DC House 12V Hydraulic Power Unit Instruction Manual
Model: L12t1217YYDLDY8-1
Introduction
This manual provides essential information for the safe and efficient operation, installation, and maintenance of your DC House 12V Hydraulic Power Unit. This unit is designed to serve as a power source for lifting and pushing devices, commonly used in applications such as dump trailers, garden tractors, forklifts, stackers, and small to medium-sized lifting platforms.
The hydraulic pump is equipped with a 12V DC motor (rated at 1.6KW) and an 8-quart (8-liter) metal oil tank. It is a double-acting unit, meaning it provides power in both directions (up and down) when used with a compatible double-acting cylinder. The maximum pressure at the outlet can reach 3200 PSI (22 MPa), capable of lifting significant loads.
Safety Information
Always observe safety precautions when working with hydraulic systems. Failure to do so can result in serious injury or equipment damage.
- Ensure all electrical connections are secure and correctly polarized (12V DC).
- Disconnect power before performing any maintenance or installation.
- Wear appropriate personal protective equipment (PPE), including eye protection and gloves.
- Do not exceed the maximum operating pressure of 3200 PSI.
- Ensure the hydraulic system is properly bled of air after installation.
- Use only hydraulic oil with a viscosity range of 22-46 mm²/s.
- Keep hands and clothing clear of moving parts.

Setup and Installation
Proper installation is crucial for the performance and longevity of your hydraulic power unit. Follow these steps carefully.
Mounting the Unit:
The hydraulic power unit must be installed horizontally to ensure proper operation and prevent damage. Avoid vertical mounting.
Figure 4: Illustration demonstrating correct horizontal installation and incorrect vertical installation.
Connecting Hydraulic Lines:
- Identify the A1 and A2 ports on the hydraulic power unit. These correspond to the outlet and return ports for double-acting operation.
- Connect clean hydraulic tubing (not included) from the power unit's ports to your double-acting hydraulic cylinder. Ensure your cylinder also has two ports to work with this double-acting unit.
- Secure all connections to prevent leaks.
Electrical Connections:
- Connect the 12V DC power supply (not included) to the motor and the electromagnetic valve according to their marked characteristics (positive and negative terminals).
- Ensure all electrical connections are tight and insulated to prevent short circuits.
Initial Test Run:
After connecting, perform an initial test run without load:
- Briefly start the electric motor. Observe for any abnormal phenomena such as unusual noises or vibrations.
- Check whether all parts run smoothly.
- If everything appears normal, proceed to load testing step by step to ensure smooth operation under working conditions.
Operating Instructions
The DC House Hydraulic Power Unit is designed for straightforward operation using the included remote control.
Double-Acting Operation Principle:
This unit is double-acting, meaning it controls both the extension (UP) and retraction (DOWN) of a hydraulic cylinder. The hydraulic pump will have an outlet and return port for both directions of movement.
- For UP (Extension): Port A2 acts as the outlet, and Port A1 acts as the return.
- For DOWN (Retraction): Port A2 acts as the return, and Port A1 acts as the outlet.

Using the Remote Control:
The included wired remote control allows for simple and precise control of the hydraulic unit.
Figure 6: Visual guide for operating the hydraulic unit with the remote control.
- To Raise (UP): Press and hold the "UP" button on the remote control. The hydraulic cylinder will extend, lifting the load.
- To Stop/Hover: Release the "UP" or "DOWN" button. The hydraulic cylinder will stop at its current position.
- To Lower (DOWN): Press and hold the "DN" button on the remote control. The hydraulic cylinder will retract, lowering the load.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your hydraulic power unit.
Hydraulic Fluid:
- Check Fluid Level: Periodically check the hydraulic fluid level in the reservoir. Ensure it is within the recommended range.
- Fluid Replacement: Replace hydraulic fluid according to the manufacturer's recommendations or if it appears contaminated. Use only hydraulic oil with a viscosity range of 22-46 mm²/s.
- Cleanliness: Keep the hydraulic fluid clean and free from debris. Contaminated fluid can damage internal components.
General Inspection:
- Check for Leaks: Regularly inspect all hydraulic lines, fittings, and seals for any signs of leaks. Address leaks immediately.
- Electrical Connections: Verify that all electrical connections are secure and free from corrosion.
- Mounting: Ensure the unit remains securely mounted and that mounting hardware is tight.
- Cleanliness: Keep the exterior of the unit clean to prevent dirt and debris from entering the system.
