WIND STOPPING 14 (WMI) AND WIND STOPPING 16 (WMH)
INDUSTRIAL SERIES
Installation, Operation and Maintenance Manual
Please read and save these instructions. Read carefully before attempting to assemble, install, operate, or maintain
the product described. Protect yourself and others by observing all safety information. Failure to comply with these
instructions could result in personal injury and/or property damage. Retain these instructions for future reference.
OVERVIEW
Mars Air Curtains are
designed to cover door
openings, providing
both temperature
control/environmental
separation and flying
insect control, when
the building’s doors are
opened. Typical
installation heights are:
WMI Series
(Environmental
Separation up to 16’
and Flying Insect Control 14’) and WMH Series
(Environmental Separation up to 20’ and Flying Insect
Control 18’) The units are typically overhead mounted
horizontally above the door opening. They can also be
vertically mounted alongside the opening. The units are
CSA Listed, Canada and US, for either an inside or
outside mount and AMCA Certified. Heated units must
be mounted on the inside or the protected side of the
opening. The motors used in the WMI are 1, 2 and 3 HP
and the WMH utilize the 5 and 7 HP motors.
The WMI/WMH Series come standard with an
expanded metal air intake grille(s). The WMI/WMH
Series can be configured with Flat Bank or V-Bank Filter
Sections, as options.
GENERAL SAFETY
INFORMATION
Use this product only in
the manner intended by
the manufacturer. If you
have any questions,
contact the
manufacturer. Only
qualified personnel
should install this
product. Installing
personnel should have a
clear understanding of
these instructions and
should be aware of general safety precautions.
Improper installation can result in electric shock,
possible injury due to coming in contact with moving
parts, as well as other potential hazards.
WARNING
When servicing the product, motor may be hot enough
to cause pain or injury. Allow motor to cool before
servicing.
WARNING
To reduce the risk of fire, electric shock, or injury to
persons, observe the following.
A. Always disconnect, lock and tag power source before
installing or servicing product.
B. Installation work or electrical wiring must be done by
qualified person(s) in accordance with all applicable
codes and standards, including fire-rated construction.
C. The combustion airflow needed for safe operation of
fuel burning equipment in the area may be affected by
the product’s operation. Follow the heating equipment
manufacturer’s guideline and safety standards, such
as those published by the National Fire Protection
Agency (NFPA), the American Society of Heating,
Refrigeration and Air Conditioning Engineers
(ASHRAE) and local code authorities.
D.When cutting or drilling into a wall or ceiling, be careful
not to damage electrical wiring and other hidden
utilities.

RECEIVING AND INSPECTION
Upon receiving the product, check to make sure all
items are accounted for by referencing the Bill of Lading
to ensure all items were received. Inspect each carton
for shipping damage before accepting delivery. Notify
the freight carrier if any damage is noticed. The carrier
will make notification on the delivery receipt
acknowledging any damage to the product. All damage
should be noted on all copies of the Bill of Lading which
is countersigned by the delivering carrier. A Carrier
Inspection Report should be filled out by the carrier
upon arrival and a report given to the Traffic
Department. If damaged upon arrival, file a claim
immediately with the carrier. Any physical damage to
the unit after acceptance is not the responsibility of
Mars Air Systems.
UNPACKING
Verify that all parts, components and accessories, and
the correct quantities of each have been received. If any
items are missing, report shortages to Mars Air
Systems directly to arrange for obtaining the missing
items. Again, verify quantities received against those on
the Bill of Lading only, as multiple shipments may be
involved.
INSTALLATION
Typical Mounting – Wall or Ceiling Mounted
Horizontally Above the Door Opening
1. Overhead installation is recommended to prevent
the possibility of the unit falling if the wall to which
the unit is mounted is hit by a truck or material
handling device. If however, wall or bracket
mounting is preferred, additional holes may be
drilled in the side panels of the housing.
Note: Bracket/Support mounting is not generally
recommended for Air Curtains equipped with steam
or hot water coils. Overhead installation using
threaded rods with independent suspension of coils
is recommended.
2. Center the unit over the opening. The air curtain
shall be equal to or greater than the width of the
opening.
3. Four pre-punched 1/2” mounting holes on the top of
the unit are provided for your convenience. These
holes must be utilized to secure the product
overhead. All hardware is field provided by others.
4. Mount the product such that the discharge is 1”
above the opening and all obstacles. (FIG. 1)
Note: If the product is installed higher than the
recommended 1” above the opening, then it must be
moved 3/8” away from the wall for every 1” that it is
moved up. Any void between the wall and the product
must be sealed, by others, to optimize performance.
FIG. 1
5. Use four (4) threaded rods for overhead installation
or four (4) threaded bolts for wall installation. All
hardware is field provided by others. (FIG. 1)
6. If applicable, for tandem installation or products
mounted side by side, allow no more than 6”
between the two products. For overhead installation
using threaded rods, the products may require a
beam, by others, to span the full distance of the
mounting length. (Reference Accessory
Installation Supplement)
7. All wires must be connected to the external junction
box(s) of the unit.
8. The unit must be wired per NEC and local codes.
Electrical Field Wiring
The unit and any optional accessories must be wired
with the proper voltage to the junction box per the wiring
diagram. (FIG. 2, unheated products only)
WARNING
Precaution should be taken in explosive atmospheres.
