ELECTRICAL REQUIREMENTS
Electrical Characteristics
HT-E
All electrical ratings provided in this manual are for reference
only. Always refer to the machine data plate to get exact electrical
information for this machine. All electrical work performed on
machines should be done in accordance with applicable
local, state, territorial, and national codes. Work should only
be performed by qualied electricians and authorized service
agents.
Note that all electrical wiring used in the HT-E must be rated, at
a minimum, for 212 °F (100 °C), and that only copper conductors
must be used.
Where applicable, heating element amperage draws have been
adjusted for the assumed input voltage. The manufacturer
assumes incoming voltages will be either 208 or 230 Volts. Some
heating elements used in the machines are rated for other voltages,
such as 240 Volts and 480 Volts. Always verify the amperage
draw of the machine in operation when sizing circuit protection.

INSTRUCTIONS
INSPECTION
Do not throw away
packaging if damage is
evident!
UNPACKING
PLUMBING
The plumber must ush
the incoming water line!
Before installing machine, check packaging and machine for damage. Damaged
packaging might be an indication of damage to the machine. If there is any type
of damage to both packaging and machine, do not throw away the packaging. The
machine has been inspected at the factory before shipping and is expected to arrive
in new, undamaged condition. However, rough handling by carriers or others might
result in damage to the machine while in transit. If this occurs, do not return machine to
the manufacturer. Instead, contact the carrier and ask them to send a representative
to the site to inspect the damage and request that an inspection report be completed.
Contact the carrier within 48 hours of receiving the machine as well as the dealer that
sold you the machine.
The machine should be unpacked and removed from the pallet before installing. Open
the front door and remove all materials from inside. Once unpacked, verify there are no
missing parts. If a part is missing, contact the manufacturer immediately.
All plumbing connections must adhere to local, state, territorial, and national codes.
The installing plumber is responsible for ensuring the incoming water lines are ushed
of debris before connecting to the machine. Note that chips and materials from cutting
processes can become lodged in the solenoid valves and prevent them from opening
or closing. Any valves found to be fouled or defective because of foreign matter
left in the water line, and any subsequent damage, are not the responsibility of the
manufacturer.
A water hardness test
must be performed.
WATER SUPPLY
CONNECTIONS:
WATER HARDNESS
HIGHER THAN 3 GPG
i
A water hardness test must be performed. If water hardness is higher than 3 GPG,
install a water softener or install the optional Scale Prevention System (SPS). See the
next section and the Plumbing Options page for more information on the SPS.
If water hardness is higher than 3 GPG and a water softener is not being used, install
the SPS into the water line between the facility water line and machine water line.
Observe proper inlet/outlet water directions. A water shut-o valve should be installed
before installing the SPS to allow access for service. The water supply must be
capable of the minimum “ow” pressure at the recommended temperature indicated
on the data plate.
