APPENDIX C
• Does the start-up time seem too long?
If the start-up time seems too long, you can go
directly to Step 3: EVAPORATOR OR COMBUSTION
OPERATION. Proceed as follows.
From the page in AUTOMATIC mode (Illustration 5 and 13):
1. Press the [RUNNING MODE TRANSFER] key at the
top left of the screen.
2. Then authorize the change by pressing the [YES]
key in the pop-up window that appears at the top
left of the display (Illustration 14).
5.3 Step 3: EVAPORATOR OR COMBUSTION OPERATION
The OPTIFLAM TM then switches on. The program constantly adjusts the speed of the combustion air fans to
maintain the set temperature.
If the set point temperature can no longer be maintained, a request for a combustion chamber fuel reload is
indicated by two warnings:
• the blue light on the touch screen housing flashes,
• and the message "RELOAD" is displayed under the LAPIERRE identifier on the operating display.
Then proceed with the following step No. 4.
5.4 Step 4: RELOADING WITH COMBUSTION CHAMBER FUEL
Follow the steps below to reload the combustion chamber fuel:
1. Press the blue light, which is also a push button, or the "RELOAD" message on the operating display to signal
that a reload will be performed.
2. The blue light will go out and the OPTIFLAM
SECONDARY air fan speed to a preset minimum.
3. After 5 seconds, the blue light will glow steadily and the message "RELOAD" will appear on the operating
display.
4. The combustion chamber door can then be safely opened and the reload can be done.
OBSERVE THE 5 SECOND DELAY
Failure to observe the 5-second delay can cause flashback and smoke when the combustion
chamber door is opened. These flashbacks can cause damage to the building and significant
injury and discomfort to the operator and others in the vicinity of the equipment.
5. When reloading is complete, close the combustion chamber door.
6. Then press the blue push button, which is also the indicator light, or the "RELOAD" message on the operating
display to indicate that the reload is complete.
The OPTIFLAM TM then returns to the previous step, following a pre-set program of a specific period of time to
ensure a quick re-start of the combustion while limiting smoke emission.
