SAFETY PRECAUTIONS
To ensure that the safety potential of this equipment is achieved, make sure equipment is installed according to
written instructions and that the provided INSTALLATION CHECKLIST & WARRANTY INITIATION form is completed. If
vacuum was purchased from an authorized dealer, the dealer is responsible for providing the completed checklist.
WARNING
Do not modify this equipment without permission from Ramvac. Unauthorized modification will void the warranty
and could result in serious injury. If this equipment is modified, appropriate inspection and testing must be
conducted to ensure continued safe use of equipment.
Electrical shock could occur as a result of improper grounding. This product must be grounded according to NEC
regulations and local codes.
The vacuum unit should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is
necessary, the vacuum should be observed to verify normal operation in the configuration in which it will be used.
Exhaust from dental vacuum systems can be hazardous. Make sure the exhaust pipe is terminated outside of your
building according to Ramvac's written instructions.
Nitrous oxide and oxygen can be safetly scavenged 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 the vacuum to remove pure nitrous oxide, oxygen or other oxidizing agents directly from the storage
vessle or supply hoses. NEVER USE THIS EQUIPMENT IN AN OXYGEN RICH ENVIRONMENT. Large
concentrations may cause a fire in the vacuum unit and may cause an exhaust hazard.
Never use the vacuum to scavenge flammable anesthetic gases. Even small concentrations may cause a fire in
the vacuum unit.
Portable RF communications equipment (including peripherals such as antenna cables and external antennas)
should be used no closer than 30 cm (12") to any part of the vacuum, including cables specified by the
manufacturer. Otherwise, degradation of the performance of this equipment could result.
Property damage and/or personal injury may result if directions are not followed or OEM parts are not used.
Always turn off vacuum and remove power from unit when servicing. (Turn off power at disconnect or service
breaker.)
Danger of fire or explosion when using flammable substances.
Never leave children unattended when vacuum is in use.
CAUTION
Never use the vacuum for housekeeping functions.
Never use the vacuum to collect lab dust.
Dispose of used lubricating oil responsibly as recommended in SECTION V - CARE & MAINTENANCE of this user
guide.
SECTION I - INTRODUCTION

CAUTION
The vacuum has several guards designed to protect against accidental contact with dangerous components. Do
not remove these guards until power has been disconnected/turned off from the equipment. If service is required
with the guard removed and the power on, it should only be performed by a qualified service technician. Always
replace any guards that have been removed for service or that may have been damaged.
During installation, always ensure all electrical, plumbing or other utilities are properly located to avoid possible
tripping or falling hazards. Always follow all local, state and national building codes, as well as any applicable
workplace safety regulations.
Use of a plug for electrical service is not recommended. Incorrect connections will cause a drop in line voltage
and/or loss of power. Overheating could result.
The EMISSIONS characteristics of this equipment make it suitable for use in industrial areas and hospitals
(CISPR 11 class A). If it is used in a residential environment (for which CISPR 11 class B is normally required) this
equipment might not offer adequate protection to radio-frequency communication services. The user might need to
take mitigation measures, such as relocating or re-orienting the equipment.
NOTICE
Medical electrical equipment needs special precautions regarding electromagnetic (EMC) compatibility and needs
to be installed according to EMC information. (See EMC INFORMATION provided in this manual.)
The use of accessories, transducers, and cables other than those specified, with the exception of transducers
and cables sold by the manufacturer of this device as replacement parts for internal components, may result in
increased emissions or decreased immunity of the vacuum.
Portable and mobile radio frequency (RF) communications equipment can affect medical electrical equipment.
There may be an instance, in low-humidity environments, that the user of the dental compressed air system may
cause the vacuum to stop as a result of electrostatic discharge (ESD) energy. To remedy this issue, cycle the ON/
OFF switch on the bottom of the control box.

LOW-VOLTAGE REMOTE SWITCHING
NOTICE Maximum wire length for 18-gauge wire is 500 feet.
Low-voltage remote switching is used to turn the system on and off from a remote location. Ramvac vacuums are
manufactured to continuously run throughout the workday. To conserve power, turn off vacuum if it will not be needed
for an hour or more. Power the vacuum off at end of day. The tank will drain only when no vacuum is present; the
vacuum must be turned off at least once per day.
