“AIR” IN HOT WATER FAUCETS

A

warning

Explosion Hazard

Flammable

hydrogen

gases may be present.

Keep all Ignition sources
away from faucet when

turning on hot water.

HYDROGEN GAS: Hydrogen gas can be produced in a hot

water system that has not been used for a long period of time

(generally two weeks or more). Hydrogen gas is extremely

flammable and explosive. To prevent the possibility of injury

under these conditions, we recommend the hot water faucet
be opened for several minutes at the kitchen sink before any
electrical appliances which are connected to the hot water
system are used (such as a dishwasher or washing machine).

If hydrogen gas is present, there will probably be an unusual

sound similar to air escaping through the pipe as the hot water
faucet is opened. There must be no smoking or open flame near
the faucet at the time it is open.

RUMBLING NOISE

In some water areas, scale or mineral deposits will build up on

your heating elements. This buildup will cause a rumbling noise.

Follow Element Removal/Replacement instructions to clean and
replace the elements.

HIGH TEMPERATURE SHUT OFF SYSTEM

This water heater is designed to automatically shut-off in the
event that the water temperature exceeds 190°F or 87.8°C.
A temperature limit switch or ECO (Energy Cut Off) is used
to shut off the power to the system if the water temperature
exceeds 190°F or 87.8°C (See “Water Temperature Regulation”
section). To reset the ECO disconnect power at the circuit
breaker/fuse box then remove the upper access panel. Reset
the ECO by firmly pushing in the red reset button located on the

ECO block. If the ECO continues to shut-off the water heater
contact a qualified person for service.

DIAGNOSTIC CODES

If a fault is detected by the system, an error message will be

displayed on the MAIN screen indicating the general nature
of the fault. More detailed fault information can be obtained
by viewing the MAINTENANCE screen. The MAINTENANCE
screen is accessed by simultaneously actuating the UP and

DOWN arrows on the user interface touch pad for 3 seconds.
(Note: engaging the child lock feature will not prevent access

to the MAINTENANCE screen, but will prevent inadvertent
changing of the set point temperature.) Once the screen
changes to MAINTENANCE, use the up arrow to scroll to
the error messages. There are six (6) system temperature

messages display in succession, followed by four (4) stored

fault messages. Fault messages are stored newest to oldest

and are labeled E01 - E04. Utilize the DIAGNOSTIC CODES
table for explanation of what each fault message means and
corrective action steps for each.”

the preceding paragraph. Scroll through the parameters using
the UP and DOWN arrows. The six (6) system temperatures
are listed in the following order:

AMBIENT TEMPERATURE

TANK TEMPERATURE (average)

UPPER TANK TEMPERATURE

LOWER TANK TEMPERATURE

DISCHARGE TEMPERATURE (compressor discharge)

COIL TEMPERATURE (evaporator coil outlet)
