The T-4000-605 (Beige) and T-4000-630 (White)  Universal Pneumatic Room Instrument Conversion  Kits are designed for remodeling existing room  instrument installations; both Johnson Controls and  non-Johnson Controls. These kits can be applied to  both exposed and concealed tubing existing  instrument installations. The procedures for  application of these kits are described under  appropriate sections titled: Exposed Tubing  Installations, Non-Johnson Controls Installations and  Johnson Controls T-400 Series and H-100 Series  Installations.  All of the parts required and the instructions for  converting 1, 2 and 3 tube existing instruments are  contained in these kits (see Table 1); leftover or  unused parts should be discarded. New thermostats,  humidistats, temperature or humidity transmitters,  covers and wire or cast guard kits (if required) must  be ordered separately. Tables 2a and 2b list all of the  known conversions. In all cases, if the existing  installation is surface mounted or has exposed tubing,  use the conversion procedure described in the  “Exposed Tubing Installations” section.
