5. INSTALLATION
The SMAC90H is designed as an integrated compressor system for connection to an existing hydraulic
system. SMAC90H only requires connection of a pressure line in, a return line out and a connection of
the motor drain line (if applicable) to the tank.
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.
1. Install SMAC90H into position on the vehicle using 4 x min. M12 x 1.75 Grade 8.8 Fasteners.
2. Install the hydraulic lines, i.e. pressure in, return out and drain line.
3. If purchased the Frameless version only; install the cooler and connect the compressor cooler lines to
both the cooler and the compressor, see APPENDIX A, Page 39.
4. Connect the electrical control box to the vehicle; be sure to place an in-line weatherproof fuse
(30A – 12V and 20A – 24V) within 300mm of the vehicle battery. Ensure the control box is
compatible with your vehicle’s voltage rating.
5. Connect the pressure gauge line to the SMAC90H, see circuit diagram (Page 21)
6. Connect the terminals of the electrical loom as per the circuit diagram relevant to your vehicle
to both the vehicle and the SMAC90H.
7. Check the level of oil in the compressor.
8. Switch on the vehicle, turn on the compressor at the control box 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 a min. 10mins.
11. Unload the compressor, switch off the control box, switch off the vehicle and check for any
visible signs of hydraulic fluid leakage.
12. When cool (safe to touch), and switched off, re-check compressor oil level
