ULTRA CLEAN OILLESS COMPRESSORINSTALLATION

1. OILLESS COMPRESSOR LOCATION REQUIREMENTS

The Ultra Clean Oilless Compressor location should be level, accessible and well ventilated.

If the Ultra Clean Oilless 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.) Provide a separate line for each motor. Circuit breaker switches must be 20 - 40 amp depending on model and voltage necessary.

(2) Local code may require you to provide one quick disconnect (safety switch) for each compressor motor.

(3) See Figure 1 below for breaker size and line voltage.

CAUTION - Voltage must be 208/245 V or motor damage may occur.

CAUTION - Voltage must be 110/120 V or motor damage may occur.

2. INSTALLATION STEPS

This dental Compressor should only be installed by qualified personnel. Should any questions ariseduring 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 soundlevel and insulate as needed. Be sure that adequate ventilation is available as the compressor is aircooled. Ambient temperature in the equipment room should be within the temperature range of 40degrees 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 Oilless Compressor from its shipping skid. Inspect the unit for damage.Oilless 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) 6’ Flexible Air Hose

(d) Install isolation feet on tank legs.

(e) Move compressor into place and level by observing bubble level on compressor platform.

(f) 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.

(g) Install the air line from the compressor tank to the building supply.

(h) Install the 3/4” flex alternate air hose from the compressor to a fresh air supply.

4. SAFETY PRECAUTIONS

• Keep fingers, foreign objects and clothing free from rotating parts and do not touch hot surfaces.

• Never attempt to service an operating unit.

• Isolate unit from system pressure and relieve backpressure before servicing

• Disconnect all power before servicing. The thermal protector in single phase motors automatically starts motor when device resets.

USE OF THIS PRODUCT IN OR NEAR EXPLOSIVE ATMOSPHERES, OR FOR

PUMPING MIXTURES OTHER THAN ATMOSPHERIC AIR MAY CAUSE AN

EXPLOSION OR FIRE, RESULTING IN PERSONAL INJURY OR DEATH.

5. 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.

(g) Complete and mail in the warranty card for the compressor within ten days of installation.

AIR LEAKS ARE THE MAIN CAUSE OF COMPRESSOR FAILURES.

5

7. PERIODIC SERVICING

MONTHLY SERVICING

(a) Remove the purge bucket and empty as needed(b) Crack the drain petcock on the bottom of the storage tank to check for water and drain if needed.(c) Check moisture indicator to see that it is still “BLUE”. If it is pink, it is time to service the air dryer.(d) Check pump-up times of the compressor.(e) Check intake air supply filters. Replace filters as needed.

YEARLY SERVICING

(a) Repeat all of the monthly servicing.(b) Replace the dessicant in the air dryer.(c) Replace the alternate air filter.(d) Replace the intake filters on the Oilless compressor head. (Part #s (1HP: TIF-100) (2HP: TIF-200))(e) Replace the moisture indicator on the compressor. (Part #: MI -100)(f) Check the coalescing filter and change if needed. (Part #: CFE-375)

6. GENERAL SERVICE INFORMATION

For parts and service on VX series products contact the nearest authorized Tech West distributor. Toexpedite appropriate service, be prepared to provide the unit model number, identification number,and serial number found on the nameplate located on the front of the unit motor.

Component life operating at continuous duty & maximum pressureLife of the rings and skirts is difficult to predict due to many conditions which directly influence wear.Some of these conditions may include ambient air temperature, air cleanliness, operating pressure,piston stroke on the particular model being utilized, duty cycle, maintenance of filters, etc.

Because of these various factors it is appropriate to generalize on component wear life and choosesome conservative estimates for most standard applications.

With these conditions in mind, we recommend the following preventative maintenance schedule.
