SAFETY SAFETY FIRST General Safety Statements The GSI Group Incs Principal concern is your safety and the safety of others associated with grain handling equipment. We want to keep you as a customer. This manual is to help you understand safe operating procedures and some problems which may be encountered by the operator and other personnel.
SAFETY Electric Heater Roof Damage Warning And Disclaimer GSI DOES NOT WARRANT ANY ROOF DAMAGE CAUSED BY EXCESSIVE VACUUM OR INTERNAL PRESSURE FROM FANS OR OTHER AIR MOVING SYSTEMS. ADEQUATE VENTILATION AND/OR "MAKEUP AIR" DEVICES SHOULD BE PROVIDED FOR ALL POWERED AIR HANDLING SYSTEMS. GSI DOES NOT RECOMMEND THE USE OF DOWNWARD FLOW SYSTEMS (SUCTION). SEVERE ROOF DAMAGE CAN RESULT FROM ANY BLOCKAGE OF AIR PASSAGES.
INSTALLATION Checklist Before Installing Electric Heater 1. One of the most important factors for installation is providing adequate power to run the unit. Under sized wire can lead to voltage drop and can cause overheating of power leads and poor performance. Therefore, it is necessary to know the distance from the unit to an available trans former and the horsepower of your fan unit. These two factors will determine the size of wire needed for efficient operation.

INSTALLATION Electric Heater Downwind Heater Electrical Installation Be Sure Power Is Disconnected And Locked Out Before Installation! Failure To Do So May Cause Serious Injury Or Death. 1. Make field connection of heater power cord to 5 amp fuse block in fan as shown in Figure 4. 2. Make field connection of thermostat wires in heater control box. Thermostat wires are tagged HI-LIMIT INTERLOCK in heater box.
INSTALLATION Electric Heater Machine To Earth Grounding It is very important that a Machine To Earth Ground Rod be installed at the fan. The ground rod needs to be as close to the fan as possible, but no more than 8 feet away. The ground rod should be connected to the fan control panel with at least a #6 solid, bare, copper ground wire. The grounding rod located at the power pole will not provide adequate grounding for the fan.
OPERATION Electric Heater Service Start Up 1. Turn thermostat knob to its warmest position. 2. Set heater switches to ON position. Red light should be lit. 3. Watch thermometer on thermostat housing. When temperaturereaches desired level turn thermostat knob slowly to the left until heater lights go out. Remember: Electric heaters normally give no more than 5-15 degrees temperature rise. 4. Observe the heater as it runs through a few cycles to make sure thermostat is set correctly.
