READ INSTRUCTIONS CAREFULLY BEFORE FITTING

LOCATING THE GENERATOR
Choose a suitable location for the generator, in any dry space above or below the level of steam outlet eg. in a vanity unit, airing cupboard, adjoining room, loft or cellar, where it is possible to provide suitable water and electrical supplies (see below). The steam feed pipe run should not exceed 5 metres.
DO NOT FIT THE GENERATOR WITHIN THE STEAM SHOWER. MAKE SURE THE EQUIPMENT IS INSTALLED IN ACCORDANCE WITH LOCAL WATER AND ELECTRICAL REGULATIONS

NOTE: It is important that there is unrestricted access to the generator to facilitate electrical plumbing connection and maintenance. The generator must be fitted in the upright position as indicated on the case.

FIXING THE GENERATOR AND STEAM SUPPLY PIPE
The generator may be floor standing or secured to the wall using suitable screws locating into the key hole slots on the back panel. Should it be necessary to drain the generator down it is advisable to wall mount it so that the removable plug in the base of the generator can be used. The steam feed pipe should be 22mm copper tube. There must be no dips in the steam feed pipe on its route to the steam outlet head as these will collect condensation which may block the pipe. Condensation should be able to run on a downhill gradient from the steam generator to the steam outlet head in the shower/bath enclosure if the generator is mounted above the level of the steam head, or run back to the steam generator on a downhill gradient from the steam head to the generator if the generator is mounted below the level of the steam head. The steam feed pipe should be lagged for safety and to minimise heat loss/condensation.

STEAM OUTLET HEAD
Choose a suitable position for the steam outlet head, where it is least likely to touch the bathers feet or legs. If a folding seat is used the outlet may be placed below this and to one side. Drill a 35mm diameter hole, 300mm above the shower tray or bath top edge, and away from any plastic fittings which may be damaged by excessive steam heat. Fit a 22mm male-to-female compression fitting to the steam head, placing the large steam head washer between the fitting and the steam head. Apply silicone sealant on to the reverse side of the steam head washer to seal against the steam head wall and connect the steam head to the 22mm steam supply pipe. Make sure that the dish-shaped essence reservoir in the steam head is level and facing upwards - this will ensure that the steam outlet is pointing downwards and the angle of the outlet will fan the steam back against the wall.

ON/OFF BUTTON
To fit the on/off button, choose a location in the steam enclosure such that it may be operated by the bather when seated. Carefully cut a 40mm diameter hole to allow the button to the pushed back into place. Push fit the 1/4" black air tube on to the button stem while depressing the button head then feed the air tube through the hole making sure that there are no kinks in the tube. Push the on/off button fully home in to the 40mm hole and seal with a bead of silicone on the underside of the flange. Route the air tube back to the steam generator ensuring that there are no kinks or blockages, cut off any excess and push fit the end onto the air tube connection on the service panel of the steam generator.

LED INDICATOR - Does not apply to generators with internal controls
To fit the LED indicator, drill a 12mm hole near the on/off button, apply a small amount of silicone to the rear flange of the LED, feed the wire through the hole back to the generator and plug into the socket on the service panel. Push home the black LED holder into the hole and wipe away excess silicone.

NOTE: It is recommended that the air tube and LED wire are ducted both to protect against damage or heat and facilitate replacement of components if necessary.

The "In-Shower" thermostatic control is supplied with 2 x 5 metre lengths of cable - one with a 3-pin din plug and one with a small Jack plug - both to be connected to the service panel of the steam generator (see the first figure on this page).
The temperature sensor and LED timer indicator are built into the facia of the controller.

The controller must be mounted within the steam shower.

1. Select a suitable location on a smooth flat area not directly above the steam outlet head for the thermostatic control, so that the control is approximately 1.25 metres from the floor and in a location which can be easily read when the steam shower is in use .
   
   
2. Make sure that the controller is within the cable run distance of 5 metres from the generator.
   
   
3. Remove the controller from the plastic back box by undoing the screws in the surrounding bezel and disconnecting the bullet connectors on the wires - red, blue and green to the DIN plug, grey and grey/black to the Jack plug.
   
   
4. Mark and cut a hole 75mm x 75mm to a depth of 40mm to receive the back box which should be recessed into the wall so that the surrounding bezel lies flush with the wall when fitted.
   
   
5. Route the cables with 3-pin DIN plug and Jack plug through the access hole in the back box to the service panel of the generator using suitable cable ducting and plug them into the appropriate sockets.
   
   
6. Reconnect the bullet connectors behind the controller and push the controller into the recess in the bezel. Spread silicone sealant on the back face of the controller making sure that there is enough to give a good seal against the wall on all sides and screw through the bezel to the back box with the two screws previously removed.
   
   
7. Wipe away any surplus sealant from around the bezel, then leave to set for 12 hours to ensure a watertight seal.

EXTERNAL THERMOSTATIC CONTROL WITH CLOCK AND TIMER

This Control must be mounted outside the steam area.
The Helo External Thermostat is designed to be recessed into the wall using a standard double plug electrical back-box. The thermostat has an LCD display showing a 24-hour clock and powered by a built-in rechargeable battery. The start and running time for the generator and preset temperature within the steam room can be set up to 24 hours ahead.
NOTE: The clock time cannot be corrected until the control has been connected to the generator and the generator is turned on (see User Instructions).

FITTING THE BACK-BOX FOR THE CONTROL
The control is connected by a 5-way plug and socket to the temperature sensor and the generator connection cable/din-plug.

1. Remove the control from the back-box by undoing the two screws in the surround and lifting the control clear of the back-box. Disconnect the 5-way plug from the back of the control (see diagram) to free the back-box.
   
   
2. Select a location for the control within 3 metres (10 ft) of the steam room and 5 metres (16 ft) of the generator (the temperature sensor cable is 3 metres long and the generator cable is 5 metres). It is recommended that suitable ducting is used for these cables.
   
   
3. Make a recess 40mm deep in the wall for the back box.

FITTING THE TEMPERATURE SENSOR
The temperature sensor is connected to the 5-way plug and is fitted with an escutcheon to ease installation. The sensor should protrude approximately 5mm from the rim of the escutcheon - this can be adjusted by slackening off the grub screw in the body of the escutcheon. The sensor should be fitted in the steam room at head height when seated but NOT directly above the steam outlet.

1. Disconnect the two white sensor wires from the 5-way plug.
   
   
2. Drill a 15mm dia. hole in the wall to take the sensor escutcheon.
   
   
3. Insert the probe wires through the hole and route back to the control - reconnect to the 5-way plug.
   
   
4. Smear silicone behind the rim of the sensor escutcheon and push the sensor into the hole until the rim is flush with the wall.
   
   
5. Wipe away any excess silicone and leave to set.

1. Route the cable with the din plug back to the steam generator and fit into the socket on the end panel of the generator.
   
   
2. With the 5-way plug connected to the sensor wires and generator cable, feed the plug through the rear of the back-box and reconnect to the socket on the back of the control.
   
   
3. Fit the control into the back-box and screw through the bezel and panel with the two fixing screws.
