The pressure gauge is directly plumbed to the wet
chemical tank valve assembly and indicates the
pressure status of the nitrogen in the tank. The tank
includes a pressure switch that closes if pressure is in
the "green" or normal operation range.
Resetting Gas Shut-Off Valve
Before the gas supply is turned back on, extinguish any
open flames and turn off all burners and any electrical or
mechanical devices that are capable of igniting gas to
reduce the risk of explosion due to leaking gas. Check
to ensure the power switch is on.
Reset gas shut-off valve by completing the following
steps:
1. On the top of the hood press the white manual reset
button. The gas valve will energize into its normal
operating (open) position.
2. Examine burners for gaseous odor. If gas odor exists,
turn off power switch which will cause the gas valve
to close and shut off gas supply. Clear gas fumes by
opening windows and doors and then correct gas
leak before proceeding.
3. Reset gas valve again and if there is no gaseous
odor, pilot lights may be ignited at this time. Gas
stoves with a pilot light that is always on require
added caution. The pilot light must be relit manually.
Resetting Electrical Relay Shut-Off
1. Check to ensure the power source is on.
2. Press the white manual reset switch on the top of the
hood.
3. Status LED will turn from red to green.
If the system does not reset, one of the following
possibilities may be the problem:
• Tank hose not connected properly
• Tank pressure sensor wire disconnected
• Tank not to adequate pressure
• Electric power is shut off
