### Temperature Adjustment Procedure

Start by removing the handle and trim to access the cap assembly on your **K-304 Rite-Temp valve**.

Next, take off the black o-ring and caution tag to expose the **valve stem**.

Turn the valve stem clockwise to increase the **maximum hot water temperature**. Keep it below 120°F to avoid **scalding**.

After setting the desired temperature, test the water to confirm accuracy.

Once satisfied, replace the red or black collar on the valve stem to maintain proper function.

Finally, reassemble the valve by reinstalling the caution tag, o-ring, trim, and handle securely.

This precise **temperature adjustment procedure** guarantees your Kohler valve operates safely and efficiently, providing reliable control over your shower’s water temperature.

### Safety Precautions and Tips

Adjusting the temperature on your Kohler Rite-Temp valve requires careful attention to safety. First, always **turn off the water supply** before starting any adjustment to avoid accidental scalding or water damage.

Use caution when handling valve components; sharp edges may cause injury, so wear protective gloves if needed. Keep the **maximum water temperature** set to 120 degrees F to guarantee shower safety and prevent burns.

After making adjustments, **securely fasten all valve parts** and retest the water temperature to confirm accuracy.

Finally, thoroughly read and **follow the manufacturer’s instructions** and safety tags attached to the valve assembly.

Adhering to these safety precautions guarantees a safe, effective temperature adjustment for your Kohler shower valve.

## Reassembling Your Kohler Valve After Adjustment

After you’ve adjusted the temperature, go ahead and reinstall the **o-ring** and caution tag. This helps make sure everything seals properly and keeps things safe.

Next, secure the trim and handle firmly so they look good and work well.

Before you turn the water supply back on, take a moment to **double-check** that all the parts are tight and lined up correctly.

### Reinstalling Valve Components

Reinstall the **valve components** carefully to guarantee your Kohler shower valve functions correctly after temperature adjustment.

Start by placing the **black o-ring** back onto the valve to maintain a proper seal and prevent leaks.

Reattach the **caution tag** to indicate the new temperature setting.

Secure the trim firmly to the wall, ensuring all components align for a tight fit.

Finally, reinstall the handle on the valve, positioning it for **smooth operation**.

Double-check all valves and trim components are tight and functioning before use.

### Securing Trim And Handle

Securing the trim and handle assures your **Kohler valve assembly** operates reliably and maintains a **watertight seal**.

After adjusting the valve temperature, follow these steps carefully to complete the reassembly:

1. Place the black o-ring back on the valve assembly to assure a proper seal and prevent leaks.
2. Reattach the trim to the wall, aligning it precisely for a seamless and professional finish.
3. Reinstall the handle, verifying it turns smoothly without obstruction, and secure the caution tag to provide safety information.

### Ensuring Proper Assembly

Once you’ve secured the trim and handle, focus on reassembling your Kohler valve to confirm reliable operation.

## Fixing Hot Water Coming On First in Your Valve

If hot water comes on before **cold** in your Rite-Temp valve, it usually means the water **mixing order** is incorrect due to installation.

> Hot water activating before cold in your Rite-Temp valve often indicates incorrect water mixing order during installation.

Fixing **hot water activation** first in shower valves involves checking the **mixer cap assembly**. Follow these steps:

1. Turn off the water supply to the valve for safety.
2. Remove the screws from both sides of the black cap to access the red and black tabs.
3. Confirm the red tab is positioned at 12:00 (upwards). A downward position (5:00) reverses flow, causing hot water to come on first.

After **repositioning the tabs**, reassemble the cap, restore water supply, and test the valve.

Correct alignment confirms proper hot and cold water mixing, resolving the issue efficiently.

## Safety Tips for Maintaining Kohler Valve Temperatures

Because adjusting your Kohler valve’s temperature involves direct contact with hot water systems, you should always turn off the water supply before making changes. This helps prevent accidental scalding.

Set the maximum hot water temperature to no more than 120°F for safety. Handle valve components gently to avoid damage, especially the trim and collar.

After adjustments, reattach the caution tag to remind users of temperature risks. Regularly test the water temperature to guarantee safe operation and detect anomalies.

| Safety Tip | Action |
| --- | --- |
| Water Supply | Turn off before adjustment |
| Max Temperature Setting | Do not exceed 120°F |
| Post-Adjustment Check | Test water temperature regularly |
