1.  STEAM GENERATOR LOCATION 
 

The RELAX-A-MIST steam generator and its 
controls must be located in a dry environment 
preferably 3 feet above the floor.  The steam 
generator is approximately a 3 foot cube and 
there should be a minimum clearance of 30 
inches on each side, the back, the top and at 
the front. There should be no more than 25 
feet of steam pipe per steam line between the 
generator and the steam nozzles.  The steam 
generator must be accessible for service and 
maintenance.   There must be a drain close by 
into which the steam generator can be drained 
on a daily basis.  Preferably, the steam 
generator and its thermostat controls will be in 
a mechanical room adjacent to the steam 
room.  Install the steam unit on the Relax-A-
Mist metal stand (purchased separately) Ask 
dealer for details.  The steam unit must be 
level.  There are four 1/2" bolts holding the 
shipping boards to the bottom of the steam 
generator.  The bolts are to be used for 
leveling purposes once the shipping boards 
have been removed. 

 

Note: Do not install the steam generator on the 
  

shipping 

boards.

GENERAL

   The commercial Relax-A-Mist 

steam generator is designed specifically to 
heat and steam areas for steam bath 
purposes.  The controls are all supplied (built- 
in where feasible), including a digital 7 day, 24 
hour time clock to start the steam operation in 
the morning and stop it at night. An automation 
option is built-in to allow the operation of 
remote switching to replace the time clock 
operation. The generator is designed to 
operate continuously, or intermittently, as heat 
and steam are required by the steam room 
thermostats.  The steam room thermostats 
single temperature sensor is connected by a 
factory supplied 25 foot wire. 

 

 

 

  These thermostats control 2 steam room 

temperatures. One thermostat is LOW or 
standby temperature and the other is for HIGH 
or operating temperature.  The low 
temperature cycle is activated by the time 
clock switching the steam unit on for its daily 
operation.  The high temperature cycle is 
activated by an air switch button mounted on 
the factory supplied plate light assembly. 
Locate this button plate assembly inside or 
outside the steam room and close to the door.  
When a person wishes to steam bath, they 
push the button activating the steam cycle for 
30 minutes and the light illuminating indicates 
the cycle has started.  The button also turns 
the cycle and light off should a person end 
their steam bathing before the 30 minute cycle 
is completed. 
 
There is a built-in drain/flush system that 
operates when either the time clock or the 
remote switch turns the steam operation off.  
At the start of the drain/flush operation, the 
flush valve introduces a burst of water to the 
interior of the steam generator to cool the 
boiling water.  Then the automatic motorized 
drain valve opens followed by six separate 14 
second flushes over a 20 minute period. 
 
This is necessary as the only substance that 
leaves the generator during a steam operation 
is pure steam and all of the dissolved solids 
carried in with the water remain in the steam 
generator.  During a 10 hour operational day, 
the dissolved solids from approximately 30 to 
90 gallons of water (depending on the boiling 
tank size) are left in the approximate 2-1/2 
gallons of water in the steam generator.  If this 
residue is not drained on a daily basis, the 
resulting mineral buildup may hamper the 
steam unit operation and void the warranty. 
Note:  See "WATER SUPPLY" on page 2 and 
“CAUTION 6" on page 5.
