Electrical Shock Hazard
Electrical shock can cause severe injury, death or property damage. Only
a professional technician, trained in electrical safety, should work on
this unit. Whenever the troubleshooting procedures make this possible,
turn off the power to the unit before working inside the cabinet. The only
exceptions would be when it is necessary to test the voltages between
the points listed in this manual. 120V AC is present in this unit behind
the metal cover marked with the safety label. Be especially careful when
working on the unit if this cover has been removed. Always replace
the cover when the service procedure is complete. Before making any
changes, disconnect the power supply to prevent electrical shock or
damage to the equipment. It may be necessary to turn off more than one
power supply disconnect.
All electrical wiring is to be done in accordance with local codes, or in the
absence of local codes, with: 1) The National Electrical Code ANSI/NFPA
No. 70 - latest Edition, or 2) CSA STD. C22.1 “Canadian Electrical Code
- Part 1.” This appliance must be electrically grounded in accordance
with these codes.
Hot Water -
This unit can produce water which is hotter than 125°F (52°C). This can
cause severe burns instantly or death from scalding. Always shut off the
system and allow it to cool for one hour before opening any pipe connec-
tions that may contain hot water.
Children, disabled and elderly persons are at the highest risk of being
scalded. See the Installation and Operating manual for instructions be-
fore setting the temperature at the NeoTherm unit.
For NTV units - Adjust the outlet control (limit) or use temperature limiting
valves to obtain a maximum water temperature of 125°F (52°C). Instruct
all users to feel the water temperature before getting into the bath or
shower.
The NeoTherm unit is protected against over-pressurization. A pressure
relief valve is included with each NeoTherm unit.
