A. Removal of Control Valve Bank
1. Before removing, mark each valve and all the hoses that connect to the valves in order to simplify
remounting procedures. The marking must be one which will provide a more permanent mark, so much so
that the mark will not only positively identify the valve, but will ensure that the mark will not be washed off
or rubbed off during disassembly and repair functions.
2. Having marked the hoses, disconnect them. Remove all fittings from the valves. Remove the attaching
hardware and remove the valve bank as an assembly.
DO NOT DISASSEMBLE VALVE IN THE FIELD.
