General Requirements; Condensate Discharge Piping; Preparation For Use - DeWalt D55394 Instruction Manual

lIftInG
WARNING: Risk of injury from lifting. Unit weighs more than 160
lbs. (72.6 kg) Do not move or lift without assistance.
Always use two people when lifting and lift from the recommended
lift points (R).
MoVInG
1. Grasp handle (S) of compressor and lift compressor high
enough so unit can be rolled on the front tire(s).
WARNING: Risk of unsafe operation. Ensure proper footing and
use caution when rolling compressor so that unit does not tip or
cause loss of balance.
2. When location is reached slowly lower rear of compressor to
ground. Always store compressor in a horizontal position.

General requirements

The piping, fittings, receiver tank, etc. must be certified safe for at
least the maximum working pressure of the unit. Use hard welded or
threaded steel or copper pipes, cast iron fittings and hoses that are
certified safe for the units discharge pressure and temperature. Use
pipe thread sealant on all threads, and tighten joints thoroughly to
prevent air leaks. Do not usE PVC PlAstIC.
WARNING: Risk of bursting. Plastic or PVC pipe is not designed
for use with compressed air. Regardless of its indicated pressure
rating, plastic pipe can burst from air pressure. Use only metal pipe
for air distribution.

ConDEnsAtE DIsCHArGE PIPInG

If installing a condensate discharge line, the piping must be at least
one size larger than the connection, as short and direct as possible,
secured tightly and routed to a suitable drain point. Condensate
must be disposed of in accordance with local, state and federal laws
and regulations.
notE: All compressed air systems generate condensate that
accumulates in any drain point (e.g., tank, filter, aftercoolers, dryers).
This condensate contains oil and/or substances which may be
regulated and must be disposed of in accordance with local, state,
and federal laws and regulations.

PrEPArATIon For uSE

Pre-Start Checklist (Fig. 1)
1. Ensure the On/Off switch (C) is in the OFF position.
2. Plug the power cord into the correct branch circuit receptacle. See
Voltage and Circuit Protection under Installation.
3. Ensure air tank is drained, see Draining Air tank under
Maintenance.
4. Ensure the drain valve (J) is closed.
5. Ensure safety valve (I) is functioning properly, see Checking
safety Valve under Maintenance.
6. Check pump oil level, see Compressor Pump oil under
Maintenance.
CAUTION: Risk of property damage. Do not operate without oil or
with inadequate oil. D WALT is not responsible for compressor failure
e
caused by inadequate oil.
7. Turn regulator knob (F) counterclockwise until fully closed. Ensure
regulated pressure gauge reads 0 psi.
8. Visually inspect drive belt. Replace belt if frayed, cracked, or worn.
notE: Outer belt cover must be removed to inspect drive belt.
9. Visually inspect air hose, replace if needed.
10. Attach hose and accessories.
WARNING: Risk of unsafe operation. Firmly grasp hose in hand
when installing or disconnecting to prevent hose whip.
