Honeywell Honeywell Air Compressor WP241C WP241C

Visually check the air intake filter on l/3- to 2-hp (0.25 to 1.49 kW) compressors for build-up of foreign material on a routine basis. A dirty filter causes excessive oil consumption, replace it

The 3-hp (2.24 kW) and larger units use the Quincy Air Maze filter silencer, which is checked for dirt by removing it from the unit and holding a strong light against the intake openings. Light should be visible when observing from the inside of the filter. ash the filter in nonflammable solvent or in warm, soapy water

- Change prv filter on 7-l/2 hp (5.6 kW) only

CAUTION: Allowing system pressure to drop to zero during replacement of element or gage tap installation will cause all actuators in the system to assume their normal position. Study system, drawings for any critical problems that may result

To change a filter in the 7-l/2 hp (5.6 kW) refer to Fig. 1. Shut off air to filter at point (A) and bleed down housing by manually operating drain trap (B). Remove wing nut and clamp ring (C) from housing and remove housing and automatic drain. Remove knurled nut at bottom of filter and replace filter. Reassemble, taking care that O-ring seal on bottom side of cover has not been disturbed. Turn on air slowly, checking for leaks

- Dirty operating environment may require changing these items more often. The three-month checks will ncover any need for more frequent replacement;

- Drain water from tank and filter bowls

To drain tank, open drain cock, located in the middle of the tank at one end. Allow a few seconds to purge the tank of water. Weekly draining is usually the minimum requirement

NOTE. The frequency of draining depends on climatic conditions. In humid climates, daily draining may be necessary

Consider adding the Honeywell AK3485 automatic drain kit

- Check tension and condition of belts (see Fig. 2)

Hand pressure should depress the belt about 1/2 inch (13 mm). Tighten the belt just enough to prevent slippage. Adjust tension by loosening the motor hold-down bolts, moving the motor until tension is correct, then retighten the bolts. Insure that belt and pulleys are aligned. Replace worn or frayed belts

- Check oil level and pressure on 1 hp (0.75 kW) and larger compressors

Quincy units use splash lubrication on the 1/3 to 3/4 hp (0.25 to 0.56 kW) units and pressurized lubrication on 1 hp to 7-l/2 hp (0.75 to 5.6 kW) units; Stop both pumps

Remove and wipe off dipsticks; Reinsert dipsticks

If necessary, add oil through dipstick port

Use oil in accordance with Table 1

Table 1. WP241 Dual Air Compressor Specifications

4 oz (118 ml) - WP241Y (Splash Lubrication System)

28 oz. (828 ml) - WP241B (Splash Lubrication System)

Lubricate the motor annually in accordance with instruction on nameplate;

WARNING: Personal injury could result from starting a unit not containing oil

Remove the drain plug and dipstick and allow oil to drain completely

Ordinarily, a crankcase need not be flushed

If flushing seems necessary, use a nonflammable solvent (available at most auto parts stores)

Replace plug and refill according to Table 2
