NOTE: Some of the information in this manual may not apply if a special unit was ordered. If additional drawings
for a special unit are necessary, they have been inserted. Contact MAI if further information
is required.
RECEIVING THE HEAT EXCHANGER
Inspect the Heat Exchanger. Check for concealed damage that may have occurred during shipment. Look for dents,
scratches, loose assemblies, etc. Damage evident upon receipt should be noted on the freight bill. Damage should be
brought to the attention of the delivering carrier -- NOT to MAI- within 15 days of
delivery. Save the carton and packing material and request an inspection. Then file a claim with the delivering
carrier.
MAI cannot accept responsibility for freight damages; however, we will assist you in any
way possible.
TESTING THE HEAT EXCHANGER
TEST FOR FUNCTIONALITY BEFORE MOUNTING THE HEAT EXCHANGER TO THE ENCLOSURE.
Refer to nameplate for proper electrical current requirements, and then connect power cord to a properly grounded
power supply. Minimum circuit ampacity should be at least 125% of the amperage shown in the design data section
for the appropriate model. No other equipment should be connected to this circuit to prevent overloading.
Operate the heat exchanger for several minutes. No excessive noise or vibration should be evident during this run
period. Ambient air mover may not be energized at temperatures low enough to not require cooling. On DC powered
units air movers may not always be running at full speed.
