Safety Information
This appliance can be used by children aged from 8 years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or
instruction concerning use of the appliance in a safe way and understand the hazards involved. Children
shall not play with the appliance. Cleaning and user maintenance shall not be made by children without
supervision.
• Hot water may drip from the discharge pipe of the pressure-relief device, this discharge pipe must be
le open to the atmosphere.
• The pressure-relief device is to be operated regularly to remove lime deposits and to verify that it is
not blocked.
• Drain valves are located on the hot water tank to allow draining of the water from the primary and
secondary.
• This appliance is intended to be permanently connected to the water mains and not connected by
a hose-set.
• A discharge pipe connected to the pressure relief device must be installed in a downwards direction
and in a frost-free environment.
• The Appliance power cable is to be connected to a suitably sized isolator which disconnects all poles
with a contact gap of at least 3mm.

a separate non-self-resetting thermostat and 2 port valve must be installed in the primary circuit.

3Modul-AIR Exhaust Air Heat Pump Installation Guide
Preface
Dear installer,
You are about to install a Joule Modul-AIR exhaust air heat pump. This system shall only be commissioned
by a qualified installer. You the installer must have been trained by Joule. Systems installed by untrained
installers will have no warranty guarantee. Systems are to be commissioned using the Joule commissioning
App.
Before you start installing the Joule Modul-AIR, please ensure that you have fully read and understood this
installation manual. Use the table of contents on the next page to quickly find information.
Prior to the installation of the Modul-AIR system the dwelling must be visited and inspected by Joule to
determine whether the Modul-AIR is suitable for your specific job. This inspection is also carried out
to determine which configuration of Modul-AIR system is the most appropriate to install in your specific
scenario.
To successfully install the Green Comfort, it must be installed in combination with the Joule Modul-AIR.
The warranty terms are 2 years parts and labour on the Modul-AIR heat pump, Green Comfort module and
all heat pump system accessories supplied by Joule, with 25 years warranty on the Modul-AIR cylinder body.
To maintain these warranty guarantees a once yearly service must be carried out by a competent engineer.
For further details on the terms and conditions please consult the warranty section of this manual.
Based on the experience of the installers we want to further improve the Modul-AIR and Green Comfort.
Your feedback on the product, installation and this manual is appreciated
The Modul-AIR and Green Comfort complies with European directives and additional national regulations
which are indicated in a CE marking. The corresponding declaration of conformity can be requested from
Joule.

Introduction
General Product Description:
Who is this manual for?
Intended & unintended use
Nameplate and symbols on the product
The Type Plate
The Modul-AIR extracts heat from the stale indoor air that is to be exhausted outdoors. This heat, rather then
being lost to the atmosphere as in traditional ventilation system, is rather returned to the central heating
system allowing to fully electrically heat a hot water tank and, depending on the variant, this recaptured
energy is also used for the space heating of the house.
All variants that provide space heating are available with or without balanced ventilation (Green Comfort
Module).
This manual details two different variants of Modul-AIR:
• Modul-AIR Aqua: Heat Pump Water Heater & Joule hot water storage tank
• Modul-AIR AII-E: All Electric Space Heating, water Heating & Joule hot water storage tank
This manual is intended for the professional installer. The installer must be certified by Joule and have
successfully completed the Modul-AIR training. The installer does not need to be in possession of a STEK or
F-gas certification.
The purpose of the manual is to support you in installing the Modul-AIR with or without the Green Comfort
unit safely and correctly.
The Modul-AIR may only be used to use the heat from ventilation air to heat a home and optionally to heat
tap water. The Modul-AIR should only be installed according to the instructions in this manual.
Any other use is considered unintended use and may result in damage to the Modul-AIR and/or personal
injury. Always follow the instructions in the accompanying manual(s) and if in doubt contact the manufacturer.
The Green Comfort is only used in combination with the Modul-AIR to provide a home with balanced
ventilation. The Green Comfort may only be installed according to the instructions in this manual.
Any other use is considered unintended use and can lead to damage to the Green Comfort and/or personal
injury. Always follow the instructions in the accompanying manual(s) and if in doubt, contact Joule
Important information about your unit can be found on a rating plate as well as other symbols located on
the product.
The Type Plate provides information about the unit. The Type Plate is located in two places on and in the
Modul-AIR and Green Comfort units as shown:

13Modul-AIR Exhaust Air Heat Pump Installation Guide
Modul-AIR Variants
Depending on the situation the Modul-AIR can be used in five different variants. This manual is particular
to 2 variants: the All-E and Aqua. Detailed Mechanical and Electrical schematics specific for these can be
found in the Appendices of this installation manual.
The Modul-AIR All-E can heat a house fully electrically and provide hot water via a Joule hot water storage
tank. This variant contains both an integrated electric flow heater and a three-way valve.
The Modul-AIR Aqua is variant for domestic hot water generation in applications where central heating is
already provided for by some other source, e.g electric radiators. The Modul-AIR supplied along with the
immersion in the Joule hot water storage tank can provide fully electric heating to domestic hot water for
your taps and showers.
