Fluid lines should be unobstructed without any hard bends in the run. Install gasket inside fittings before
use.
Apply a rag to wipe the parts clean after washing away stains; do not use hard objects.
Do not use flammable, corrosive or explosive substances on, in, or near the equipment.
Do not run the liquid pump dry.
The compressor requires 15 minutes to rest before operating after being shutdown. Do not allow the
compressor to cycle more than 5 times per day.
If there is a problem, do not continue to use the chiller. Contact us immediately.

1.2 Features
The UHC Series of high-performance closed loop recirculating heater chillers, use internationally
recognized phase change compressors. High quality 304 stainless steel construction and a nickel-plated
heat exchanger helps to inhibit corrosion. The pump can move your transfer fluid quickly. Casters aid in
the portability of the chillers When connected to a reactor, the UHC can maintain consistent sub-zero or
overboiling temperatures. Large changes in temperature can be achieved rapidly.

[ Prior to running the chiller, your fluid loop should be setup and the tank filled ]
Press Set (14) to enter the temperature set menu. Adjust the value using the Up (15) or Down (16). Then
Press Set (14) again to save the desired value (5). Next press Loop (10), then Cooling (11) and Heating
(12). This turns on the fluid pump, heating, and cooling.

5 Instructions for Installation
Precautions: Wait 12-hours after receiving shipment.
The compressor oil can run out of the compressor and up refrigerant lines. So, if you don't wait, the
compressor will pump without sufficient oil.
Place chiller in a climate-controlled facility with adequate ventilation around all sides. 1 foot minimum.
Units returned that have signs of outside use. Will automatically be determined to be improperly used and
cared for.
Steps:
•Unpack. Check for broken or missing tank level glass tube.
•Place unit in final location with 1’ ventilation around unit.
•Add gaskets into tubing.
•Install tubing from outlet to top of jacket, inlet with valve to bottom of jacket.
•Fill the tank up to 3/4 with silicon oil.
•Turn on the loop and watch the level indicator. When it drops to 1/3. Stop the loop and add more
silicon oil. Repeat until the jacket is full and the level indicator reads 3/4 full.
•Set the temperature.
•Enable heating and cooling. If the loop is off, heating and cooling won’t enable.
6 Notes
6.1 Purpose
The UHC Series is intended to be used in conjunction with a reactor. If not used with a reactor,
performance and accuracy cannot be guaranteed. The UHC is a small capacity flow through heater and
heat exchanger for liquid jackets in reaction vessels.
6.2 Storage
For long periods, please disconnect the power. Empty the tank and purge the pump.
7 Maintenance
•Shut off the power switch and disconnect the power cord before any maintenance.
•Use a damp soft cloth to wipe clean. Stubborn stains should be cleaned by neutral detergents.
•The maintenance of internal electrical and heating parts must be performed by professionals or
trained electricians.
•Do not directly splash water over the product or use abrasive powder, diluent, oil, kerosene,
acidic material and similar substances during cleaning, or else shock or other accidents will
occur.
