VMS-3 Manual 1 Revised 08/2010
The Racor VMS-3 Ultravoilet system is designed to provide a germicidal dosage of UV
radiation to suspended micro-organisms in clear water passing through a disinfection
chamber. The dosage is a function of both the intensity of the ultraviolet radiation from
the lamp and the time the water is exposed. Exposure time is related to the flowrate,
then higher the flowrate of water the shorter the exposure time. This system is rated for
maximum 3 GPM flowrate to obtain a full dosage. Water leaving the chamber is
instantly ready for use, no further contact time is required.
Special precautions must be taken since water is present near electrical
equipment. Always disconnect power before performing any maintenance
Avoid exposure to direct or strongly reflected germicidal ultraviolet rays.
Germicidal ultraviolet rays are harmful to the eyes and skin.
The VMS-3 is intended for use with visually clear water, not colored, cloudy or turbid
water that would impair the transmissivity of the radiation through the water. The VMS-
3 is not intended for treatment of water that has an obvious contamination such as raw
sewage, nor is it intended to convert wastewater to microbiologically safe drinking
water.
Influent water quality can negatively affect the performance of the system if the
transmissivity is impaired or if materials are present that deposit on the quartz sleeve.
For best results the following maximum concentration levels are recommended:
Turbidity 5 NTU
Manganese 0.05 mg/L
Total Suspended Solids 10 mg/L
pH 6.5 – 9.5
Color None
Hardness 6 GPG or 100 ppm
Iron 0.3 mg/L

INSTALLATION
The VMS-3 should be installed in a dry, sheltered location protected from direct weather
and protected from freezing. Depending on the air humidity and the temperature of the
water being treated, condensation is possible on the outside of the unit during
operation. Therefore installation location should be selected so that dripping
condensation cannot damage other equipment.
The unit should be installed closest to the point-of-use and after other water devices
such as de-ionizers, water softeners, carbon filters, prefilters, RO units, storage tanks,
pressure tanks and pumps. This reduces the chance of purified water being re-
contaminated by bacteria in any of these units. Remember, UV radiation does not have
any residual disinfection properties. The UV system should be connected to the cold
water service.
The UV system will function best when mounted horizontally with the connection ports
facing upwards. Either port can be used for the inlet or outlet. VMT offers an optional
set of mounting clamps as part number 90-1586. For complete design dosage air must
be purged from the chamber, which will happen naturally when the discharge port is
upwards. If the unit is mounted on a slope or vertically, use the higher port as the
outlet. Some air pocket may still remain above the outlet, this shortens the residence
time slightly but does not present a operational problem. If mounted vertically, it is
necessary to provide support below during maintenance as the sleeve or lamp can drop
down.
VMS-3 Manual 3 Revised 08/2010
The regular service required is lamp replacement (annually) which is a dry service. If
clearance space is not available for bulb changeout in place, the chamber must be
removed to a bench for the service. In that case, consider isolation valves and union
connections to simplify removal and reinstallation of the unit with minimum water
spillage.
Three power supply versions of the VMS-3 are available:
VMS-3-110V comes with a power cord and plug for a US standard 110/1/60 receptacle.
The ballast includes an LED indicator light that confirms the UV bulb is functioning.
VMS-3-220V comes with a “European” style plug on a cable for 220-240/1/50 power.
The ballast includes a LED indicator light that confirms the UV bulb is functioning.
VMS-3-12VDC comes with two wire leads from the ballast to be connected to a 12 Volt
supply. This version does not have any indicator LED for the bulb, but a indicator
window is provided on the end cap at the opposite end from the lamp connection.
The lamp is packed separately from the chamber. With the electrical supply
disconnected, push the lamp socket onto the lamp first and then slide the lamp straight
into the quartz sleeve without angling. Push the end cap on, over the static gland nut.
Attach the ground connector (if supplied) to the grounding tab on the chamber.
Special precautions must be taken since water is present near electrical
equipment. Always disconnect power before performing any maintenance
Lamp and Quartz Sleeve are easily damaged. Exercise care when
installing the lamp.

MAINTENANCE
Ordinary maintenance consists of lamp replacement on a 10000 hour or one year
interval and cleaning the quartz sleeve when conditions warrant.
Lamp Installation or Replacement
1) Disconnect power to the UV, and remove the ground connector (if equipped)
from the chamber
2) Remove the end cap by pulling cap of the static gland nut.
VMS-3 Manual 6 Revised 08/2010
3) Carefully withdraw lamp approximately 2 inches from the chamber. While
holding the lamp end, remove the lamp socket.
4) Carefully remove the lamp from the chamber by pulling straight out without
angling. Reinstall in the reverse order.
Germicidal ultraviolet rays are harmful to eyes and skin. Do not restore
power until lamp and end caps have been completely reinstalled.
Lamp and Quartz Sleeve are easily damaged. Exercise care when
handling the lamp.

Quartz Sleeve Cleaning or Replacement
1) Follow the steps in the previous section to remove lamp. Shutoff water supply
from the inlet and outlet ports of the chamber. If possible, drain all water from the
chamber.
2) Unscrew the static gland nuts from each end of the chamber. Avoid striking the
quartz sleeve with the static gland nut.
3) Remove the Teflon washer and O-Ring from both ends of the quartz sleeve. The
Teflon washer will sometimes stick to the static gland nut, but can easily be
removed.
VMS-3 Manual 8 Revised 08/2010
4) Carefully remove the quartz sleeve from the chamber. As you first pull the
sleeve, support the far end with your finger so that it does not drop to the bottom
of the chamber as it starts moving
5) Once removed, clean the quartz sleeve with alcohol or a detergent. Stubborn
stains can often be removed with a dilute solution of hydrochloric acid.
Follow all manufacturers’ instructions and precautions when handling
cleaners and chemicals.
6) Reassemble in the reverse order. While inserting, keep the quartz sleeve
parallel to the chamber, and as it nears the far end support with your finger.
Make sure the quartz sleeve protrudes an equal distance at each end. Be sure
that the O-rings are placed on the sleeve before the Teflon washer.
Tighten the static gland nuts firmly by hand only. Using hands tools can
easily break the quartz sleeve.
7) Prior to installing the lamp, connect the water supply and check for leaks. When
any leaks have been remedied, then install the lamp and connect the power
supply.
Germicidal ultraviolet rays are harmful to eyes and skin. Do not restore
power until lamp and end caps have been completely reinstalled.
