WARNING
The refrigeration unit engine produces dangerously high noise levels reaching 96 dB (A) at
the service position. Approved hearing protection must be worn any time personnel are
within 12 feet of an operating unit to avoid temporary or possibly permanent hearing damage.
Engines have fast moving parts that can injure hands, fingers, etc. Take special care while in
operation. Engine parts, particularly the exhaust system, can be very hot and cause severe
burns. Do not touch until engine is shut down and cooled off. Avoid spilling fuel or oil on
hot engine parts which could result in a fire.
h. Place the toggle switch (START/RUN, OFF, GLOW PLUG) (7) handle in the START/RUN position. After unit
starts, lower and latch control box cover door (3) to prevent restriction of condenser air flow.
i. If the refrigeration unit does not start automatically, manual start the unit per the following.
NOTE
The engine cannot be manually started at temperatures below (40F (4C).
(1) Open left side door (2) and front door (14). Loop a piece of wire, string, or other suitable material around
the fuel shut-off valve (15) shaft that is long enough to reach through the front door.
NOTE
Push switches in the side condenser door frames will prevent the refrigeration unit from
operating if the side doors are open.
(2) The wire/string loop will be used to manually activate the fuel shut-off valve (15) to the operating position
and must be held until the engine is started. Close the left side door (2).
(3) Push the ENGINE FAULT RESET button (5) to the off position (white band visible).
(4) Open the engine guard door (16) and turn the flywheel (17) CCW until you feel resistance indicating you
have reached a compression stroke. If you over turn and feel no resistance, continue to turn until you feel the beginning
of the next compression stroke.
(5) Wrap a pull rope CW onto the flywheel (17).
(6) Pull on the wire/string to activate the fuel shut-off valve (15) to the operating position and hold.
(7) Place the toggle switch START/RUN, OFF, GLOW PLUG (7) handle in the START/RUN position and pull
the rope.
(8) If the engine does not start, place the toggle switch START/RUN, OFF, GLOW PLUG (7) handle in the
OFF position and repeat steps (4) thru (7).
