1. GENERAL INFORMATION (See “SELECTION” p.5).
STEAM GENERATOR LOCATION The steam
generator should be located in a ventilated area outside
of, but within 20 feet of the shower or steam room,
where the steam pipes can be installed without the
possibility of a steam trap. The steam generator may
be placed under the floor, in a closet or any convenient
location where it WILL BE LEVEL, DRY, AND WILL
NOT FREEZE in the winter. The steam generator
MUST be easily accessible should service be required
in the future. INSTALL THE STEAM GENERATOR
WITH THE COPPER STEAM PIPES COMING OUT
OF THE TOP OF THE APPLIANCE AND THE
ELECTRICAL BOX FACING THE ACCESS! See Fig1.
STEAM PIPES AND STEAM NOZZLE (To and in the
Steam Room) The steam pipes must be a minimum of
½ inch I.D. rigid copper pipe between the steam
generator and the area to be steamed. Installing the
steam pipes using the most direct or shortest route
(WITHOUT FORMING A STEAM TRAP) and with the
fewest number of elbows will, in most cases, maintain
a lower pressure (less than 1 lb) in the boiling tank than
a longer route with many elbows.
CAUTION: There is to be NO RESTRICTION in the STEAM PIPES
BETWEEN the STEAM GENERATOR and the STEAM NOZZLES that
would in any way cause PRESSURE to build in the STEAM
GENERATOR. INSTALL the STEAM NOZZLE 12" above the finished
flooring, in a LOCATION where the STEAM WILL NOT BURN anyone.
During the final installation, the steam nozzles supplied
MUST be used. See “Steam Piping to Bath or Shower”.
“CAUTIONS 1 and 3" and Fig. 2.
TIMER SWITCH (Steam Generator Control.)
The Quick Touch Timer can be located inside or outside the
steam room. If using the optional Time and Temperature
Control, refer to that control's installation instructions now.
Relax-A-Mist Timer Switches are not a precision timing
device. See “CAUTION 11”
DRAIN VALVE OPTION (Ask Dealer For Details)
A 3/4 inch copper, female adapter (located below the water
supply connection), can be plumbed to a drain with either a
manual shut off or an automatic drain valve installed at the
steam generator (purchased separately) See Figure 2.
2. ROUGH-IN
WATER SUPPLY (According to Local Plumbing Code) The
water supply pipe should be equipped with a shut off that is
accessible and close to the steam generator. Installation of
a water hammer arrester (water bumper) is recommended.
To maintain a proper water level in the generator the water
supply should have a minimum of 20 lbs pressure. If the
water supply contains impurities that could cause scale
build-up or corrode the steam generator, install appropriate
water treatment. See “CAUTION 4" and “WARRANTY
POLICY”. See diagrams on Page 6.

2
DRAIN VALVE OPTION (According to Local
Plumbing Code.) 3/4 inch rigid copper piping must be
installed from the steam generator location to a drain.
Ensure that all water is able to drain from all sections
of the drain line at all times. Ask dealer for automatic
drain details.
ELECTRICAL - WATTS, WIRE AND FUSE SIZES
According to local electrical code. Use copper wire only.
Must be installed by qualified Electrician.

Fuse/Breaker Size 40 Amp 50 Amp
Copper Wire - Supply #8 AWG #6 AWG
Copper Wire - Switch #22 AWG #22 AWG
Check to ensure that the supply voltage (either 208V or
240V) is compatible with the voltage listed on the
steam generator identification label (below water
supply). The fuses or circuit breaker must be of
adequate size to carry the necessary amperage to
operate the steam generator.
Select a convenient location in the steam room, within
20 feet of the steam generator, (5 feet up from the
finished floor, away from the area above the steam
nozzles) to install the Quick Touch Timer (found in the
appliance electrical box) and cord set packaged with
steam unit. Cut a 7/8 inch hole in the wall material and
pass the female end of the cord set through the wall for
final installation. OR, the Time and Temperature
Control with remote may be installed (purchased
separately). ASK DEALER FOR DETAILS.
There is one copper “2 wire and ground power cable”,
class 1 wire, and one factory supplied “25 foot control
wire”, class 2 wire, to be run to the steam generator:
a - Run a copper power supply cable, 2 wire and
ground of adequate gauge to carry the
necessary amperage from the fuse or circuit
breaker to the steam generator location.
b - Run the factory supplied “25 ft cord set” from the
steam generator location to the Timer Control
location. Leave sufficient length at each end of
cord set for the final installation connections.
SEE “CAUTION 8, 9 and 10".
THE ELECTRICAL ”SUPPLY” FOR THE STEAM
GENERATOR CAN NOT BE SWITCHED DIRECTLY
BY THE TIMER CONTROL SUPPLIED WITH THE
STEAM GENERATOR. Use Copper Supply Wire Only .
The copper power supply cable must run directly, from
the fuse or circuit breaker to the steam generator. The
factory supplied cord set must be run directly from the
steam generator to the Timer Control. The Timer
Control activates a contactor in the steam generator,
through the class 2 voltage circuitry.
STEAM PIPING TO BATH OR SHOWER (½ inch rigid
copper pipe required) Install two ½ inch rigid copper pipes
(maximum 20 feet each) from the steam generator to where
they will enter the steam bath area, in a location where the
steam will not burn anyone. Insulate the steam pipes for
maximum efficiency. WARNING STEAM NOZZLE IS HOT
The end of the steam pipes in the steam room should each
have a ½ inch female pipe thread fitting that is attached to
something solid, (example: a “wingback 90 elbow” used to
rough in a shower head). For steam nozzle location
purposes during rough-in, install ½ inch iron pipe nipples
into the two female fittings (hand tight) so they will protrude
through the wall into the steam room. After the finished
walls are in place, the iron nipples are to be replaced by
brass nipples the appropriate length. See “FINAL
INSTALLATION STEAM PIPING” and Fig, 3.
1 - Steam Nozzle
2 - Escutcheon
3 - Finished Wall
4 - Sealer (silicone)
5 - ½” Brass Nipple
6 - ½” C x FIP. Adapter
7 - ½” Rigid Copper Pipe
8 - ½” CxC Wing Elbow
9 - 12" from steam pipe
to steam room floor.
Warning: Steam Nozzle is HOT
In a shower or steam room the centre of the brass nipples
and steam nozzles must be 12 inches above the finished
floor, and in a location away from the users pathways,
where the steam will not burn anyone, preferably on the
same wall as the shower head. See “Figure 4".
If the steam nozzles are installed too low, the steam will
strike the floor (may cause damage to tile grout) and
condense into water before it can heat and steam the room.
Installing the steam nozzles correctly, in the lower part of
the room ensures a more even distribution of the heat and
steam.
It is not recommended
to place the steam
nozzles under a bench,
as there is a distinct
possibility that someone
sitting on the bench
could inadvertently put
their feet underneath it
and be burned. When
the steam nozzles are
under a bench it is
sometimes impossible
for the heat and steam
condensate to circulate
throughout the room.

Care MUST be taken to AVOID A STEAM TRAP!
Water must be able to drain from all sections of the
steam pipes at all times. See “CAUTIONS 1 AND 2"
and Fig. 5.
3. FINAL INSTALLATION
WATER SUPPLY (According to Local Plumbing Code)
The water inlet connection on the steam generator
is a male garden thread. A swivel garden hose to
3/8 inch tubing adaptor is supplied for the installer’s
connection. The swivel adaptor will be a union.
Install a shut off on the water supply and reduce it to
use 3/8 inch O.D. soft copper tubing. Use 3/8 inch
O.D. soft copper tubing between the shut-off and
the swivel adaptor at the steam generator. Form a
“loop” in the 3/8 inch soft copper tubing to ensure
the boiler is being installed level. See Fig. 6.
DRAIN VALVE OPTION (According to Local Plumbing
Code.) Install the shut off (purchased separately)
within 1 foot of the steam unit, between the 3/4 inch
copper female adapter and a 3/4 inch union
attached to the drain line. For the automatic drain
option, ask your Dealer for details.
ELECTRICAL (According to Local Electrical Code.)
Check to ensure that the supply voltage (either
208V or 240V) is compatible with the voltage listed
on the steam generator identification label (below
the water supply). Pull the roughed-in copper
supply cable (2 wires and ground) into the steam
generator electrical connection box using the knock
outs and proceed with “a & b” as follows; move the
control cord set to the outside right of the electrical
connection box and proceed with “c & d” as follows:
a - Connect the copper power supplyground wire
to the Relax-A-Mist grounding lug inside the
appliance’s electrical connection box.
b - Connect the two copper wires from the
power supply, one to each of the “L1 & L2
Terminals”. See Fig. 7.
The following instructions are for the Quick Touch
Timer. If you have purchased the Time and
Temperature Control with remote or an alternate
control, refer to their “Installation Instructions” now
and then return to “STEAM PIPING”.
c - On the side panel of the steam generator
electrical box, remove the protective label
marked “Remove To Insert Modular
Connector” from the rear modular female
plug. Front plug is for Optional Automatic
Drain. Insert the male plug of the Timer cord
set, retaining tab to bottom, into the female
plug. See Fig. 7 and electrical diagram
Page 7.
d - At the Timer Control location, remove the
protective label from the female connector on
the cord set. Insert the male plug from the
Quick Touch Timer wire, into the female

generator steam pipes.
AVOID A STEAM TRAP
Where the ½ inch iron nipples stick out from the
finished wall, measure one inch along the nipples
from the wall and make a mark. Remove the ½
inch iron nipples used during the rough-in.
Measure the iron nipples from the threads to the mark
and use brass nipples of that length to install the
steam nozzles and escutcheons tight to the wall. The
steam nozzles must be installed with the “tear drop
reservoir” on the top and “steam slot” pointing down.
See Fig. 8.
In a shower or steam room where the steam lines have
been roughed in according to the instructions above,
the installed steam nozzle should be against the wall
and the centre of the steam nozzle should be 12 inches
from the finished floor.
CARE MUST BE TAKEN WHEN INSTALLING THE BRASS
NIPPLES TO ADEQUATELY SEAL BETWEEN THE
NIPPLES AND THE WALL. WE SUGGEST FILLING THE
BACK SIDE OF THE ESCUTCHEONS WITH A SEALER
SUCH AS SILICONE BEFORE PRESSING THEM ONTO
THE WALL. See Fig. 9 .

STEAM GENERATOR START UP
The following instructions are for the Quick Touch Timer. If you have installed the Time And Temperature
Control with remote or an alternate control, refer to their start up instructions now.
1. To start, make sure the electrical supply and the water supply are both in the OFF position. Make sure that all
plumbing and electrical connections are correct.
2. If the drain option is used with a manual shut off, ensure it is in the closed position.
3. Turn on the water supply to the steam generator. No water will enter the unit, as the electricity is still off at this point.
4. Turn on the electrical supply to the steam generator.
5. The display on the Quick Touch Timer has two horizontal bars illuminated. Press the “on/off” button on the Quick
Touch Timer. The display will read “30" minutes. This will energize the contactor coil which will sound an audible
“click” as the contacts close and will in turn energize the water level device. The water entering the appliance will be
audible in the form of several short “spurts” of water, and will stop when the operating water level has been achieved.
If the unit shuts off before water fill is complete, press the “off” (“on/off”) button at the Quick Touch Timer and then
press the “on” (“on/off”) button again to restart the cycle to complete the filling.
Caution: The Steam Nozzle is HOT. Warning: HOT Steam will Burn You.
6. Approximately 2 minutes from energizing the Relax-A-Mist, steam will be entering the steam room. Scalding Caution:
