Heat Dump General Guidelines
•
It is important that the heat dump is sited correctly to enable it to work
efficiently. The guidelines below should be adhered to wherever
possible.
•
Ensure the unit is sited on an outside wall (preferably non-south facing)
in the correct orientation out of direct sunlight.
•
Ensure there are no other heat sources, i.e. a condensing unit or
another heat dump, in the immediate vicinity, where hot air may be re-
circulating.
•
Use the recommended tubing (15mm O/D, 10mm I/D Special EVA) to
connect the base unit to the heat dump. Do not use PVC braided tube,
as this is not compatible with glycol and will degrade over a period of
time.
•
Do not exceed the recommended distance and lift from the base unit to
the heat dump of 10 m lift / 50 m run.
•
The heat dump must be connected using a minimum of 1.5mm two
core cable. If a smaller cable is used, a voltage drop will occur which
may cause the fan motor to run at a reduced speed.
•
If the unit is to be installed inside a building or room, ensure that there
is adequate ventilation within the room to enable the heat to be
dissipated effectively. Temperatures within the room should not exceed
32°C.
•
Do not kink the flow and return tubes, which would restrict the coolant
flow.
•
Do not insulate the flow and return lines.
•
The flow and return lines must not be strapped together, as heat
transfer between the two will affect the system performance.
•
Ensure that the heat exchanger matrix of the heat dump is kept clean
and free from obstructions. It is recommended that it should be cleaned
with a soft brush at regular intervals (see maintenance schedule).
•
To enable the heat dump to be mounted on a flat surface, a floor
standing mounting kit is available as an option. (Order part number 09-
0203-01)
For details on use and mounting of the heat dump, refer to installation
instructions on page 24.
