MAINTENANCE
5.1 RESERVOIR CLEANING
Periodically inspect the fluid inside the reservoir. If cleaning is necessary, flush the reservoir
with a cleaning fluid compatible with the circulating system and the cooling fluid.
The cooling fluid should be replaced periodically. Replacement frequency depends on the
operating environment and running time.
Before changing the cooling fluid ensure that it is at a safe handling temperature.
When fittings have to be changed or the chiller is not used for a long period, be sure to drain all
liquid out of the unit. Shut down the unit at first, then put a cup on the ground and disconnect
the fitting from the instrument cooled then let the fluid in the tank flow out into the cup and
disconnect the fitting on the chiller. Before positioning the unit in the storage be sure the drain
tap is closed.
5.2 CONDENSER CLEANING
For proper operation, the unit needs to pull a substantial amount of air through a condenser. A
buildup of dust or debris on the fins of the condenser will lead to a loss of cooling capacity.
The lower front of the unit has a one-piece grid assembly. Gently remove it using hands by
prying. Use care not to scratch the paint.
Periodic vacuuming of the condenser fins is necessary. The cleaning frequency depends on the
operating environment. After initial the installation we recommend a monthly visual inspection
of the condenser. After several months the cleaning frequency will be established.
Use care when cleaning the condenser fins, they can easily bend.
5.3 FILTER REPLACEMENT
If the water circuit of the unit is equipped with a filter system, please change the filter cartridge
periodically.
