INSTALLATION, OPERATION, AND CARE OF
MODELS HSF3, HSF4, & HSF5
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.
