INTRODUCTION
Safety
This electromechanical equipment is designed to produce high pressure gas.
Operating personnel must follow these safety requirements at all times to
avoid injury to personnel or damage to property.
Keep away from live circuits. Do not attempt to replace components or make
adjustments unless the power to the compressor has been disconnected and
all pressure relieved.
Never operate with safety devices removed or disabled. This includes guards
for moving objects, protection from high temperature surfaces, pressure
relief valves, pressure switches, or covers over electrical components.
When compressing oxygen it is critical that surfaces in contact with oxygen
be kept clean and free from contamination, especially hydrocarbon
contamination or any flammable material. This compressor is shipped
oxygen clean and must be maintained that way to avoid the hazard of
explosion or fire.
Safety warnings are provided in a variety of forms, including:
Safety Labels-located on the equipment
Safety Messages- provided in this manual and proceeded by a safety alert
label, DANGER, WARNING, CAUTION, and NOTE.
DANGER You will be killed or seriously hurt if you don’t follow
instructions, and equipment damage is certain.
WARNING You may be killed or seriously hurt if you don’t follow
instructions, and equipment damage is certain.
CAUTION You can be hurt if you don’t follow instructions, and equipment
damage is likely.
NOTE Highlights a certain operation, maintenance condition, or statement,
which is useful but not associated with a known hazard, as indicated by a
warning or caution.

PERFORMANCE
The Microboost Compressor is designed to take oxygen at 0-25 psig and
compress it to 2200 psig. The discharge flow rate varies with inlet pressure
according to the chart below:

SAFETY
This electromechanical equipment is designed to produce high

DANGER
Keep away from live circuits. Do not attempt to replace

DANGER
Never operate with safety devices removed or disabled. This
includes guards for moving objects, protection from high

way to avoid the hazard of explosion or fire.
WARNING
Surfaces on the motor and compressor can become hot and may
cause burns when touched. Allow the equipment to cool before
handling it.

APPLICABILITY [ABCD]
CONTROLS AND FEATURES
Power Entry Module- The Microboost is connected to a source of
power using a power cord connected to the Power Entry Module
(conforming to IEC-320-C13). A power cord suitable for the intended
voltage, 115 VAC or 230 VAC, at 10 amps should be used to connect
the Microboost to the source of power.
Overload- The pushbutton reset overload is provided to protect the
equipment if the motor current draw exceeds 10 amps. A separate
automatic reset thermal switch is located inside the motor to protect the
motor from overheating.
Power On/Off Rocker Switch- The rocker switch is used to turn
power on to the Microboost control system. This switch is also used to
stop the unit manually when it is running.
Start Pushbutton- The momentary lighted pushbutton is provided for
starting the compressor. With the unit plugged into a source of electric
power and the On/Off rocker switch in the On position the Start
Pushbutton can be pressed to start the compressor motor. The
compressor runs until the pressure switch signals it to stop or until the
On/Off rocker switch is switched Off.
Pressure Switch- The pressure switch is provided to automatically stop
the compressor when the set pressure is reached. This is usually factory
set at 2200 psig. The switch is located inside the Microboost base and
is accessible for adjusting through a rectangular opening provided in
the underside cover.
Relief Valves- Relief valves are provided for all compression stages.
The first stage (set at 350 psig) and second stage (set at 1200 psig)
relief valves are located on the outside of the compressor as shown. The
third stage relief valve (set at 2200 psig) is located inside the
compressor base. These prevent pressures from rising to levels that
might cause damage.

INSTALLATION
The Microboost is a free standing package weighing 51 lbs and is
meant to be located in open air on a table, shelf, or on the floor. It
may also be mounted inside a frame or cabinet as long as sufficient
air circulation is provided to prevent overheating. Locate the
compressor in an area with good ventilation. An ambient
temperature of 90o F or less is preferable. Circulating air across the
compressor with an external fan will make it operate better and last
longer.
Rix recommends installing a flow check valve after the Microboost
discharge to prevent reverse flow when the compressor is off.
Pressure gauges should be installed at the suction and discharge to
help in monitoring performance and for troubleshooting.
Plug into a source of power that is protected for 15 amps (115 V)
or 10 amps (230 V).
Connect the compressor suction to a source of clean, dry gas
regulated not to exceed 25 psig. Filtration to 2 micron max particle
size is recommended. Particle contamination can cause failure.
Connect the compressor discharge to a high pressure cylinder or
manifold designed to handle pressures at 2300 psig. The customer
is responsible for designing and adequately protecting the
plumbing and equipment he attaches to the Microboost.
CAUTION
Exposed surfaces of the motor and compressor can reach 180oF
and will cause a burn if touched. Locate the unit in a safe location
where it is protected from human contact.
10 APPLICABILITY [ABCD]
OPERATION
Check that power is connected to the Microboost.
Check that the compressor suction is connected to a source of clean,
dry oxygen or nitrogen gas.
Check that the compressor discharge is connected to a fill system
suitable for 2300 psig and that there are no restrictions in the line.
Check that the compressor discharge is relieved of any pressure build-
up.
Caution
Do not attempt to start the compressor against
discharge pressure. Vent all gas pressure at the compressor
discharge prior to starting. If the compressor stalls it is
probably because there is residual pressure in the system.
Push the Power Onrocker switch to the ON position.
Push the Start pushbutton, the compressor should come on. Verify that
the compressor comes on and the Start pushbutton light is illuminated.
Periodically monitor the compressor for proper operation. Observe that
there are no leaks or unusual noises. Make sure there is adequate air
circulation around the compressor and that the location temperature
where the compressor is operating does not exceed 110oF.
Compressor Shutdown
Press the On/Off rocker switch to the OFF position.
