ULTRA CLEAN LUBRICATED COMPRESSOR
INSTALLATION
1. ULTRA CLEAN LUBRICATED COMPRESSOR LOCATION REQUIREMENTS
The Ultra Clean Lubricated Compressor location should be level, accessible and well ventilated.
If the Ultra Clean Lubricated Compressor will be located in a confined space, provide adequate ventilation.
Electrical
(1) Line voltage must be within the limits of Figure 1 below. (Install a “buck-boost
transformer” if line voltage is not between these values.) Circuit breaker switches
must be 20 - 30 amp depending on model and voltage necessary.
(2) Local code may require you to provide one quick disconnect (safety switch) for the
compressor.
(3) See Figure 1 below for breaker size and line voltage.
CAUTION - Voltage must be 110/128 v or motor damage may occur.
CAUTION - Voltage must be 208/240 v or motor damage may occur.

2. INSTALLATION STEPS
This dental Compressor should only be installed by qualified personnel. Should any questions arise
during the installation, call Tech West Technical Support between the hours of 7:00 a.m. to 4:00 p.m.
(Pacific Standard Time).
Place the compressor in a clean, dry, well ventilated area, on a solid, level surface. Consider sound
level and insulate as needed. Be sure that adequate ventilation is available as the compressor is air
cooled. Ambient temperature in the equipment room should be within the temperature range of 40
degrees Fahrenheit minimum to 100 degrees Fahrenheit maximum.
(a) Check the shipping carton for damage. This could detect damage to the unit which might
otherwise be overlooked. Remove cardboard shipping carton.
(b) Remove the Lubricated Compressor from its shipping skid. Inspect the unit for damage.
Lubricated Compressors are shipped bolted to a pallet. This pallet is intended for shipping
only and should be discarded.
(c) Remove installation kit attached to pallet. It should contain the following:
(4) Isolation Feet
(1) Alternate Air Hookup Hose
(1) Bottle of Tech West Compressor Oil per Motor
(1) 5’ Flexible Air Hose
(d) Install isolation feet on tank legs.
(e) Remove shipping tape from spring-hinged oil filler cap(s).
(f) Install flexible hose to outlet on the compressor shut-off valve.
(g) Move compressor into place and level the motor platform.
(h) Install flexible hose to office air supply line.
(i) Install flexible hose to alternate fresh air supply.
(j) Wiring instructions:
1 Have all electrical connections made by qualified personnel only. All connections
should be in accordance with local codes.
2 Use the chart on page 1 to help determine the proper line and breaker size for
the unit that is being installed.

5. PERIODIC SERVICING
WEEKLY SERVICING
(a) Check the oil level. Refer to figure 2. Use only Tech West oil specially formulated for Tech
West Compressors.
DO NOT OVERFILL. Add oil only when the oil level remains below the center line of the oil-level
sight glass after the compressor has been idle for at least 5 minutes.
(b) Empty condensate drain bucket under the dryer.
MONTHLY SERVICING
(a) Crack the drain petcock on the bottom of the storage tank to check for water and drain if needed.
(b) Check pump-up times.
(c) Check the moisture indicator to see that it is still “blue”. If it is pink it is time to service the air dryer.
YEARLY SERVICING
(a) Repeat all of the monthly servicing.
(b) Change oil (part # CO-100).
(c) Replace the dessicant air dryer (part # RDC-100).
(d) Replace the ultra clean coalescing filter. (part # CFEO-375). This keeps drying system efficient.
(e) Replace alternate air filter (part # TIF-100). Reduces oil consumption and lengthens
compressor life and efficiency.
(f) Replace the moisture indicator on the compressor (part # MI-100).

4. START-UP STEPS
(a) Make sure the shut-off valve from the compressor tank is closed.
(b) Turn the breaker from the panel to the “ON” position.
(c) Turn power “ON” from the toggle switch on the compressor. Compressor should run quietly
and vibration free. The storage tank should start to build pressure.
(d) The compressor will run until the pressure gauge reads 100 psi. The compressor then will
automatically shut off and the dryer will purge with a quick blast of air.
(e) Using soapy water, check the compressor plumbing hook ups for leaks. Repair leaks if needed.
(f) Pressure test the entire plumbing system for leaks. Use the storage tank pressure gauge to
monitor a pressure drop. After the plumbing system has been pressurized for 30 minutes,
re-check the gauge for pressure drop. If there is a drop in pressure, find and repair all leaks
in the office plumbing.
AIR LEAKS ARE THE MAIN CAUSE OF COMPRESSOR FAILURES.
(g) Complete and mail in the warranty card for the compressor within ten days of installation.
