Checking Safety Valve
_&WARNING: Risk of bursting. If the safety valve does not work
propedy_ over-pressurization may occu_ causing air tank rupture or
an explosion.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. NOTE: Ring may
be difficult to pull when air tank pressure is at 0 PSI (0 kPa). tf the
valve is stuck or does not operate smoothly, it must be replaced
with the same type of valve.
Draining Air Tank (Fig. 1)
_&WARNING: Risk of unsafe operation. Air tanks contain high
pressure air. Keep face and other body parts away from outlet of
drain. Use safety glasses when draining as debris can be kicked up
into face. _,WARNING: Risk from noise. Use ANSI S 12.6 ($3. f g) ear
protection as air flow noise is loud when draining.
NOTE: All compressed air systems generate condensate that
accumulates in any drain point (e.g. tanks, filter, aftercoolers,
13
dryers). This condensate contains lubricating oit and/or substances
which may be regulated and must be disposed of in accordance with
local, state, and federal laws and regulations.
1. Ensure On/Off switch (A) is in the OFF position.
2. Move compressor into an inclined position so drain valve (H) is
at the lowest point (this will assist in removing moisture_ dirt_ etc.
from air tanks)
CAUTION: Risk of Property Damage. Drain water from air tank may
contain off and rust which can cause stains.
3. Place a suitable
container
under the drain valve to catch
discharge.
4. Grasp black lever on drain valve
5. Slowly rotate lever to gradually bleed air from air tank.
6. When air tank pressure gauge reads 10 PSI (275.1 kPa), rotate
valve to the fully open position.
7. Close drain valve when finished.
Checking Air Filter Element (Fig. 1)
_WARNINO: Hot surfaces. Risk of burn. Outlet tube pump head_
and surrounding parts are very hot, do not touch (see the Hot
Surfaces identified in Fig. 2). Allow compressor to cool prior to
servicing.
1. Ensure ON/OFF switch (A) is in the OFF Position.
2. Allow unit to cool.
3. Remove filter cover (N) from base.
4. Remove etement from filter base...
5. Place new element back in filter
base. Purchase replacement parts
from your Iocai dealer or authorized
service center. Always use identical
replacement parts
