Before you open the bleed valve, cover the floor underneath to protect it and hold a cloth underneath the valve to catch any drips.
It can be used on nearly 90 per cent of radiators and replacement bleed valves can be completed within five minutes,
After running emergency checklists in section III of the tech order, the crew determined that the number three strut bleed valve was stuck open, allowing dangerously hot air to enter the manifold.
The gun also has a filler and bleed valve for clean filling or purging trapped air pockets.
A bleed valve that is stuck allows air to be trapped in the system and residents won't get the heat they are requesting at the thermostat.

Axial compressors require dedicated anti-surge systems including five protection arrangements: 1) the anti-surge valves, 2) the hot-gas-bypass valves, 3) the inter-stage bleed valve (IBV), 4) the inlet guide vanes (IGV) system, and 5) the speed variation.
Unlike predecessor APUs, the HGT1700 features variable speed during ground operation which reduces fuel burn by up to 10 percent, a new hydraulic bleed valve for improved reliability, an improved combustor to reduce clogging and improve field durability, and new materials to reduce weight.
