Badger LF User Manual
This manual contains installation, operation,
care, and repair instructions and user service
information for the RAMVAC® Utility Badger LF
dental vacuum system.
The main purpose of the Badger LF is to provide
a positive displacement, oil-less dry vacuum
system intended for use in a dental facility and
to be used by trained professional dental care
personnel only.
Badger LF is designed to provide trouble-free service
when installed, operated and cared for according to
the procedures set forth in this User Manual.
Vacuum is supplied to the system by a durable oil-
less rotary vane pump. A space-saving integrated
separation tank keeps liquid and foam out of the
pump. The E2 control provides precise electrical
control over run-time and shutdown operations
while vacuum is maintained at a uniform level by
the RAMVAC vacuum level control valve.
To ensure proper installation of the Badger
LF, carefully read all instructions contained
in this manual prior to installing, operating,
and servicing. For safety, pay close attention
to all notices, warnings, cautions and notes.
Section I Introduction
Safety Information
Classications
After the Badger LF is installed, please review the
features, operation procedures and care guide-
lines with the doctor's sta. Leave this manual in
the doctor's oice for future reference.
RAMVAC vacuum units are certied to ANSI/AAMI,
EX606-0-1:2005(R2012) and certied to CAN/CSA
Standard C22.2 No. 60601-11:08, and comply with
NFPA 99c Level 3 vacuum requirements, and are
manufactured in a FDA Registered ISO 13485:2003
certied facility.
– Type of protection against electric shock:
Class 1 Equipment
– Degree of protection against the ingress of
water: Ordinary
Here’s what you need to do to insure the safety
potential of this equipment is achieved:
• Make sure your equipment is installed ac-
cording to our written instructions and the
Installation Checklist is completed. If you have
purchased your RAMVAC from an authorized
dealer, the dealer is responsible for presenting
you with the completed checklist.
• Exhaust from dental vacuum systems can be
hazardous. Make sure the exhaust pipe is ter-
minated outside your building according to our
written instructions.
• Nitrous oxide and oxygen can be safely scav-
enged in the small concentrations typically
encountered in dental analgesia. The additional
air drawn into a properly installed and operated
Vacuum Unit will dilute these agents.
• Never use your RAMVAC to remove pure nitrous
oxide, oxygen or other oxidizing agents directly
from storage vessels or supply hoses. Large
concentrations may cause a re in the Vacuum
Unit and may cause an exhaust hazard.
• Never use this equipment in an OXYGEN RICH
ENVIRONMENT. Large concentrations may
cause a re in the Vacuum Unit and may cause
an exhaust hazard.
• Never use your RAMVAC for housekeeping
functions.
• Never use your RAMVAC to collect lab dust.

Turning the System On/O
Make sure all HVEs and saliva ejectors are
closed before turning the system o.
NOTICE
The RAMVAC can be run continuously throughout
the workday. Avoid wasting electricity by turning
o the RAMVAC if vacuum will not be needed for
an hour or more.
NOTE:No high voltage switching with the Badger LF.
NOTE:No special skills are required by the operator
to safely utilize this equipment. Contact the installing
dealer or RAMVAC if the following pages do not ade-
quately answer all questions.
IMPORTANT: Fluids in the separation tank are
hazardous. The Badger’s drain must be properly
connected to the facility’s sewer plumbing.
NOTICE
Shutdown Cycle
Turn the unit OFF at the end of each day. When
the unit is turned o, the power status light will
blink for 90 seconds, the tank will drain and the
Vacuum Pump will RESTART and run for a period
of 10 minutes. After this time has elapsed, the unit
will automatically turn o. This cycle is utilized to
prevent corrosion in the pump.
The vacuum level of the Badger LF is factory set
at 7 inch Hg (when all HVEs and SEs are closed).
Do not increase vacuum level above 12 inch Hg.
Vacuum Level
Separation Tank
The Badger LF contains an integrated separation
tank that will collect uids that are evacuated from
the operatory room. If the uid rises to an excessive
level within the tank, the Badger LF will disrupt vac-
uum for approximately 60 seconds in order for the
tank to drain. After this drain time has elapsed, the
unit will automatically restart and restore vacuum.

Section IV Care
Key points for trouble-free operation:
• Rinse vacuum lines daily with the recommend-
ed quantity of liquid and line cleaner.
• Check air lter on schedule.
• Exchange the pump head on schedule.
Foam may cause damage to the pump. Avoid
interruptions by insuring your cleaner is truly
“non-foaming”. Test by shaking the mixed
solution. True “non-foamers” will be bubble free.
CAUTION
Prior to performing any maintenance, proper
precautions should be taken to reduce the pos-
sibility of contact with infectious substances.
WARNING
Maintenance Overview
Preventative Maintenance Schedule IMPORTANT: Use of line cleaners outside of
this pH range will void the warranty.
CAUTION
Use of SlugBusterTM vacuum line cleaner is
highly recommended. SlugBuster is available
in powder and liquid forms, which can be or-
dered through any authorized RAMVAC dealer.

Cleaning the Vacuum System
NOTE:The Vacuum System should be cleaned daily.
NOTE:Check the treatment room solids separator
routinely and clean when dirty.
1. Just before turning o the RAMVAC, rinse vac-
uum lines rst with hot water - approximately
one quart through each high volume line and a
few ounces through each saliva ejector line.
2. Aspirate a few ounces of a dental vacuum line
cleaner through each vacuum line.
SlugBusterTM is highly recommended.
After Surgical Procedures
1. Aspirate a few ounces of an appropriate vacu-
um line cleaner, such as SlugBusterTM, through
the lines.
For Overhead Plumbing
1. Be sure to allow air to follow liquids before
closing vacuum valves.
Cleaners
Cleaners should have these qualities:
• Non-foaming
• Deodorizing
• Sanitizing
• pH between 6 and 10
Daily - Rinse vacuum lines
See "Cleaning the Vacuum System"
Every 1,000 hours* - Inspect air lters
See "Changing the Air Filters"
Every 12,000 Hours* - Exchange pump head
See "Pump Head Exchange"
* The "Maintenance" LED on the E2 Control will
illuminate every 1,000 hours.
* To reset the "Maintenance" LED after
maintenance has been performed, press and
hold the "Reset" button for 10 seconds until the

3. Do not heavily wet electrical components
4. Allow equipment to air dry or dry with a clean,
soft cloth.
Cleaning the Vacuum Unit
Changing Air Filters
NOTE:Inspect air lters every 1000 hours.
1. The Air Filter is accessed by twisting the
end cap on the Air Filter Housing in a count-
er-clockwise motion.
2. Replace lters every 2,000 hours or when
visibly dirty.
Section IV Care
Some parts/components on the
vacuum unit get hot during operation.
Provide the equipment ample time to
cool prior to cleaning.
CAUTION
A detailed instruction sheet will be sent with
the replacement pump.
NOTICE
Pump Head Exchange
NOTE:Inspect pump head every 1,000 hours.
Check Poly V-Belt
Disconnect power before any service to avoid
injury during dry down cycle. E2 can start
machine if still powered. Keep hands away
from moving parts.
CAUTION
NOTE:Inspect belt every 2,000 hours. Replace if
cracked or frayed.
