RECEIVING AND INSPECTION 

 

Upon receiving the product, check to make sure all items 

including switches 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.  Remove the air intake grille(s) and/or air intake filter(s) 

from the product and set aside. Gently remove all 

packaging materials, hardware,  and all other 

accessories from interior of unit prior to operating. 

Severe unit damage will occur if these items are not 

removed prior to operation. 

2.  Lay unit on its top with directional vanes pointing up and 

remove the Tek Screws from the wall mounting plate, 

just behind the discharge nozzle, and remove the 

mounting plate from the unit.  (FIG. 1)  Measure the 

mounting plate and center it over the opening. The air 

curtain shall be equal to or greater than the width of the 

opening. 

3.  Install the mounting plate(s) above the opening. Multiple 

pre-punched 7/16” mounting holes are provided for your 

convenience. These holes must be utilized to secure 

the product to the wall. All hardware is field provided by 

others. 

4.  Align the tabs on the rear of the unit with the slots 

provided on the wall mounting plate (FIG. 2). The 

bottom flange on the unit must also drop in the bottom 

channel 

of 

the wall mounting plate. Replace the Tek 

Screws to secure the unit in place.

bottom of the wall mounting plate do not align, remove the 

unit and re-install. The holes on the bottom channel of 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.
