GENERAL SAFETY INFORMATION |
PRECAUTIONS |
|
HYDROGEN GAS (FLAMMABLE) |
DO NOT USE THIS WATER HEATER IF ANY PART HAS BEEN EXPOSED TO FLOODING OR WATER DAMAGE. Immediately call a qualified service technician to inspect the water heater and to replace any part of the control system which has been under water.
If the unit is exposed to the following, do not operate heater until all corrective steps have been made by a qualified service technician.
1.External fire.
2.Damage.
3.Firing without water.
GROUNDING INSTRUCTIONS
This water heater must be grounded in accordance with the National Electrical Code and/or local codes. These must be followed in all cases.
This water heater must be connected to a grounded metal, permanent wiring system; or an equipment grounding conductor must be run with the circuit conductors and connected to the equipment grounding terminal or lead on the water heater.
Hydrogen gas can be produced in a hot water system served by this heater that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To reduce the risk of injury under these conditions, 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 probably be an unusual sound such as air escaping through the pipe as the water begins to flow. THERE SHOULD BE NO SMOKING OR OPEN FLAME NEAR THE FAUCET AT THE TIME IT IS OPEN.
When servicing this unit, verify the power to the unit is turned off prior to opening the control cabinet door.
Read and understand this instruction manual and the safety messages herein before installing, operating or servicing this water heater.
Failure to follow these instructions and safety messages could result in death or serious injury.
This manual must remain with the water heater.
CAUTION
Improper installation, use and service may result in property damage.
•Do not operate water heater if exposed to flooding or water damage.
•Inspect anode rods regularly, replace if damaged.
•Install in location with drainage.
•Fill tank with water before operation.
•Properly sized thermal expansion tanks are required on all closed water systems.
Refer to this manual for installation and service.
Explosion Hazard
Flammable hydrogen gases may be present.
Keep all ignition sources away from faucet when turning on hot water.
Electrical Shock Hazard
•Turn off power at the branch circuit breaker serving the water heater before performing any service.
•Label all wires prior to disconnecting when performing service. Wiring errors can cause improper and dangerous operation.
•Verify proper operation after servicing.
•Failure to follow these instructions can result in personal injury or death.
Water temperature over 125°F (52°C) can cause severe burns instantly resulting in severe injury or death.
Children, the elderly and the physically or mentally disabled are at highest risk for scald injury.
Feel water before bathing or showering.
Temperature limiting devices such as mixing valves must be installed when required by codes and to ensure safe temperatures at fixtures.
Explosion Hazard
Overheated water can cause water tank explosion.
Properly sized temperature and pressure relief valve must be installed in the opening provided.

Recovery capacities at 100° F rise equal: for non-simultaneous element operation = 4.1 gal. x KW of one element; for simultaneous element operation = 4.1 gal. x 2/3 KW of both elements. For other rises multiply element KW as previously explained by 4.1 and divide by temperature rise. Full load current for single phase = total watts : voltage.
