5. INSTALLATION
The SMARTPACK 40H is designed as an integrated compressor system for connection to an existing hydraulic
system. The SMARTPACK 40H only requires connection of a pressure line in and a return line out (optional: a
motor drain line) connections to the tank line and a method for controlling flow such as solenoid valve and flow
orifice.
WARNING(!) When setting the compressor unit up, ensure there is a safety mechanism in place to
prevent any excessive flow or pressure into the compressor hydraulic circuit. MEA will not warrant any
damage caused and will void warranty due to inadequate safety protection of the existing hydraulic
system.
IMPORTANT: COMPRESSOR MUST ROTATE IN THE COUNTER-CLOCKWISE DIRECTION WHEN
LOOKING AT THE COMPRESSOR SHAFT END.
1. Install SMARTPACK 40H into position on the vehicle using 6 x M12 x 1.75 Grade 8.8 Fasteners and
rubber isolators between the vehicle and compressor. Rubber isolator can be supplied if required (MEA
P/N 7251-P0032).
2. Install the hydraulic lines including any flow control (such as unloader valve), i.e. pressure in, return out,
and drain line to tank.
3. If frameless version is purchased; install the cooler and connect the compressor cooler lines to both the
cooler and the compressor, see Appendix-A, Page 28 for port identification.
4. Connect the electrical harness to the vehicle, see page 17-20;
a. If purchasing the electrical control box; be sure to place an in-line weatherproof fuse (30A –
12V and 15A – 24V) within 300mm of the vehicle battery.
b. If purchasing the basic electrical control (Murphy) ensure the voltage supplied is compatible
with your vehicles voltage rating.
5. Connect the pressure gauge line from the control box to the compressor, black nylon tubing, ensure
when you connect that the tube is inserted correctly.
6. Check the level of oil in the compressor, fill if required to the level indicated in Appendix-A, Page 53.
a. If a remote/frameless version is purchased and the oil cooler is positioned above the
compressor, an in-line non-return valve must be placed at the compressor oil outlet to prevent
oil flowing from the cooler back into the compressor oil outlet, see appendix-A, Page 28 for port
identification.
7. Switch on the vehicle and activate the vehicle flow control (turn PTO on).
8. Turn on the compressor either at the control box or in cab and test the hydraulic solenoid for operation.
9. Turn the unload/load switch to load and check the compressor builds pressure to the regulated pressure
setting.
10. Plug an air tool into the air outlet and operate, checking that the compressor works as required, run for
10mins. Whilst it is running check for oil leaks and air leaks in any of the hosing and nylon tubing.
11. Unload the compressor, switch off the control box, switch off the vehicle and check for any visible
signs of hydraulic fluid leakage. When cool (safe to touch), and switched off, re-check compressor
oil level
