Fire Ready Hood

Refer to your submittal for installation dimensions of 
these accessories.

ClockBox (optional)

The ClockBox works by controlling the cooking element 
(gas, electric and dual element ranges) and minimizes 
the likelihood of an unattended cooking fire. The system 
disables the cooking element until the operator unlocks 
the cover and presses the GO button. After two hours 
the cooking element is automatically disabled. 

If this unit was provided with the ClockBox, this device 
should be remotely mounted near the range on nearby 
wall.

Remote ADA Switches (optional)

If the unit is provided with the remote ADA switches, 
these will have to be installed to be in compliance with 
ADA standards for Accessible Design.

Manual Pull Station Installation (optional)

If the unit is provided with the remote ADA switches, 
these will have to be installed to be in compliance with 
ADA standards for Accessible Design.

Parts included in the kit:

Step 1:

  Installing Conduit

Mount the pull box in an appropriate location according 
to local building codes. Keep 
in mind you are supplied with 
25 feet of cable and three (3) 
elbow pulleys. Install 1/2 inch 
conduit (not included) 
between the unit and the 
pull box, using the pulleys as 
needed. Pull cable through 
the conduit, and allow 8 to 
12 inches of slack to be left 
at the hood unit end. Be sure 
to abide by all local building 
codes when installing 
conduit.

Step 2:

  Replace Safety Pin and Key (to prevent 

accidental discharge)

With the unit lowered 
into its service position, 
put the safety pin in 
its slot at the top of 
the extinguisher tank. 
Also replace the safety 
key in its slot in the 
actuator arm. Then 
remove the cable from 
the actuator arm.

Step 3:

  Install Cable and Pin to hood

Thread the cable through the conduit, with the pin 
reaching the unit. Remove the grease filter. In the upper 
right corner, find the two pulleys as illustrated. Hold the 
rear-most pulley in 
place. From the top 
of the unit, replace 
its pin with the one 
on the cable. Push 
the pin through the 
pulley until you hear 
it click in place. Go 
back to the actuator 
arm and rehook 
cable onto the arm.

Step 4:

  Install Cable to Pull Face

With the unit in its lowered 
position, attach the 
cable to the pull face by 
crimping a loop in the 
cable through the hole 
on the back side of the 
handle. Be sure cable 
is securely crimped to 
withstand at least 50 lbs. 
of pull force. Leave no more than 12 inches of slack 
in the line on the pull face end, but maintain 8 to 12 
inches. To make this easier, the handle may be removed 
by loosening the set screw in one of the studs, and 
sliding the red plastic rod out. Attach the pull face to 
the pull box already mounted on the wall, collecting 
any slack into the pull box. Do not allow slack cable to 
collect above the hood.

Installing Ductwork (optional)

Ductwork will need to be provided and installed if the 
unit was provided with an external fan. 

Installation work must be done by qualified person(s) 
in accordance with all applicable codes and standards, 
including fire-rated construction.

To minimize static pressure losses and promote 
adequate airflow, minimize duct run lengths where 
possible.

WARNING

You must allow for 8 to 12 inches of slack in the cable 
to sit at the pull face. Failure to do so will cause the 
unit to discharge the next time the unit is lowered into 
its service position.

CAUTION

Make sure the cable does not become caught on any 
part of the hood or conduit, or the cable will not be 
able to be pulled, and the unit will not discharge.
