PRODUCTS - Commercial Steam Unit
Installation For 1 Room


COMMERCIAL STEAM GENERATOR EXECUTIVE SERIES (ES) WITH AUTO POWER FLUSH

INSTALLATION INSTRUCTIONS

• All units operate at atmospheric pressure. NEVER install valves or other obstructions in the steam lines (other than factory
  installed). To do so may cause damage to the unit, malfunction or personal injury.
• Always use copper pipe with copper or brass fittings. The use of black or galvanized pipe will cause staining in the steam
  room.
• Always use qualified trades people for the installation of this unit.
• Observe and follow all instruction tags on the machine.
• Use the proper installation diagram for 1-ROOM or for 2Rooms based on your unit specification.
• If you have a 1-Room unit, skip all the instructions that are listed as (2Rooms Only)

STEP 1. LOCATING AND INSTALLING THE UNIT
    1. The commercial steam generator should be located within maximum 50 ft. of the steam room.
    2. It must be located in a clean, dry location (e.g. mechanical room). It is not designed to operate in a location that is
        wet, damp or may get splashed with water or chemicals which could cause a shock hazard and will cause serious
        damage to the unit voiding all warranties.
    3. Before installing the unit, have in mind that you need water line and drain hole close to the unit, also you will need
        to run power line to the unit.
    4. All areas that may be exposed to frost or high temperature must be avoided e.g. attics or unventilated rooms
        where temperature can reach 120 0F (50 0C) or more.
    5. The steam unit should be shelf or bench top mounted in an area that allows easy service access. We recommend a
        shelf height of 36” – 45”. Installation in the wall or under the ceiling is not recommended.
    6. The unit must always be installed on a level surface with the steam outlets and electrical box(es) at the top.
    7. Face the front (access panel) out from a wall so that it may be readily removed to access the fuses and other
        components of the unit for maintenance purposes. Allow a minimum of 4” to 8” clearance from the wall on each
        side of the unit for easy access and ventilation.
    8. NEVER mount the unit with one (1) side against a wall.
    9. Always mount the unit on flat and level surface. Do not set into an external frame.

STEP 2. INSTALLING THE STEAM VALVES


(2Rooms Only) SKIP THIS STEP IF YOUR UNIT IS SERVING ONLY 1 ROOM
    Two steam valves with necessary fitting and connectors are provided inside the package. They must be installed on the steam outlets on top of the unit.
    1. Remove the bubble wrap the from two steam valves.
    2. Connect them on the top of the machine using the labels on the machine as your guide e.g. the “steam out”
        stickers are located under the steam valves.
    3. The pressure relief valve sticker is located under the pressure relief valve.
    4. Tighten down the compression fittings on top of the tank.
    5. Remove the snap ring on top of the valve stem and place the solenoid coil(s) on the stem(s). Coils and valves are
        labeled.
    6. Replace the snap rings.
Note:
    Always have these solenoid coils properly installed before applying power to the machine.



STEP 3. INSTALLING THE CONTROL BOARD
    1. Choose a location that is both clean and dry.
    2. Choose the height as you comfortably have access to the Board in future.
    3. Be sure that it is not located in an area that is close to a steam line or a hot water line or a source of heat; beside
        or on top of the steam generator; under any cold water lines, drains or other pipes that may sweat and leak
        condensation onto the box.
    4. Remove the front cover from the box to expose the control board.
    5. There are 4 exposed screw holes in the back of the box that you will use for wall mounting.
    6. Mark this screw pattern on the wall in your chosen location.
    7. Drill the holes and mount on the wall.
    8. Take extra care around the wires and control board so as not to scratch, dislodge, bend or otherwise damage the
        board or wires.
    9. Replace the box cover to keep the contents clean.



STEP 4. PLUMBING

All units come factory equipped with compression connections and unions. Always use these connectors.


INSTALLING THE STEAM LINES
The steam outlets are two 3/4" copper pipe compression fittings on top of the unit, which you will immediately expand into a 1" line. Run the steam lines from the steam outlets (or steam valve outlets in 2 Rooms units) to steam rooms. Always install the steam lines so they drain back to the machine and/or to the steam heads. Never have a low spot that will accumulate condensation. Insulate exposed steam lines with fiberglass insulation to prevent steam heat loss.

Exception:
(2Rooms Only)
If 2 rooms are of different sizes or If 1 room is closer to the steam unit and the other more distant. A manual steam shut off valve can be installed near the unit in only one of the steam lines to the smaller or closer room. This will allow the continuous steam to be properly distributed between the 2 rooms by forcing more of it to the larger room when the valve is partially closed.

Do not use a restriction in any other line.
If only one pipe Runs to each room, do not restrict a single steam line. Branch into 2 smaller lines and restrict only one line, e.g. a 3/4" line to two ½" lines with a restriction in one ½" line.

Notes:
    1. ½” steam lines are not recommended for any of the units.
    2. For steam line runs of 50 ft or more, contact the manufacturer
    3. Never use foam type insulation.

INSTALL THE DRAIN LINE
The drain valve is located on the front of the unit and has a ¾” fitting. Using an adapter connect a 1” copper pipe to the drain valve. Run this pipe with a down slope to the floor drain, because the drain system is a gravity drain and there is no pressure behind the drain valve to flush the water except gravity.

WATER INLET LINE
A sediment filter is installed on the ¼” water inlet line. Install a manual shut off valve on the 1/4" copper pipe and connect it to the ½” water supply line. If the water supply pressure is more than 40 PSI, install a pressure reducer (35 to 40 PSI) on the water supply line. If you are connecting to a softener or R.O. system, use the instructions included with this equipment to connect into the water supply. Set up the softener according to specific instructions included with it.

POWER FLUSH LINE
The Power Flush solenoid is installed on the ½” line on the front of the unit. Using a manual shut-off valve, run a ½” copper pipe to the water supply. If the water supply pressure is more than 40 PSI, install a pressure reducer (35 to 40 PSI) on the water supply line.

Notes:
    1. Always install independent shutoff valves on all incoming water lines to the unit, one to the water feed (1/4” pipe) and
       one to the power flush (½" pipe).
        Install a Pressure Reducer to reduce the incoming water pressure on the power flush valve and inlet solenoid valve to
       between 30-40 P.S.I.
    2. Flush the 1/4" feed line to the drain or a bucket prior to connecting it to the unit, otherwise the copper
       debris will clog the Water Inlet Valve and the Power flush Valve.


STEAM BLOW-OFF LINE
Install a safety pressure relief valve (5 to 10 PSIG) on one of the steam lines and run a ¾” copper pipe from its outlet to the floor drain. The 2 ROOMS units come with a factory installed pressure relief valve and you just need to run the pipe to floor drain.

STEAM HEADS
The steam head(s) should be located in a safe area away from people’s feet and legs. They should be as close to the floor drain as possible.
The steam head(s) should be placed between 6" to 12" up from the floor with the slotted side facing down. They may be grouped together or spread throughout the room. Never place the steam head(s) high on a wall.

STEP 5. ELECTRICAL INSTALLATIONS

Have a qualified electrician to connect the unit to power source. The wattage and voltage are listed on the serial plate on the side of the unit. Make sure that your power source voltage and amperage capacities match the unit.

POWER CONNECTION
You will need a Circuit Breaker and A Fuse Disconnector Switch and sufficient length of Cable to install the Power line. Select the appropriate parts according to the electrical characteristics of the Steam Generator and Local Electrical Codes.
Install a Circuit Breaker in Power Distribution Panel and connect it to main power. Run a cable from Circuit Breaker to a Fuse Disconnector Switch that will be installed on the wall beside the Steam Generator. Connect L1 (red), L2 (black) and/or L3 (blue) wires in the Power Junction Box to the Fuse Disconnector Switch. Connect the Ground Terminal in the Power Junction Box to the ground. This machine has no neutral connection.
The power to the unit must be uninterrupted on a day-to-day basis. This allows the control board and timer to function properly.

INSTALLING THE TEMPRATURE SENSOR PROBE
The Sensor Probe should be installed into the wall approx. 6" below the ceiling and in Opposite corner of the room from the steam heads. The Sensor head must be exposed into the room from the wall approx. 1" out, and sealed with rubber or silicon gel. It must always have free air flow around it to prevent sensing radiant wall heat (Above the door is a good location). A guard that allows free airflow may be placed over the bulb.

CONNECTING THE SENSOR PROBE TO THE THERMOSTAT
The Sensor Probe is supplied with a 6 ft wire. If the distance between the steam room(s) and the Thermostat(s) (which is/are installed on the Steam Generator) is more than that, run a cable (1 pair 22AWG, shielded) from the thermostat to the Sensor Probe and connect it to the sensor wires.

STEAM COTROL OPTIONS
BASED ON THE USER’S REQUIREMENTS THE UNITS ARE DESIGNED WITH DIFFERENT CONTROL OPTIONS. Check your unit Work Order Sheet and the parts that are supplied with unit, and then use the proper instruction in this section. Your unit may not have some or all of the options that are described below.

30 OR 60 MINUTES SHUT OFF TIMER
Install the 30 or 60 minutes Timer outside the steam room beside the door. Run a cable (2x14 AWG) from this timer to the Power Junction Box on top of the Steam Generator and connect it to the labeled wires accordingly.

IN ROOM TOUCH TIMER
Install the Touch Button inside the steam room into the wall, away from steam and water dripping and accessible for users to use as a Start/ Stop Button. Seal the flat side on the wall with Silicon Sealing. Connect the female end of the Connector Cable to the rear end of the Button and run the cable to the Touch Timer in the Black Box, which is attached to the Steam Generator by a flexible conduit. Connect the male end of the Connector Cable to female connector on the box.

AIR SWITCH
Install the Air Switch Cylinder inside the steam room into the wall, away from steam and water dripping and accessible for users to use as a Start/ Stop Button. Seal the front side on the wall with Silicon Sealing. Insert one end of the Plastic Tube provided with the switch into the back of the cylinder and Run it to the Steam Generator. Insert the other end of the Tube to the Air Switch, which is in the Power Junction Box on top of the Steam Generator.

SCENT DISPENSER (OPTION)
Read the dispenser Instruction manual that is provided with this document separately before installing.
Scent dispenser pumps the fragrance-wintergreen, eucalyptus…- from the bottle into the steam line. Install the scent pump beside the steam generator and connect its adopter to the power source.
The scent tubing starts from the Fragrance Bottle and its black portion will be mounted on the scent pump wheel. Then it ends to the Saddle Valve, which will tap into the steam line.

INSTALLATION INSTRUCTION FOR SELF PIERCING SADDLE VALVE
