Section 8: Plumbing System
For normal operation:
1.
Turn on the power. The panel will light and display the current temperature at the inlet
of the unit.
2.
Press a temperature selection arrow (up or down) to see the current set temperature.
3.
Adjust the set temperature to your preference.
4.
Turn on a faucet.
It is dangerous to operate a Tankless Water Heater unattended. This may occur
accidentally if a sufficient leak develops in the water system or if a faucet is
left open. The tankless water heater will automatically turn off after operating
for 20 minutes and displays Error "En" on the Display.
Winterization
Freezing of the water heater and its plumbing components will result in severe damage not
covered by warranty Follow the recommendation(s) below if the unit is to be stored in a
freezing environment for a long period of time. At the start of the winter season or before
traveling to a location where freezing conditions are likely, the unit must be winterized.
The very small amount of water present in the heat exchanger DOES NOT require the in-
stallation of a bypass kit. Refer to the Winterization section for details..
Outside Shower
A handheld shower assembly with both hot and cold water is included for use outside of
your recreational vehicle. It may be located in a separate outside shower compartment
or at the utility center (if so equipped).
Be sure the water heater is ON and had sufficient time to heat the water.
1.
2.
If dry camping, be sure the 12-volt water pump is ON.
3.
Remove the handheld shower from its holder.
4.
Turn ON the hot and cold faucet knobs, and adjust the water temperature as desired.
5.
To activate the handheld shower turn ON the sprayer head attachment (some models).
To turn off the water, always close the hot/cold control (faucet) knobs. The lever on the
shower head will not completely stop the flow of water; this is intentional to allow for drain-
ing. After the water has been allowed to drain from the shower head, return it to the outside
shower storage. Any remaining water in the shower hose will drip or run out; this is not a
leak but performs as intended. If you are dry camping, turn the water pump OFF.
Turning off the water with the shower head lever can also create a condition where the hot
and cold water will mix through the outside shower faucet, thereby reducing the temperature
of the hot water. It can appear as though the hot water heater is not working properly.
™ NOTE: The shower head may be removed from the hose so that it will drain
faster. If you remove the shower head, be sure to reassemble it prior to stor-
age.
™ NOTE: When putting the shower assembly back into the storage compart-
ment, make sure the hose is not pinched or the shower head is positioned in a
way it can be damaged.
Faucets
The bathroom, kitchen and outside shower faucets operate much the same way as the faucets
in your home. Make sure there is sufficient water available and the 12-volt water pump is
turned ON before operating.
