! CAUTION: The Temperature Controller’s “Alarm” functions are NOT used in the chamber’s safety system and are NOT connected. TestEquity does NOT recommend using the Temperature Controller’s alarm function as the main protection device. The independent EZ-Zone Limit Controller functions as the main protection device. - Page 6 You are responsible for providing thermal protection devices to your test sample. ! CAUTION: To prevent damage to your test sample and the chamber’s compressor, do not exceed the live load rating of the chamber. Page 1-2 TestEquity 115R Temperature Chamber...

Not all features or functions are applicable. Only the capabilities of a model PM6L1AJ-AAAABAA are applicable. ! CAUTION: The EZ-Zone Limit Controller has been properly configured by TestEquity to match the chamber’s system requirements. Improper modifications to these setup values can result in unreliable and unsafe operation. Do not attempt to modify the setup values, unless you thoroughly understand what you are doing. -

50 Hz rating of 100 V nominal (95 V min. to 110 V max.). We do make a special export version for this purpose, model 115R-EX. It has 230 V, 50 Hz compressors and an internal step-down transformer for the heater and control circuitry. - Page 18 I haven’t used the chamber for a while. Is there anything I should do to prepare it for operation? Perform ALL the steps in the Preventive Maintenance Schedule before placing the chamber back into service. This will ensure that nothing has been damaged and that a leak has not developed. Page 6-2 TestEquity 115R Temperature Chamber...

NOTE: You may need to clean the condenser more frequently if the chamber is in a dusty environment. You may be able to clean the condenser less frequently if the chamber is in a very clean environment. Page 8-2 TestEquity 115R Temperature Chamber... -
Page 25: How To Inspect The Electrical & Refrigeration Machinery Compartments
TestEquity recommends verifying the calibration before attempting to actually perform a calibration. The state-of-the-art instrumentation used in TestEquity chambers is of the highest quality and seldom goes out of calibration. If you try to calibrate the instrumentation before determining that calibration is necessary, you may make it worse if done incorrectly. -

These tests assume that the Temperature Controller’s setup and tuning values have not been changed from the values as shipped from TestEquity. Also, the Limit Controller high limit must be set to over +85°C (+88°C would be fine), and the low limit set to –74°C. The ambient temperature must be approximately 23°C for the cool down times to be valid. -
Page 27: Theory Of Operation
The compressor takes the low pressure vapor and compresses it, increasing both the pressure and the temperature. The hot, high pressure vapor is forced out the compressor discharge valve and into the desuperheater. The finned coil TestEquity 115R Temperature Chamber Page 8-5... - Page 28 The low-stage compressor turns on 30 seconds after the high-stage turns on through Timing Module (TM1). This reduces the system’s starting current, while allowing the cascade condenser to get cool before the low-stage turns on. Page 8-6 TestEquity 115R Temperature Chamber...
