Blowdown Inspection Procedure
1. The TIMED/MANUAL switch and TIMER settings are not significant while
the ON/OFF switch is in the OFF position.
2. With the panel ON/OFF switch turned OFF, turn on electric power to the
SteamCraft 10 at the main disconnect switch. The steamer will immediately
start an automatic, 3-minute blowdown cycle. During the automatic blowdown
cycle, the condenser and drain valves are fu lly open, while the steam generator
and float assembly are flushed with fresh water.
3- Stop the blowdown cycle before it is complete by setting the ON/OFF switch to
the ON position. This energizes the operating control circuits, the red ON/OFF
indicator lights, blowdown stops, and the steam generator fills with water.
4. Restart the blowdown cycle by setting the ON/OFF switch to the OFF position.
Observe the following functions.
a.
Look at the top of the float control. There should be a steady flow of water
entering the top of the float chamber through the spray nozzle.
b. Look at the one inch vent gap between the steamer drain pipe and the floor
drain. A steady stream of water should be draining from the steamer.
c. After about 3 minutes, the cycle is complete. Check the two points listed
above; there should be no water flow at either point
Operating Test Procedures
1. Verify that electrical power to the SteamCraft 10 is turned OFF at the panel
ON/OFF switch, and turned ON at the main dis connect switch.
2. Set both upper and lower compartment TIMED/MANUAL switches to the
TIMED position.
3. Set both upper and lower compartment timers to zero minutes.
• For Key Pad Control Panels: The timer display is blank while the ON/OFF
switch is set to OFF. If the timer is not zeroed (00:00) when power is turned
on in step 4, press and hold the CLEAR key on the key pad control panel
until the timer is zeroed.
• For Dial Timer Control Panels: If the Timer is not zeroed, turn the dial
counter clockwise until it points to the 0 mark
4. Set the ON/OFF switch to the ON position. As the steam generator fills with
water, observe the following functions.
a.
The red ON/OFF switch light turns on. The fill valve opens and water
begins to fill the steam generator.
b. After a few minutes, water appears in the bottom of the float cylinders as
the water level in the steam generator rises.
• Check that no water flows from the drain opening.
• Check for plumbing leaks.
5. When the water in the steam generator reaches a safe operating level
(approximately one inch from the bottom of the float cylinder):
