Once the hood has been installed, it may be necessary or desired to test the unit with a test tank. This is a tank lled only
with pressurized nitrogen (Need to order separately).
1. Following the “Removing the Extinguisher Tank” instructions in the service manual, remove the extinguisher tank and
replace it with a test tank.
2. The unit can be actuated one of two ways:
A. Cut Test Links: Replace the actuator arm’s safety key. Loosen the turnbuckle in the fusible link cable assembly (underside
of hood). Replace one of the fusible links with a test link. Re-tighten the turnbuckle to the proper tension. Remove the safety
key and raise the unit to its operational position. To test, cut the test link with wire cutters or similar.
B. Manual pull kit (if installed): Raise the unit to its operational position after the test tank has been installed. Remove the
plastic break rod from the pull face with an allen wrench (refer to manual pull station appendix for more detailed infomation
on this). Pull the handle to actuate the unit. Refer to the manual pull kit appendix on how to return the pull station to an
operational state.
