5. Do not exceed the recommended distance and lift from the base unit to the heat dump of 9M
Lift, 40M Run.
6. 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.
7.
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 40
o
C
8. Do not kink the flow and return tubes which would restrict the coolant flow.
9. Do not insulate the flow and return lines.
10. The flow and return lines must not be strapped together, as heat transfer between the two will
effect the system performance.
11. 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.
12. 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)
GLYCOL MODULE INSTALLATION INSTRUCTIONS
1. Site the glycol pump module within 2 meters of the base unit and using suitable wall fixings,
secure the module to a wall.
2. Connect the glycol module’s power supply to the 240V power outlet socket on the base unit.
(DO NOT SWITCH ON YET)
3. Using Cobracol tubing, connect the ‘COOLANT FLOW’ from the glycol module to the
‘COOLANT IN’ on the base unit.
4. Again using Cobracol tubing connect the ‘COOLANT OUT’ from the base unit to the ‘FLOW’ on
the first heat dump. Connect the ‘RETURN’ on heat dump to the ‘FLOW’ on the second heat
dump. Connect the ‘RETURN’ of the second heat dump to the ‘COOLANT RETURN’ on the
glycol module to complete the circuit.
5. Finally, connect the 1.5mm twin wire coming from the heat dumps to the 24v outlet sockets on
the glycol module using the two pin plug supplied with the glycol module. It does not matter
which way the wires are connected as they are not polarised.
6. Ensure the lines are correct and secured neatly and free from kinks.
7. Fill the glycol module reservoir tank with a quantity of coolant mixed 30% glycol to 70%
water, ensuring a quantity remains for topping up the system when priming.
The following table should be used as a guideline for the volume of coolant for varying
installations.

8. Upon switching the unit on, the pump in the glycol module will start together with the heat dump
fans.
As the system primes, the level will drop in the coolant header tank. Keep topping
this up until the system is full, there are no air locks and that coolant is returning freely into
the header tank. If the system trips out on the pressure switch whilst priming, this will have to
be reset before the system can start again.
