Description of SteamPro Steam Generator
The SteamPro series generator is the latest in modern steam generator design. The SteamPro steam generator uses a printed circuit assembly to monitor and control all the equipment needed to produce steam.The system has three functions: a timer that controls the length of the steam bath; the operating water level is monitored and controlled; and the heating elements are protected by a minimum water level sensor. The generator is compartmentalized into wiring, control and tank sections. The elements can be removed through an access opening on the service side.
Maintenance of SteamPro Generators
Maintenance of the SteamPro generator includes flushing the unit periodically and visually inspecting for water leaks. Whenever the generator is opened all wiring should be inspected for any signs of overheating. All electrical connections should be checked for tightness.
Repair of SteamPro Generators
A. ELEMENT REPLACEMENT: Disconnect power from the unit. Drain the tank. Open the front and HEATING ELEMENT ACCESS covers. Note the wire connections. See diagram. Remove the element wires. Using a hot water element socket, remove the element. To install a new element, mount a new element gasket on the element. Clean the element port and add a light coat of Rectorseal No. 5 pipe thread compound to the threads. Insert and hand tighten the
B. PRINTED CIRCUIT REPLACEMENT: Disconnect power from the unit. Remove the front cover. Note where the blue wire is connected to the triple pronged water level probe. Disconnect all three wires from the water level probe. A
IMPORTANT
The blue wire connected to "L" and "P3" on the PCA must be connected to the shortest of the three level probes.
C. WATER SOLENOID REPLACEMENT: Disconnect power from the unit. Turn the water supply OFF. Disconnect the water supply from the water solenoid valve. Remove the front cover. Remove the two blue wires from the water solenoid valve. Rotate the
D. LEVEL PROBE REPLACEMENT: Disconnect power from the unit. Remove the front cover. Note where the blue wire is connected to the triple pronged water level probe. Disconnect all three (3) wires from the water level probe. Using a
IMPORTANT
The blue wire connected to “L” and “P3” on the PCA must be connected to the shortest of the three level probes.
IMPORTANT
The level probe may be extremely tight. Damage to the insulation or chassis may result unless the tank is properly blocked or supported during probe removal or installation. It may be neces- sary to completely disconnect and disassemble the generator.
