Misting Systems

Misting System Overview

What's Included:

• 2 HP Electric Motor
• CF 1520 EH (Pump)
• Unloader Valve + Bypass Kit
• Pressure Gauge
• Check Valve Cap w/ Gauge Port
• Mounting Bolts
  1. Pump to Motor (4x 3/8-16 Bolts)

Tools Required

• Adjustable Wrench and/or Wrench
• Thread Tape (never use thread sealing compound aka Pipe Dope)

INSTALLATION

Assemble Pump and Motor:
Ensure key stock is in place on the motor's shaft. Place the pump's hollow shaft keyway in line with the key stock on the motor and slide the pump onto the shaft. Once the pump is flush with the motor turn it until the pump is level and the bolt holes line up with the holes on the motor. Thread the bolts into place and tighten in a diagonal pattern (see figure 1). Check that pump is filled with oil up to half way line on sight glass (see figure 2) and change the shipping cap for the vented oil cap tightened by hand and not with a wrench (see figure 3).

Attaching Unloader Valve:
Attach unloader valve to pump in three parts, ensure the pressure adjuster pointing upward. 

Begin by removing the brass adjustment knob followed by the tension spring (greased near bottom - avoid touching). Thread the regulator's inlet marked "IN" into the top port on the pump (see figure 4). Once fully the tightened the unloader valve should be pointing 25º to the side leaving enough clearance for the bypass port on the bottom (see figure 5). Now thread the inlet filter into the pump's bottom port and keep note of the position of the two bypass ports. (see figure 4).

With both parts in place, it is time to reinsert the spring, thread the cap back on, and insert the barbed fittings into their respective ports (see figure 5) The barbed fitting with the smaller thread is to be installed in which ever bypass port on the inlet filter is more accessible, remove the plug and thread the fitting in its place.

The final step is putting the clamps on the bypass hose, then pushing each end of the hose onto the barbed fittings and tightening the clamps by turning the knobs clockwise (see figure 6)

Attaching Pressure Gauge:
The first step is to remove the original check valve cap from the top of the pump head (middle of the three is recommended) and double check the check valve below is still in place.

Carefully remove the O-ring from the original check valve cap and transfer it onto the same spot on the new cap with gauge port (see figure 7). Thread the check valve cap with gauge port into the now open thread by hand to begin, once mostly tightened finish with a wrench until fully tight. No thread tape is needed for this step due to the O-ring sealing the check valve cap.

The pressure gauge can now be threaded into place again starting by hand and finishing with a wrench, depending on the amount of thread tape used your gauge position may vary (see figure 8).

Connecting Power:
Connect the power from the motor directly to your power source. Avoid using extension cords as they will lower the performance and life expectancy of the motor. The toggle switch to turn the misting system on is located on the side of the motor (see figure 9). Make sure to reference the above system requirements prior to installation.

Connecting Water: 
Start by connecting the inlet garden hose (not included) to pump's inlet filter with mesh screen (see figure 10). Attach any accessories sold separately including high pressure hose, misting lines, and other compatible parts to the outlet of the unloader valve (see figure 10).
Make sure water is running through the system prior to turning on the Misting System to purge the lines of air. Avoid running the system without water at any time.

Figure 10

Operation:
Now that all is connected to power and water, make sure that water is running through the system, then flip the switch to the "ON" position. You will now have high pressure coming from the pump. The pressure is adjusted with the unloader valve/pressure regulator by turning the adjustment  knob counter clockwise (-) or clockwise (+) as shown on figure 11. DO NOT EXCEED THE PUMP'S RATED PRESSURE.
