Section 2 - Set Up
Before proceeding, be sure all power is off
2.1 Location
Locate the chiller on a strong, level surface. Insure easy access to the top cover and position the chiller for unobstructed air flow through the front and rear screens. The front wheels can be locked to keep the chiller in place while in use. Avoid voltage drops by using properly grounded power outlets wired with 14 gauge or larger diameter wire. If possible, be close to the power distribution panel. Minimize low line voltage problems by eliminating the use of extension cords.
2.2 Reservoir Fluids
For most applications above +15°C, distilled water is satisfactory. For operation below +15°C, the chiller MUST be protected with an antifreeze solution. Ethylene glycol (laboratory grade) and water in a 50/50 mixture is satisfactory from +15°C to
OR FLAMMABLE FLUIDS MUST NEVER BE USED.
Do not use a flammable fluid as a fire hazard may result.
WARNING!
Operation below +15°C requires antifreeze in the circulating fluid.
2.3 Pump, Hoses and Couplings
To maintain a safe workplace and to avoid leaks, special care should be taken when choosing hoses and connectors for the chiller.
1.Pressure ratings - Hoses should be able to withstand the largest pressure that they will encounter. For positive displacement pump models, this is 100 psi.
2.Flexible tubing - Avoid tubing that will expand and take up fluid volume when operating at the desired pressure.
3.Hose diameter - The fittings on the chiller Outlet and Inlet lines are internally threaded,
1/2 inch I.D. N.P.T. The 2 adapters sets supplied are for 1/2 inch I.D. tubing and 5/8 inch I.D. tubing. Other fittings can be used if a smaller hose diameter is desired. Remember that the operating pressure in the circulating system increases when using a smaller diameter hose.
