Important Steam Bath Safety Guidelines
- 3 -
Models: HC-9 thru HC-24 with DCCP Control
I. Important Steam Bath Safety Guidelines:
A) Do not permit children to use the steam bath unless they
are closely supervised at all times.
B) Wet surfaces of the steam enclosures may be slippery.
The floor should be skid resistant. Bathers should use
care when entering and leaving.
C) The steam head is hot. Bathers should not touch the
steam head and avoid contact with steam near the steam
head.
D) Prolonged use of the steam bath can excessively raise
the internal human body temperature and impair the
body’s ability to regulate its internal temperature
(hyperthermia). Limit the use of steam to 10 – 15 minutes
until you are certain of your body’s reaction.
E) Excessive temperatures have a high potential for causing
fetal damage during the early months of pregnancy.
Pregnant or possibly pregnant women should consult a
physician regarding correct exposure. Obese persons and
persons with a history of heart disease, low or high blood
pressure, circulatory system problems, or diabetes should
consult a physician before using the steam bath.
F) Persons using medication should consult a physician
before using a steam bath since some medication may
induce drowsiness while other medications may affect
heart rate, blood pressure and circulation.
G) The Facility manager should fully understand the causes,
symptoms, and effects of hyperthermia which may be
described as follows: Hyperthermia occurs when the
internal temperature of the body reaches a level several
degrees above the normal body temperature of 98.6° F.
The symptoms of hyperthermia include an increase in the
internal temperature of the body, dizziness, lethargy,
drowsiness, and fainting. The effects of hyperthermia
include:
1) Failure to perceive heat.
2) Failure to recognize the need to exit the steam bath.
3) Physical inability to exit the steam bath.
4) Unawareness of impending risk.
5) Fetal damage in pregnant women.
6) Unconsciousness.
WARNING: The use of alcohol, drugs, or medication
can greatly increase the risk of hyperthermia.
II. Warning Sign Installation:
The warning sign shown below and provided with the genera-
tor MUST be permanently installed on the steam room door or
the wall immediately adjacent to the steam room.

Pre-Installation Models: HC-9 thru HC-24 with DCCP Control
The Heavy Commercial steam generator (HC-9 thru HC-24)
comes from the factory assembled, carefully wired, and tested.
Please read all instructions before installing or servicing.
IMPORTANT:
1. All Plumbing and Electrical work must conform to
local and national codes.
2. All power must be OFF to the steam generator when
installing or servicing the unit.
3. Do not use or install unauthorized components,
accessories or products on the generator or its'
piping.
III. Pre-Installation:
The following general information should be used in conjunc-
tion with your architect, designer and contractor in providing a
suitable and safe steam room environment for the steam
bathers.
IMPORTANT: Refer to the specification plate affixed to
the cabinet of the steam bath generator.
A) Insure that the model steam generator unit purchased is
sized adequately for your steam room.
B) Be sure to have the proper electrical supply. Determine
proper size of wire, voltage, amperage, and phase for the
steam generator based on the specification plate attached
to the generator and the chart in the back of this manual.
C) Provide an inline fuse/circuit breaker as required sized in
accordance with specification chart. Do not install a GFI
Ground Fault Interrupter to this equipment.
D) Select a location to install the generator to allow sufficient
room (See Access Area Requirements) for access to the
unit in the event service is required. Select a clean dry
indoor location protected from freezing. Do not store
flammable materials such as gasoline, thinners, paints,
etc. in the same area as the steam generator. Do not
store corrosive materials such as chlorine near the steam
generator.
E) Location of the steam generator should be placed where
the ambient temperature range is: 40ºF to 104ºF.
E) For safe low temperature draining (blow down) of the
steam generator it may be necessary to drain into an
ASME blow down tank. If required additional space for the
tank will be necessary. Consult with your architect or
licensed plumber. The blow down process can potentially
dump boiling water down the drain and damage the
drainage system.
F) The steam generator should be located as close as
possible to the steam room. If the steam generator is
more than ten feet from the steam head, insulate the
steam pipe with appropriate pipe insulation rated for a
minimum of 250ºF.
G) The serial number plate should be visible when installed.
H) The steam room must be completely sealed on all sides,
top and bottom. Floor, walls, and ceiling should be
completely covered with waterproof material such as tile.
Floor and bench materials must be slip resistant (see
Safety Guidelines).
I) Provide a floor drain inside the steam room for condensate
run-off and steam room cleaning.
J) Only water tight lighting fixtures approved for the applica-
tion should be used.

Rough-In
IV. Rough-In:
A) Plumbing Rough-In:
The heavy Commercial “HC” Steam Generator requires
the following connections: 1/2" NPT piping for the water
inlet, 3/4" copper tubing for each steam outlet, and 3/4"
NPT safety valve should be piped to an indirect waste
line. A 1” drain line for an optional auto blow down
assembly must be piped to an indirect waste.
IMPORTANT: The Optional Auto Blow Down feature
can dump a few gallons of boiling water down the drain
and potentially damage the plumbing. It may be
necessary to drain into an ASME Blowdown Tank
(Available as an option from Steamist) depending on
the requirements of plumbing system and local codes.
1) Rough-in a ½" water line from a cold water supply.
Provide a local shut-off valve.
2) Rough-in the steam line using 3/4" copper tubing. Do
NOT use iron or galvanized pipe, it will rust and
discolor wall of steam room. For a steam line that is
longer than 10 feet use an appropriate pipe insula-
tion rated for a minimum of 250ºF. The steam head
should be located approximately 18" above the floor
and as far from the bather as possible. Do NOT
install shut-off valves in this line. Do NOT create
traps or valleys in this line which would trap conden-
sation and block the flow of steam.
3) Rough-in a 1” drain line for a manual drain or an
optional auto blow down assembly and provide for
an indirect waste, to be used for draining steam
generator.The indirect drain must be in accordance
with local plumbing codes.
4) Rough-in a drain line using ¾" pipe routed to an
indirect waste from the Safety Relief valve. The
discharge end of this pipe must NOT be restricted in
any way. It must be piped in a way that would safely
discharge steam and/or boiling water in the event of
a failure. Always follow local plumbing codes.
B) Electrical Rough-in:
1) Route power supply cable to the location where the
steam generator will be installed.
2) Route control cables as described in the Digital
Command Center.

Rough-In / Installation Models: HC-9 thru HC-24 with DCCP Control
C) Digital Commercial Control Package rough- in:
The DCCP is factory wired for either one or two steam
rooms. The following installation instructions are typical
for both room installations. IMPORTANT: The command
center cable, USER BYPASS CONTROL cable and
sensor cable are not the same and must not be confused.
1) Digital Command Center rough-in: Route the command
center cable from the generator to the selected dry mounting
location convenient to the facility operator.
IMPORTANT: the cable is 50’ long. 100’ cable is
available by special order. Maximum functional cable
length is 100 feet.
2) USER BYPASS CONTROL: Route the USER
BYPASS CONTROL cable from the generator to the
selected area outside of the steam room.
3) Room Temperature Sensor: Route the temperature
sensor cable from the generator to the selected
location inside the steam room. For sensor installa-
tion and location, see Figure 3. Make sure the
generator end is located near the generator mount-
ing location and the sensor end is located near the
sensor mounting location. Important: the cable is 50’
long. 100’ cables are available by special order.
Maximum functional cable length is 100 feet.
V. INSTALLATION
A) Plumbing Installation: Care must be taken when installing
the steam generator. Leave proper access for servicing
(See Installation Area Requirements). (Refer to Figure 3
for typical steam generator installation.) CAUTION: The
steam generator is designed to be used ONLY in an
upright and level position; to do otherwise would damage
the unit and void the warranty. For convenient access
mount the steam generator on the optional Steamist
stand designed specifically for the steam generator.
1) Water supply: Purge the water supply line before
connecting to the steam generator. In areas where
high water pressure may be a problem a water
hammer arrestor should be installed.
2) Steam line: Connect the steam line from the previ-
ously roughed-in location to the steam solenoid
valve on the generator marked “steam outlet.” If the
generator is equipped to provide steam to two rooms
care must be taken to make sure the proper steam
solenoid is piped to the proper room.
3) Safety Line: Connect the 3/4" NPT safety valve into
the previously installed indirect waste line.
4) Optional automatic blow down: Pipe into the 1"
indirect waste line.
5) For steam head installation (see Page 15).
6) The steam, safety, and drain pipes become hot
during operation and should be insulated with
appropriate rated pipe insulation to protect against
accidental contact.
B) Electrical Installation: WARNING ALL POWER TO THE
STEAM GENERATOR MUST BE TURNED OFF.
1) Remove the top access cover to the electrical power
compartment . (See Figure 4.)
2) Locate appropriate knockout and mount a proper
strain relief into knockout hole.
3) Strip back the power cable’s outer insulation jacket
and insert into the box. Strip back insulation 3/4"
from the incoming wires: single phase (two power
and one ground). 3 phase (three power and one
ground).
4) Insert ground wire into grounding lug.
CAUTION: Make sure ground wire does not come in
contact with live electrical connections.
5) Locate power block and insert power wires into
proper power lug terminals on top of the block and
secure.
C) Aroma Pump Option: The aroma pump requires a
separate 15 amp 120 volt branch circuit to be connected
(see Figure 4). This is only necessary to run the aroma
pump and is not needed if the pump is not used. To
connect the power, remove the top cover of the generator.
Select the knock out to route the 15 amp 120 volt line into
the box. Connect the neutral, hot, and ground to the
terminal block. Replace the cover. Plug in the pump into
the appropriate receptacle depending on which room the
pump is connected to.
NOTE: The pump will only pump when the appropriate
room control is in the MAX mode, the ambient room
temperature of that room is above the IDLE setting and
the steam valve for that room is on. This feature
reduces oil consumption by limiting the pumping to the
max mode only. Maximum economy of oil consumption
can be realized by programming the DCCP to remain in
idle mode throughout the day. If programmed this way
the oil will only be dispensed when a steam bather
presses the button on the user control outside the
steam room switching the steam bath to MAX mode for
a preset time defined by the manager (recommended
setting is 10 minutes). Programmed this way the oil is
only pumped on the demand from the user and is a
substantial cost savings (See Operating Instructions
page 9).

Owners Manual
Digital Command Center Installation Models: HC-9 thru HC-24 with DCCP Control
VI. Digital Command Center Installation:
WARNING: All the electrical power to the steam
generator MUST be turned OFF before proceeding with
installation.
A) The DCCP comes factory wired for either one or two
steam rooms. The following installation instructions are
typical for both room installations. The configuration for
one or two room is set at the factory. When the generator
is configured for two rooms (SRP-Second Room Package
must be ordered) it will have 2 room temperature sensors
(one per room), two electric steam valves, two USER
BYPASS CONTROLs, and two steam heads. The electric
steam valves will be labeled 1 and 2. The connections for
the sensors, USER BYPASS CONTROL(s), and aroma
pumps, will all be labeled for room 1 and room 2. It is very
important to pay attention not get the connection to room
1 and room 2 crossed. If the generator is configured for
one room there will not be any special markings.
B) USER BYPASS CONTROL(s): The USER BYPASS
CONTROL should be located outside the steam room
door convenient to the bather. This control gives the
bather limited control of the steam room. The system will
operate without this control but this function is lost. See
the operating instructions for further information on this
function. Route the USER BYPASS CONTROL wire from
the selected mounting area to the control board in the
steam generator (see Figue 6 and 7). The USER
BYPASS CONTROL mounts to 2-1/8” or 55 mm round
hole in the wall.
C) DIGITAL COMMAND CENTER is intended to be used
solely by the manager. It should be located at a conve-
nient height for programming. It may be mounted on the
wall of the utility room near the steam generator, in the
manager’s office, or the front desk. The factory supplied
wire is 50 feet long, therefore the generator must be
located within its reach.
IMPORTANT: The digital command center is unique
and not to be confused with the USER BYPASS
CONTROL wires or the sensor wires. The Digital
Command Center uses a 4 wire connector, the USER
BYPASS CONTROL uses a 6 wire connector and the
room sensor uses a 2 wire connector. Route the Digital
Commander Center wire from the selected mounting
location to the control board located in the steam
generator (see Figure 6 and 7). The Digital Command
Center mounts to a hole in the wall 2-1/2”w x 7-7/8”h.
D) Room Temperature Sensor(s): The room temperature
sensor is required for operation. The sensor must be
located in the steam room approximately six feet above
the floor and never closer than one foot to the ceiling or
the corner of the room. Route the cable from this location
to the control module on the steam generator. The sensor
mounts to a 5/8” hole in the wall (see Figure 5 for more
detail).

Digital Commercial Control Package Operation Models: HC-9 thru HC-24 with DCCP Control
VII. Digital Commercial Control Package Operation:
This control is designed to maximize energy savings by
allowing the facility manager set a lower operation temperature
called IDLE TEMP and also satisfy the steam bather with the
ability to by-pass this feature on demand by pressing the
USER BYPASS CONTROL button. Unlike a typical 24 /7 timer
which has only an ON or OFF mode, the Digital Command
Center has three modes MAX, IDLE and OFF. MAX is the
normal ON mode reserved for peak hours of use when the
steam room is held at the optimum steam bath temperature.
IDLE mode is the energy saving mode. IDLE is set below the
MAX temperature and provides a significant energy savings.
As needed, the steam bather can easily switch to the MAX
setting by pressing the button on the USER BYPASS CON-
TROL.
A) USER BYPASS CONTROL: The USER BYPASS CON-
TROL button is only functional during the IDLE mode. In
the IDLE mode the USER BYPASS CONTROL, typically
mounted at the entrance to the steam room, is waiting for
the user to press the button and select the MAX mode.
IDLE mode is indicated on the USER BYPASS CON-
TROL by one lit bar. Pressing the USER BYPASS
CONTROL button starts the MAX CYCLE TIMER and
immediately begins to heat the room to the MAX setting.
This temporary MAX CYCLE TIMER is programmable up
to 60 minutes by the facility manager. MAX TEMP mode
is indicated by all bars lit. When the Digital Command
Center is set to MAX TEMP the USER BYPASS CON-
TROL icon displays max (all bars lit). In the MAX TEMP
mode the USER BYPASS CONTROL buttons do not
function. When the DIGITAL COMMAND CENTER is in
the OFF mode the USER BYPASS CONTROL icon will be
off (no bars lit) and the user buttons do not function.
B) Programming the DIGITAL COMMAND CENTER can be
broken down into 3 separate sections, SET EVENT, SET
VALUE, and SET CLOCK. The buttons on the control are
grouped accordingly. SET EVENT is used to set the time
and day that a particular mode (MAX, IDLE, or OFF) is to
begin. SET VALUE is intended to set the MAX and IDLE
temperature as well as the MAX CYCLE TIMER. The SET
CLOCK section is only for adjustment of the current time
and day. The DIGITAL COMMAND CENTER display light
comes on when any button is pressed. The light will
remain on for 5 minutes after the last button is pressed.
1) SET CLOCK: The SET CLOCK section of the Digital
Command Center is used exclusively for setting the
current time and day. It is a convenient place to
make changes for daylight savings time without
having to reprogram other settings. The clock has a
battery backup in the Control Module that will keep
time for up to one year with no power.
(a) DAY Setting: Press the lower DAY button to
toggle the current day of the week.
(b) HOUR Setting: Press the lower HOUR button to
select the current AM or PM hour and the
correct hour will be displayed.
(c) MINUTE setting: Press the Lower MINUTE
button until the correct minute is displayed.
2) SET VALUE: The SET VALUE section of the keypad
is used to program the following 4 parameters:
(a) MAX1 TEMP is used to set the maximum
desired operating temperature of the steam
bath. It is set by pressing the button until the
preferred maximum temperature is displayed.
Note: The MAX TEMP cannot be set lower than
the IDLE TEMP. Selection of the MAX TEMP
setting is at the discretion of the facility
manager.
(b) MAX2 TEMP (only available with SRP) is used
to set the desired operating temperature of a
second steam room. It is programmed the same
as MAX1 TEMP.
(c) IDLE TEMP is used to program a lower
temperature setting during periods of less
frequent usage. It is set by pressing the button
until the desired set-back temperature is
displayed. The feature can be disabled by
setting it to 00.The IDLE TEMP cannot be set
higher than the lowest MAX TEMP value.

(d) MAX CYCLE TIMER is used to set the duration
that the system will be in MAX TEMP mode
after the USER BYPASS CONTROL button is
pressed in. It is set by pressing the correspond-
ing button on the Digital Command Center.
Each time the button is pressed the minutes will
increase in one minute increments from “:00” to
“:60”. If the MAX CYCLE TIMER is programmed
to “:00”, this feature will be disabled and the
USER BYPASS CONTROL(S) will be disabled.
(e) Degree °C or °F change is made by placing a
jumper over the CN112 pins for °C or by
removing it for °F (Jumper not included). The
power must be OFF when making this change.
See Command Module on Wiring Diagram
page 14.
3) SET EVENT: Before programming the SET
EVENT, it is necessary to determine the hours
the steam bath will operate and in which mode.
Each day of the week can have up to six events
programmed. The chart on the following page
will help organize your plan for the SET EVENT
function. The top 2 sections of the chart are
filled in with 2 examples
NOTE: Program #1 is set to 12:00am by default.
This time cannot be altered. You can however set
12:00am to: OFF, IDLE, or MAX.

EXAMPLE 1 shows the club opening at 8AM. Assuming it is
not busy the first few hours so the mode is selected as IDLE.
Then at 10AM it gets busy and the program switches to MAX.
At 3PM it slows down again and the control switches back to
IDLE. Then at 7PM it gets busy again and switches to back to
MAX. At 10PM the club closes.
EXAMPLE 2 shows the club opening a 8AM and set to IDLE
all day until 10PM when the club closes. This would yield
maximum energy savings and is the recommended program.
At any time the system is in IDLE mode the user can activate
the MAX TEMP mode by pressing the USER BYPASS
CONTROL button.

4) Programming SET EVENT: To program the SET
EVENT section, first press the PROG# button on the
Digital Command Center. The display will flash the
current program number and show the start time of
that program. The program can only be changed
while flashing. To enter a new program, first press
the DAY button in the upper SET EVENT section to
choose the individual day or a block of days (i.e.
M-TU-W-TH-F, or SU-M-TU-W-TH-F-SA). With the
proper day(s) selected, press the MAX/IDLE/OFF
button to choose the mode for program 1.
Note: The time for program 1 is factory fixed to
12:00am, if the steam bath is to start at a later time,
Program 1 must be set to Off.
Program 1 is complete. Press PROG# button to get
to program 2. Enter the start time of program 2 and
select the mode. You are only programming the start
time of each program. The end time is automatically
the start time of the next program. The last program
entered is limited to 11:59PM. If the facility operates
beyond midnight, program 1 of the next day must be
set to 12:00 AM for continuous operation. Follow the
same process for all the programs and days of the
week. To exit the programming mode, press the
ENTER button or wait 30 seconds and it will stop
blinking and your changes will be saved.
Note: Programs 1 through 6 are sequential and
therefore it will not be possible to set a new program
before the end of the previous program.
(a) Programming Tip: To modify an existing
program press the PROG# button and the
upper DAY button to get to highlight the
program you want to change. Then modify the
setting with the appropriate button. Entries will
be saved automatically in 30 seconds or by
pressing the enter button.
(b) Programming Tip: If the facility operates on
nearly the same schedule every day, it may be
easier to program all seven days to the same
common program and then go back and
program Sunday to be off if the facility is closed
that day.
(c) Programming Tip: You can review your program
by pressing the PROG# button and toggling
through the programs and toggling through the
days of the weeks, and observing the time
settings. If you made no changes simply press
the enter button to return to normal or it will
return in 30 seconds.
(d) Programming Tip: When reviewing the program
and a block of days are selected, if all the
individual programs for those days do not
match, the clock will display --:--. This is normal
and any adjustments made at this time will
reprogram all days selected to match the new
entry.
5) Manager lock function: The Digital Command Center
has a locking feature that prevents any setting to be
changed when locked. To lock the control, press the
lock button, the lock icon will flash for up to 30
seconds. While the icon is flashing, press any three
consecutive buttons, and then press the lock button
again to confirm. The three consecutive buttons
pressed are the password. The system control will
be locked and the lock icon will be on steady. To
unlock, press the lock button and then press the
same three consecutive buttons as the previous
password, the system will be unlocked and the lock
icon will disappear. If the password is lost or forgot-
ten, it can be reset. This will require two people. Turn
off the main power (circuit breaker), have a second
person then press and hold the lock button on the
Digital Command Center while the first person turns
the power back on. The system will be unlocked.
Also see the reset section for an alternate method
(step 11).
6) Temporary Mode setting: By pressing
IDLE/MAX/OFF button on the Digital Command
Center you can temporarily change the current mode
(IDLE/MAX/OFF). This is only a temporary change
until the next programmed event.
7) Auto-Blow Down: The optional auto-blow down
becomes active in the OFF mode. When first
entering OFF mode, the steam valves will deactivate
and the generator will continue to maintain normal
pressure. After 5 minutes the generator will shut
down and the drain will open. Boiling water will exit
under pressure and the water valve will turn on to
help flush the generator. After 2 minutes the drain
will close and the generator will refill. After a total of
7 minutes the generator is ready to start a new cycle.
If the facility is operated 24 hours a day, a 7 minute
OFF mode should be programmed in to allow for a
proper drain cycle. In areas where the water is hard,
a second drain cycle can be programmed by adding
an extra 7 minute off mode program.

Digital Commercial Control Package Operation Models: HC-9 thru HC-24 with DCCP Control
minute OFF mode during an “Off-Peak” daytime
period. IMPORTANT: Due to possible code violations
or damage to the building drainage system the hot
boiling water exiting in this process may require a
Blow-Down Tank. Consult with your licensed
contractor. Blow-Down tanks may be purchased
separately.
8) Steam Control: The steam valve(s) are controlled
according to the room temperature sensor(s) and the
programmed mode. When the room temperature is
lower than the set temperature by one degree the
steam valve will turn on. When it reaches the set
temperature it turns off. If for some reason the room
temperature exceeds the MAX TEMP setting (of
either room) by more than 10 degrees the Digital
Command Center will turn off the generator until that
room temperature drops to 1 degree below the set
temperature.
9) Aroma Control: There are two aroma control relays
(one for each room) located in the Command Module
on the generator. These relays can be used with
most aroma pumps available. The relays are
programmed to conserve aroma therapy oil. The
relays are only on when the following conditions are
met. The program for that room must be in the MAX
mode, the steam valve for that room must be on and
the temperature in that room must be above the IDLE
setting. When all these conditions are met, then the
aroma relays will energize.
10) Fahrenheit and Celsius: The Fahrenheit or Celsius
temperature can be selected by changing a jumper in
the Command Module (CN112). When it is not
connected (open circuit), it will be Fahrenheit. When it
is connected, it will be Celsius. The Jumper must be
switched with power off (See wiring diagram on page
11).
11) Reset Feature: If it is ever necessary to reset all the
programs and start over press and hold the PROG#
button and the lower MIN button for five seconds
simultaneously. This will reset every setting in the
Command Center. This process can also be used to
unlock the control if the password is lost or forgotten.

7. Center and square the back plate over the nipple. While
holding it in place screw the head on to the nipple hand
tight.
8. Adjust the back plate and head to line up squarely.
Remove any excess silicone with rubbing alcohol.
NOTE: The steam head has been designed with a 360
degree dispersion of steam to improve circulation and
to minimize the hotspots created with the traditional
steam heads. For maximum comfort the steam head
should always be located as far from the seating area
as possible. Should the location of the steam head
necessitate blocking the steam from a particular
direction to improve bather comfort, the supplied
deflector plate can be added to any of the three sides
shown to help divert the steam away from the bather.
The deflector is attached to the back side of the head
before installation with 2 stainless steel screws
provided.
1. Make sure the 3/4” nipple protrudes beyond the tile ¼" to
½".
IMPORTANT: If the nipple protrudes beyond ½” the O-ring will
not make a proper seal and the nipple will have be adjusted.
2. Wrap the threads of the nipple with pipe sealant tape.
3. Make sure the head will line up in the upright position when
tightened. The head should only be firmly hand tight. Using a
wrench on the head may damage it. Screw the head on to the
nipple and see how it lines up. Once a proper alignment is
made remove the head.
NOTE: If necessary the head can be repositioned by disas-
sembling the hub from the cover and selecting one of the two
alternate positions as shown in figure 1.
4. Re-apply sealant tape if necessary.
5. Place a bead of silicone around the pipe, sealing the pipe to
the wall.
6. Place a bead of silicone around the back outer edge of the
back plate.
