The HX Series Recirculating Chiller is designed to provide a continuous flow of cooling fluid at a constant temperature and volume.
The unit should be located in a laboratory or clean industrial environment where ambient temperatures are inside the range of +55°F to +95°F.
The unit should be located in a laboratory or clean industrial environment with easy access to a facility cooling water supply and a drain.
Before installing the unit to an instrument that previously used tap water as a cooling fluid, flush the instrument.
Before starting, check all electrical and plumbing connections and make sure the recirculating system has been properly filled with cooling fluid.
Turn the calibrated dial until the desired temperature aligns with the reference line.
The flow control handle is connected to a valve that controls the flow rate of the cooling fluid to the instrument being cooled.
Units with a PD-1, PD-2, or any TU type pump are equipped with a pressure gauge.
Three phase units with three phase pump motors are equipped with a pump motor overload protector.
NESLAB offers on-site Service Contracts that are designed to provide extended life and minimal down-time for your unit.
A build up of dust or debris on the fins of the condenser will lead to a loss of cooling capacity.
To restrict the growth of algae in the fluid reservoir, it is recommended that the reservoir cover be kept in place and that all recirculation lines be opaque.
If debris is drawn into the recirculating system, the strainer will prevent the material from being sucked into the pump.
Unit will not start: Check power source for correct voltage output. Check house circuit breaker.
If, after following these troubleshooting steps, your unit fails to operate properly, contact our Service Department.
