Introduction

The Vent-Axia HR500IP unit is designed for mounting in internal walls for installations
using ducted extraction and fresh air supply. Air movement is achieved by using in-line
duct fans or wall mounted units to suit the length and configuration of ducting systems.

The unit is compatible with Ø300mm flexible duct and is ideally suited for use with in-line
fans and external wall louvres.

Concentric reducers are available to convert inlet and exhaust spigots to 250mm or
200mm diameter for use with alternative sized fans and ducting if required.

Typical Installation

Installation

The HR500IP unit should be set in an inner wall with the grille flange set flush with the
inner surface (a steel lintel is provided for additional support of the building fabric if
required). If used this will automatically produce a 3° slope of the unit away from the inner
grille for drainage of any condensate which may form during operation.

A 22mm drain is situated between inlet and exhaust spigots and should be connected to a
suitable drain/soakaway.

Maintenance & Cleaning

The HR500IP unit requires only occasional cleaning. By depressing the two buttons on either
side of the internal grille, the grille, pre-filters and heat exchanger can be easily removed and
cleaned by using a vacuum cleaner or by washing in luke warm soapy water.

In heavily polluted and smoky enviroments it is recommended that the heat exchanger unit is
examined for cleaning purposes every 3 months.

Spare heat exchanger cells and filters are available to enable immediate change over of soiled
units, which can be cleaned for later use.

The unit is supplied with four, 6-month Timestrip indicators. A Timestrip is a single use self­adhesive label that once activated will turn red over 6 months. It should be used to keep track of
when the filter and cell need cleaning/replacement. Using the self-adhesive backing the strip
can stuck near the units controls, or in a easily visible place.

A normal cleaning schedule for a unit would be as follows:

Note: The above is the minimum requirement; more frequent cleaning intervals may be needed
depending on the environment the unit is installed in.

After installation Activate the 1st Timestrip

After 6 months Clean cell, clean filter, activate 2nd Timestrip

After 12 months Clean cell, clean filter, activate 3rd Timestrip

After 18 months Clean cell, clean filter, activate 4th Timestrip

After 24 months Clean cell, replace filters, the new filters will be supplied with 4

additional Timestrip indicators

Activating the Timestrip.

1. Activation: Fully squeeze the activation button between thumb and finger. A red line will
appear within 1-2 minutes to show that the Timestrip has been activated.

2. Peel off the backing liner and stick the Timestrip to the Unit or near the controls of the unit.
The location should make it obvious to the person responsible for maintenance that the unit
needs attention.

3. Once activated, the red dye will indicate elapsed time by moving through the white window
and past each time marker. The progress of the red dye is irreversible and each Timestrip can
only be used once.
