Need help?Do you have a question about the HiB 33100 and is the answer not in the manual?
This document provides a comprehensive guide for the installation, operation, and maintenance of HiB Hush & Breeze wall-mounted bathroom fans. These fans are designed to enhance bathroom ventilation and are available in various finishes and with different control options.
The HiB Hush and Breeze fans are designed to extract humid air from bathrooms, helping to prevent the build-up of moisture, mold, and mildew. They are wall-mounted or ceiling-mounted units that connect to the domestic electrical mains supply. Both models offer options for basic timer control or advanced timer and humidity sensor control, allowing for automated operation based on environmental conditions.
Both Hush and Breeze products are suitable for installation in Zone 2 and Outside Zones of a bathroom, as defined by IEE wiring regulations. It is crucial to follow the provided zonal diagram (Fig 1 on page 4) to ensure safe installation. All electrical installations must comply with current IEE wiring regulations and relevant building regulations, and HiB recommends that all electrical bathroom products be fitted by a suitably qualified, Part P registered electrician.
The fans are designed to be connected to an on/off switch outside the bathroom or to a ceiling-mounted pull cord switch. Before drilling, it is essential to ensure there are no hidden cables or pipes in the wall.
These models activate when a control voltage is supplied to the LT terminal. Once the voltage is switched off, the fan continues to operate for a set time period (T), which is adjustable between 2 and 30 minutes. The run time is regulated by turning a potentiometer clockwise to increase and anticlockwise to decrease the duration.
These advanced models operate when a control voltage is applied to the LT terminal OR when the humidity level in the bathroom exceeds a pre-set threshold. The humidity threshold is adjustable via a potentiometer (H). Setting H to its lowest (60%) will cause the fan to run most of the time, while setting it to the highest (90%) will make the fan operate only at higher humidity levels. Once the humidity has been reduced to the required setting, the fan will continue to run for the duration set by the timer potentiometer (T). Both the timer (T) and humidity (H) values are regulated by turning their respective potentiometers clockwise to increase and anticlockwise to decrease the running-out time and humidity level. To set the maximum humidity level, the potentiometer H should be set to the H max (90%) position. A plastic screwdriver is provided for adjusting these settings to prevent damage to the control unit.
For ceiling mounting, follow the wall mounting procedure, but ensure ducting is not mounted vertically to the outside. This prevents moisture from returning to the motor.
Fan maintenance should only be performed after the fan is disconnected from the mains power supply. Maintenance primarily involves periodic cleaning of the fan surfaces to remove dust and dirt.
The product must not be mixed with general household waste, indicating it should be disposed of responsibly in accordance with WEEE regulations.
In the unlikely event of product failure, customers should contact HiB customer services using the provided contact details.
