MAINTENANCE
Routine maintenance is required to keep this product
operating at its peak performance and efficiency. Over
time, the housing, air intake grille, air intake filter, blower
wheels and motor(s) will accumulate a build up of dust,
debris and other residue. It is imperative to keep these
components clean. Failure to do so will not only lower
operational efficiency and performance, but also reduce
the useful life of the product. The time between cleanings
depends on the application, location, and daily hours of
use. On average, under normal use conditions, the
product should require a thorough cleaning once every
six (6) months.
To clean the product, perform the following:
1. Verify the product has been disconnected from the
power source.
2. Use a damp cloth and either a warm mild soapy water
solution or bio-degradable degreaser, to wipe down the
exterior components of the housing.
3. To access the interior of the product, remove the air
intake grille(s) and/or air intake filter(s). This is
accomplished by removing the screws on the face of the
air intake grille(s)/filter(s) and releasing the grille by
pulling on the spring hinge.
4. Thoroughly clean the air intake grille(s) and clean or
replace the intake filter(s).
5. Thoroughly wipe down the motor, blower wheels and
blower wheel housings. Be careful not to spray the
motor with a water hose.
6. The motor(s) require no additional lubrication. They are
permanently lubricated and feature double sealed ball
bearings.
7. To re-install the product, reverse the procedures above.
8. Reconnect the power source to the product.
9. If you have any questions regarding the maintenance of
the product, contact the manufacturer.
SPECIAL APPLICATIONS
Outdoor Installation
For outdoor unit special consideration may be required
for enclosure, motor, wheel, and other components to
minimize damage caused by exposure to the outdoor
elements. Contact factory for special construction and
costing.
Freezer and Cooler Installation
Air curtain must be mounted on the warm side for optimal
performance. Variable Frequency Drive (VFD) is strongly
recommended to control the air curtain air flow velocity at
the floor level.
High humid areas may require de-humidifier or additional
defrost cycle to minimize condensation and freezing for
freezer applications. We recommend the air curtain unit
to not replace doors but work in conjunction with door
opening sequence cycle.
Contact factory for details.
DISCLAIMER
Mars reserves the right to change specifications and
product design without notice. Such revisions do not
entitle the buyer to corresponding changes,
improvements, additions, or replacements for previously
purchased equipment.
L. VERY IMPORTANT Using a clamp meter, measure
the amperage to each motor and ensure that they do
not exceed the amperage listed on the product label.
M. If applicable, adjust the air intake grille(s) such that the
output air stream reaches the floor. For temperature
control and environmental separation applications, the
air stream should reach the floor with sufficient
strength to create an air seal around the door opening
without creating turbulent mixing of the inside and
outside air. If applicable, adjust the air intake grille(s)
such that the output air stream reaches the floor. For
flying insect control applications, the air stream should
reach the floor with maximum strength. If after proper
installation and adjustment, the product appears to be
producing too little or too much air for the application,
contact the manufacturer.
WARNING
To reduce the risk of fire, electrical shock, or injury to
persons, observe the following:
A. Maintenance is to be performed only by qualified
personnel who are familiar with local codes and
regulations and are experienced with this type of
product.
B. Before servicing or cleaning the product switch power
off at service panel and lock service panel to prevent
power from being switched “ON” accidentally.

NOTE
Before proceeding, refer to the units specific IOM Manual for safety, installation and start information. Verify
proper voltage to the product per local and NEC codes. Ensure proper rotation for units with three phase
motors.
Unobstructed clearance space of 18”-24” must be
provided at the top of air curtain for performance and
service for all heated air curtain.

Steam and Hot Water Coil Heated Products
Steam/Hot Water Coil (coil) heated products must
be mounted on the inside of the building. The coil(s) for
Low Profile, Standard, High Velocity, Extra Power and
Phantom units are shipped internally mounted to the unit.
Wind Stopping and WindGuard units are shipped with
coil(s) factory mounted.
Once the coil has been secured to the cabinet, access to
the motor and fan is through the removable access
panels located on the top of the cabinet for Standard,
High Velocity, Extra Power and Phantom units.
Note: Low Profile and Wind Stopping units require the
removal of the coil to access the motor and/or fans.
All piping should be done by a licensed pipe fitter and in
accordance with local codes and regulations. Connect
the supply and return fittings as required. All traps and
valves are sized and field-installed by others. For
Standard, High Velocity and Extra Power units, front
intake screen must be removed to access vent plugs.
Standard coil configuration is right hand supply and left-
hand return. (FIGS. 3 & 4) Optional temperature controls,
if ordered, are to be field installed by others.

WARRANTY
Mars’ warranty coverage, period, extent, and
limitations apply to the product only. It does not apply
to labor. Mars warrants that the Mars product 1) is
free from defects in materials and workmanship, and
2) conforms to Mars’ published specifications. The
warranty period for Mars products (except for heated
models, custom models, or WMI, WMH and BD
models) is a five (5) year period commencing on the
date of shipment. The warranty for heated models is
an eighteen (18) month period, the warranty for
custom models and for accessories is a twelve (12)
month period, and the warranty for WMI, WMH, and
BD models is a twelve (12) month period. The date
on the customer’s invoice is the date of shipment
unless Mars or your reseller informs you and Mars
otherwise. Mars will provide free replacement of any
part that fails as a result of a defect in material or
manufacturer’s workmanship. Changes in
operational specification parameters that differ from
those provided on the original purchase order are not
covered. Mars products are inspected and tested
before packaging and are shipped in working
condition. The warranty for Mars products only
covers free-of-charge replacement of failed parts.
The warranty does not cover labor and transportation
expenses that may be required to deliver and to
install replacement parts. Because in many

economic consequential damages (including lost
profits and savings), regardless of whether Mars, its
suppliers, or its resellers were informed of the
possibility of damages. The warranty does not cover
repair or exchange of Mars products resulting from
misuse, accidental damage, modification, unsuitable
physical or operating environment, improper
maintenance or installation by customer, or failure
caused by a product for which Mars is not
responsible. The warranty does not cover damages
caused by mishandling during transportation. The
warranty is voided by removal or alteration of Mars
product or parts identification labels, and by improper
installation of product and resulting non-compliance
with federal, state, and local codes and regulations.
Additionally, Mars reserves the right to void the
warranty for non-payment of invoice.
