Cleaning
Prevent grease buildup on the timer by wiping it down with a clean, damp cloth every day. Avoid
using abrasive or chemically reactive cleaners, which could damage the control panel.
Non-120-volt operation
This device is shipped with a three-pronged, 120-volt-compatible outlet plug (NEMA 5-15P). If
your local power supply is not compatible with this type of outlet plug, consult an authorized
electrician for modification of the outlet plug.

A logical location in which to install the timer is on the surface of a fume hood above cooking
equipment. You will need the following hand tools to install the timer:
Electric drill

1. Two hanging brackets, 2. two adjustable knobs, 3. two large washers, 4. four machine
screws, 5. four nuts.
To install:
With holed flanges facing either inward or outward, slide a hanging bracket over the
adjustable knob’s threads and then slide on the large washers.
Fasten the knob to one side of the timer and repeat for the opposite side.
Use the timer assembly to mark the four mounting holes.
Drill the four mounting holes.
Place the timer assembly over the 4 mounting holes and press the four supplied screws
through the mounting brackets into the mounting surface (the hanging brackets can be
removed from the timer to reduce the weight during mounting).

Operating Instructions
Powering up
Make sure that the timer is plugged in and flip the On/Off switch on the front of the unit to “On.”
The left display, designated as active with the triangle symbol, will read READY. Press the Right
Arrow to switch to the right display (16-Channel timers only).
Running single menu item functions
In Single Page Mode, the display reads READY. Stored menu items correspond to the buttons
on the active display. The names of menu items are displayed along the top and bottom of the
4
center display, above or below their corresponding buttons. Buttons that do not have
corresponding menu items will show blank spaces.
Pressing the button that corresponds to the desired menu item will start the first item
function. The center display area briefly shows the menu item name and STARTED. The
menu item name then flashes to indicate that the cycle is active and the time for the first
function counts down. The menu item name alternates with an asterisk (*).
Each menu item can have up to 10 functions, each of which is displayed as the time counts
down on the function. The seven default settings are:
CHECK
REMOV (remove)
SHAKE
HOLD
STIR
TURN
SEAR
Cancelling function: Hold down the menu item’s corresponding button until the display reads
ITEM_CANCELLED.
Pre-Alarms: With this feature, five short beeps sound when five seconds remain in a function,
informing the operator.
View remaining time, last function: Press the corresponding button on an item in operation
to view the current function name and time. Press the item button again and the last function
will display for 5 seconds and revert to the next function.
Alarms: The timer will beep when a function is complete and operator action may or may not be
necessary. The display shows the expiring function until the alarm stops. There are three
different alarm settings:
Auto – The timer beeps for a few seconds and stops.
Repeat – The timer beeps; press the corresponding menu item button to stop the alarm within
five seconds or the alarm will change to a higher pitch and faster rate until the timing cycle is
restarted by the press of a button. HOLD cannot be set to repeat.

Manual – The timer beeps; press the corresponding menu item button to stop the alarm within
five seconds or the alarm will change to a higher tone and faster beep rate until cancelled. After

display.
Running items from additional stored menu pages
Up to eight pages of menu items can be stored in the timer.
