WATER SUPPLY
Water quality is a major factor a󰀨ecting the performance
of your steamer. If you are unsure of water quality,
consult a local water treatment specialist and have the
water analyzed. Your water supply must be within these
general guidelines:
• Total dissolved solids: Less than 60 PPM
• Total alkalinity: Less than 20 PPM
• Silica: Less than 13 PPM
• Chlorine: Less than 1.5 PPM
• pH Factor: 7.0 - 8.5
Water which fails to meet these standards should be
treated by installation of a water conditioner. Failure or
malfunction of this steamer due to poor water quality is
not covered under warranty.
WATER & DRAIN CONNECTIONS
Drain
• 1” (25mm) IPS piped to open oor drain. No solid
connection.
• 24” length before open air opening (no bends or
elbows)
Cold Water
• 3/8” (10mm) tubing at 25-50 PSI (170-345 kPa)
The drain piping must consist of temperature resistant
material, greater than 160°F, and be of adequate diam-
eter not to cause ow restriction. Improper materials
may deform and cause restrictions, thus a󰀨ecting perfor-
mance.
Appliance is to be installed with backow protection in ac-
cordance with Federal, State or Local codes.

Installation Instructions
GENERAL
The SN-3E and SN-5E steamers are single compartment
electric pressureless steam cookers with
an internal electric steam generator that maintains water
temperature at approximately 205EF.
SN-3E is rated 7.5 kW as standard; 10 kW is optional.
SN-5E is rated 12 kW as standard; 15 kW
is optional.
At high altitude locations a lower temperature is required
to achieve atmospheric steaming.
Contact your authorized service o󰀩ce to have the ther-
mostat adjusted if the steamer will be
operated at high altitudes.
UNPACKAKING
Immediately after unpacking the steamer, check for pos-
sible shipping damage. If the steamer is found to be dam-
aged, save the packaging material and contact the carrier
within 15 days of delivery.
Prior to installation, verify that the electrical service agrees
with the specications on the machine data plate which is
located on the left side panel.
LOCATION
Allow space for plumbing and electrical connections.
Allow adequate access for operating and servicing the
steamer (36” at the front of the steamer and 15” above
the steamer).
LEGS (OPTIONAL)
If the optional 4” adjustable legs are used, remove the
four levelling feet on the bottom of the steamer.
FEET
Levelling Feet (standard) or 4” Adjustable Legs (Op-
tional)
Thread the four 2” levelling feet shipped in a bag inside
the steamer cabinet into the threaded holes on the bot-
tom corners of the steamer. Or, thread the four optional
4” adjustable legs into the threaded holes on the bottom
corners of the steamer.
LEVELLING
Using a spirit level or pan of water in the bottom of the
steamer, adjust the levelling feet or the feet on the ad-
justable legs to level the steamer front-to-back and side-
to-side. After the drain is connected, check for level by
pouring water onto the oor of the compartment. All water
should drain through the opening at the back of the com-
partment cavity.
ANCORING STEAMER (WITHOUT LEGS)
1. Place steamer in the desired location on the lev-
elled counter top and mark four corners. Remove the
steamer and drill ½” holes as indicated in Figure 1.
2. Apply a bead of RTV or other equivalent sealant
around bottom perimeter edge of the steamer. If an-
choring the steamer, this bottom seal is necessary to
meet NSF requirements.
3. Set steamer on counter and bolt down securely with
3/8 - 16 bolts (not supplied).
STACKING KIT
Follow instructions in the stacking kit when installing
stacked convection steamers.
