02. Please ensure there is adequate space for installation and maintenance.
It is recommended a head height of 300mm is required.
03. The Air
with less than 0.5mtr duct length.
04. The product is to be installed in a dry and free from humidity location.
05. Su
Please refer to the technical data sheet for the products weight.
06. Please select a suitable location for the exhaust air vent to the outside.
Always insulate the exhaust air ducting to avoid condensation when operational.
07. Please select a suitable location for the supply air intake ducting from the outside if being used
on high performance air tight building. Always insulate the supply air intake ducting to avoid
condensation when operational.
08. Please ensure there is access to the front panel for maintenance.
Please note the clearance areas required for maintenance.
09. Always allow extra room for pipe connections and power cables.
10. Always refrain from installing on a surface with loose coverings as the product
may make a vibrating noise when operating.
If the product is installed in a location where there is a possibility of frost, then all precautions
NOTE
The following locations are not recommended as suitable installation locations of the product.
Areas containing toxic gases or mineral oils.
II. TRANSPORTING THE PRODUCT
01. This exhaust air heat pump is heavy and requires at least two people
to lift it with the assistance of lifting equipment.
02. It is always recommended to lift the product with all its packaging
in place.
03. Always wear PPE when lifting the product.
04. Avoid lifting at the angle greater than 75°.

III. THE INSTALLATION OF HEAT PUMP
01. Always leave enough space for installation and maintenance. The below illustrations are guidelines only.
02. The air inlet ducting is vented from “wetrooms” like a kitchen, bathroom, ensuites and utility rooms. The minimum
size ducting is 150mm rigid or approved semi rigid ducting. Flexible ducting is not recommended and should
not be used.

06. The correct cold water intake pressure is between 1.5BAR and 6.5BAR. If the pressure is less than 1.5BAR a pressure
pump may be required for operation. Installing a pressure gauge inline with the cold water inlet will assist the user if
there are pressure issues after the installation.
07. During operation and heat pump cycle, there will be condensation droplets within the heat pump. Always ensure
the condensate pipe is connected to the drainage network.
NOTE
The safety relief valve needs to be pulled every six
months to ensure it works correctly and is not blocked.
Do not hold down the handle of the safety valve.
Do not block the drain.
If this product is installed in an outbuilding or
unheated space, please ensure all pipework including
ducting is insulated well. Failure to do so could result
infrozen pipework and condensation issues.
NOTE
WARNING
Insulate the drainage pipe to avoid freezing in cold
weather..

IV. DUCTING INSTALLATION INSTRUCTIONS
Option 1 is recommended at all times. Only use
semi-rigid ducting when 150mm solid ducting is not
viable to use.
When the air intake ducting pass through the
unheated section of the building it is essential that the
ducting is wrapped in foil back insulation.
The exhaust air ducting must be wrapped in continuous
foil backed insulation and care must be taken when
the ducting leaves the building and vapour control layer.
Sample ducting layout. Shows a power open, spring
close damper on the supply air ducting. This is
possible to achieve by conecting the damper cable
from the H2O unit.
ELECTRICAL CONNECTIONS
THE ELECTRICAL CONNECTIONS MUST BE COMPLETED BY A QUALIFIED AND TRAINED PROFESSIONAL.
This product must be wired on a separate circuit protected by a 20A RCD/MCB (RCBO)
The circuit must be connected to a reliable earth electrode connected to the consumer unit.
