Safety Warnings

Halogenated Hydrocarbon Fluid Hazard

NEVER USE halogenated hydrocarbon solvents or fluids

containing such solvents in this equipment. Examples
of halogenated hydrocarbon solvents are: 1,1,1
trichloroethane, methylene chloride, fluids with the
prefix “fluoro-“, “chloro-“, “bromo-“ or “iodo-“, etc.
These solvents can cause an explosion when used with
aluminum components in a pressurized fluid pumping
system. The resulting explosion may cause death, serious
bodily injury or substantial property damage.

Pressurized Equipment Hazard

High pressure fluid can cause serious injury. This equip­ment is for professional use only. Observe all warnings.
Read and understand all applicable instruction manuals
before placing equipment into service.

Equipment Misuse Hazard

GENERAL SAFETY – Any use of the reservoir and related

accessories not consistent with that described in this
manual, such as modifying or removing parts, over­pressurizing, using incompatible fluids and chemicals,
or using worn, damaged or incompatible parts can
cause them to rupture resulting in serious bodily injury,
including fluid splashed in the eyes or on the skin, or fire,
explosion or other property damage.

NEVER alter or modify any part of this equipment, as
doing so may cause it to malfunction.

CHECK all reservoir components regularly and replace
any worn or damaged parts with only EFD supplied or
approved parts. BE SURE that all dispensing equipment
and accessories are rated to withstand the maximum
operating pressure of the reservoir.

Personal Protective Equipment

Wear all protective eyewear, gloves, clothing and respirator
as recommended by the manufacturer of the fluid used.

Safety Warnings 3

Continued on next page

4 Safety Warnings

System Pressure

NEVER exceed the maximum reservoir pressure of 6.9 bar

gauge (100 psi). The maximum supply pressure to the
reservoir regulator must not exceed 10.4 bar gauge (150
psi).

BE SURE that all dispensing equipment and accessories
are rated to withstand the maximum operating pressure
of the reservoir.

If an EFD five-micron filter regulator #2000F755 is not
used, be certain your plant air is properly filtered and
dry. Oil or particulate in the air supply line can cause
erratic performance and can contaminate the fluid to be
dispensed if it is not properly filtered.

Fluid Compatibility

BE SURE that all fluids, including their vapors, contained

in the reservoir are compatible with all materials on the
wetted materials list on page 14 of this manual. Read
the fluid manufacturer’s literature, including the MSDS
(Material Safety Data Sheet) and observe all warnings
before pouring the fluid into the reservoir.

Fill Level

DO NOT overfill the reservoir. The recommended maximum

fill level is 38.1 mm (1.5") below the top of the liner.

Tipping and Dropping Hazard

BE SURE that the reservoir is placed on a hard, level surface

and that all tubing lengths are of sufficient length to
allow free motion of all movable components attached
to the reservoir. DO NOT pull on tubing to move the
reservoir.

Tipping the reservoir or otherwise supporting it on its
side can cause fluid to enter both the pressure regulator
and pressure relief valve and interfere with their normal
function. A damaged pressure regulator and/or damaged pressure

relief valve may lead to an over-pressure condition within the

Safety Warnings 5

reservoir. If the reservoir tips or the pressure regulator

and/or pressure relief valve otherwise become blocked,
they must be replaced with EFD supplied or approved
parts before returning to service.

Dropping the reservoir from any height can damage the
pressure regulator, pressure relief valve, and fittings
and/or compromise the integrity of the reservoir body
and cover. A damaged pressure regulator and/or damaged pressure

relief valve may lead to an over-pressure condition within the
reservoir. A damaged reservoir body and/or cover can be an explosion
hazard. If the reservoir falls from any height, it must be

thoroughly inspected for cracks or damage to the pres­sure regulator and/or pressure relief valve. If damage to
a component is suspected, it must be replaced with EFD
supplied or approved parts before returning to service.

Tubing Safety

Pressurized tubing can be very dangerous. Tubing whose
integrity is compromised due to any kind of wear, damage
or misuse can develop a leak, spraying the contents of
the tank at high pressure. This spray can enter the eyes
or cover the skin or cause other serious bodily injury, fire
or property damage.

Before pressurizing the reservoir:

1. BE SURE all fluid connections to the reservoir are
properly secured.

2. Examine all tubing for cuts, wear, bulges and leaks.
If any of these conditions exist, replace the tubing
immediately with EFD supplied or approved tubing.
Do not try to repair a damaged tube.

3. BE SURE that the fluid to be dispensed is compatible
with the tubing. Contact the fluid manufacturer
and confirm that the fluid is compatible with the
tubing material specified on page 15 of this manual.

4. BE SURE that the tubing will not be exposed to
operating temperatures in excess of 50 °C (122 °F) or
below 0 °C (32 °F) in the application.

10 Pressure Relief Procedure

Pressure Relief Procedure

To reduce the risk of bodily injury, including fluid
splashing into the eyes, NEVER attempt to open the reser­voir without first performing this procedure.

1. Slide the shutoff valve ➀➀on the air input hose to
exhaust. (Figure 1)

2. Actuate the air relief valve ➁➁. Hold the relief valve
open until any hissing sounds end.

3. Confirm that the indicated gauge pressure is zero ➂➂.
If the gauge reads zero, slowly release the cover
clamps

➃➃

and remove the cover as shown in Figure 2.

4. If the pressure gauge does not read zero after performing Steps
1 and 2, remove the air input hose from the air regu­lator and set the regulator pressure to zero. A hissing
sound should be heard from the regulator during
this step. Once the gauge reads zero, return to Step

3. Do not use the reservoir until the air relief valve
is replaced.

12 Setup

Setup

1. Install the input air tee into the EFD five-micron filter
regulator supplied with the ValveMate™controller.
Maximum pressure is 100 psi (6.9 bar). If no air filter
regulator is available, specify #2000F755. (For cyano­acrylates, add coalescing filter regulator element
#756FLT.)

2. Set up the EFD dispense valve and controller as
described in their operating manuals.

3. Remove the tank cover and temporarily store it by
reattaching one of the clamps (Figure 2). When refilling
the tank, use a cup (not included) to catch any excess
material that drips from the feed tube.

4. Cut the fluid feed tubing to an appropriate length
plus 8" to go inside the tank. Cut one end of the feed
tubing at an angle and push the tubing through the
bulkhead fitting and adjust the inside length so it sits
just off the bottom of the tank. Tighten the compres­sion nut to secure the tube.

Note: 626DT series tank reservoirs can use either 1/4"
or 3/8" OD fluid feed tubing. With 1/4" fluid feed tub­ing, use reducer fitting #62518PT (Figure 3).

Figure 2.

#62518PT reducer

Setup 13

5. Attach the other end of the fluid feed tubing to the
dispense valve as described in the valve operating
manual.

6. Fill the tank either by pouring material directly
into the tank liner or by removing the liner and
placing a manufacturer’s bottle inside the tank.

7. Install the cover. If you are using a manufacturer’s
bottle, ensure the feed tube is inserted into the bottle.
(Figure 4).

8. Tighten the cover clamps securely.

9. Attach the black quick-connect on the air hose to
the black quick-connect on the tank air regulator,
then attach the white quick-connect on the air
hose to the input air tee. Slide the shutoff valve to
the “pressurize” position.

10. Adjust the tank air regulator to a pressure sufficient
to dispense material. Typical settings are 2 to 5 psi
(0.1 to 0.3 bar) for low viscosity and 40 to 80 psi
(2.8 to 5.5 bar) for high viscosity fluids.

Refilling

To open the tank, follow the Pressure
Relief Procedure on page 10. Follow
Setup steps 6-8 to refill, then close the
air relief valve and slide the shutoff
valve to the “pressurize” position.

Note: When pressurized, it is normal to
hear a hissing sound coming from the
regulator. This is due to the precision
constant-bleed regulator feature.

14 Wetted Materials/Troubleshooting

Wetted Materials List

The following materials come in contact with the fluid dispensed

during normal use:

1. Polyethylene (fluid feed tubing and tank liner)

2. Cast Aluminum Alloy 356.0 (reservoir body and cover)

Troubleshooting

Trouble: Cannot set or maintain reservoir pressure

Possible Cause Solution

Cover clamps Make sure all cover clamps are secured

not secured hand-tight.

Leaking feed tube Make sure bulkhead fitting is assembled

bulkhead fitting per instructions. If leak continues after

proper installation, replace with new
fitting.

Damaged cover O-ring seal Replace damaged O-ring seal.

Damaged/malfunctioning If air relief valve is not functioning

air relief valve properly, it MUST be replaced before

returning the reservoir to service.

Kinked air supply line Make sure air supply line is straight and

protected from other equipment.

Shutoff valve set to exhaust Make sure shutoff valve shuttle is set to

“Pressurize”.

Cover seal surface Make sure cover sealing surface is free

dirty or damaged from debris or other contamination. The

reservoir should be replaced if there is a
cut or gouge in the sealing surface deep
enough to prevent the tank from
achieving its set pressure.

Damaged/malfunctioning Replace with new air regulator.

air regulator

Air supply Supply system regulator is required. EFD

is fluctuating supplies the model 2000F755 filter regu-

lator. Set this regulator 10 psi (0.7 bar)
below the lowest plant air fluctuation.

Maintenance & Cleaning/Accessories 15

Maintenance and Cleaning

The 615DT and 626DT Series Reservoirs are very simple
and reliable reservoirs that require little routine mainte­nance. However, the following items should be checked
monthly to assure continued trouble-free operation:

1. The air relief valve must be cycled with the reservoir

pressurized at least once per month. The valve
should operate smoothly with normal finger pres­sure. If the valve requires excessive force to operate
or is visibly contaminated, it must be replaced prior
to returning the reservoir to service.

2. The condition of the O-ring should be checked for

cuts, tears, etc. Any spills on the sealing surface of
the reservoir should be wiped clean immediately with
a soft, damp cloth and mild soapy water.
