Thermaco VFCA-125 Installation Manual

Trapzilla® Supercapacity Grease Traps

VFCA Vented Flow Control

Installation Instructions

Sometimes space restrictions require the installation of Trapzilla units in basement locations where signicant
head pressure becomes a factor. The Trapzilla® VFCA Vented Flow Control module provides an option for use
with installations where a signicant amount of head pressure is present (greater than 6 ft./1.95 m) or where ap­plicable regulations require vented ow controls. A Vented Flow Control helps reduce problems associated with
high head pressure and helps slow the drainwater ow down. The VFCA kit contains an appropriate tting and
ow control orice.
