6- GENERAL OPERATING INSTRUCTIONS
Operating your new tankless water heater is similar to using any traditional water heating system. However,
HotMax endlessly produces near boiling hot water instantly without dropping in temperature over time so it is
very important that you carefully read all of the setup procedures and operating instructions and tips to ensure
the maximum performance and energy savings from your new water heater. We recommend that all members
of the household read these General Operating Instructions.
How your new water heater works:
Your tankless water heater does not store hot water like a conventional
tank-type water heater. It contains heating elements that are capable of heating water to near boiling
temperature on-demand. As soon as you turn on a hot water dispenser, a sophisticated flow sensor recognizes
that you have turned on the water. This sensor measures flow rate while another sensor measures the incoming
water temperature. This information is transmitted continually to the computer logic controls which decide how
much power to send to the heating elements to heat the water to your desired temperature. Once the water
dispenser is turned off your water heater will turn off as well.
WARNING
Scalding Hazard: The dispenser delivers near boiling 210°F (99°C) water which
can instantly burn or scald a person. Use care when operating this appliance.
NOTICE:
If HotMax is installed at high altitudes, water will boil at lower temperatures. Turn down
the set point on the heater to compensate for this high altitude.
Water Quality:
Quality of water should be taken into consideration when installing and maintaining the water
heater. Water conditions outside the recommended levels outlined below are not permitted and can damage
the water heater. Manufacture reserves the right to deny any warranty claim regarding damage suffered due to
use in water conditions not in accordance with the table below.
If water heater is installed in an area that is known to have hard water in excess of 10 Grains per gallon, which
may cause scale build-up, the water must be treated and/or the heater exchanger flushed regularly to prevent
damage to heat exchanger and/or heating elements.
A water treatment device such as a scale inhibitor or water softener should be installed on the cold water feed
to maintain optimal performance of the water heater in hard water areas. Contact customer service for
additional information on these accessory kits.
