Avtron Resistive Load Bank - Part Number LPV600 994210
3-2
AIRFLOW CONSIDERATIONS
Even with an ample supply of cooling air, the Load Bank may overheat, if it is not properly
installed. There are two types of airflow problems that should be avoided:
1. RECIRCULATING AIRFLOW - If the hot, exhausted air is permitted to recirculate through
the Load Bank, it will reach such a high temperature and low density that it will no longer
cool the resistance elements. Maximum allowable intake air temperature is 110F. A Load
Bank should not be installed so close to any surface which may reflect the exhausted air back
to the air intake. When two or more Load Banks are being used, care must be taken in
positioning the Load Banks so that the exhausted air of one unit does not feed the air intake
of another.
2. RESTRICTION OF COOLING AIR - Any obstruction located within four (4) feet of the
inlet or twelve (12) feet of exhaust screens will restrict the Load Bank's airflow. Airflow is
also restricted when two or more Load Banks have air inlets positioned close to each other.
This competition for cooling air causes a low pressure area, restricting adequate airflow to
either unit.

W A R N I N G
It is vitally important to install the Load Bank properly. Installation
errors may result in a catastrophic failure. The Airflow switch, a
protective device in the Load Bank, will guard against some of these
problems. If protective circuitry prevents application of the load,
determine the source of the problem. DO NOT DISABLE the
AIRFLOW SWITCH. This will cause a safety hazard and will void
our warranty. The following installation instructions are critical to
the safe operation of the Load Bank. (Refer to Section I, SAFETY
CONSIDERATIONS, of this manual.)
*************************************************************
3. The heated exhaust air stream can damage any temperature sensitive items if they are
positioned within 30 ft. of exhaust air.
4. Load Banks mounted into a channel, trough, hollow, well, or pit, or exhausting into a full
wall or corner, require special considerations even if above conditions are met. In these
cases, provide a detailed sketch of site layout for Avtron to inspect and comment.
