Note — All Models listed with Underwriters Laboratories Inc. Table 1 — Temperature-Pressure Relationship for Steam GENERAL WARNING: Hazard of Electric Shock. Any installation involving electric generators must be effectively grounded in accordance with the National Electrical Code to eliminate shock hazard. 4. 5. Locate unit on level floor or platform. Connect water line to tagged fitting on the water control feeder. The incoming water supply must be 10 pounds greater than the operating pressure. Otherwise, a high pressure feed (pump) must be used. Wire unit following wiring diagrams supplied. (See recommendations on safety switches and fusing.) Connect steam line with an outlet valve to boiler steam outlet. Chromalox recommends using a globe valve one pipe size smaller than steam line to limit any pressure drops (surges) that may occur during start-up. Open all gauge valves and steam outlet valve. Keep drain valve closed. Turn on watter supply; water will reach operation level automatically. Close steam outlet valves. Set thermostat for desired steam pressure (see Table 1). 10. Turn boiler switch to ON position, pilot light will go on. Generator will Build up to desired pressure and shut off automatically. 11. Open steam outlet valves and use steam as needed. 12. Generator should be blown down daily (see Blowdown instructions). 13. Chromalox generators are pretested before shipment. No internal wiring or piping is required. 14. Substitution of components or modification of wiring systems without consult of manufacturer voids the warranty. 15. Power must be off when generator is drained. 16. Purchaser should use a safety switch between the main power source and the steam generator. The safety switch should use circuit breakers or fuses.

It is the best preventive maintenance you can give your generator and will add years of life to the unit. Make sure that a blowdown schedule is established and followed regularly. In extremely hard water areas, blowdown may be necessary once a day. In other areas, once each week may be sufficient. If there is a particular problem which applies to your local water condition, other than mineral content, take this into consideration in determining what schedule is to be followed. 1. At the end of the working day turn the control switch to the OFF position and close the watter supply valve. 2. If blowing down into a receptacle, allow the pressure to decrease to 15-20 psi before opening the blowdown valve. 3. It is preferable to connect the blowdown valve directly into a drainage system, if local codes permit. If this is allowed, the generator can be discharged at operating pressure. 4. When discharge is complete and the generator is drained, close the blowdown valve and open the water supply valve, allowing the generator to fill to normal level. 5. Close wall-mounted safety switch. 6. If you have been supplied with a manual reset control (as required in some states), the reset button on the control must be pushed before generator will begin developing pressure. CAUTION: Do not push reset until boiler has filled with water. 7. WARNING: The use of chemical cleaning compounds in these generators voids the warranty, unless approved by the manufacturer.
