3. Selecting an Installation Location
• This Water Heater is designed for indoor installation only.
• It should not be installed in a location where it might be subjected to freezing temperatures as the freezing of
the water in the Water Heater can lead to severe and irreversible damages which are not covered under your
warranty.
• The Water Heater should not be placed in a location that is difficult to access.
•
Ensure that the water heater, as well as the power supplies and water connections, are out of reach of
children as the outlet water pipe can get very hot and touching can lead to injury.
• Avoid installing your tankless water heater in a location prone to excessive humidity, moisture, or dust, or in an
area where it may be splashed with water or other liquids. DO NOT install underwater pipes or air conditioning
lines that might leak or condense moisture that could then drip onto the heater. DO NOT install above electrical
boxes or junctions.
• Do not install in areas which can be damaged due to leakage from the Water Heater. However, safety measure
such as suitable drip pan or an active water leak detector and shutoff valve should be installed in such areas
that cannot be avoided.

4. Mounting Your Water Heater
1.
Your tankless water heater should be secured to a solid mounting surface with four screws, (minimum 1"
(25.4mm) long).
2.
Ensure that the unit is level before fastening the screws in place.
3.
The unit must be installed in an upright position with the water inlet and outlet at the bottom of the unit. Do not
install inversely with connections facing up or sideways with connections facing right or left.
4.
Do not install the unit above electrical boxes or junctions.
5.
The water heater must be installed in a manner that prevents contact with flammable liquids and gases. Keep
these flammable materials at least two feet away from the heater and the hot water outlet pipe. The water heater
and the hot water outlet pipe must be secured, and out of children's reach to prevent tampering with controls or
contact with an extremely hot pipe.
6.
If installing the heater on an upper floor or attic, make sure installation complies with the local codes. Install a drip
pan with drainage, or a leak detector and automatic shutoff valve, to prevent damage in case of any leakage.
