LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 1.) INSTALLATION INSTRUCTIONS LITTLE GIANT “LG-SERIES” The Electro-Steam Generator design consists essentially of a high pressure chamber filled with water that is heated by one or more submerged resistance type electric heating elements. Automatic controls are provided to maintain the pre-set operating pressure and water level.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 2.) OPERATION & SEQUENCE OF EVENTS IMPORTANT – READ INSTALLATION INSTRUCTIONS BEFORE OPERATING 1. Turn on water supply from the source to the Generator. 2. OPEN all valves on the Generator except for the Manual Drain (#19). 3. Place main disconnect switch in ON position. 4. Place ON/OFF Switch (#2) in ON position. 5. • The Water Solenoid (#7) [and Pump (#8), if high pressure] will engage and the chamber will begin to fill with water.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 3.) CLEANING & MAINTENANCE The following cleaning procedures are HIGHLY RECOMMENDED in order to keep your Steam Generator in the best operating condition at all times. 3.1) MANUAL “BLOW DOWN” A Manual “Blow Down” is an easy way to GREATLY extend the life of your Steam Generator. Using a Motorized Auto-Flush & Drain (MAFD) of course helps, but is not a “Cure all”.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 3.2) CLEANING WATER LEVEL PROBES (Continued) 6. 7. 8. 9. Clean probes to remove rust and scaling. NOTE: To clean probes you may use wire wheel, wire brush, steal wool, or Scotch-Brite. (Wire wheel works the best) You may also want to try some sort of chemical like CLR remover or LIME-A-WAY. Reinstall probes assuring each probe’s length is assigned to its proper letter.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 3.4) REPLACING GLASS GAUGE & RUBBER WASHERS OR GLASS PACKINGS The Sight Glass (#10) gives the operator the ability to easily monitor the actual water level inside the chamber. If the Sight Glass (#10) gets clogged or is no longer functional, it can be very difficult to troubleshoot a problem. 3.4.

LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 3.5) CHAMBER CHEMICAL/ACID TREATMENT All Electric Steam Generator should be cleaned regularly. The following is the least amount of times recommended to clean out your chamber: NORMAL WATER AREAS – Should be done ONCE A YEAR. BAD WATER AREAS – Should be done TWICE A YEAR.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 3.5) CHAMBER CHEMICAL/ACID TREATMENT (Continued) 4. Close Manual Drain (#19) and Steam Out (#16); turn generator on until Sight Glass (#10) shows that it is 1/2 full, and then shut off. 5. Insert funnel into coupling, where Safety Valve (#18) used to be. 6. Pour a 1/2 Gallon of hydrochloric acid (inhibited) solution (NON-FOOD APPLICATIONS) into funnel very slowly, being careful of fumes and venting while pouring.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 3.6) PRESSURE CONTROL DATA SHEET DEFINITIONS: “CONTROL” PRESSURE CONTROL – This pressure control should be the only one controlling the operating pressure of the generator. “SAFETY” PRESSURE CONTROL – This pressure control is only used if the “Control” fails. It is always set higher than the “Control”; if the operating pressure is passed, The “Safety” will turn the heaters off.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 3.7) SETTING THE PRESSURE CONTROLS SETTING PRESSURE CONTROLS INSTUCTIONS: WARNING – The pressure controls must be set while all circuits are live. TO AVOID ELECTRICAL SHOCK, DO NOT TOUCH the wires or the terminals in which they connect while setting the pressure controls. NOTES: - Setting the pressure controls greatly relies on your ability to tell whether the contactor(s) are turning the heaters on or off.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 3.7) SETTING THE PRESSURE CONTROLS (Continued) 5. At this point the contactor(s) should be clicked off and you should be able to click them on and then off again by pressing the SAFETY RESET. This is a way to test if the “SAFETY” is still controlling the pressure, and not the “CONTROL”.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 4.) CALCULATIONS AND DATA SHEETS 4.1) HEATER POWER & VOLTAGE RATINGS LG Model units use 3 Heaters to meet the required (KW) POWER from the customer’s specified INPUT VOLTAGE. Each heater comes in 5 different (KW) POWER RATINGS and 4 different VOLTAGE RATINGS. AVAILABLE HEATER RATINGS KW 3.33 5.00 6.50 8.33 9.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 4.3) AMPERAGE CALCULATIONS The INPUT VOLTAGE, PHASE, TOTAL POWER RATING, and HEATER VOLTAGE RATING are used to calculate the amperage. NOTE: 380-425V heaters are not usually rated for 380-425V. They are usually 208-240V heaters that have been re-stamped 380-425V and wired in series.
LG-10 thru LG-30 - User Manual Electro-Steam Generator Corp. 4.4) ACTUAL POWER RATING CALCULATIONS Because the HEATER VOLTAGE RATINGS only come in 4 different voltages, and there are so many different voltages in the field, the TOTAL POWER RATING is only completely accurate if the VOLTAGE IN is exactly equal to the HEATER VOLTAGE RATING. This means, in most cases, the TOTAL POWER RATING is not completely accurate. The AMERAGE and INPUT VOLTAGE can be used to calculate the ACTUAL POWER RATING.
