Operation, Maintenance | Chromalox GSL3 specs

OPERATION

1.Do not operate heater at voltages in excess of that stamped on the heater since excess voltage will shorten heater life.

2.Always maintain a minimum of 2” of solution above the heated portion of the element to prevent exposure of the effective heated length. If the heater is not properly submerged, it may overheat, create a hazard of fire and shorten heater life. Do not operate heater if dry.

3.Sludge should not be allowed to build-up to the point where it contacts heater, as this can lead to premature heater failure. Sludge legs are standard on L-shaped heaters. Heater must not be operated in sludge.

MAINTENANCE

ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property dam- age. Heater must be installed by a qualified per- son in accordance with the National Electrical Code, NFPA 70.

1.Heaters should be checked periodically for coating and corrosion buildup and cleaned if necessary.

2.Tank should be checked regularly for sediment around the ele- ments, as sediment can act as an insulator and shorten heater life.

3.Check for loose terminal connections.

4.If corrosion or moisture is indicated in the terminal housing, check the conduit layout to correct the conditions that allow cor- rosion or moisture to enter the terminal housing.

THERMAL FUSE INSTALLATION/REPLACEMENT

The Thermal fuse device must be properly installed and these procedures followed or heater failure or fire may result.

A liquid level control is a must as an additional safety feature to help minimize the possibility of fire.

1.Make sure all electrical power to the heater is shut-off.

2.Unscrew the head cover. Remove the wire nuts from the fuse leads and save for re-use.

3.Remove the “Sealing Putty” and pull the Thermal fuse out of its well. Clean the “putty” out of the well and save for re-use.

4.Check the Thermal fuse and the inside of the well to see if it is wet. If wet inside, dry out well. Immerse the tube into the solu- tion. If moisture appears again inside the well DO NOT use the heater! Call the factory for further advice.

5.If the removed Thermal fuse is dry, proceed by using it as a guide to cut and strip the wires of the new Thermal fuse.

6.Re-connect the Thermal fuse leads to the extension leads using the original wire nuts.

7.Re-insert the Thermal fuse into the well making sure it is “fully seated” to the bottom of the well.

8.Re-seal using the original “sealing putty” or an RTV type sealant.

9.Replace the head cover, return the heater to the tank.

10.Turn the power back on.

Thermal Fuse Temperature System —

Be sure and satisfied that your process bath tanks are as well protected as possible from tank leaks, excessive evaporation, tank refill failures, and worker error.

Grounded Electric Immersion Heaters are practical, efficient and safe when used properly and installed in tanks that have prop- er solution levels, good ventilation, trained operators and safe- guards such as liquid level controls and Thermal fuse over-tem- perature sensors.

Thermal fuse systems help reduce the hazards created by low liquid levels and when properly seated and wired, they will cut off the power to the heaters, thus avoiding the extreme tempera- tures resulting if solution levels are low enough to expose heater hot zones.

Single Use Fuse (F) —

Sensor consists of a one-time thermal fuse which is standard on all GS and GT over-the-side heaters.

The F thermal fuse is wired in series with the controller. To operate properly the fuse must be fully seated to the bottom of the thermowell tube. When the fuse “blows”, shut off the main power to the heater, remove the spent fuse and install the new fuse. Refill the tank to proper level prior to turning power back on. Replacement thermal devices must be purchased from Chromalox.

Resettable Fuse (RF) —

Sensor consists of a Bi-metallic thermostatic sensor, an audi- ble alarm, alarm relay, and reset button.

The RF System operates on the same principle as the F except that the sensor does not “blow”. It operates as a Bi-metal- lic thermostat which “opens” and sounds the alarm. The reset but- ton must be pushed to re-activate the heater and control, after the solution level in the tank has been raised to the proper level.

FIRE/SHOCK HAZARD: Before replacing fuse, make sure the cause of the “failure” has been detected and corrected.
