* The black caps are provided for covering the screw heads.
Follow to the instructions shown in the "How to adjust faulty temperature
regulation (Page 10)" shown in the "RSIII Installation Instructions".
* When attaching the reducing valve, make sure that the position
of filter should be higher than original position. The plumbing cover
prevents stop valve from opening and closing smoothly.
* To attach reducing valve smoothly, remove the front cover to
detach the flexible pipe between thermostat and filter.
* Be sure to do this process. Failure to follow this instruction may cause water leakage inside of the plumbing cover leading to corrosion of the
plumbing cover and floor.
* The screw holes of the plumbing cover C are oval holes to allow minor adjustment
of the fixing position.
* The screw holes of the floor fixing brackets are made larger than the fixing screws
to allow minor adjustment of the fixing position.
