1. on the bolt To be sure the regulator is secure the bolts should have at least two full threads of engagement Startup and Adjustment 1 With proper installation completed and downstream equipment properly adjusted slowly open the upstream and downstream shutoff valve when used while using pressure gauges to monitor pressure To avoid personal injury property damage or equipment damage caused by bursting of pressure containing parts or explosion of accumulated gas never adjust the control spring to produce an outlet pressure higher than the upper limit of the outlet pressure range for that particular spring If the desired outlet pressure is not within the range of the control spring install a spring of the proper range If outlet pressure adjustment is necessary monitor outlet pressure with a gauge during the adjustment procedure The regulator is adjusted by loosening the locknut key 19 if used and turning the adjusting screw or handwheel key 18 clockwise to increase or counterclockwise to decrease the outlet pressure setting Tighten the locknut to maintain the adjustment position Parts List Description Body Drain Valve Flange Screw O Ring Dripwell Filter Element Spring Case Filter Retainer 10 2 Valve Cartridge 11 Valve Plug 122 Valve Spring 132 Valve Retainer 142 O Ring 152 Relief Valve Soft Seat 16 Diaphragm Assembly 17 Spring 18 Adjusting Screw 19 Locknut 20 Upper Spri2. D103076X012 67CFS Series 5 Aclogged spring case vent hole may cause the regulator to function improperly To keep this vent hole from being plugged and to keep the spring case from collecting moisture corrosive chemicals or other foreign material orient the vent to the lowest possible point on the spring case or otherwise protect it Inspect the vent hole regularly to make sure it is not plugged Spring case vent hole orientation may be changed by rotating the spring case with respect to the body The 1 4 inch threaded NPT spring case vent may be remotely vented by installing tubing or piping into the vent 6 For regulator shutdown install upstream block and vent valves and downstream block and vent valves if required or provide some other suitable means of properly venting the regulator inlet and outlet pressures 7 Apply a good grade of pipe compound to the male pipe threads before making connections making sure not to get the pipe compound inside the regulator 8 Install tubing fitting or piping into the 1 4 inch threaded NPT inlet connection on the body key 1 and into the 1 4 inch threaded NPT body outlet connection 9 The second 1 4 inch threaded NPT outlet can be used for a gauge or other use If not used it must be plugged 10 When installing a 67CFS Series regulator in an existing installation it may be necessary to use spacers to adapt the installation If the mounting bolts are too long place a spacer

Installation Sheet Form 5756 January 2009 67CFS Series 67CFS Series Installation Sheet Introduction This installation sheet covers the installation and startup of the 67CFS Series filter regulators If maintenance is required refer to the 67C Series Instruction Manual form 5469 Contact your local Sales Office to receive a copy of the instruction manual Specifications e Maximum Inlet Pressure 250 psig 17 2 bar e Maximum Outlet Pressure 50 psi 3 4 bar over outlet pressure setting e Outlet Pressure Ranges 0 to 35 psig 0 to 2 4 bar 0 to 60 psig 0 to 4 1 bar 0 to 125 psig 0 to 8 6 bar 0 to 150 psig 0 to 10 3 bar e Temperature Capabilities with Nitrile NBR 40 to 180 F 40 to 82 C Installation Personal injury property damage equipment damage or leakage due to escaping gas or bursting of pressure containing parts may result if this regulator is overpressured or is installed where service conditions could exceed the limits given in the specifications or where conditions exceed any ratings of the adjacent piping or piping connections To avoid such injury or damage provide pressure relieving or pressure limiting devices as required by the appropriate code regulation or standard to prevent service conditions from exceeding those limits The internal relief valve in the Type 67CFSR regulator does not provide full overpressure protection www emersonprocess com regulators The inter
4. nal relief valve is designed for minor seat leakage only If maximum inlet pressure to the Type 67CFSR exceeds the maximum pressure ratings of the downstream equipment or exceeds the maximum allowable outlet pressure of the Type 67CFSR additional overpressure protection is required Regulator operation within ratings does not preclude the possibility of physical damage from external sources or debris in the lines Regulators should be inspected for damage periodically and after an overpressure condition Only personnel qualified through training and experience should install operate and maintain a regulator Make sure there is no damage to or foreign material in the regulator and all tubing piping is free of debris Install the regulator so that flow is from the IN to the OUT connection as marked on the regulator body For best drainage orient the drain valve key 2 to the lowest possible point on the dripwell key 5 This orientation may be improved by rotating the dripwell with respect to the body key 1 A regulator may vent some gas to the atmosphere In hazardous or flammable gas service vented gas may accumulate and cause personal injury death or property damage due to fire or explosion Vent a regulator in hazardous gas service to a remote safe location away from air intakes or any hazardous area The vent line or stack opening must be protected against condensation or clogging EMERSON
