12v portable diaphragm compressor

Advertisement

WARNING
Product surfaces become very hot during operation; allow them to cool
before handling.
The air stream from this product may contain solid or liquid material
that can cause eye or skin damage; wear proper eye protection.
Failure to follow these instructions can result in burns, eye injury
or other serious injury.
Each model has an automatic thermal protector that shuts the motor
off if it overheats. The motor will restart without warning once the
protector resets itself upon cooling.
This product can be installed in any orientation, provided that the flow
of cool, ambient air is not blocked. To minimize noise and vibration,
the nit should be mounted on a solid surface that will not resonate.
We recommend the use of shock mounts or vibration isolation
material. Inlet noise can be minimized by attaching an optional muffler.

Plumbing

Remove plugs from the IN and OUT ports. Connect with pipe
and fittings that are the same size or larger than the product's
threaded ports.

Starting

If the compressor is extremely cold, allow it to warm to room
temperature before starting. If the motor fails to start or slows down
when under load, shut it off and unplug it. Check that the supply
voltage agrees with the motor post terminals and motor data name
plate, and make sure the motor is turning in the proper direction.

General Maintenance

WARNING
When servicing, all power to the motor must be discharged and the
plug disconnected. All rotating components must be at a standstill.
Make sure that pressure and vacuum are released from the product
before starting maintenance. Check intake and exhaust filters after the
first 500 hours of operation. Clean filters, and determine how frequently
filters should be checked during future operation. This procedure in
particular will help the product's performance and service life.
1. Remove the end plate and filters. Inspect filters for rips, tears, cuts,
brittleness and excessive foreign material.
2. Clean filters if in good condition with compressed air. Reinspect for
wear conditions. Set filters aside.
3. Check the filter/muffler for compacted debris. If debris is present,
replace the filter/muffler.
4. Check the condition of O-ring. It should be soft and flexible.
Replace if it is not.
5. Remove and inspect the muffler box (not all models have a muffler
box). Clean the box and set it aside.
6. Check the gasket for cracks or tears. Install new gasket if any cracks
or tears exist.
7. Replace the muffler box.
8. Reinstall filters or install new filters if required. Reinstall the end plate.

Flushing the Muffler Assembly
Should excessive dirt, foreign particles, moisture or oil be permitted
to enter the compressor, the vanes will act sluggish or even break.
Flushing the muffler assembly should remove these materials. Do not
use kerosene or other combustible solvents. Use flushing solvent (part
no. AQ255) liberally to clean muffler parts.

Frequently Asked Questions (FAQ)

Is my compressor running too hot?
It is normal for a motor to run hot to the touch because the shell
transfers heat away from the motor windings.
However, improved materials used in motor manufacturing make the
"too-hot-to-touch" test obsolete. The best way to determine if a motor
is operating properly is to check the ampere (amp) draw. Each motor
has a nameplate listing full-load amps (FLA). If the tested amp draw
does not exceed the nameplate rating, its internal or external cooling
fan is working (if so equipped), and the ambient air temperature around
the motor is below 104°F (40°C). The motor is probably not running
hot, even though it is too hot to touch.
Even so, make sure that there is plenty of air flow around the motor,
and keep the area around the motor clear so that there is no blockage
of air flow to the motor. Also keep paint and other flammable materials
away from the motor.
How much will it cost to operate my compressor?
The cost of operation will depend on the length of time the compressor
is run each day. The following example is for a typical 1-hp, single-phase
compressor operated 24 hours a day at $.08 per kWh. The cost per
kWh will vary from location to location. Check your electric bill for the
cost per kWh.
9.7 amps x 115 volts = 1,115.5 watts (amps & volts are
on motor nameplate)
1,115.5 watts x 1,000 = 1.116 kW
1.116 kW x 24 hrs = 26.77 kWh
26.77 kWh x $.08 per kWh = $2.14 per day
Why is my compressor so noisy?
Compressor noise can be the result of vibration or mechanical noise.
1. Vibration is the intensification of normal compressor noise.
The noise should decrease if the compressor is firmly attached
to the foundation or if the compressor is completely isolated
by using a rubberized or cushioned base.
2. Mechanical noise is typically a high-pitched squealing sound.
The most common causes include worn motor bearings and
rubbing of the impeller against the compressor housing.
