You are completely responsible for your own safety and the safety of those with you. Oasis Mfg. will not be responsible and will not assume any liability for indirect, incidental, or consequential loss, damage, injury, expense or inconvenience to property or persons as a result of use or misuse of this product.
Compressor and motor surfaces become extremely hot during use! To avoid serious burns, do not touch any part of this equipment, except for the on/off switch, with bare hands during or for 30 minutes immediately following operation.

1. Only persons who have read and understand these instructions should be allowed to use this compressor.
2. The air produced by this compressor is not fit for human or animal consumption and it must not be used to provide a breathing air supply.
3. Do not operate compressor with any damaged hose(s) or after the compressor or attachments have been dropped or damaged.
4. Never use while sleepy or drowsy.
5. Do not use near flames.
6. Do not pump anything but air.
7. Never point any air nozzle at any person or animal. Serious injury may result.
8. Do not leave unattended during use.
9. Use an appropriately sized fuse to protect both vehicle and compressor from a short circuit condition. We DO NOT recommend the use of circuit breakers.
10. Never rely on a safety valve to protect this compressor in place of a pressure switch. A pressure switch must be used to control the compressor.
11. Overheating, short circuiting and fire damage will result from inadequate wiring.
12. If the equipment starts to vibrate abnormally, slows down or stalls, STOP the motor immediately.
13. Never operate near a flammable gas or liquid. Never store flammable liquids or gasses in the vicinity of the compressor.

15. Disconnect power and release all pressure from the system before attempting to install or perform maintenance to the system (tank, air lines, etc.).
16. Be sure any tools or attachments are compatible with the pressure and flow rate of this equipment.
17. Check all fasteners and electrical connections at frequent intervals for proper tightness and cleanliness.
18. Do not attempt to disassemble, modify or repair this equipment.

INSTALLATION

Mounting location should be:
Upright – Mount the compressor so the intake and output fittings are located on top of the compressor for proper lubrication, do not mount the unit on its side.
Dry – Avoid mounting in a location that may become submerged if possible. The air intake filter must be mounted in a dry location. Use a length of 5/8” heater hose to remotely mount it if necessary. If unit is submerged, allow motor to drain thoroughly before use!
Cool and well ventilated – This will allow the compressor to run for longer periods.
Away from materials that can melt or are combustible – Compressor gets extremely hot during operation.
Level – Compressor must be as level as possible during operation for proper lubrication.
Close to battery – The shorter the power cables are, the better your performance will be. New ring terminals and heat shrink are available from the manufacturer if you wish to shorten the power cables. Mounting an isolated auxiliary battery next to the compressor and cutting the cables down to minimum length will provide maximum performance. Use a deep cycle battery.
If you must mount the compressor farther away than the 10’ power cables will allow, use #0AWG wire for runs up to 20’ instead of #4AWG cable provided. Be sure charging system is in top condition, and optimized to deliver maximum charge current to battery. Some applications may require an upgrade to the charging system and/or multiple batteries.
Caution: Do not change power cables to a smaller gauge size. Extreme fire danger will result!
Protect from corrosive environments – Exposure to de-icing chemicals used on winter roadways, marine environments, etc., will cause corrosion and failure if left unprotected. If possible, mount compressor in an enclosure that also prevents heat build-up. If the compressor is mounted to the chassis of the vehicle, use an adequate splash guard along with preventive maintenance (see note about corrosion in the Maintenance section).

Parts list

This package should contain the following:
Compressor, air filter, 3/8” studs, nuts, flat washers, lock washers, Fuse, fuse block, cable lugs and heat shrink.

1. Temporarily position the compressor in the mounting location to ensure fit and adequate clearance. Be sure location can support compressor properly.

2. Using the template, drill four 7/16” diameter holes.

3. Mount compressor using the four 3/8” studs on the bottom of the compressor (finger tight ONLY into compressor), and secure with nuts and lock washers.

4. Turn compressor switch off. Connect the black cable to the battery’s negative terminal, and the red cable through an appropriate size fuse to the battery’s positive terminal.
   Warning: Reverse polarity (red to negative and black to positive) WILL DAMAGE THE MOTOR CONTROLLER!

5. Install a pressure switch rated at 200 psi or less, on the tank (if using one) or air line (if not) coming from compressor, to automatically control the compressor as pressure is used from the system. A dash mounted switch may also be used to provide manual
   control as well. Refer to the wiring diagram for details.
   Note: The compressor can be controlled by two methods: either by connecting terminal +C (positive control) on the motor controller to a positive battery source (12 or 24 volt) such as an upfitter dash mounted switch, or by connecting terminal –C (negative control) to a ground source such as the chassis, see wiring diagram.

6. Be sure all electrical connections are clean and secure. Loose or dirty connections will result in poor performance.

7. Install air filter or fitting for a filtered intake line into the suction port. Do not use Teflon tape! Pieces of tape can get sucked into the compressor valves. Note that inside the suction port is a filter that has the appearance of metal shavings. Do not remove it, it is supposed to be there!

8. Compressor is shipped with oil. Check oil sight glass after compressor has been sitting level for at least one hour. Hold a spirit level next to the unit if necessary to ensure it is level. If no oil is visible in window, remove the oil plug from the side of compressor (the suction side). This will relieve the crankcase and allow oil in the overflow reservoir to drain back into the crankcase. If oil level is not visible within a few minutes, add oil until it is visible in window. Use a full synthetic 30 weight (ISO 100) air compressor oil.

9. Install a high temperature air line from discharge port in the head of the compressor to a tank or point of use fitting. Warning: Do not tighten fitting to more that 20 ft/lbs (finger tight plus no more than one full turn) into the compressor head. Doing so may crack the head! We recommend the use of Loctite #567 high temp pipe sealant.

We recommend the use of an unloader valve if the compressor will be operated at pressures of 150 psi or greater. Unloader valves are available from the manufacturer.
For installations involving tanks, some applications may require the use of a one way check valve at the output of the compressor to prevent air flow back into the compressor, and an air line filter at the output of the tank to separate oil mist and moisture out of the air line. Both items are available from the manufacturer.
If you are unsure about any part of installation or operation, contact the manufacturer for clarification.

OPERATING INSTRUCTIONS

Turning the on/off switch to the “on” position will start the compressor. It may now be used to inflate tires, operate air tools, etc.
Occasionally small amounts of smoke can be seen coming from the unit as it warms up. This is normal.
Since this is an oil bath type compressor, some oil discharge is normal. If an application requires oil free air delivery, a coalescing air line filter may be required. Filters are available from the manufacturer.
This equipment draws large amounts of current during operation. We recommend your vehicle engine be left running to prevent excessive discharge of your battery, and to maximize compressor performance. Some applications may require the use of a throttle positioning device to maintain engine RPM at a point where the alternator delivers maximum output.

Note:
This unit is equipped with microprocessor motor control module. It monitors voltage level, motor current, and controller temperature. It will shut the compressor off if any of the following conditions exist: voltage too high or low, current too high or low, or  controller too hot. If the controller goes into any of these protection modes, the lamp in the rocker switch will flash per the following chart. If multiple faults are present, there will be one long pause between each sequence. To reset the circuit, turn the rocker switch to the off position, then back to the on position. This circuit is designed to protect the compressor motor from damage due to stalling.
It is not designed to protect a battery!

MAINTENANCE

Check oil level daily. If no oil is visible in window, remove the oil plug from the side of compressor (the suction side) and add oil until visible in window. Use a full synthetic 30 weight (ISO 100) air compressor oil.
If compressor is exposed to a corrosive environment, all exposed electrical components, especially the motor brushes and motor terminals, should be treated with protective products such as DeoxIT or Fluid Film on a regular basis.
Change air filter element annually. Elements are available from the manufacturer.
All repairs should be performed by the manufacturer. Any attempt to disassemble or repair the unit may void warranty.
