PLUMBING CONNECTIONS
ATTENTION
1. It is recommended that this water heater be installed by a licensed and qualified plumber in
accordance with all applicable national, state, and local plumbing codes.
2. Make sure there are no impurities in the waterway. It is recommended to install a water softener
to prevent the water heater from scaling, which can effectively prolong the service life.
3. Turn on the water source and let the water flow through the water heater for at least 2 to 3 minutes.
This will remove air from the unit and prevent the water heater from scaling during use. This must
be done before powering on the device. Otherwise, the heating element will be severely damaged.
4. When you connect the pipes to the unit, use a wrench to hold the connection point of the unit and
use another wrench to tighten the flexible water hose to the hot water unit. Over tightening must
be avoided.
5. It is recommended to install a manual shut-off valve (not provided) at the inlet water connection of
the water heater to allow for easy shut-off if future maintenance or service is needed.
6. This product does not use a storage tank to maintain hot water, therefore a temperature-pressure
relief valve is not required for most installations.
7. It is required to use 1/2"NPT water connections for the EVT-14K connections.
8. Never use PVC on the hot water outlet. Use CPVC or other high-temperature-rated materials.
