Introduction
This instruction manual provides essential information for the installation, operation, maintenance, and troubleshooting of your GROHE 37078PI0 Servo-set. This product is designed for use in toilet cisterns, featuring a float valve for water level control and a flush valve with an interruptible mechanism for efficient flushing.
Please read this manual thoroughly before proceeding with installation or use to ensure proper function and longevity of the product.
Product Overview
Figure 1: GROHE 37078PI0 Servo-set components. The image displays the two primary components: a float valve on the left, responsible for controlling the water level in the cistern, and a flush valve on the right, which manages the water release for flushing.
The GROHE 37078PI0 Servo-set includes the necessary components for regulating water intake and flushing in a toilet cistern. It features:
- Float Valve: Controls the water filling process and maintains the desired water level within the cistern.
- Flush Valve: Facilitates the release of water for flushing, incorporating an interruptible mechanism for water conservation.
- Fittings and Stopper Cap: Essential accessories for secure installation and operation.
Setup and Installation
Installation of the GROHE 37078PI0 Servo-set requires basic plumbing knowledge. It is recommended to consult a qualified plumber if you are unsure about any steps. A detailed installation guide is included with the product.
- Preparation: Turn off the main water supply to the toilet and flush the toilet to empty the cistern. Remove the cistern lid.
- Remove Old Components: Carefully disconnect and remove the existing float valve and flush valve from the cistern. Clean any residue from the cistern base.
- Install Flush Valve: Position the new GROHE flush valve in the cistern's flush opening. Secure it from underneath the cistern using the provided fittings and stopper cap, ensuring a watertight seal.
- Install Float Valve: Mount the new GROHE float valve in the designated inlet hole within the cistern. Connect it to the water supply line, ensuring all connections are tight to prevent leaks.
- Adjust Water Level: Once installed, turn on the water supply. Allow the cistern to fill. Adjust the float mechanism on the float valve to set the desired water level, typically indicated by a fill line inside the cistern or just below the overflow pipe.
- Test Functionality: Flush the toilet several times to check for proper operation of both the flush and float valves, and to ensure there are no leaks.
Refer to the specific diagrams and instructions in the included Installation Guide for precise steps tailored to your product.
Operating Instructions
The GROHE 37078PI0 Servo-set is designed for straightforward operation and water efficiency.
- Flushing: To flush the toilet, press the flush button or lever. The flush valve will open, releasing water from the cistern into the toilet bowl.
- Interruptible Flush: This servo-set features an interruptible mechanism. If you wish to stop the flush prematurely (e.g., for liquid waste), simply press the flush button or lever a second time. This will close the flush valve, conserving water.
- Water Refill: After flushing, the float valve automatically opens to refill the cistern. Once the water reaches the pre-set level, the float valve closes, stopping the water flow.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your GROHE Servo-set.
- Cleaning: Periodically inspect the float valve and flush valve for mineral deposits or debris. Turn off the water supply, empty the cistern, and gently clean components with a soft brush and mild, non-abrasive cleaner. Rinse thoroughly.
- Seal Inspection: Check the rubber seals on both the float valve and flush valve for wear, cracks, or deterioration. Worn seals can lead to leaks. Replace seals as necessary using genuine GROHE replacement parts.
- Water Level Adjustment: If the water level in the cistern changes or is incorrect, adjust the float mechanism on the float valve to achieve the desired fill level.
- Leak Checks: Regularly check for any signs of water leakage inside or outside the cistern. Address leaks promptly to prevent water waste and potential damage.
