1. WELL WATER INSTALLATIONS
Due to the fluctuation in water pressure when using on a well water system, users may experience fluctuations in
water temperature. Fluctuations can be rectified with use of a water pressure regulator. When using a well system
with a pump switch set to 40-60PSI, it is best to set your water pressure regulator at 45PSI. Alternatively, if using
a pump switch set to 30-50PSI, it is recommended to set your water pressure regulator at 35PSI.
2. BASEMENT INSTALLATIONS IN COLD WEATHER CLIMATES
The EZ Deluxe does not come provided with freeze protection. If exposed to freezing temperatures, the water
in the heat exchanger can freeze and can damage the pipework within the heat exchanger. When performing a
basement wall installation, it is recommended to install on a sub-frame (e.g 2x4) to create a air buffer between
the wall and the back of the unit. This is to reduce risk of freezing through direct contact with basement walls.
Typically basement walls are poorly insulated & thus surface temperatures can be much colder than the ambient
room air.
3. MIXING VALVES
Modern mixing valves use a thermostatic temperature valve to control hot and cold water to faucets,
showerheads, and tub fixtures. These devices can often cause an issue when used in conjunction with a tankless
water heater set at a high temperature. When water temp is set above 110-120F, these valves will add cold water
to adjust the temperature to keep from scalding. An unwanted effect of this is that the hot water flow may drop
below required levels to keep the heater running. There are a number of recommendations to reduce the risk:
a. Lower the water temperature setting on the water heater. Suggested settings of approx. 42C are ideal in
many scenarios.
b. Adjust the temperature setting on the mixing valve. (See manual for each individual fixture.)
c. Replace showerhead with a high flow rate showerhead. It is common for a mixing valve fixture used in
conjunction with a water saving showerhead to cause ignition issues with most tankless water heaters.
Be sure to use a showerhead with at least a 2GPM flow rate in conjunction with a mixing valve fixture
to limit issues.
4. USE A SURGE PROTECTOR
The EZ Deluxe uses many sensors that are based on resistors. It is important to protect the electronics of the EZ
Deluxe system by plugging the units power cord into a surge protector.
