Mechanical Ventilation with Heat Recovery 

Installation and Maintenance 

1.0 Introduction 

IMPORTANT: Unit must not be switched off during normal 

operation, the product is designed to run continuously. 

HR01-Loft is designed to provide mechanical supply and 

extract ventilation with heat recovery. (Code: HR01L). 

The units are fitted with two independent fans. Each fan has 

full speed control for background and boost ventilation rates 

as well as a run-on timer facility. To recover heat from the 

extract air the heat exchanger block is utilised. This heat 

exchanger can recover up to 95% of the normally wasted heat.

2.0 Installation 

Installation must be carried out by competent personnel in 

accordance with the appropriate authority and conforming 

to all statutory governing regulations. 

All mains wiring must be in accordance with the current I.E.E. 

Regulations, or the appropriate standards. Ensure that the 

mains supply (Voltage, Frequency and Phase) complies with 

the rating label. 

Please note a clear working space is required around the 

installed unit to allow the cover to be removed and provide 

sufficient access for maintenance such as filter change. 

The fan must be installed indoors, away from direct sources of 

frost, heat, water spray or moisture generation. 

The unit is designed for mounting on the roof joists in the 

loft space using four “L shape” metal brackets and four A.V. 

mounts supplied with the unit. Please note that various 

positions for the brackets are available to suit different joist 

centres. 

Connect the four ‘L’ shape fixing brackets to the unit with the 

M4 screws (provided) they can be attached to the long, or 

short sides of the unit depending on requirements. Lower the 

unit with the “L” shape fixing brackets attached onto the joists 

(see figures 2a and 2c). Mark through the brackets and drill 

four clearance holes into the top surface of joists. 

Locate anti-vibration mounts (supplied) above and below each 

bracket fixing point hole and, using 4 suitable screws (not 

provided) and washers, fix the unit to the joists (see fig 2b). 

Do not overtighten the fixings. The distance from the top 

washer on the A.V. mount to the joist when installed must 

not be less than 30mm.

5.0 Data cable installation 

A 4-core data cable is used to connect devices. Do not run 

data cable in the same conduit as the mains cables and 

ensure there is a 50mm separation between the data cable 

and other cables. The maximum cable run between any two 

devices is 300m when it is installed in accordance with the 

instructions. Please note that the total data cable length used 

in any system must be less than 1000m. Keep the number of 

cable joints to a minimum to ensure the best data transmission 


6.0 Adjusting the HR01-PIR run on 

timer (1-60 minutes) 

Assuming the sensor(s) are installed, adjustment of the set 

points achieved by tilting the sensor forwards which exposes 

the adjustment aperture (see fig 5). Using a small screwdriver, 

gently turn the dial either clockwise or anti-clockwise to 

increase or decrease the set point. When adjustments are 

made to the sensor, the LED light on the sensor front will flash 

on and off to show the set point. First, green flashes will 

indicate the set point in TENS, then red flashes will indicate 

UNITS. For example one green flash and five red flashes show 

you that the PIR timer is set to fifteen minutes. 

7.0 Detection range 

Up to 10m directly in front of lens and up to 2m at 40 o to the 

lens axis. 


8.0 Maintenance 

The unit does not require any maintenance. However, for 

optimum performance, it is advisable to remove any 

accumulated dust with a low power vacuum cleaner. 

NOTE: Installation and Maintenance of the equipment must 

be as directed in the instructions provided with the unit.
