Cool it with PM.Staying cool is the key to preventing thermal receiving unit (TRU TRU True TRU Thompson Rivers University (Canada) TRU Toys R Us TRU Transuranic TRU Teenage Research Unlimited TRU The Root Underground (gaming clan) TRU Transuranium TRU Transformer Rectifier Unit ) failure on your MI-series tank.

Help your TRU keep its cool with these PM tips: Crewmen * Keep the TRU turned off during daylight hours and at night when it's not in use. Unnecessary use increases the chance of a failure. * Pay attention to how long it takes the TRU to cool down. If it consistently takes longer than 15 minutes, the cooler assembly is probably low on helium. Report it. Mechanics * Keep your hands off the cooler assembly when removing or installing the TRU. Use it as a handhold hand·hold n. 1. A grip of or by the hand. 2. Something that one can hold onto for support. Noun 1. handhold - an appendage to hold onto appendage - a part that is joined to something larger and the seals will pull loose.
