Installation, Operation & Maintenance Manual

WATER QUALITY INFORMATION
For optimum results, the water supply should be tested prior to installation. If the mineral content exceeds the following recommended limits, various external treatment processes are recommended to correct the problem.
An analysis of the on-site water must be made by a recognized and reliable water treatment company to ascertain the existing condition and treatment required.
Poor water quality can affect efficiency or result in steam generator damage. Water contains impurities in solution and suspension. These impurities concentrate in the generator. The concentration of these impurities increases as more feedwater is introduced into the generator and steam is produced. If the suspended solids are allowed to concentrate beyond certain limits, a deposit or “scale” will form on the generator internal surfaces. This deposit can interfere with the proper generator operation and cause generator failure. The concentration of these impurities is generally controlled by the water quality and by periodic draining of the generator.

RECOMMENDED FEEDWATER QUALITY
Hardness, ppm 8 ­ 85 (~0.5 ­ 5 gpg) P-Alkalinity, ppm 85 ­ 410 (~5 ­ 24 gpg) T. Alkalinity, ppm 200 ­ 500 (~7 ­ 0 gpg) pH (strength of alkalinity) 8.0 ­ 11.4
Every 2 months, or more often in “hard” water areas, the manual drain valve should be opened fully flushing out accumulated materials, salts and other particles which are natural by-products of boiling water. The optional AutoFlush System feature automatically drains the MrSteam® generator following each use. A time delay allows the water to cool down (about two hours) before it drains by gravity for a safe and gentle operation.

LOCATING THE STEAM GENERATOR
Select a location as near as practical to the steam room.
Typical locations include: closet, vanity cabinet, heated attic or basement.

The standard length of the cable for connecting the control to the steam generator is 30 feet. The steam generator and control must be located accordingly. A 60 foot cable is available as a special order part for iTempo® and AirTempo®, PN 103990-60 and PN 104117-60 for iSteam®. The maximum cable length is 60 feet. IMPORTANT NOTE: The control cable should be run in a dedicated 1″ conduit to facilitate installation and service.

Check local plumbing code for receptor, trap and vent requirements. DO NOT connect Drain line and Safety Valve line together. Unit drains by gravity.
DO NOT plumb the generator drain and condensation pan drain together in such a way that will cause drain water to back into condensation pan. DO NOT drain into a steam enclosure or any location where accidental contact with drain water may occur. In the event of a power failure the AutoFlush System valve will open and may discharge boiling water causing a scalding hazard.

SAFETY VALVE (3/4″ NPT)
Where permitted by local codes, provide an outlet plumbing connection for safety valve.
To insure proper and automatic safety valve operation: DO NOT connect a shut off valve or a plug at safety valve outlet. DO NOT connect a shut off valve or any obstruction in steam supply pipe. DO NOT connect the safety-valve output into the steam piping.
CONDENSATION PAN
MrSteam strongly recommends the use of a condensation pan in the unlikely event of a plumbing leak. Check local plumbing codes for receptor, trap and vent requirements. Condensation pans drain by gravity. The condensation pan is equipped with an integral 3/4″ fitting. See page 17 for additional condensation pan installation information.
Do not plumb the generator drain and condensation pan drain together in such a way that will cause drain water to back into condensation pan.

INSTALLING THE ROUND OR SQUARE AROMASTEAM STEAMHEAD (1/2″ NPT)
A 1 1/2″ clearance hole around the steam pipe is needed to mount the steamhead.

Use Teflon® or equal sealant on
pipe threads

STEP 1

Steam Piping

Locate steam head 6-12 inches above floor, except for:

1. Tub/shower enclosures, install 6 inches above tub top edge.

For

enclosures

with

acrylic

or

other

non-heat

resistant

flooring

Apply with silicone or equal sealant as required for

moisture seal.

3.To prevent door seals from deteriorating do not locate the steam

head where direct steam emission would contact door seals.

Oil Well

4. To reduce noise, do not locate steamhead within 12″ from a wall.

STEP 2 Install steamhead with the oil well facing up as shown. Hand tightening is sufficient when teflon or equal pipe thread sealing compound is used.

STEP 3

STEP 3 Secure a bronze drop ear fitting to a header and run 1/2″ copper steam piping from the steam generator to the drop ear fitting. Install a temporary nipple (6″ or longer) in the drop ear fitting to locate the steamhead after the wall is finished.

STEP 4 After the wall has been finished, mark on the nipple where the surface of the wall is. Remove the nipple and measure the portion that was in the wall (the end to your mark). Subtract 1/4″ from that dimension and select a brass nipple of that length to finish the installation.
STEP 5 Wrap teflon tape around the threads of the new nipple and screw the nipple into the steamhead. Do not use wrenches or tools which would damage the steamhead’s finish. Wrap teflon tape around the threads of the nipple and screw the nipple and steamhead assembly you just made into the drop ear fitting in the wall. The steamhead should be flush with the wall and the well must be facing up.

STEP 4

1/8″ minimum clearance required when Acrylic Shield is used. See installation instructions provided with the Acrylic Shield.
End of pipe to be recessed 1/4″ (without Acrylic Shield) 1/8″ (with Acrylic Shield)
Drop Ear Fitting

IMPORTANT NOTE: DO NOT disassemble steamhead. MrSteam’s steamhead is shipped fully assembled and requires no additional assembly. To preserve steam head finish, DO NOT use wrench or other tools to tighten. DO NOT use abrasive cleansers or chemicals. Use only water with mild soap and a non-abrasive sponge.
Because the steam head and direct steam emissions are very hot, locate the steam head where incidental contact by bather with the steam head or direct steam emission cannot occur.
Consult with supplier of acrylic, fiberglass and other non-heat resistant enclosures for recommended steamhead location. Use Acrylic Shield PN 103938 (round) or PN 103938SQ (square). See instructions provided with steam shield.

OPTIONAL AUTOFLUSH®
Box Contents AutoFlush Valve with Cord Installation Instructions
OPERATION The optional AutoFlush System feature automatically drains the MrSteam generator following each use. A time delay allows the water to cool down (about two hours) before it drains by gravity for a safe and gentle operation.
If the Express Steam® option has been installed, the AutoFlush will drain for ten minutes then refill with fresh water to begin the pre-heat cycle.
INSTALLATION INSTRUCTIONS
1. Plumbing to be performed by a qualified plumber and shall be in accordance with applicable national and local codes. Unit drains by gravity. A drain line that is lower than the AutoFlush® assembly must be available. The AutoFlush System valve outlet is 1/2″ NPT. Check plumbing code for receptor, trap and vent requirements.
2. Use copper or brass nipple 1/2″ NPT x 31/2″ or longer (not supplied) to connect AutoFlush valve to the Drain Valve (follow arrow on AutoFlush valve for flow direction, arrow should point away from generator’s drain valve).
DO NOT REMOVE THE DRAIN VALVE Removal may cause equipment and property damage. If there is not enough room for the valve, an elbow and a short nipple (not provided) can be added.
3. Open Drain Valve (handle must be aligned with brass nipple).
4. Connect the AutoFlush System cord connector to the three pin connector as shown.
5. The AutoFlush valve must be installed within the orientation range shown. DO NOT drain into a steam enclosure or any location where accidental contact with drain water may occur. In the event of a power failure the AutoFlush System valve will open and may discharge boiling water causing a scalding hazard.
SWEAT FITTINGS When using sweat fittings use only tin base solder with a melting
point below 600 degrees F. DO NOT overheat. Ends of water supply tubing must be thoroughly clean for a minimum distance of 1″ from ends. DO NOT remove valve cover.
TO CHECK OPERATION 1. Turn on MrSteam and allow tank to fill with water. 2. Turn off MrSteam control. Water should stay in tank. 3. Turn off power at the panel box. Water should discharge from
tank. 4. Turn on power at panel box. 5. Repeat

Installation, Operation & Maintenance Manual

SETTING THE STEAM BATH TEMPERATURE AND DURATION
Set the steam bathing temperature according to personal preference, however it is highly recommended to begin steam bathing at a low temperature setting to gauge comfort and safety levels. Set duration to a maximum of 10 minutes to gauge comfort and safety levels. This will allow the steam generator to heat up and begin producing steam.
SAFETY AND OPERATING INFORMATION
DO NOT install or use any iSteam®, AirTempo®, iTempo/Plus®, iTempo®, HomeWizard® or iGenie® controls without reading and understanding the MrSteam steam generator Installation and Operation Manual. Failure to read and understand these instructions may result in an inoperative or hazardous installation.
The peel and stick warning sticker located in this manual must be read and permanently affixed in a conspicuous location near the steam room. Failure to read and affix this warning sticker in a conspicuous location may result in serious injury or death.
If an iSteam, AirTempo, iTempo or iTempo/Plus control is installed outside the steam room a Remote Temperature Probe (PN MSTS) must be installed inside the steam room per-installation instructions supplied with the Remote Temperature Probe. Failure to install according to instructions will result in an inoperative control and overheating of the steam room.
To prevent slip and fall hazards nonskip strips must be installed on the steam room floor. DO NOT alter or modify any MrSteam product. Doing so may result in an inoperative or hazardous installation and will void the UL listing and warranty.
IMPORTANT NOTES: Malfunction due to power spikes, lightning, fire, freezing or flooding is not covered under the warranty.
Discontinue use of the steam generator or control if the steam generator is damaged or otherwise not functioning properly. Doing so may result in an inoperative or hazardous condition.

CARE TIPS FOR ALL CONTROLS AND STEAMHEADS
1. Use only mild soap and water on a soft cloth to clean the control and steamhead. 2. DO NOT use abrasive cleansers. 3. If the decorative cover is damaged on the iTempo or iTempo/Plus call MrSteam technical service for replacement parts.
Replacement of the decorative covers requires removal and reinstallation of the control from the mounting surfaces.
STEAM GENERATOR MAINTENANCE
MrSteam steambath generators require little maintenance. Other than periodic draining, maintenance procedures are minimal. Every 2 months, or more often in “hard” water areas, the manual drain valve should be opened fully flushing out accumulated materials, salts and other particles which are natural byproducts of boiling water.
Flush a minimum of two-three hours after the control has been turned off to insure that the water has cooled.
Draining immediately after a steam cycle may expose PVC and other piping to high temperature water. Check local codes. The unit will refill automatically when the control is activated again. In areas of hard water, a MrSteam AutoFlush® system is recommended for generator longevity.
Failure to allow the water to cool will expose the equipment and user to scalding water and cause property and personal injury.
IMPORTANT NOTE: The model and serial number is printed on the data plate on the front of the steam bath generator.
