Saros Performance Verification Test - CAIRE SAROS 4000 Service Manual

NOTE: The entire verification procedure is recommended to be completed after repairs to verify overall functionality of the unit.
Verify functionality of the SAROS using the following procedures. The performance verification test shall be performed upon
initial receipt of the SAROS, any time a problem is suspected, and at regular 6 month intervals. It may be performed at more fre-
quent intervals if required by the equipment provider. It is suggested that these steps be performed in the order listed for efficiency
and accuracy.
2.3.1 General Operation Test
1) Install the SAROS battery.
2) Use an external (AC or DC) power cord to connect the SAROS to external power. Verify the power cord connects securely to the
receptacle on the SAROS.
NOTE: The battery is not fully charged upon initial receipt of the SAROS. If testing a new unit, this will begin the battery charging
process. Reference steps 7-8 to verify proper battery charging.
3) Press and hold the "ON/OFF" button for 3 seconds to power on the SAROS.
NOTE: Before powering on, ensure the SAROS is in the well-ventilated area and that the air inlet
and exhaust vent are not obstructed.
4) Verify the audible alarm sounds upon start-up and the screen defaults to display a flow setting of C3.
5) Allow the unit to run for a minimum of 5 minutes to reach its performance specifications. After the
warm-up period, verify that only the green light remains illuminated and there are no audible alarms.
6) Press the utility button once and verify that there are no active alarms. The display screen will read "AC
= NONE" if no alarms are active.
7) Verify that the battery icon is visible on the right side of the screen.
8) Verify that the battery is charging. The battery icon bars will move in a waterfall fashion while charging.
If the battery icon is not moving, verify if the battery is already fully charged. A fully charged battery will
have a completely dark icon with all bars filled.
9) Verify the functionality of the increase and decrease flow buttons. Starting at flow setting C3, press the
decrease flow button and verify the screen reads C2. Press the increase flow button and verify the screen
changes back to C3.
NOTE: It is normal for the motor to speed up or slow down with each flow adjustment.
