Heavy Duty LE Rotator: Operation and Instruction Manual General Information
Congratulations on the purchase of your Heavy Duty
LE Rotator from Environmental Express.
The well-designed Heavy Duty LE Rotator delivers quiet, consistent and dependable
service. Large 6.25" x 6.25" x 12.75" stainless steel compartments accommodate most zero
headspace extractors and many styles of glass and plastic bottles. The box style design offers
a greater degree of safety than other styles of rotators.
The 12-position sample box is constructed of 14 gauge stainless steel reinforced at all
joints. The drive shaft is a full 1” in diameter to prevent any breakage, even with off-center
loads. Glass bottles containing extraction uid are shielded within the stainless steel box, not
rotating exposed in your laboratory.
LE1002 rotators use Brother® high efciency gear motors with self-lubricating
drive chains. Brother gear motors are designed in accordance with today’s most stringent
industrial standards to ensure longer service life and increased reliability. These all-helical
gears are among the quietest available and have the very high surface hardness required
to insure extended wear resistance commonly associated with EPA Method 1311. A selflubricating chain prevents slippage and requires no maintenance. Precise, constant speed
control is maintained during long hours of continuous operation.

Heavy Duty LE Rotator: Operation and Instruction Manual Setup and Operation
Placement of Your LE Rotator:
It is important that your rotator is situated in a safe, cool and dry environment.
The rotator weighs in excess of 172 pounds. With this in consideration, a solid
structure such as a counter top is an ideal location. If a sturdy counter top is not
available place the unit directly on the oor.
The unit should be placed far enough away from the front edge of the counter to
avoid possible contact with passersby.
Caution: Never allow the power cord to come into contact with rotating
components.
Avoid the use of extension cords. The unit should be placed close enough to
a grounded electrical outlet to enable use of the factory power cord. If it is
impossible to avoid use of an extension cord, make sure that you use a three-prong
14 AWG cord (or larger, i.e. 12 AWG) only. Using too small of an extension cord will
cause the cord to become very hot thus becoming a re risk. Failure to comply
could also cause serious damage to the electrical components of your rotator and
would void your warranty.
Basic Operating Procedures:
Once you have read this manual thoroughly, ensure that the power switch is in the
OFF position and that all obstacles and personnel are clear of the unit. Plug the
power cord into a 120VAC (LE1002) or 240VAC (LE1003) outlet, as described in the
previous section. Turn the unit on to conrm operation. The switch should always
glow amber during operation. Refer to the troubleshooting section of this manual
if the unit does not operate.
To load the compartments, turn the latch counterclockwise to release tension.
Open the lid and load the compartments.
Caution: It is important to offset your load (Refer to gure 1). For example, when
you are loading a 12-place unit, and you have 6 bottles to load, avoid putting all
six bottles on the front or back side of the box. Put the rst bottle in the back left
compartment, the second bottle in the second front compartment, the third bottle
in the third back compartment and so on.
By doing this, you will reduce the stress on the geared components thus allowing
your rotator to last longer.

Maintaining proper chain tension:
The chain needs to be inspected routinely to maintain proper chain tension.
If the chain develops 1/4" or more of slack it should be tightened using the
procedure below.
Steps to loosen chain:
1. Loosen the jam nuts using a 7/16" wrench.
2. Loosen the adjusting bolts, which are the bolts that hold tension against
the motor, with a 3/16" allen wrench.
3. Loosen the four bolts on the motor using a 1/4" allen wrench so that the
motor can be slid over.
Steps to tighten chain:
1. Tighten the adjusting bolts with a 3/16" allen wrench which actually
pushes the motor back into position. The chain should have no slack.
2. Tighten the jam nuts using the 7/16" wrench so that the motor will not
slide out of position.
3. Tighten the bolts on the motor using the 1/4" allen wrench.

Heavy Duty LE Rotator: Operation and Instruction Manual Troubleshooting Your Rotator
Heavy Duty LE Rotator Troubleshooting Guide:
The unit is plugged into the
wall outlet, the switch is on but
nothing happens.
The motor runs but the box does
not rotate.
The unit makes noise while
rotating.
Is the wall outlet “hot”?
1. Check the breaker box and try plugging another electrical device into
the outlet to see if it works.
Does the switch on the unit light up? If not, the internal circuit breaker may
have tripped.
1. Try turning the switch off and back on to reset the circuit breaker.
2. If the switch illuminates, but the unit still does not operate, unplug
the unit immediately and call 1.843.576.1147 or 1.800.745.8218 for
technical support. Only a competent electrician should attempt to
work on the electronics of this unit. Failure to comply may void your
warranty.
There could be several possibilities for this; stripped gears in the gearbox, a
broken chain, or loose set screws on pulleys are a few things to suspect.
If this problem has occurred, please contact technical support at 1.843.576.1147
or 1.800.745.8218. Please do not attempt to retrot any components. (If your unit
is still under warranty, you may be entitled to parts at no expense to you.)
After continued use over several years, it may be necessary to grease the two
bearings. This is a very simple process.
1. Unplug the unit, insert the grease gun tting over the zerk nipple
located on the bottom of each anged bearing.
2. Pump the grease gun until you notice a slight trace of grease discharge
out of the bearing insert.
This should correct the problem.
