Amerec steam generators are tested by Intertek-ETL Laboratory. The steam generators come assembled and ready for installation. Check that the size and rating of the generator is suitable for your application, refer to

CAUTION

Electrical grounding is required on all

AMEREC Steam bath Generators.

All electrical supplies should be disconnected when servicing generator.

All wiring must be installed by a licensed electrical contractor in accordance with local and national codes.

All plumbing must be installed by a licensed plumber in accordance with all applicable local and national codes.

AX series generators are for indoor use only.

AX series generators are not for space heating purposes.

Be certain that steam bath enclosures are properly sealed to avoid water damage from escaping steam. It is recommended that 100% silicone caulk be used to seal all pipes and fittings.

Steam must be prevented from escaping into the wall cavity.

Never shut off the water to a steam generator that is in use.

Electric Shock Hazard - High voltage exists within this equipment. There are no user serviceable parts in this equipment.

the AX Steam Room Sizing and Rough-in Guide (Amerec doc 4211-36).

The AX steamers may be connected as a ganged system where one Steamer controls one or two other steamers.

Bath controls connect to the primary steamer and the primary steamer connects to the second steamer (and third steamer, if installed). This provides more power for large rooms and light commercial use. Note : An Elite control is required with a ganged system!

See appendix to this document for details.

We recommend choosing steamers which are closely matched in power. The highest kW steamer should be the primary unit. Each steamer should have its own automatic drain.

For commercial use, we recommend checking with your local inspectors to confirm the AX system is acceptable for your use. Many jurisdictions will require an ASME boiler for commercial use: AX steamers are not boilers .

Note : The AX steamer may be configured for single or three phase power during installation

An exhaust fan installed outside the steam room is strongly recommended.to remove excess steam from the bathroom or shower area.

AX INSTALLATION AND SERVICE INSTRUCTIONS

SECTION 1: MOUNTING THE STEAM GENERATOR (continued)

1. WALL MOUNTING: Remove the side cover. Note the location of the mounting holes on the back of the generator. The screws must set directly into studs or equivalent supports. Drill pilot holes on 14-1/2”

(368 mm) centers and install the two #10 1½" screws, provided.

See at right.

a) Carefully hang the generator on the two screws. Tighten the screws. b) The generator may be further secured with two screws mounted on the same 14-1/2” (368 mm) centers as shown. c) Replace the front cover with its four screws.

2. FLOOR MOUNTING: a) In general, the width of the unit allows it to sit on a shelf, across the ceiling joists or on a floor. The generator must be restrained from moving. Normally, the piping will provide adequate support. If not, additional support must be provided. b) All floor installed generators must provide for routine draining of the tank and for draining the safety valve’s outlet.

SECTION 2: WATER QUALITY REQUIREMENTS

WALL MOUNTING

14.5” [368 mm]

14.5” [368 mm]

The nature of a boiler or steam bath generator requires testing of the feedwater to avoid potential high concentrations of impurities which can cause a deposit or scale to form on the internal surfaces. This deposit or scale can interfere with the equipment's proper operation and even cause premature boiler or generator failure. Concentration of impurities is generally controlled by treating the feedwater and or "blowing down" the generator or boiler when it is not heating. The "blow down" process involves removing a portion of the tank water with high solid concentration and replacing it with makeup water.

This is particularly important in areas with high calcium levels and other water quality problems. Calcium build-up can cause poor steamer performance and damage the heating elements!

Be especially careful to prevent foaming in the steamer’s water!

Foaming water will affect the water level measuring systems in steamers and boilers, causing operation problems and possibly leading to early element failures!

To insure proper operation, the water supply should be tested prior to operating the equipment. There are several treatment processes which can be used if you have a problem with hard water. A local reliable water treatment company can recommend the appropriate treatment if required. The recommended feedwater quality is listed on the next page.

1. INSTALL WATER LINE Connect a cold water line to the generators water valve. The valve input is 3/8” NPT. A shut-off valve should be placed in the line for each generator to allow easier servicing later, if needed, and for emergency shut-off. Make sure the shut-off is open, providing water to the generator before first turning the on.

IMPORTANT

• Water pressure required: 20-100 psi (138-690 kPa)

• If the generator is mounted in a place difficult for the homeowner to access, the water supply shut-off valve should be located where it can be quickly accessed in an emergency.

• Do not use a saddle valve or saddle fitting for the water shut-off valve.

• Flush water supply line before final hookup.

2. INSTALL STEAM LINE a) At the generator: Install a 1/2" male NPT sweat adapter directly into the tank. Install a 1/2" union in the steam line to allow easy disconnection for later servicing. Note : There must be no valves, shut offs or restrictions in the steam line!

b) Run the 1/2" copper steam line from the generator to the steam room. Refer to SECTION 2: MOUNTING THE

STEAM GENERATOR and Diagrams 3a and 3b.

• The steam line must slope to allow condensation to drain into the tank or room.

• There must be no dips in the steam line. Low areas may collect condensation and cause faulty operation or cause hot water to spit into the room. c) The steam line should enter the steam room 18” (460 mm) above the floor or at least 12” (305 mm) above a tub rim or ledge. The steam line outlet should be at least 6” (150 mm) from other steam heads to either side and

7. CONNECT AUTODRAIN: Connect the autodrain wires through ½ in conduit (provided) and secure the conduit to the chassis hole. Connect the drain wires to the terminal block provided next to the steamer’s ground lug. See diagram 8.

SECTION 4: WIRING INSTRUCTIONS

ALSO SEE ELECTRICAL INFORMATION CHART AND WIRING DIAGRAMS

1. ELECTRICAL ROUGH-IN: Size wire for the generator as required by local or national codes. See the electrical information on page 13 for further information. Use copper wire only. Leave 4 ft (1,2 m) of slack wire at generator location for finish hookup. Connect the generator to a dedicated circuit breaker. A GFI device is usually not required by safety agencies. One may be installed if required by local codes or the owner. A GFI device will tend to nuisance trip due to heater element aging.

a. Route the copper supply wire with appropriate strain relief through the hole marked POWER ENTRY. b. Connect the supply wires to the power terminal block as indicated on the wire diagram for your voltage and phase. This may require moving factory installed jumper. Do not change the steamer’s internal jumpers or wiring. Only the supply wiring side of the terminal blocks require configuration by the installer.

c. Connect the Earth wire to the copper Earth ground lug. d. Cover the supply wires inside the steamer with a protective mesh or similar material to protect them from water valve heating.

2. ELECTRICAL INFORMATION The AX steamers are available in 2 basic versions, one for 208V (intended for

208VAC single and three phase for North American use) and 240V (intended for all other installations. The 240V models are rated at 240VAC and may be used on 208 to 240V single phase Line-to-Line or 208 to 240V~N (Lineto-Neutral) or 208V to 240V three phase Delta without Neutral or for Y-connected three phase 380 to 415V~N3.

All Units are factory wired for single phase installation. The installer may change the input to three phase or three phase with Neutral during initial installation (see the wiring diagrams on page 18).

The National Electrical Code (NEC) limits a steamer’s current to 48 Amps so in some cases, two separate power supplies are required: AX11 & AX14 208V single phase and AX14 240V single phase.

See page 18 for Mains Wiring Details. Note: jumpers shown are supplied with the steamer .

AX INSTALLATION AND SERVICE INSTRUCTIONS

SECTION 5. BATH CONTROLS

1. TEMPERATURE SENSOR CABLE ROUGH-IN (low voltage) It is required that the sensor be mounted in the steam room, but not directly over the steam dispersion head or near the door. The sensor should be located in a wall 6” (150 mm) below the ceiling but no more than 7 ft (2,1M) above the floor. String the sensor cable from the sensor location through 1/2:” (12 mm) holes in the wall studs or ceiling joists to the generator location. Drill a clean

7/8: (22 mm) hole through the steam room wall at the sensor location. Leave 12” (305 mm) of slack at the sensor location. See Diagram 9.

DIAGRAM 9

Note: Do not staple through or damage cable.

Use factory supplied cables only .

INSTALL THE TEMPERATURE SENSOR ASSEMBLY inside the steam room. A 7/8” (22 mm) hole should already be in the steam room wall with the cable ready.

Make sure the sensor is not directly over the steam outlet

SILICONE

Run a light bead of silicone around the back surface of the sensor and slide it into the wall with the metal sensor tube pointed down. Tape the sensor to the wall until the silicone has set-up.

Connect the steam generator end of the cable to the short adapter cable (4-pin modular plug to 2 pin sensor cable jack) and plug the adapter into the NTC jack on the steamer board (located along the top edge of the steamer’s circuit board, at the far left of the 4 black jacks). ( See diagram 10 )

2. CONTROL CABLE ROUGH-IN (low voltage) A 50 ft (15,2 m) 4 wire Cat5 cable is provided for connecting the

PURE 2.0 or ELITE control to the steamer. The PURE 2.0 and ELITE controls may be mounted inside or outside the steam room. String the control cable from the control location through 1/2” (13 mm) holes in the wall studs or ceiling joists to the generator. Note: Do not staple through or damage cable. Use factory supplied cables only .

Run the cable end through a 1” (25,4 mm) hole in the wall at the control mounting location. One PURE 2.0 or ELITE control is required; a second may also be connected. Controls should typically be mounted 5 feet (1,5 m) above the floor outside the steam room or at a height comfortable for viewing inside the room while having a steam bath.

See control mounting section for more information.

3. INSTALL THE ELITE or PURE 2.0 CONTROL inside or outside the steam room using the control cable installed in section 5, step 4. If mounting to a smooth, flat wall, the adhesive pad provided will work well to mount the control and seal the cable hole. The adhesive will stick to the wall quickly so be sure to accurately place and level the control before attaching it to the wall!

Your Elite control comes with a plated trim piece; many finishes are available. These trim pieces also fit the Pure 2.0. Contact Sales or Support for further information. If using a trim piece, slide the plated trim piece over the back of the control before mounting the control. Mounting the control will keep the trim in place.

Recommended: Locate controls 5 ft (1,5 m) above floor outside the steam room. Controls mounted inside the room should be set to a height comfortable for use while having a steam bath.

Amerec document number 4211-119

SECTION 1: GENERAL INFORMATION

Amerec Steam Generators are listed by ETL. The steamers come assembled and ready for installation. Check that the size and rating of the steamers are suitable for your application; refer to Steam Room Construction and

Generator Sizing Guide (Amerec document 4211-36).

Amerec AX Steam Systems consist of one AX steamer acting as a “primary” steamer which may control one or two other AX steamers. The sole purpose of ganging steamers is to increase the volume of steam generated without using multiple controls. The primary steamer controls the secondary steamer(s) through an Amerec control cable. Cables are available only from Amerec.

All controls must connect only to the primary steamer! An Elite control must be connected to the primary steamer!

IMPORTANT

An exhaust fan installed outside the steam room is strongly recommended to remove excess steam from the bathroom or shower area.

MOUNTING

The Amerec Steam Generator can be hung on a wall or set on its base. The best mounting location will satisfy all or most of the following conditions:

1.

The steam line should slope to allow condensation to drain into the steam room.

2.

The steam line should be less than 20 ft (6m) long; 10 ft (3m) is preferred. Steam lines over 20 ft (6m) long should be insulated.

3.

The mounting location should minimize the number of bends and elbows in the steam line.

4.

The steam line should enter the room 18” (460 mm) above the floor or at least 12” (305 mm)above a tub rim or ledge .

Electrical grounding is required on all Steam Generators.

All electrical supplies should be disconnected when servicing a

Steam Generator.

All wiring must be installed by a licensed electrical contractor in accordance with local and national codes.

All plumbing must be installed by a licensed plumber in accordance with all applicable local and national codes.

Steamers are for indoor use only.

Steamers are not for space-heating purposes.

Be certain that steam bath enclosures are properly sealed to avoid water damage from escaping steam. It is recommended that 100% silicone caulk be used to seal all pipes and fittings. Steam must be prevented from escaping into the wall cavity.

Never shut off the water to an appliance that is in use.

Use correct size and type of power wires and circuit breakers to meet electrical codes. Leave 4 feet (1,2 m) of slack wire at generator location to finish hookup.

Connect each generator to a dedicated circuit breaker.

2 ELECTRICAL FINISH

At the generator, route the copper supply wire with an appropriate strain relief through the hole marked POWER ENTRY. Connect the supply wires to the power terminal block. Refer to the wiring diagrams to determine your connection points and the necessary jumper connection. Connections can be varied to use either single phase or 3 phase or 3 phase +Neutral. Connect the earth ground to the ground lug (green screw).

Notes :

• Two power circuits are required for 208V AX11s and for 208V and 240V AX14s.

• Supply voltage must be 200V or higher. 240V models may be used with available voltages to 240V (and 380V-415V~3N).

• Use copper power wire only! All wire is to be UL Listed, 300V 75°C minimum unless otherwise specified.

• A GFI device is not required by UL or NEC. One may be installed if required by local codes or the owner.

A GFI device will tend to nuisance trip due to heater element aging.

CONNECT STEAMERS TOGETHER a) Connect an AX Systems cable from one of the Primary steamer’s control jacks to one of the secondary steamer’s control jacks. Repeat for the third steamer, if installed. Do Not use an Elite or Pure 2.0 control cable - a special 12 ft (3,7 m) cable is required from Amerec. Note: We recommend system steamers be of similar wattages and, if not the same, the largest wattage should be in the primary steamer. See diagram below.

CONNECT CONTROLS

Connect controls only to the Primary steamer. Refer to the individual steamer instructions for requirements.

SECTION 6: OPERATIONAL TEST After controls and system generators are connected

Refer to Section 6 of the single steamer installation instructions and start the system steamers.

When the Pure 2.0 or Elite control is used to start a steam bath, all steamers in the system will start together and turn their heating elements on and off at the same time while there is enough water in their tanks.

Each steamer will control its own water level during the bath.

If AutoDrain is installed: Each steamer will control its own drain and drain one hour after the bath stops.

! Do Not connect steamer drains together.

! Do Not connect steam outlets from different steamers to the same steam piping.

THE SYSTEM IS NOW READY FOR OPERATION.
