Frequently Asked Questions - MS225E Mr Steam

What is the recommended room size for the MS225E?

The MS225E is suitable for steam rooms with a volume of 108 to 161 cubic feet. Adjust for ceiling height above 8 ft and construction materials (add 50% for stone, subtract 40% for acrylic).

How do I install the steam generator?

Installation must be performed by qualified professionals. The generator should be placed on a solid, level surface near the steam room, with minimum 12 inches clearance for servicing. Use brass or copper piping for steam and water lines. Refer to the manual for detailed plumbing and electrical requirements.

What are the electrical requirements?

The MS225E requires a 208-240V, 1-phase supply with a 32-amp breaker (at 240V). Use minimum 8 AWG copper conductors rated 90°C. A separate disconnect switch must be within sight of the generator.

How often should I drain the generator?

In hard water areas, drain the generator every 2 months by opening the manual drain valve after the water has cooled (wait 2-3 hours after use). Alternatively, install the optional AutoFlush® system for automatic draining.

Can I use essential oils with the MS225E?

Yes, with the optional AromaSteam steamhead. Add 1-2 drops of MrSteam essential oil into the recess before turning on the steambath. Never add oil to a hot steam head. Use caution and consult a physician if you have health concerns.

What safety precautions should I follow?

Always supervise children, avoid contact with the hot steam head, limit sessions to 10-15 minutes, and exit immediately if dizzy or uncomfortable. Install the provided warning label inside the steam room. Consult a doctor if pregnant, have medical conditions, or take medication.

What does the status code H20 mean?

Code H20 indicates that the water level has not been satisfied within 5 minutes. Check that the water supply valve is open and the supply line is not blocked. If the problem persists, inspect the water feed solenoid and liquid level control board.

Can I install the control outside the steam room?

Yes. If installed outside, a Remote Temperature Probe (PN MSTS) must be installed inside the steam room to ensure proper temperature sensing. The control cable can be up to 60 ft long.

What replacement parts are available?

Common replacement parts include heating elements (7.5 kW for MS225E), drain valve, safety valve, water feed solenoid, transformer, and liquid level control board. Refer to the parts list in the manual for part numbers.

How do I clean the steamhead and controls?

Use only mild soap and water with a soft cloth. Do not use abrasive cleaners. For the AromaSteam steamhead, avoid pulling on the oil recess. Dry after cleaning to maintain finish.

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.

NOTICE 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

All drawings are for illustrative purposes only

INSTALLING THE ROUND OR SQUARE AROMASTEAM STEAMHEAD (1/2" NPT)

NOTICE A 1½" clearance hole around the steam pipe is needed to mount the steamhead.

STEP 1

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

1. Tub/shower enclosures, install 6 inches above tub top edge.
2. For enclosures with acrylic or other non-heat resistant flooring install Acrylic Shield Part Number 103938.
3. To prevent door seals from deteriorating do not locate the steam head where direct steam emission would contact door seals.
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

Secure a bronze drop ear fitting to a header and run 12 " 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 14 " 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.

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.

CAUTION 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.

POWER WIRING

See "Field Power Wiring" Diagrams (below)

1. Check power voltage. Use 240V rated unit when supply is greater than 208V. (Most homes have 240V, 1PH service). Use 208V rated unit for 208V power.
2. Use minimum 90° C/300V rated insulated copper conductors only, sized in accordance with National Electrical Code and local electrical code for the current in Ampere Chart. If allowed by codes, NM cable may require a larger wire size than as listed on the chart.
3. Connect suitably sized equipment grounding wire to ground terminal provided.
4. Install a separate circuit breaker between supply and unit. Provide a power supply disconnect within sight of the steam generator or one that is capable of being locked in the open position.
5. For single phase units, use two-wire supply source and equipment grounding wire. Neutral (white) wire is not required.

SETTING THE STEAM BATH TEMPERATURE AND DURATION

⚠ WARNING 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

WARNING 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.

WARNING 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.

⚠ WARNING To prevent slip and fall hazards non-skip strips must be installed on the steam room floor.

⚠ WARNING 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.

NOTICE 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 by-products of boiling water.

⚠️ CAUTION Flush a minimum of two-three hours after the control has been turned off to insure that the water has cooled.

⚠ WARNING 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.

⚠ WARNING 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.
