Fire Ready Hood
Cleaning the Hood
To remove built up grease and cooking debris, clean
the unit thoroughly with mild detergent and water. Be
careful when using abrasive cleaning pads as they may
scratch or mar the stainless steel surfaces. The grease
entrapment filter, front discharge grille and grease
tray are dishwasher safe. The carbon filter cannot be
washed and should be replaced periodically as needed.
Inspect the Nozzle Caps
The nozzle caps should be inspected and cleaned. All
five (5) nozzles should have protective caps installed.
If necessary, remove the caps and check for build up
of debris or any signs of clogging of the nozzle orifice.
If clogging is suspected, remove the nozzle with a
7/16-inch wrench, and flush with hot water until it flows
freely through the nozzle.
Replace the nozzle and protective cap.
Replacement caps and nozzle O-rings are available
from Accurex or through your representatives.
Inspect Fusible Link System*
Periodic inspection of the fusible link system ensures
the unit is ready to work in the case of a fire.
1. Place safety pin
in tank valve.
2. Remove tank
from hood.
3. Remove tension
from cable
system by
loosening the turnbuckle.
4. If the fusible links need to be replaced, call 1-800-
355-5354 or contact your representative.
5. Inspect pulleys and cable. Pulleys should rotate freely
and cable should be flexible. Everything should be
free of grease build-up.
6. Tighten the turnbuckle, reapplying tension to the
stainless steel rope, making sure the cable is running
through the pulleys properly and there are no kinks or
knots.
7. Reposition the tank.
8. Remove safety pin from tank valve.
*Each fusible link is date-stamped and must be replaced
if expired or after 12 months of use.
Inspection Procedures
Maintaining the System
WARNING
The protective caps stay on the nozzles at all times. In
the event of a discharge, the caps will blow off.
WARNING
If grease build-up on the cable system is not kept to
a minimum, the cable could become stiff and will not
discharge the suppressant in the event of a fire.
10 Year Maintenance
Hydrostatic testing and new liquid agent, or tank
replacement is recommended at ten-year intervals. The
manufactured date is stamped on the top of the tank.
This should be performed by an authorized technician
or at the manufacturer’s facilities. Material safety data
sheets are available from Accurex.
WARNING
Rubber gloves and safety glasses should be worn
during service or inspection of the tank. If contact
with the chemical agent skin or eyes occurs, flush
immediately with water for 15 minutes. If irritation
persists, contact a physician. If taken internally, do not
induce vomiting. Dilute with water or milk and contact
a physician.
Lighting
Illumination is provided by a 60 watt medium-base
shatterproof incandescent light bulb. To replace, make
sure the light switch is in the “OFF” position and then
gently unscrew the bulb. (Bulb: 60A15/TF)
Removing the Extinguisher Tank
1. Lower the hood to its service position
2. Insert the safety pin in the valve head so that
accidental release of the suppressant does not occur.
3. Unplug the pressure switch wire and move it out of
the way for now.
4. Disconnect the discharge hose from its fitting located
inside the unit closest to the user.
5. Unscrew the two wingnuts holding the bracket for the
tank.
6. Lift the tank out of the hood.
7. To replace the tank, simply reverse these steps.
