Removing the High Flow Turbo Meter Head Assembly
A typical installation would be equipped with drain and piping valves To inspect or replace components of the High Flow
Turbo Head Assembly, close the upstream and downstream valves However, if the installation does not have a drain valve,
proceed as follows to relieve pressure See Figure 8 on page 12
UPSTREAM AND DOWNSTREAM VALVES MUST BE CLOSED BEFORE ATTEMPTING TO REMOVE METER HEAD FROM
HOUSING. FAILURE TO DO SO CAN LEAD TO THE HEAD BEING "EJECTED" FROM HOUSING, CAUSING PERSONAL INJURY
AND/OR PROPERTY DAMAGE!
1 Loosen each of the High Flow Turbo Head Assembly bolts about 1-1/2 turns Do not completely remove the bolts
2 If the O-ring between the High Flow Turbo Head Assembly and the housing is secure and not leaking, pry the
Measuring Element Assembly loose by inserting a screwdriver blade where the head and housing join together
BE SURE THAT ANY WATER COMING OUT OF THE METER HEAD DOES NOT SPRAY ONTO ELECTRICAL EQUIPMENT AND
CREATE A SHOCK HAZARD.
3 Allow the meter to drain and relieve internal pressure
4 When pressure is relieved, remove the head bolts Lift the Turbo measuring element assembly from the housing
