Setting the Alarm
Time Delay Relay
This component determines how soon that the alarm will go off
after a malfunction of the oxygen system occurs. The relay controls
the delay time from two to 300-seconds (five-minutes). We recom-
mend a time delay of about 30-seconds. This gives you adequate
warning of problems in the oxygen system without alerting you to
minor, transient faults.
To change the time delay:
1. Open the electronics compartment (refer to Page 57).
2. Locate the alarm time delay relay (Figure 65).
3. Turn the dial on the relay to the desired time delay setting
(Figure 66).
4. Close and secure the electronics compartment.

The digital readout can be set to display temperature in degrees-
Fahrenheit or degrees-Centigrade. Be aware, however, that the
temperature set dial, the digital displays, and the temperature
controllers in the floor heat controls are calibrated in degrees-
Fahrenheit only. To change the digital readout between F° and C°:
1. Open the filter/fans compartment (refer to Page 58).
2. On the rear of the filter/fans compartment panel, locate the
digital readout (Figure 67).
