Resumen del manual
For protection against excessive pressures and temperatures, local codes require the installation of a temperature-and-pressure (T&P) relief valve certified by a nationally recognized laboratory that maintains periodic inspection of production of listed equipment of materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff for Hot Water Supply Systems. ANSI Z21.22-1971. THE CUSTOMER IS RESPONSIBLE TO PROTECT PROPERTY AND PERSONNEL FROM HARM WHEN THE VALVE FUNCTIONS. All water heaters have a risk of leakage at some unpredictable time. IT IS THE CUSTOMER'S RESPONSIBILITY TO PROVIDE A CATCH PAN OR OTHER ADEQUATE MEANS, SO THAT THE RESULTANT FLOW OF WATER WILL NOT DAMAGE FURNISHINGS OR PROPERTY. WATER HEATER PLACEMENT 1. Place the heater on a solid foundation in a clean, dry location nearest to the point of hot water use. 2. The water heater should be protected from freezing and waterlines insulated to reduce energy and water waste. 3. Leave a minimum of 18” clearance for element withdrawal, if necessary. 4. Do not install in an area where flammable liquids or combustible vapors are present. PIPING INSTALLATION NOTE: The most effective means for preventing deterioration from accelerated corrosion due to galvanic and stray current is the installation of dielectric fittings/unions. The installation of these fittings is the responsibility of the installing contractor. 1. Connect the cold water inlet and hot water outlet to the appropriate connections as shown; refer to the drawing for location and sizes. 2. Install the combination temperature and pressure safety relief valve in the tapping provided. Note that this is required by law for safety considerations. Outlet to floor drain Install into provided tapping Manual Release Lever Temperature Probe Temperature Probe Temperature and Pressure Relief Valve 3. Install a relief valve overflow pipe to a nearby floor drain. CAUTION: No valve of any type should be installed between the relief valve and tank or in the drain line. FILLING THE HEATER 1. Open the pressure relief valve test lever to allow air to escape. 2. Open the valve to the cold water inlet and allow the heater and piping system to completely fill, as indicated by a steady flow of water from the relief valve. ELECTRICAL INSTALLATION 1. Enter electric enclosure with properly sized feeder leads. Single-phase installations require two (2) leads; three phase installations require three (3) leads. 2. Install these power leads into the box lugs on the terminal block or magnetic contactor. See wiring diagrams below. 3. Torque screws per torque chart included in Section VI. 4. All other electrical connections are made at the factory; therefore, no other electrical connections are necessary. THERMOSTAT SETTING (BULB AND CAPILLARY IMMERSION TYPE) The bulb and capillary type thermostat is immersed in a Type 316L stainless steel well in the storage vessel. The full thermostat range is 100-240°F, but should not be operated over 195°F. There is a setting screw, which can be locked at a particular setting to prevent an operator from turning the dial beyond a determined temperature point. To change the locking set screw open the thermostat cover and follow the printed directions on the inside of the cover. To change the operating temperature setting on the thermostat within the allowed range simply insert a screwdriver in the slot and make the appropriate adjustment to the temperature setting according to the desired point on the dial. FINAL CHECKS 1. Check all connections for tightness. 2. Ensure that all the above steps are completed 3. After the water is heated for the first time, monitor the water temperature as described in Section III, Quarterly Inspection. SECTION III - SCHEDULED MAINTENANCE AND OPERATION WARNING / CAUTION Before performing any maintenance procedure, make certain power supply is OFF and cannot accidentally be turned on. MAINTENANCE AND OPERATION The water heater is automatic in its operation. It will maintain a full tank of water at the temperature setting of the thermostat. The water heater should not be turned on without first making sure that the tank is full of water and that all air has been released. FREEZING The tank should be fully drained in the event the electricity has been turned off and if there is danger of freezing. QUARTERLY INSPECTION 1. Monitor thermostat a. Let water heater completely heat to a designated thermostat setting. b. After thermostat satisfies (that is, when the thermostat actually clicks off), draw water from heater. c. Compare water temperature of drawn water to the temperature setting of the thermostat when it satisfies. Normal variation between the two points is approximately + 5°F. d. If these two readings do not coincide within acceptable tolerances and verification has been made of the accuracy of the temperature-reading gauge, replace the thermostat. 2. Lift test lever on relief valve and let water run through valve for a period of appr...
