MPORTANT!
TO SPEED THE PRIMING PROCESS, YOU MAY REMOVE THE SUPPLY LINE (BOTTOM HOSE) FROM THE
APU UNTIL YOU SEE ENGINE COOLANT START TO FLOW FROM IT. IF YOU USE THIS METHOD TO PRIME THE APU, BE
SURE THAT THE CONTROL CABLE IS FULLY PLUGGED IN OR THAT THE RED SAFETY CAP IS INSTALLED. THIS IS TO
PREVENT ENGINE COOLANT OR OTHER LIQUID FROM ENTERING THE POWER CABLE CONNECTOR. NOT FOLLOWING
THIS IMPORTANT STEP CAN CAUSE THE CONTROL CABLE TO SHORT OUT CAUSING SERIOUS DAMAGE TO THE APU.
