WINDGUARD BELT DRIVE (BD) 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:

BD-14 Series

(Environmental Separation up 16’ and Flying Insect

Control 14’), BD-18 Series (Environmental

Separation up 20’ and Flying Insect Control 18’),

BD-22 Series (Environmental Separation up 24’

and Flying Insect Control 22’), BD-26 Series

(Environmental Separation up 28’ and Flying Insect

Control 26’) and BD-30 Series (Environmental

Separation up 32’ and Flying Insect Control 30’).

The units are typically overhead mounted

horizontally above the door opening. They can also

be vertically mounted alongside the opening.

Heated units must be mounted on the inside or the

protected side of the opening. The motors used in

the BD Series range from 5 HP to 30 HP (see

submittal for details).

All the BD Series come standard with an expanded

metal air intake grille(s). The BD Series can be

configured with Flat Bank or V-Bank 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.

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

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.
