Basic Operating Procedures
Use the following controls for filling tub and
showering patients. The Whirlpool and cleaning
system are described separately.
Controls
The 900 Bathing System control panel and bathtub
are made of fiberglass. It has a thermoscopic mixer
(2) for the bathtub filling and the patient shower.
The thermoscopic mixer regulates water valve
temperature for the bathtub fill and the patient
shower.
To calibrate the thermoscopic mixer, see enclosed
product manual.
In addition, there are shut-off valves for the tub fill
(4) and patient shower (9).
The thermometer (3) measures bathtub filling water
and patient shower temperature in C.
The temperature probe is located close to the
thermoscopic mixer (2) to provide an accurate
reading of water temperature as the bathtub fills.
By monitoring the thermometer, you can precisely
regulate water temperature with use of the
thermoscopic mixer (2) as the tub fills or when the
patient shower (11) is used.
Height of the tub is adjusted with the tub up/down
controls (1). The tub can be adjusted to any level
from 600 mm (24”) to 1000 mm (40”) above the
floor.
