1. Mounting Work Procedure
1. Remove the suction grille, front plate (upper) and rear plate.
2. Remove the rubber bush from the side plate.
3. Align the center of the steam heater with that of the casing, and drill holes on site.
4. To mount the steam spray type humidifier, with the cap and socket mounted to its spray nozzle, fix the
steam spray type humidifier securely to the steam heater.
5. Mount the steam heater thus assembled to the evaporator.
6. Wrap the pieces of asbestos round the joints for steam heater and steam spray nozzle at the portion
100 mm from the joint flange, and fix them tightly by the brass wire. (This measure is to prevent the
steam piping from coming in contact with the casing.)
7. Screw each of the joints into the heater inlet/outlet pipe and spray inlet pipe.
8. Place the suction grille, front plate (upper) and rear plate back in position.
2. Cautions on Mounting Work
¡ The mounting work illustration in the following page shows the right-hand setup of the steam heater.
For the left-hand setup of it, remove the heater upper and lower frames, give the heater 180° turn, re-fit
the frames and fix them securely.
¡ Replace the steam spray nozzle socket with the steam spray nozzle cap and vice versa.
¡ When the steam heater and the steam spray type humidifier are unused for a long period of time, drain
the water inside piping without fail.
