Operation
Using the 7-Day Timer
The optional 7-Day Timer allows you to automatically
heat the system without having to manually turn on the
heat.
Before you can use this feature, you must program the
7-day timer, located on the electrical control panel. For
more information about programming the timer, see
the documentation that came with the electronic con-
trol panel.
Each Night:
Follow this procedure each time you use the 7-day
timer (Fig. 24):
1. Turn the CONTROL ON (U) switch to AUT O.
2. Turn the HEAT switch (V) on the electrical control
panel to ON.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure
(page 26).
3.
Relieve the supply unit pressure.
NOTE:
The auto depressurization circuit relieves air
pressure from the supply unit when power is
turned off.
4. Leave the dispense valve open and over an empty
waste container, to relieve pressure that could
build up while the system is heating.
5. Make sure that all material valves are open.
6. Make sure the pump air supply has been turned
OFF.
The system is ready for start-up with the 7-day timer.
