The Drayton TRV4 valve head is designed for straightforward replacement of existing thermostatic radiator valve heads. Ensure your heating system is off and cooled down before beginning installation.

  1. Before removing the old head or installing the new one, twist the temperature setting of the TRV4 head to its highest setting (typically '5' or 'MAX'). This retracts the internal mechanism, preventing damage to the valve's pin during installation.
  2. Carefully unscrew the chrome collar at the base of the old thermostatic valve head to remove it from the radiator valve body.
  3. Align the new Drayton TRV4 head with the valve body. Ensure the internal pin of the valve body is not obstructed.
  4. Screw the chrome collar of the new TRV4 head onto the valve body until it is hand-tight. Do not overtighten.
  5. Once installed, you can adjust the temperature setting to your desired level.

The Drayton TRV4 allows you to control the temperature of individual rooms by regulating the hot water flow to the radiator. The head features numbered settings for precise temperature control.

  • Atunṣe iwọn otutu: Rotate the head to align the desired number with the indicator mark. Higher numbers correspond to warmer temperatures. The valve has a tactile detent function for each setting, allowing you to feel the position without looking.
  • Idaabobo otutu: Some models may include a snowflake or asterisk symbol (*), which typically represents a frost protection setting. When set to this position, the valve will open if the room temperature drops to approximately 5-7°C, preventing pipes from freezing.
  • Lilo Agbara: To maximize energy efficiency, set the TRV4 to a comfortable temperature for each room and avoid overheating. Close doors to rooms with lower temperature settings to prevent heat loss from warmer areas.

Regular maintenance ensures the longevity and optimal performance of your TRV4 valve head.

  • Ninu: Wipe the valve head with a soft, damp asọ. Yago fun abrasive ose tabi olomi ti o le ba awọn ipari.
  • Gland Seal Inspection: Periodically inspect the gland seal of the radiator valve body (the part the TRV head screws onto). If the TRV head fails due to plastic degradation, it is often caused by central heating water seeping past a worn gland seal. It is highly recommended to replace the gland seal when replacing the TRV head, and to inspect it annually.
  • Ṣayẹwo akoko: Before the heating season begins, ensure all TRV heads move freely through their full range of settings. If a head feels stiff, gently rotate it back and forth a few times to free the internal mechanism.
