GENERAL – The oil level adaptor kits described below are

used to attach the Sporlan oil level control to the sightglass

connection on the compressor housing. In addition to the

adaptor fitting, the kits contain the necessary bolts, nuts,

O-ring, and sightglass (except AOL-R-1). All Sporlan oil level

controls have the same 7 bolt universal flange connection. The

adaptor kits permit installing the oil level control onto com-

pressors with various threads or mounting hole configurations.

INSTALLATION – The overall procedure is to remove the

existing sightglass on the compressor, install the oil level

adaptor in its place, and then attach the oil level control to the

adaptor. This procedure requires the following steps:

1. Follow the procedure suggested by the compressor man-

ufacturer if the procedure is available. Otherwise the

following steps are suggested.

2. Shut off the power to the compressor involved and close

the suction service valve, or other valves to isolate the

compressor.

3. Release the refrigerant pressure in the compressor by

opening an appropriate connection (for example, loosen

the connection on the low pressure control). Drain the

oil to a level below the bottom of the sightglass. This can

be done through a drain plug, or by pulling the oil out

through the filler connection with a pump.

4. Remove the sightglass from the compressor. This will

require unbolting or unscrewing the sightglass.

5. Attach the adaptor to the compressor. The AOL-A and

AOL-C are machine threads and are sealed with an O-ring.

The O-ring will seal better if it is lubricated with a light film

of oil. The AOL-R-1 bolts to the compressor. See Figure 1.

NOTE: The bolt holes on the sightglass and oil level con-

trol are not equally spaced. Be sure to line the holes up

properly. The mark on the edge of the flange indicates the

top.

6. Attach the sightglass plate to the oil level control. The side

of the sightglass plate with the O-ring groove goes toward

the flange on the oil level control. The sightglass may be

attached to either arm of the oil level control. Bolts are

provided, as well as an O-ring and quad ring. Since both

of the mating parts contain a groove, the use of the O-ring

and quad ring combination permits getting a proper seal.

Tighten the bolts and nuts to approximately 6 ft.-lbs.

torque.

7. The oil level should always be adjusted to the level spec-

ified by the manufacturer. The oil level control can be

adjusted before use by following the instructions given in

Sporlan Bulletin 110-10 or Form SD-129 supplied with the

oil level control.

8. Attach the oil level control (with sightglass) to the adaptor

(already installed) using the bolts, nuts, and O-ring pro-

vided.

9. Connect the oil supply line from the reservoir to the flare

fitting on top of the oil level control.

10. Some oil level controls incorporate an oil equalization

fitting. If the system requires this connection, connect the

3/8” flare fitting on the side of the oil level control to the

oil equalization line. If the equalizer is not required, a cap

must be installed.

11. Refill the crankcase with oil to the proper level. Evacuate

the compressor and oil level control. Open the service

valve to pressurize the compressor and oil level system.

Test for leaks. Then start the unit following the manufac-

turer’s recommendations.

Sporlan oil level controls are listed by Underwriters

Laboratories for use with Refrigerants 134a, 22, 404A, 407C,

and 507. The controls have a maximum rated pressure of 650

psi (45 bar).
