UNPACKING AND SETTING UP
MODEL IQ UNCRATING INSTRUCTIONS
A) Check crate(s) for visible damage.
Call Weigh Right if shipping damage is evident.
B) Carefully uncrate machine, Note that one side of the crate may be attached with
wood screws for easy disassembly and re crating if necessary.
C) Remove all separately packaged boxes and open to check contents against packing
list.
D) Carefully remove braces making sure load cell cables are not damaged or stretched.
DO NOT CONNECT AIR OR POWER UNTIL THE MACHINE
HAS BEEN PROPERLY UNPACKED AND INSPECTED!
The machine is shipped on a pallet. Locate the box marked FOOTSWITCH and
remove the straps holding the box to the machine pallet. Open the box and remove the
footswitch assembly and set it aside for now. Lift the machine from the pallet at set it on
the ground.
Remove the wrapping from the outside of the machine. Examine the exterior of the
machine for any visible shipping damage. Remove the remaining packing materials
from the machine and inspect the machine for any damaged, missing or loose
hardware.
IF THERE IS ANY DAMAGE, CONTACT THE DELIVERING CARRIER
IMMEDIATELY AND FILE A CLAIM.

MODEL IQ SAFETY INSTRUCTIONS
1) Never open control panel while power source is connected. Product safety labels
must remain highly visible on the equipment. Establish a regular schedule to check
visibility. Should safety labels require replacement, contact Weigh Right ASC for an
additional supply, free of charge.
2) Disconnect and lock out the power supply before performing any maintenance or
operation adjustments.
3) DO NOT make any alterations to the controls without first contacting the Weigh
Right ASC Engineering Dept. Un-authorized alterations will void the warranty.
Weigh Right ASC will not assume responsibility for damage that may occur due to
unauthorized alterations to the controls.
4) DO NOT dis-assemble to clean when power source is connected.
5) DO NOT put hands or fingers near conveyor when power source is connected.
6) DO NOT remove guards while machine is connected to power supply.
7) DO NOT remove hoppers while machine is connected to power supply.
Control Panel cover must be closed and secured while power source is
connected
INSTALLATION
Machine installation is accomplished in two steps: Positioning of the Machine in Work
Area and Connection of Air and Power. Follow these steps and the machine will be
ready for loading of your product, adjustment and operation.
MACHINE POSITIONING
The machine should be placed so that it can be accessed easily from all four sides. The
top of the machine has a supply hopper for loading of the product; therefore do not
block the top of the machine. The height of the machine, which can be adjusted with
threaded leveling feet, is usually determined by the method by which the bags are filled.
Manual filling will require the machine to be set at a comfortable height for the operator.
Automatic filling processes because of the way they operate usually require the
machine to be set at a pre-engineered height, based on conveyors and other pieces of
equipment.

Page 9
ADJUSTING HEIGHT
Height adjustment of the machine is accomplished by loosening (but not removing) the
four leveling feet on either side of the main machine chassis. Move the machine to the
desired height and tighten the lock nuts. Make sure it is level before tightening the bolts
all the way.
THE MACHINE IS TOP HEAVY! DO NOT LOOSEN THE LEVELING FEET UNTIL
PROVISIONS HAVE BEEN MADE TO SUPPORT THE MACHINE WHEN IT IS OFF
OF THE GROUND. MAKE SURE A 1” MINIMUM OF THREAD IS LEFT IN THE
THREADED FRAME POST.
CONNECTION OF AIR AND POWER
Most IQ 1E(s) machines come with an Air Compressor mounted to the frame. If not, the
main air filter regulator assembly is attached to the right rear corner of the machine and
has a
¼”
NPT port for the plumbing of the air supply. Connection can be made with
either a quick connect nipple or hard plumbed with a hose fitting.
THE AIR SUPPLY TO THE MACHINE IS FITTED WITH A SUPPLY CUTOFF
DEVICE. IN THE EVENT OF AN EMERGENCY SITUATION THIS DEVICE WILL BE
NECESSARY TO DISCONNECT THE MACHINE FROM THE MAIN AIR SUPPLY.
The machine comes equipped with a standard 3-prong male 120-volt line cord. Uncoil
the cord and straighten it out. On the front left corner of the machine, locate the
EMERGENCY STOP switch. Make sure the switch is depressed, which is the off
position. Plug the cord into an acceptable outlet as outlined in set up section on power
requirements.
If a footswitch is supplied, the assembly may be equipped with a 4-pin cable.
Locate the receptacle, align the pins and push the plug into the receptacle.

Page 10
IQ ASSEMBLY INSTRUCTIONS
1. Install (4) leveling feet or casters to machine lower base. Frame should be level
when in final position.
THE MACHINE IS TOP HEAVY! DO NOT LOOSEN THE LEVELING FEET UNTIL
PROVISIONS HAVE BEEN MADE TO SUPPORT THE MACHINE WHEN IT IS OFF
OF THE GROUND. MAKE SURE A 1” MINIMUM OF THREAD IS LEFT IN THE
THREADED FRAME POST.
2. Install weigh buckets onto load cell mounting platform. NOTE: Lower bucket
through rectangular hole in frame, place studs in slot then slip down into “key hole”
notch. (see drawing below)
3. Install machine discharge hopper using hardware provided. (This requires 2 or more
persons.)
4. Re-tighten all electrical terminals and connections after shipping; check for loose
nuts and bolts on machine.
5. Connect air and power; Check scale with 5.00 lb. test weight provided. If scale is
not accurate, follow the calibration procedure as listed in the indicator
instructions. (If scale is oz.; 5 lb. = 80 oz., if scale is grams; 5 lb. = 2268 grams)

General Description
The Weigh Right IQ series is an automatic packaging machine that fills by weight and
dispenses your product into containers or bags.
The product is fed automatically into a weigh bucket by a vibratory feed system. When the
desired preset target weight is attained, a gate or feeder stops the feeding of the product and
the weigh bucket dumps the material into the container when a dump signal is received by
footswitch or conveyor sensor.
The vibratory feed system features multi speed controls for fast bulk feeding and slow dribble
feeding for a fast and accurate fill.
The electronic weigh scale indicates the weight at any time during the filling process through a
digital readout.
The IQ Series features solid state electronic controls for speed, accuracy, and reliability.
Operation
Open hopper flow gates to desired opening for unrestricted product flow.
1. The machine is ready to start feeding product when the supply hopper is full.
2. Rotate (clockwise) the red E-Stop button so it will “pop out”.
3. Press “Start”. Next press the “Hopper Vibr” button to turn on the Supply Hopper Vibrator
(this is optional and not required to run the machine).
4. Press the “Settings” button and enter the desired weight and Fast Rate/Slow Rate fill
speeds. (See the Control section for pictures/explanations of function keys)
5. Adjusting the speeds also changes the filling speed. This range is from 0 -100%. This
unit is equipped with a Fast Rate and Slow Rate sequence. The Fast Rate setting should
always be higher than the Slow Rate setting. This assures the most accurate filling.
6. Note: The machine is factory tested with Typical Settings saved as Job 1. Use
these as an example for “startup” settings and modify them as it suits your
product. Insure the Vibrator Pan has an even flow of product (½” to ¾” deep is
typical) and Fast/Slow Rates at 80/20 (again, these are typical rates). Timers are
then adjusted to obtain a fast and accurate fill of the desired weight.
7. If auto-adjust mode is turned “ON”, run the product through about 50 fill/dump
cycles so the machine may “learn” the correct settings for your product.
8. Before beginning production, press the “zero” key to zero the scale. This also must be
done when the machine is in the “Stop” mode INSURE NO PRODUCT IS IN THE
BUCKET WHEN THIS BUTTON IS PRESSED!
9. Pressing the “Start Scale” starts the filling process.
10. Allow for several dump cycles to complete before adjusting any settings, as product
must fill the trays evenly to achieve proper weights.
