WARNING : The installation of all the pipes should be operated by qualified plumbers with corresponding operation certificate.

  1. Use joints when connecting pipes.
  2. Use brass pipes or copper hoses only.
  3. Do not use black and galvanized or PVC pipes.

WATER SUPPLY PIPE (1/2″)

  1. Connect hot water or cold water pipes. It had better be hot water pipe with a temperature no more than 70°C.
  2. Install stop valve in the water supply pipe. The stop valve should be installed in a place where it is easily operated in emergency.
  3. Clean the water supply pipe completely before connecting the water pipe to the steam engine.
  4. It is suggested that filter and anti-furring equipment in the water supply pipe.
  5. The water pressure should be at best between 15 and 20 pounds/square inch. If necessary, decrease the pressure accordingly.

STEAM PIPE (3KW/4.5KW PIPE SIZE: 1/2″, 6KW & ABOVE: 3/4″)

  1. Do not install any valves in the steam pipes. The steam can never be obstructed.
  2. Install a brass steam pipe (3kW/4.5kW pipe size: 1/2″, 6kw & above: 3/4″) as connector between the steam outlet and the steam nozzle.
  3. The heat insulation material used to insulate the steam pipe should be resistant to temperature as high as 120°C or higher.
  4. The horizontal part of the steam pipe should be installed inclining to the steam outlet or in the direction of steam engine. Do not bend it in a hape to make sure that the cooled water will not stay in the curved pipe of the steam pipe.
    ATTENTION : Do not install the steam pipe in an upper or lower direction now and then, which will affect the output of steam.

STEAM NOZZLE (3KW/4.5KW PIPE SIZE: 1/2″, 6KW & ABOVE: 3/4″)
Since the steam nozzle and steam outlet are very hot, try to avoid install the steam nozzle in the position which will easily come into contact with the person in a bath in case the steam should splash to scald the user.

  1. Install the steam nozzle in the position 6-12 inches above the ground. If the steam bath is in the bathtub or bathroom, install the steam nozzle 6 inches above the bathtub. If the steam room above adopts materials like acryl or non-heat-resistant sheet, install additional heat insulator.
  2. The steam spray outlet should be installed face down. Wind a few circles of green material belt around the whorl of the steam pipe, install the steam nozzle and tighten with hands.
    ATTENTION : In order to protect the steam nozzle, do not use the spanner or other tools to tighten, use a little soap and water and soft cloth to clean.
