The charging process can be speeded up by applying swabs dipped in warm water to the refrigerant cylinder. Never heat cylinders with a blowtorch or immerse them in boiling or very hot water. A rapid charger is available. This device, fitted between the hose and the cylinder, acts as a restrictor or limit valve, maintaining a higher constant pressure in the cylinder and preventing early frosting. The vapour passing through the device is less superheated when it reaches the compressor, so less time is taken to charge the system | SPECIAL STUDY INJURIES AND DEATHS ASSOCIATED WITH CHILDREN S PLAYGROUND EQUIPMENT April 2001 Deborah K.
