Connecting Power
Requirements:
•
The unit construction provides protection against the risk of electrical shock by grounding
appropriate metal parts. The protection will not function unless the power cord is connected to
a properly grounded outlet. It is the user’s responsibility to assure a proper ground connection
is provided.
•
Power Cord with C19 connector (not supplied by Laird Thermal Systems)
•
Use cable rated for 20A 250V with IEC320-C19 receptacle. The customer side of the cable
must follow required standard for the country of installation
Procedure
1. Cable with a ‘C19’ Connector should be connected to the IEC power connection on unit as
shown below.
2. Turn the Power Switch ON.
3. When the Power Switch is ON, the Power Switch should light up as well as the LCD Panel.

Adding Coolant and Priming Unit
The unit is not intended for use with corrosive fluids. Automotive Antifreeze should never be used as a
freezing point depression or corrosion protection fluid. Automotive antifreeze contains additives that
can damage system components and will void the warranty.
Approved fluids and their normal operating temperature ranges are:
Filtered/Single Distilled water, +10°C to +40°C
Up to 50% Inhibited Ethylene Glycol (EG) /Water, -10°C to +40°C
Up to 50% Inhibited Propylene Glycol (PG) /Water, -10°C to +40°C
Deionized water ( up to 3 MΩ
-cm
*
), +10°C to +40°C
It is important to maintain the proper mixture of EG or PG and water over time. Instruments are
available on the market for measure glycol content and should be used periodically and when refilling
the system to check the coolant mixture ratio.
Inhibited EG or PG should be used when the coolant is being exposed to aluminum components in
order to prevent galvanic corrosion. Because inhibitors increase the fluid conductivity of the coolant
