General Description
The SRC14 accurately controls the temperature of
a cooling liquid between -20 to +30ºC. The cooled
liquid is then circulated to an external device via the
inlet and outlet nozzle. The SRC14 has a capacity of
14 litres.
Safety Advice Before Use
• Beware some cooling mediums are ignitable
above ambient temperatures, do not use with
hazardous materials or liquids.
• Never move or carry the unit when in use or
connected to the mains electricity supply.
• Please take care not to touch the cooling
elements under the air filter, as these can be
sharp.
• Do not place anything on top of the unit
during operation
Installation
Position your recirculating cooler on a firm level
surface. A byproduct of the air cooled refrigeration
unit is heat, unnecessary heat build up can lower
the cooling performance of the unit. To avoid
this please ensure the unit is located in a well
ventilated area. The unit should not be exposed
to direct sunlight, humidity, dust or vibration. For
optimum performance the following clearance
should be allowed: 20cm from both sides, 60cm
above the unit and 40cm behind. Do not obstruct
the front ventilation on either unit.
Care should be taken not to tilt the SRC14 by
more than 45 degrees when moving. Ensure that
the castors on the SRC14 are locked prior to use
(only the front 2 castors have stoppers).
Operation
Connection of hoses:
Connect the 90º elbows to the nozzles then
connect the elbow adapters including flow control
valve (Fig. 2) Connect suitable tubing (ID 9mm) to
each nozzle (inlet and outlet)
NOTE: Take care not to use excessive force
connecting the hoses, use universal clips or similar
to secure the tubing if necessary. Always consider
the temperature and pressure requirements before
selecting your tubing material. Use tubing of the
minimum length required, excessively long tubing
will reduce the efficiency of the unit.
Filling procedure:
When choosing your cooling medium you should
take care that there is no risk of corrosion of internal
parts, these include the following materials; copper,
stainless steel, brass, PTFE, polyacetal resin, silicone
rubber, polypropylene oxide and ethylene propylene
rubber. Distilled water should also be avoided as it
could dissolve metal substances in the circulation
line. For operation below +7ºC it is recommended
that ethylene glycol is used as your cooling medium.
Prior to filling the unit make sure that the drain
stopper is in place. Pour 14 litres of your cooling
medium into the circulation tank, or until the liquid
level is approximately 2 cm from the top of the tank,
take care not to overfill. Replace the circulation tank
cover.
Operation
Connect the power lead to the IEC connector at the
back of the unit. Make sure that the power switch
and pump switch are in the off position on the
control panel (Fig. 3) then connect the power cable
to the mains supply. Turn the power switch on the
main control panel to the on position. The display
will show the current temperature of the cooling
medium. The refrigeration unit will automatically
start if the current temperature is 0.5ºC higher than
the set temperature (the temperature is set to 20ºC
before shipment). The refrigerator must be switched
on manually using the switch on the control panel,
once on, it will automatically cut in and out to
control the temperature of the cooling medium.
