LOCATING THE NEW WATER HEATER Facts to Consider About the Location to a drain. However, unanticipated damage can be reduced or prevented by a leak detector or water shut-off device used in conjunction with a piped drain pan. These devices are available from some plumbing supply wholesalers and retailers, and detect and react to leakage in various ways: • Sensors mounted in the drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected.
iNSTALLATION Required Ability Contaminated Water Installation and service of this water heater requires ability equivalent to that of a qualified installer or service agency (page 2) in the field involved. Plumbing and electrical work is required. This water heater shall not be connected to any heating system(s) or component(s) used with a non-potable water heating appliance. Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system.
paragraph. The new valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater Btu/hr or KW input rate as shown on the water heater’s model rating plate. For safe operation of the water heater, the temperature and pressure relief valve must not be removed from its designated opening nor plugged.
electrical This is an example of calculating heater amperage for both types of element operation. From this, the branch circuit conductor and overcurrent protection sizing can be established. The example is of a three-phase 240 volt unit with two, 6 kw elements. The notations are for units field converted to single-phase. Check the heater model and rating plate for actual specifications and substitute those values in the following.

OPERATION General Initial Start Up Refer to the Features and Components section of this manual (page 7) for the location of components mentioned in the instructions that follow. The following checks should be made by the installer when the heater is placed into operation for the first time. NEVER turn on power to the water heater without being certain the water heater is filled with water and a temperature and pressure relief valve is installed in the relief valve opening. 2.
TEMPERATURE REGULATION approximately the 140°F (60°C) setting. The over temperature device (ECO high limit) attached to each thermostat has a manual reset. MODEL WH10C 40A 120-277 VAC 25A.480-600 VAC 125VA.PT.DTY. 120-480 VAC MED APCOM INC 30A 120-250 VAC 22A 277 VAC 12.5A 480-600VAC 125 VA.PT.DTY. 120-480 VAC THE WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE THERMOSTAT TO CONTROL WATER TEMPERATURE.
MAINTENANCE General Anode Rod Inspection The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding tank, water ions attack and eat away the anode rod. This does not affect water’s taste or color. The rod must be maintained to keep tank in operating condition. Periodically the drain valve should be opened and the water allowed to run until it flows clean.
TROUBLESHOOTING CHECKLIST Checklist ABNORMAL SOUNDS Before calling for service, check the following points to see if the cause of trouble can be identified and corrected. 1. Sediment or lime scale accumulations on the elements causes sizzling and hissing noises when the heater is operating. • The sounds are normal, however, the tank bottom and elements should be cleaned. See the Maintenance section of this manual.
Leakage Checkpoints Instructions: Use this illustration as a guide when checking for sources of water leakage. You or your dealer may be able to correct what appears to be a problem. NOTE: Cover and Insulation shown removed to reveal tank top. Where possible remove or lift top cover to examine threads of fittings installed into tank for evidence of leakage. Correct fitting leaks as necessary. Relief Valve Condensation and dripping may appear on pipes when cold water temperature is low.
