For Installations in the State of California
California Law requires water heaters to be braced, anchored, or strapped to resist falling or horizontal displacement due to earthquake motion. Refer to the California Plumbing Code or specific local modifications.
Installation Instructions
Location
Locate the water heater in a clean, dry area as near as practical to the area of greatest water demand. Avoid locations prone to freezing temperatures or high humidity. Ensure adequate air circulation for optimal performance, especially for the heat pump component.
NOTICE: If air temperature in installed location drops more than 15°F (8°C) during heating, air circulation is insufficient for efficient operation. Utilize ducting to direct cold exhaust air to another location.
CAUTION: The water heater should NOT be located in an area where leakage of the tank or connections will cause damage to the adjacent room or in lower floors of the structure. Where such areas cannot be avoided, it is recommended that a suitable drain pan with adequate drainage be installed under the water heater.
NOTICE: Installation in a confined space will lead to higher power consumption if adequate ventilation is not provided.
Water Supply Connections
Install flexible connections on the hot and cold water connections for vibration isolation and ease of servicing. Connections are 3/4" NPT. Install a shut-off valve in the cold water line near the water heater.
NOTICE: DO NOT apply heat to the HOT or COLD water connections. If sweat connections are used, sweat tubing to adapter before fitting adapter to the water connections on heater. Any heat applied to the water supply fittings will permanently damage the dip tube and/or heat traps.
Thermal Expansion
In a "closed water system" (where a check valve or backflow prevention device is present), water expands when heated, creating pressure. This can lead to rapid pressure increases and potential damage to the relief valve or system. An expansion tank should be installed in the cold water line to control thermal expansion.
Condensate Drains
Consult local codes for condensate drain requirements. The unit has a 3/4" NPT female primary condensate connection. Use MIP fittings. Drain lines must be pitched downward at a minimum of 1/8" per foot and include a P-trap if connected to a sewer pipe. DO NOT allow condensate to drain into the water heater drain pan. Insulate drain lines where necessary to prevent sweating.
Relief Valve
A combination temperature and pressure (T&P) relief valve is factory installed and must remain in place. The pressure rating must not exceed 150 PSI. The btu/h rating must not be less than the water heater's input rating. The discharge line must be connected to a suitable open drain, pitched downward, and protected from freezing. No valve, restriction, or reducer coupling should be installed in the discharge line.
WARNING: DO NOT connect other plumbing to the T&P plumbing; it must go directly to a suitable open drain. DO NOT connect the T&P plumbing to the condensate plumbing.
Ducting Requirements
Always check local building and HVAC codes. Ducting configurations must comply with guidelines. Ducting must be adequately supported. UL Certified terminations are required for outdoor ducting. Indoor registers must be approved for HVAC applications. Use a short section of flexible duct (12 inches minimum) between the water heater and rigid ducting for noise and vibration isolation.
Considerations for duct system planning include running ducts directly, limiting elbows/bends, using the largest duct size possible, and considering termination placement to reduce recirculation.
| Duct Type / Diameter | 8" | 7" | 6" | 5" |
|---|---|---|---|---|
| Rigid | 340' | 160' | 65' | 17' |
| Flexible | 125' | 65' | 25' | -- |
Table 2 provides equivalent feet for duct accessories and reduced diameter terminations.
Electrical Connections
A separate branch circuit with copper conductors, overcurrent protective device, and suitable disconnecting means must be provided by a qualified electrician. All wiring must conform to local codes and the National Electrical Code ANSI/NFPA 70.
WARNING: Turn off electric power at the fuse box or service panel before making any electrical connections.
CAUTION: The presence of water in piping and water does not provide sufficient conduction for ground. Non-metallic piping, dielectric unions, flexible connectors can cause the water heater to be electrically isolated.
| SINGLE PHASE WIRING | Total Water Heater Wattage | Copper Circuit Size AWG (Based on NEC, Table 310.15(B)(16)) | Amperage Rating |
|---|---|---|---|
| 2200 | 15 | 14 | |
| 4200 | 15 | 14 | |
| 4600 | 20 | 12 | |
| 5600 | 25 | 10 | |
| 7400 | 30 | 10 | |
| 9000 | 35 | 8 |
NOTE: When using metal conduit and wire for current connections, an additional 1/4" size larger conductor is required. This will account for the increased amperage rating of the wire.
Insulation Blankets
Local codes may require external application of insulation blankets. Installation must comply with applicable energy conservation standards. Manufacturer's warranty may not cover damage or defects caused by installation, attachment, or use of energy saving or other unapproved devices.
CAUTION: If local codes require the application of an external insulation blanket to this water heater, pay careful attention to the following so as not to restrict the proper function and operation of the water heater.
- DO NOT cover the Controller Assembly, temperature and pressure relief valve or drain valve.
- Inspect the insulation blanket frequently.
Operating the Water Heater
Safety Precautions
- Disconnect all power to water heater if it has been subjected to overheating, fire, flood, physical damage.
- DO NOT turn on water heater unless it is filled with water.
- DO NOT turn on water heater if cold water supply shut-off valve is closed.
- If there is any difficulty in understanding or following the Operating Instructions or the Care and Cleaning section, it is recommended that a qualified person or serviceman perform the work.
CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipe as the water begins to flow. DO NOT smoke or use an open flame near the faucet at the time it is open.
WARNING: If the water heater has been subjected to fire, flood or physical damage, disconnect all power to water heater, and DO NOT operate the water heater again until it has been checked by a qualified service technician.
NOTICE: DO NOT use this appliance if any part has been under water. Immediately call a qualified installer or service agency to replace a flooded water heater. DO NOT attempt to repair the unit! It must be replaced.
DANGER: There is a hot water scald potential if the thermostat is set too high. Households with small children, disabled, or elderly persons may require a 120°F (49°C) or lower thermostat setting to prevent contact with HOT water.
Safety Controls
The water heater is equipped with a temperature limiting control (ECO) that will shut off power to the heating element if the water temperature becomes excessively high. The ECO must be reset manually.
CAUTION: The cause of the high temperature condition must be investigated by a qualified service technician and corrective action must be taken before placing the water heater in service again.
Water Temperature Setting
The water temperature can be regulated via the control display. Safety and energy conservation are key factors. Lowering the temperature setting saves energy and operating costs. Factory setting is 120°F (49°C) or less, as required by local codes.
Water temperatures above 125°F (52°C) can cause severe burns or death from scalding.
Mixing valves are recommended for reducing point-of-use water temperature.

Care and Cleaning
Draining the Water Heater
CAUTION: Shut off power to the water heater before draining.
To drain, open a hot water faucet, then turn off the cold water supply. Attach a garden hose to the drain valve and open the valve. Open the relief valve to allow air into the tank.
DANGER: Before manually operating the relief valve, make certain no one will be exposed to the danger of scalding if the water released by the valve is hot enough to present a scald hazard.
NOTICE: If the temperature and pressure relief valve discharges periodically, it may be due to a thermal expansion in a closed water system. Contact your supplier or your plumbing contractor to learn how to correct this. DO NOT plug the relief valve outlet.
Routine Preventative Maintenance
Properly maintained, your water heater will provide years of dependable, trouble-free service. A routine preventative maintenance program should be established and followed.
Most electrical appliances, even when new, make some sound during operation. If the hissing or singing sound level increases excessively, contact a qualified installer or plumbing contractor.
IMPORTANT: See "DANGER on left". At least once a year, lift the lever on the temperature and pressure relief valve located on the side of the water heater to make certain the valve operates freely. Flush several gallons to open drain.
It is recommended to clean the filter on the heat pump's "Clean Filter reminder" alert. Wash with mild detergent and dry. Replace the filter as needed.
Water tanks can act as a setting basin for solids suspended in the water. It is therefore recommended that about two quarts of water be drained from the water heater's drain tank each month to clean the tank of these deposits.
Rapid closing of faucets or solenoid valves in automatic water using appliances can cause banging noise. Hear in a water pipe. Strategic placement of the water heater system or water hammer arresting devices can be used to minimize the problem.
Vacation and Extended Shut-Down
If the water heater is to remain idle for an extended period, turn off power and water to conserve energy and prevent hydrogen gas build-up. Drain the water heater and piping if freezing temperatures are expected.
After a long shutdown, check the water heater's operation and controls by qualified service personnel. Ensure the water heater is completely filled before placing it back into operation.
Anode Rod
The anode rod is designed to prolong the life of the glass-lined tank by slowly consuming itself, thereby preventing corrosion. Water with high sulfate or mineral content can produce a hydrogen sulfide or rotten egg odor. Chlorination of the water supply should minimize this problem.
NOTICE: DO NOT remove the anode rod from the water heater's tank. Operation with the anode rod removed will greatly shorten the life of the glass-lined tank and will exclude warranty coverage.
