Troubleshooting: Electric Drain; Technical Data - Urrea COMP9303 Manual De Usuario

Ambient temperature too low. Install crank-
case heater kit. Relocate compressor to warmer
environment.
OIL IN DISCHARGE AIR (OIL PUMPING)
Lubricant viscosity too low. Drain existing lu-
bricant and refill with proper lubricant.
Lubricant level too high. Drain excess lubri-
cant.
Detergent type lubricant being used. Drain ex-
isting lubricant and refill with proper lubricant.
Piston rings damaged or worn (broken, rough
or scratched). Excessive end gap or side clear-
ance. Adjust piston rings.
Cylinder(s) or piston(s) scratched, worn or
scored. Repair or replace as required.
Crankshaft seal worn or crankshaft scored. Re-
place seal. Install shaft sleeve if required. Install
Bearing/Connecting. Rod Step Saver Kit.
Worn cylinder finish. Deglaze cylinder with
180 grit flex-hone.
OIL LEAKING FROM SHAFT SEAL
Crankshaft seal worn or crankshaft scored. Re-
place seal. Install shaft sleeve if required. Install
Bearing/Connecting. Rod Step Saver Kit.
SAFETY/RELIEF VALVE "POPS"
Clogged or dirty inlet and/or discharge line fil-
ter. Clean or replace.
Air leaks in air discharge piping. Check tubing
and connections. Tighten joints or replace as
required.
Defective safety/relief valve. Replace.
High pressure inlet valve leaking. Inspect,
clean or repair as required.
HIGH INTERSTAGE PRESSURE
High pressure inlet valve leaking. Inspect,
clean or repair as required.
LOW INTERSTAGE PRESSURE
Low pressure discharge valve leaking. Inspect,
clean or repair as required.
MOTOR WILL NOT START
Improper line voltage. Check line voltage and
upgrade lines as required. Contact electrician.
Wiring or electric service panel too small. In-
stall properly sized wire or service box. Contact
electrician.
Poor contact on motor terminals or starter
connections. Ensure good contact on motor
terminals or starter connections.
Improper starter overload heaters.
proper starter overload heaters. Contact elec-
trician.

OIL LEAKS
Defective oil pressure gauge. Replace gauge.
LOW OIL PRESSURE
Oil foaming in crankcase. Drain existing lu-
bricant, thoroughly clean crankcase, replace
lubricant.
Debris or other obstruction blocking oil flow.
Inspect/clean all oil passages.
EXCESSIVE OIL PRESSURE FLUCTUATIONS
(LESS THAN 5 PSI)
Oil foaming in crankcase. Drain existing lu-
bricant, thoroughly clean crankcase, replace
lubricant.
Debris or other obstruction blocking oil flow.
Inspect/clean all oil passages.
TROUBLE SHOOTING:
ELECTRIC DRAINING
VALVE WILL NOT CLOSE
Debris in solenoid valve prevents diaphragm
from seating. Remove solenoid valve, disas-
semble, clean and reassemble.
Short in electrical component. Check and re-
place power cord or timer as needed.
TIMER WILL NOT ACTIVATE
