Pre-Operation Check
Low water Cutoff (LWCO) and Feed Control Operation and Testing
1. All valves for incoming water supply are to be fully opened. Main disconnect switch to be in "ON" position.
Generator switch to be in "ON" position. Since generator will be empty, water solenoid will be energized allowing
the generator to fill with water until proper level is reached.Then the contactors will energize and supply voltage to
heating elements.
2.
Water level control operation:
At this point the water should be visible approximately half way up the sight
glass. Slowly open the drain valve located at bottom of the generator.The water level will fall allowing the low water
cutoff/water level control to energize the feed water system. Close the drain valve for proper operation.
3.
Low water cut-out switch performance
. Close water feed valve. Open the drain valve completely. Maintain this
condition until the water level falls within the gauge glass enough to cause the low water cutout switch to de-energize
the heating elements. All contactors will be in the de-energized state at this time. Close the drain valve. For automatic
re-setting type low water cutoff switches, feed system will return the water level to normal. For manual re-set the reset
button must be depressed to complete circuit.The generator is now qualified for proper low water cutout and normal
liquid-level operating conditions.
NOTE:
For automatic blowdown, turn timer off and on until water level is low enough to de-energize heaters.
Pressure Controls Operation and Testing
Steambath generators are provided with one hi-limit pressure control and at least one operating pressure control.
1.
All pressure controls are equipped with a screw allowing for setting of the desired operational and hi-limit
pressures.
2.
It is recommended that the hi-limit control be set at 8–10 psig maximum and the operating pressure control(s) shall
not be set above 5 psig.
Note:
Models CU360 - CU3000 are provided with one (1) automatic reset operating pressure control and one (1)
manual reset high limit pressure control. Models CU 4500 is provided with two (2) automatic reset operating
pressure controls and one (1) manual reset high limit pressure control.
3.
Pressure control operation check:
Manually close the steam outlet valve. Switch the generator on to allow for
steam pressure build-up. Pressure gauge reading will build and the operating pressure control will shut off the gener-
ator at the pressure setting . Re-setting the operating pressure control is accomplished by manually bleeding off
pressure through the steam outlet valve and allowing the pressure to drop below the desired set point.
Warning Sign
The CU Steambath generator is provided
with a WARNING sign.This WARNING is
to be secured to the outside of the steam
room, on the steam room door or
adjacent to that door. It's location must be
such that all steam bathers are readily
made aware of the important information
contained in the sign.
Attention Guests:
1.
Children under the age of 16 should not use the
Steamroom.
2.
People who are pregnant, have heart disease, have a
coronary condition, have elevated blood pressure, are
in poor health, are being treated for any other medical
condition, or are using medication or drugs should not
use the steambath unless authorized by their physician.
3.
Exit Steamroom immediately if you feel faint, dizzy,
sleepy, or otherwise uncomfortable.
4.
Do not use the Steamroom if you have recently con-
sumed alcohol.
5.
Condensation and moisture may cause the Steamroom
floor and other surfaces to become slippery and dan-
gerous. Use of proper footwear is recommended at all
times.
