LYNC Q WATER HEATER OPERATION
11.1 Temperature and Pressure Relief Valve(s)
A Temperature and Pressure Relief Valve(s) sized in accordance with ASME Boiler and
Pressure Vessel Code, Section IV HLW is installed in the tank.
W A R N I N G !
Secure relief valve discharge pipe to a suitable floor drain so hot water does not splash during
discharge. Hot water discharge can result in property damage, personal injury or death.
•
Follow the temperature and pressure relief valve manufacturer’s installation instructions
and all local, regional and national codes applicable to temperature and pressure relief
valve installation and discharge piping.
•
The relief valve discharge pipe must not be smaller than the relief valve opening and must
be secured to prevent it from lifting out of the drain under discharge pressure and must be
routed to allow complete drainage of the valve and line.
•
Do not plug the relief valves or install a reducing coupling, valve or other restriction in the
relief valves discharge lines, as this will eliminate the critical water temperature and
pressure protection it provides.
•
Thermal Expansion - A relief valve that periodically discharges may result from thermal
expansion if Element is installed in a system closed by components, such as a backflow
preventer or check valve in the cold water supply. These systems must be provided with
means to control expansion. Contact a water heater or plumbing professional to resolve
this situation.
W A R N I N G !
Do not plug relief valve(s), use discharge piping smaller than valve opening, or install a
reducing coupling, valve or other restriction in the relief valve discharge line. Failure to comply
with these requirements can prevent the relief valve from providing its intended temperature
and pressure protection, which may result in a sudden loss of pressure containment that can
cause property damage, exposure to hazardous materials, personal injury or death.
11.2 Electronic Low Water Cut-Off
When the water level is above the electrode position in the tank, pushing the RESET button will
energize the control (LED will be lit). The control remains energized until the water level drops
below the electrode position (LED will not be lit). Unless otherwise specified, there is a three-
second time delay on decreasing water level. Water level must be below tank probe location for
full three seconds before control de-energizes. In the event that a low water condition occurs, a
failure message will be displayed on the controller touch-screen. This failure lockout can be
reset by pressing the LWCO RESET button located on the front control panel. Once the LWCO
control board has been reset, the Main Reset button located on the front control panel can be
reset as well.
The Electronic Low Water Cut-Off probe is located in the top head of each Element.
