WARNING

Installation

3A6980A 5

Installation

Grounding

Pump: Always ground the entire fluid system by making

sure the fluid has an electrical path to a true earth

ground. Ground screws are provided on all pumps. The

ground screws are located on the bottom cover of the air

motor, under the shield on the 6:1 piston pump.

Air and fluid hoses: Use only electrically conductive

hoses with a maximum of 500 ft (150 m) combined hose

length to ensure grounding continuity. Check electrical

resistance of hoses. If the total resistance to ground

exceeds 25 megohms, replace the hose immediately.

Air compressors: Follow manufacturer’s

recommendations.

Dispense valve: Ground through connection to a

properly grounded fluid hose and pump.

Material supply container: Follow local code.

Container(s) that receive material: Follow local code.

Solvent pails used when flushing: Follow local code.

Use only conductive metal pails, placed on a grounded

surface. Do not place the pail on a nonconductive

surface, such as paper or cardboard, which interrupts

grounding continuity.

To maintain grounding continuity when flushing or

relieving pressure: Hold the metal part of the dispense

valve firmly to the side of a grounded metal pail, then

trigger the valve.

Location

Position the ram so the air controls are easily

accessible. Ensure that there is sufficient overhead

clearance when the ram is fully raised. See Repair,

page 14.

Position the ram in an area with adequate access for

servicing and cleaning the equipment and adjacent

areas to maintain the required level of hygiene. Locate

equipment away from sources of air currents, dust, or

liquids derived from leakage, condensation, or aerosols.

Using the holes in the ram base as a guide, drill holes

for 1/2 in. (13 mm) anchors.

Check that the ram base is level in all directions. If

necessary, level the base using metal shims. Secure the

base to the floor using 1/2 in. (13 mm) anchors that are

long enough to prevent the ram from tipping.

The equipment must be grounded. Grounding reduces

the risk of static and electric shock by providing an

escape wire for the electrical current due to static build

up or in the event of a short circuit.

Operation

Pressure Relief Procedure

1. Close the Air motor switch/slider valve (BF).

2. Turn the ram air regulator (BB) down to zero. Set

the ram director switch/valve (BC) to DOWN. The

the ram will slowly drop.

3. Jog the ram director switch/valve (BC) up and down

to bleed air from ram cylinders. When done, leave

the ram director valve in the neutral position.

4. Open the fluid drain valve (N) and/or dispensing

valve to relieve fluid pressure.

5. Close the main air valve (BA).

Flush Before First Use

The sanitary pump was assembled using sanitary

lubricant on moving parts and was tested in water. Flush

the pump thoroughly with an appropriate cleaning

solution or disassemble and sanitize the parts before

using the pump. See your separate pump manual for

complete flushing and cleaning procedures for a

sanitary pump. Check national, state, and local codes

for specific limitations.

Starting and Adjusting the Ram

1. On the exposed air controls, close all air regulators

and air valves.

2. Open the main bleed-type air valve (L).

3. Open the main air valve (BA), and set the ram air

regulator (BB) to 40 psi (2.8 bar, 0.28 MPa ). Set the

ram director switch/valve (BC) to UP and let the ram

rise to its full height.

4. Set a full drum of fluid on the ram base and center it

under the ram plate.

5. Remove the drum cover, and smooth the surface of

the fluid with a straightedge.

6. Secure the bag liner to the drum with tape or a strap

to prevent it from sliding into the drum.

7. Set the director valve to DOWN. Lower the ram until

the ram plate is about to enter the drum, and set the

valve to neutral. Reposition the drum as necessary

so the wiper seal does not hit the drum lip.

NOTE: To increase or decrease the speed of downward

travel on the ram plate, reduce the ram air pressure or

adjust the ram director switch/valve (BC).

8. Set the ram director switch/valve (BC) to DOWN,

and continue to lower the ram until the ram plate

contacts the fluid.

This equipment stays pressurized until pressure is

manually relieved. To help prevent serious injury from

pressurized fluid, such as splashing fluid and moving

parts, follow the Pressure Relief Procedure when

you stop dispensing and before cleaning, checking, or

servicing the equipment.

Remain clear of a moving ram to reduce risk of

serious injury of crushing from moving parts. Keep

hands and fingers away from the ram plate, pump

fluid inlet, and lip of the fluid container when raising or

lowering the ram to reduce risk of serious injury from

moving parts.

NOTICE

Do not use drums that have side bungs or large dents

with this ram. Rough bung openings or large dents will

damage the seal or stop the ram plate, resulting in a

runaway pump.
