HEAT DUMP AND GLYCOL MODULE INSTALLATION - WATER COOLED UNITS

HEAT DUMP - GENERAL GUIDELINES

1. 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.

2. Ensure the unit is sited on an outside wall (preferably non south facing) in the correct orientation

out of direct sunlight.

3. 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.

4. 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.

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.

NOTE: Maximum Lift = 9M Maximum Run = 40M

40 METERS 5.4 LITRES 10.6 LITRES

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.

WARNING

All water cooled units are fitted with a MANUAL RESET pressure switch to protect the system.

If a fault occurs it is likely to be one of the following:-

1. Low water \ glycol level , Coolant leak, Blockage within cooling system .

2. Component failure:- Heat dump fan motor, Water pump, 24v Transformer, wiring fault.

If the fault persists, it should be rectified before further operation.

HEAT DUMP INSTALLATION INSTRUCTIONS

NOTE: The unit should be installed and serviced by a suitably trained person.

Unpack the unit from its transportation packaging and visually inspect for signs of damage.Site the
dump in a convenient location, preferably in a non-heat sensitive and shaded areaon the outside of
the building. If it cannot be installed outside, ensure that the area is free from other heat sources and
is adequately ventilated to prevent heat build up from the hot exhaust air from the heat dump.
In either situation the heat dump should be sited to allow free circulation of air.
The maximum recommended height of the heat dump above the cooler is 10 meters.

Fitting

Remove the wall mounting bracket from the assembly, (mounted on lift off hinges).
Slacken the two fixing screws securing the cover/fan assembly to the condenser matrix ,
swing the cover open and lift off the assembly.

With reference to the attached drawing drill the surface onto which the heat dump is to be fitted at
the stated mounting hole centers ensuring that adequate clearance is allowed around the heat dump
to allow future access for cleaning.

Note - the wall mounting bracket can be used as a guide for marking its hole centers . Ensure that
the wall mounting bracket is mounted squarely to ensure level movement of the condenser matrix
when fitted.

Either mark the position of the third mounting screw at the time of marking the wall mounting bracket
position, or after fitting the wall mounting bracket hang the condenser matrix on, close against the
mounting surface and mark the fixing position.

Note - the third fixing screw will pass through the hole in the condenser matrix. The retaining clamp
is fitted over the screw which can then be tightened to retain the condenser matrix.

Connect the flow and return pipework from the glycol module and base unit to the fittings on the heat
dump labeled “FLOW” and “RETURN” and secure the pipes to the mounting surface so that the
weight of the pipes is not being carried on the heat dump fittings.
Note - Do not kink the pipework as this will restrict coolant flow.

Do not insulate the pipework. (Pipework mounted on an exterior surface may be insulated if
it is felt that due to extreme conditions freezing may occur).
Do not strap the flow and return pipes together as heat transfer between the two will effect
the systems performance.

Route a twin core 24 volt supply cable (1.5mm csa) through the lower guide tube and then through
the strain relief grommet positioned below the two way terminal block on the condenser matrix.

Note - The wires are not polarised and may be fitted either way round.

Ensure that the amount of cable entering through the main cover is not excessive and cannot
become entangled in the fan blade. Tighten the strain relief grommet to support the cable . This
should not be the only means of support for the cable, therefore fix back to the mounting surface at
regular intervals along the cable length.

6

After the condenser matrix is fully fitted to the mounting surface, hang the cover/fan assembly onto
its hinges.
With the cover/fan assembly open, connect the wires from the fan to the terminal block .
Note - Ensure that the wiring from the fan is routed through the plastic clip provided to prevent the
possibility of the wires becoming entangled in the fan blade.

Connect the wiring and the Pipework to the cooler following the instructions supplied with the cooler.

Recommended materials for heat dump to cooler connections.

Pipework - 15mm OD x 10mm ID COBRACOL tubing.
