 Smart Technology Digital Controller and Display---This is what has improved the tankless water heater design by automatically increasing or decreasing energy consumption based on the inlet water temperature and flow rate of water. The revolutionary patent pending Smart Technology Digital Controller is unique to our units and cannot be found on any other tankless be it electric or gas.
When a hot water faucet is turned on and the water begins to flow, a sophisticated flow sensor detects that hot water is being demanded and turns the water heater on. Instantaneously, a series of sensors gather information about the flow rate of the water and the incoming water temperature. This information is sent to a microprocessor which calculates the amount of power needed to heat the water to the temperature set point. The water flows across the internal heating elements and exits the unit at the desired temperature. The startup process takes a couple of seconds. A convenient thermostatic control and digital display on the front of the unit allows the homeowner to select an output temperature of between 80 and 125 degrees F.
The sensors continue to monitor the water flow rate and incoming water temperature as long as the water is running. They send constant and continuous data to the microprocessor so power to the heating elements can be modulated in accordance with changes in incoming flow rate and temperature. If, for instance, the flow rate increases because a second demand for hot water in the home is initiated, the unit will increase its power output to maintain a consistent and precise output temperature.
The tankless water heater will remain on until the hot water faucet is closed. As soon as the flow sensor detects that water has stopped flowing, the power to the unit is completely turned off.
All GULFWAVE 2 tankless water heaters are manufactured in the USA with quality North American components. Each GULFWAVE 2 tankless water heater must pass a rigorous three phase testing and inspection process prior to shipment.
Pressure Integrity Test
Each unit is pressure tested at 180 PSI to insure against leaks. This is over 3.5 times the water pressure that the unit will experience in a typical residential installation. Please see the internal view of the GULFWAVE 2 on the Product page. All of the models utilize the same parts and technology, but have varying sizes and numbers of heating elements.
Electrical Integrity Test
Each unit is connected to a special testing module that sends a 1,000 volt current surging through the unit for one millisecond to verify that there are no short circuits and that the unit’s circuitry is properly configured.
Specifications Level Test
Each unit is temporarily attached to a testing station that duplicates the conditions present in a typical installation. The unit is turned on and the temperature of the water produced by the unit is measured at several flow rates to insure that the proper temperature rise specifications are met and that the unit self-regulates with the varying flow rates. |

INSTALLATION
|
| |
| What do you get with the purchase of a unit? The system is supplied with a sub panel, complete with its breakers and water heater flexible hoses with compression fittings for ease of installation. |

|
As with all electrical appliances, under no circumstances should you attempt to install, repair or disassemble the tankless water heater without first shutting off all power to the unit directly at the fuse or breaker box.
- Installation of this product is restricted to indoor locations only by licensed plumbing and electrical contractors.
- TURN OFF ALL POWER to the water heater directly at the fuse or breaker box.
- PLUMBING CONNECTIONS: BEFORE connecting the water heater lines to the water heater, it is extremely important to FLUSH the lines to eliminate all plumbing paste or electrical residues or any other type of residue in the lines.
This water heater is supplied with water heater hoses. Bring the HOT WATER and COLD WATER lines to the water heater hoses and attach the lines to the proper fittings.
- Connect the COLD water line to the water heater hose inlet marked “COLD WATER IN” (right hand pipe).
- Connect the HOT water line to the water heater hose outlet marked “HOT WATER OUT” (left hand pipe).
- After tightening hoses, open the hot water faucet and allow the water to run through the water heater for a least TWO MINUTES. This process clears all the air from the lines and MUST be performed prior to turning on the power to the unit.
FAILURE TO FOLLOW THIS STEP WILL CAUSE PERMANENT DAMAGE TO THE UNIT AND WILL VOID THE WARRANTY
A pressure relief valve is not required for this water heater. You can, however, install one as an added safety feature if your city or state codes require it.

ELECTRICAL CONNECTIONS:
|
| |
| All models require high temperature wire and specific size breakers as follows: |
| |
 |
| |
|
Wire size may vary depending on local electrical standards. For best results, use solid copper wire. The electrical specifications are based on 208-240 volts, single phase. This unit may not be installed on three phase electrical systems. All units are supplied with power leads, service disconnect box and breakers.
- DOUBLE CHECK the electrical connections to make sure all leads and ground have been properly attached to the terminals of the service disconnect box.
- Finally, turn power to the heater on at the fuse or breaker box and enjoy an endless supple of hot water, plus space and energy savings for years to come. CAUTION – Do not touch any part of the interior of the unit with any object once the power is turned on to the unit. A short will incapacitate the unit.
- The Digital Control can be set to customize the water temperature to the user’s preference. We suggest for economy any safety reasons that the unit be adjusted to allow the person who takes the hottest showers in the home to be comfortable with the mixer valve at the highest heat setting. This eliminates the need to mix cold water with hot water, thereby reducing energy costs. It also eliminates scalding injuries. Once adjusted the water temperature maintains the same adjustment.
