• T60ANNN – T60E IDLE&PRIMER- no vaccuum lockoff  – #1333
• T60-AVP-N VAC.LOCK/IDLE PRIMER – has vaccuum lockoff – #1331

Note:There are 3 features available on the T60, Idle Feature, Vacuum Lock, & Manual Primer
The Primer & Idle are easy to determine, and for the Vacuum Lock if you look on the front cover there is a port that says VAC, you will either have a pipe plug in that port meaning there is no built in vacuum lock, or there will be a fitting with a small vacuum hose going to it meaning that you do have a built in vacuum lock, you will use that fitting & vacuum hose on your new T60

The T60 is a two stage regulator/vaporizer for LPG applications up to 60hp (45Kw). Various models feature
built-in vacuum lockoffs, idle adjustment, primers, various heating methods, and several mounting options.
Newly designed models (scheduled for spring 2010 production) include an improved primary and secondary
lever and seat design, and a standard freeze plug and idle screw. The idle screw has improved sensitivity and
stability and is relocated to the cover. An idle screw cap and tamper resistant screws satisfy regulatory tamper
resistance requirements. Optional dual mounting tabs are available and all mounting features and ports will
remain the same.
