   CLEAN AIR SYSTEMS

COMPRESSED AIR INSTALLATION:

The compressed air inlet for the Roto-Pulse cleaning 
system is at the top of the surge tank located on the side of 
the unit (Figure 15).  A minimum of a 3/4 inch diameter 
line and 

clean, dry compressed air at a pressure of 80 psi 

to 90 psi is required

 for proper operation of the Roto-pulse 

cleaning system.  For models FRP8-3 and FRP8-4 two 3/4 
inch diameter lines from a minimum 1 inch diameter header 
line are required.  A unit specifi c combination regulator/
fi lter dryer is highly recommended for proper operation.

ELECTRICAL INSTALATION:
       Caution: Installation can cause 
exposure to live components.  Disconnect 
electrical power before proceeding with 
installation.  Proper lock out/tag out 
procedures should be used.

PULSE CONTROLS ONLY ELECTRICAL BOX
1.  Open the electrical box cover located on the side of the 

unit.  Make connections from your 120V supply power 
to terminal L, N and G (Figure 16).

2.  When supply power has been terminated, reconnect 

the power.  Momentarily turn the motor blower on and 
adjust pressure switch via set screw until contact is 
made.  Use an ohm meter to measure continuity across 
the pressure switch.

FULL CONTROL ELECTRICAL BOX
1.  Determine the location for mounting the electrical box 

(on the unit or remotely).  If mounting is on the unit 
mount near the pulse jumper box in order to minimize 
electrical runs if feasible.

2.  Mount the electrical box.
3.  Open the electrical box cover located on the side of 

the unit.  Make connections from your 208V, 230V, or 
460V supply power to power distribution terminal L1, 
L2, and L3 (Figure 17).  Wire size should be rated for 
FLA of your application.
