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 oper-
ating pressure control will shut off the generator 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.
TORQUE VALVES
Check to insure all element flange bolts, element terminals, and con-
tactor terminals are tightened to the following specifications.
IMPORTANT:
See page 28 for
additional information
and illustrations.

WARNING SIGNAGE
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 steamroom door or adjacent to that door.
It's location must be such that all steam
bathers are readily made aware of the impor-
tant information contained in the sign.
TORQUE VALUES
Element Flange Bolts
22 lb-ft
Element Terminals
20 lb-in
Contactor Terminals

1. Exit immediately if uncomfortable, dizzy or sleepy. Staying too long in a heated
area is capable of causing overheating. Limit yourself to a maximum of ten
(10) minutes. High temperature and humidity can be dangerous to your health.
2. Children under the age of 16 should not use this facility.
3. Check with a doctor before use if pregnant, diabetic, in poor health or under
medical care.
4. Breathing heated air in conjunction with consumption of alcohol, drugs
or medication is capable of causing unconsciousness. Therefore, do not use
this facility if you have recently consumed alcohol, drugs or medications.
5. Do not contact steam head or steam at the steam head.
6. Allow yourself at least five (5) minutes after exercising to cool down before
entering this facility.
Use care when entering or exiting the steam room. Floors may be slippery and
dangerous due to moisture. Use of proper footwear is recommended at all times.
Note: For additional safety considerations see Owners manual.

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" posi-
tion. Generator switch to be in “ON" position. Since
generator will be empty, water solenoid will be ener-
gized 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 with-
in 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 cir-
cuit. The generator is now qualified for proper low
water cutout and normal liquid-level operating condi-
tions.
NOTE:
For automatic blowdown, turn timer off and on
until water level is low enough to de-energize heaters.
