An accessory liquid propane kit is available for 48TJD/E016, 48TJD020,<br />
48TJD024, and 48TJD028 units. Refer to accessory literature for<br />
more details.<br />
***The 48TJ028 unit requires 2-in. industrial-grade filters capable of<br />
handling face velocities of up to 625 ft/min (such as American Air<br />
Filter no. 5700 or equivalent).<br />
NOTE: The 48TJ004-014 units have a loss-of-charge/low-pressure switch<br />
(accessory or option) located in the liquid line. The 48TJ016-028 units<br />
have a low-pressure switch (standard) located on the suction side.
