Do not apply more than rated power to unit. Damage will occur if large overloads are applied. CAUTION When using any cleaning solvents or solutions, assure that there is adequate ventilation to protect personnel from breathing any irritable or possibly toxic fumes. 6600/Rev/Mar.2021 Page 8 Altronic Research Inc.
Load is correctly connected to the RF source and the transmitter alarm, operate transmitter as desired. Units purchased with fans may be operated after ascertaining that the load is connected to the correct power supply with a disconnect, connect the transmitter interlock 6600/Rev/Mar.2021 Page 9 Altronic Research Inc.
The proper procedure to lock out and mark controls prior to allowing or commencing maintenance on the equipment; The proper procedure to obtain clearance to remove lockouts and out-of-service marks and return the equipment to normal service. 6600/Rev/Mar.2021 Page 10 Altronic Research Inc.
While inspecting RF connector, measure DC resistance of the unit by reading from the center conductor to the outer conductor. Compare this reading to that on the specification sheet at the end of this manual. Reading should be ± 1 ohm. If not, consult factory. 6600/Rev/Mar.2021 Page 11 Altronic Research Inc.
• Test for proper fan operation by jumping the terminals of either thermal switch that is wired in the fan circuit. They have a yellow dot on them. • Place the roof back on the load. 6600/Rev/Mar.2021 Page 12 Altronic Research Inc.
3-10. Preparation for Reshipment. No special measures are required to prepare the Model 6600 Series Coaxial Load for reshipment. Care must be taken to protect the RF connector and to immobilize the swivel flange. Packaging should provide protection against abrasion and impact. 6600/Rev/Mar.2021 Page 13 Altronic Research Inc.
5-2. RF Circuit. The RF Load Resistor does not require any periodic maintenance and the only repairs possible are the replacement of parts in the connector, quickstep or support portions of the resistor assembly or the replacement of resistors. 6600/Rev/Mar.2021 Page 14 Altronic Research Inc.

Removing the resistors without first loosening these screws may cause the resistors to break or crack. The resistors are hard, brittle ceramic material. Avoid impact and excessive force when installing or removing them. Fig. 8 6600/Rev/Mar.2021 Page 16 Altronic Research Inc.

The solution is to remove the resistors and return them to the factory for reprocessing. If the condition is discovered early in the failure, there is every likelihood that all of the resistors can be reused. If the failure is allowed to progress, resistor replacement becomes necessary. 6600/Rev/Mar.2021 Page 27 Altronic Research Inc.
