Product Manual PSH-30 series Hand Wash Dryer
8.1. Operation
The hand wash and dry cycle is activated when
the “Handwash & Drier” piezo button
is pressed. When the cycle starts, a sequence of soap, warm water and hand dryer
air are dispensed. Note that the water dispensing, and hand dryer functions include a
feature to auto-cancel a cycle that is in operation should the user remove their hands
from underneath the tap head before either cycle has completed its preset time.
A drinking water version of the handwash unit is also available that is operated by a
second piezo button. When pressed, this will operate a secondary water valve to
provide un-heated drinking water. The additional piezo will not activate the full
handwash cycle and the volume of water provided can be controlled in the settings.
8.1.1. Dryer Operation
There are 3 dryer speed settings. The control to adjust the speed is located on the
Control Module LCD control panel. To change the speed, the control module must be
powered up (The fan does not need to be operating). On the LCD control, there is a
small push button labelled ‘Fan Speed’ see figure 30. Press and hold this button to
select the desired setting, this is confirmed by a five-second fan cycle. (It should be
noted that lowering the fan speed will take longer to dry the hands. The dryer is set
as “High” by default.
8.1.2. Air Heater Operation
The PSH-30 hand dryer has an air heater installed to ensure the user dries their
hands in comfortable, high velocity air. The air heater is set to ON by default however
can be turned on or off with the LCD control panel shown in figure 30. Press and hold
button 10 for 2 seconds to switch between the two settings. To show the setting has
been confirmed the correct LED will illuminate.
