b. A clean dry source compressed air rated at 80-100psig @ 10cfm will need to be installed to the inlet of the
manual 3-way air control valve located on the top of the air/oil hydraulic reservoir. Hard piping the
compressed air line is recommended. Use the largest hose or pipe permitted. A small air line will cause an
extended time frame to pressurize the reservoir and time to raise the Mixer.

c. After filling the air/oil hydraulic reservoir and installing the compressed air line, the hydraulic cylinder will
need to be bled of all air by using the air bleed valve located on the upper cylinder wall, near the upper flange
of the cylinder. Apply compressed air to the cylinder by moving the 3-way control valve to the "pressure"
location. When the reservoir is pressurized, depress the hand valve to allow oil to flow into the cylinder.
Open the bleed valve on the top/side of the cylinder and allow the air to bleed out of the cylinder. All of the
air is bled when the oil comes out of the bleed valve in a clear stream without any air bubbles.

Shaft Seals.

a. As standard, the CDA Agitator Shafts are sealed with a Dry Running Double Flexi-Lip Seal. This Seal is
installed from below (underside of) the Vacuum Cover and requires no adjustment, lubrication or
maintenance. Keep the area around the seal clean and free of dirt/debris to protect the seal and provide a long
life for the seal.

b. As an option, the Agitator Shafts may be sealed at the Vacuum Cover with single mechanical seals. These
mechanical seals and the lower shaft bearings are lubricated with oil.

NEVER ALLOW THESE SEALS AND

BEARINGS TO RUN DRY.

Check the oil level at the oil gauge sight on the side of the bearing housing/tower and

add oil as necessary to keep this sight gauge full at the center line. Use any good quality multigrade automotive oil
suitable for 250 to 300 degrees F. The upper shaft bearing is lubricated via grease and a grease fitting located
adjacent to the upper bearing.

6. Shaft Bearings.

For all CDA mixers with Flexi-Lip Shaft Seals installed or “Atmospheric” designs, the upper and

lower shaft bearings are lubricated via grease and the grease fitting located adjacent to the upper and lower bearings.
A breather is located between the bearings to allow heated air to escape.

7. Motor Bearings.

These bearings have been greased at the factory and should be greased every 500 hours

minimum with a premium high temperature synthetic bearing grease if a grease fitting is installed on the motor. Smaller
HP motors will not have grease fittings and will have greased for life sealed bearings.

F. MIX CAN.

1. Before starting the mixing operation the mix can must be securely attached to the mixer can lock and
leveled to the vacuum cover/hood.

2. The can is positioned and held in place by two locking pins located at the back of the can.

G. THERMOCOUPLE, THERMOWELL.

The Thermocouple is located in the Vacuum Cover and/or in the sidewall of the Mix Can. Connect the
Thermocouple to the Control Panel as shown in the electrical wiring schematics. The typical Thermocouple is
a type "J". The Thermocouple wire must be matched with the type of Thermocouple.

H. GROUNDING CABLES.

Grounding cables are recommended to be installed between the Mixer and an earthen ground to dissipate any
potential static charges. Additional grounding cables should be attached from the Mixer to the Mix Can and
other associated/attached equipment.
