized service office to have the thermostat adjusted if the steamer will be operated at high altitudes.
KW as standard; 10 KW is optional. HSF4 is rated 10 KW. HSF5 is rated 15 KW.

INSTALLATION

UNPACKING
Immediately after unpacking the steamer, check for possible shipping 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 2" (5 cm) on the sides and 6" (15 cm) on the back for proper air circulation. Allow adequate access for operating and servicing the steamer (36" [91 cm] at the front of the steamer and 15" [38 cm] above the steamer).
LEVELING FEET (STANDARD) OR 4" (10 CM) ADJUSTABLE LEGS (OPTIONAL)
Thread the four 2" (5 cm) leveling feet, shipped in a bag inside the steamer cabinet, into the threaded holes on the bottom corners of the steamer. Or, thread the four optional 4" (10 cm) adjustable legs into the threaded holes on the bottom corners of the steamer.
