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 and/or air intake filter. This is accomplished
by removing the screws on the face of each air intake
grille/filter.
4. Thoroughly clean the air intake grille/filter.
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.
CAUTION
The appliance is not to be used by persons (including
children) with reduced physical, sensory, or mental
capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction. Children
are not to play with the appliance.
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. 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.
