Introduction
This manual details the proper steps for installing the Eriez
E-Z Tec®Model IV and V Metal Detectors.
Careful attention to these Installation Requirements will
assure the most efficient and dependable performance of
this equipment.
If there are any questions or comments about the manual,
please call the factory at 814/835-6000 for E-Z Tec®Metal
Detector assistance.

CAUTION - ELECTROMAGNETIC FIELDS
• Metal Detectors emit electromagnetic fields. Contact the American
Conference of Governmental Industrial Hygenists, Cincinnati,Ohio,
U.S.A., (www.acgih.org) for additional information.
• If you use a medical implant or similar device, you must never
approach the equipment because your device may malfunction in
the electromagnetic field, with consequences up to and including
death.
Contact Eriez if you have a question regarding these precautions.

Handling Instructions
PLEASE LEAVE THESE INSTRUCTIONS ATTACHED
TOTHE EQUIPMENT UNTIL INSTALLATION IS COMPLETE
1. DO NOT LIFT THE METAL DETECTOR BY
INSERTINGANYTHINGINTOORTHROUGH
THE APERTURE. The inner surface of the
aperture is delicate and is surrounded by a
precisely tuned electronic circuit that must not
be disturbed. Any damage to this surface or
anyaperturedistortioncausedbyhandlingwill
invalidate Eriez’ warranty.
2. HANDLE THE SHIPPING PALLET NOT THE
DETECTOR. Keep the metal detector on its
shipping pallet as long as possible.
3. When you must remove the detector from the
shipping pallet, LIFT ONLY ON DETECTOR
HOUSING SERVICES THAT INCLUDE
SUPPORTING“FEET”ORTAPPEDLUGS,as
supplied by Eriez.
4. LIFT BY HAND IF POSSIBLE, or by using
a crane and soft nylon slings running under
the entire detector housing - NOT
THROUGH THE APERTURE. Block the
slings to prevent rubbing on the remainder
of the detector housing.
5. The metal detector is heavy. Use care
when handling to avoid injury to personnel
or damage to property.
6. Never weld any attachment to the detector
housing. Do not attempt to drill and/or tap
the metal detector housing for lifting or
mounting attachments.
7. Neverliftwitha craneorforklift underthe“chin”
of the control housing that juts out from the
metal detector housing. Make certain that
lifting straps and other handling equipment do
not contact the control housing.
8. If handling with eye-bolts threaded into pre-
tapped holes supplied by Eriez:
a. Makesurethateye-boltsarestrong enough
for the loads that will be applied
b. Never apply loads perpendicular to the
shank of the eye-bolts; they will break.
