INSTALLATION PROCEDURE
Selecting and Locating Hoses
•
The coolant ports are located on the rear of the system and are labeled as previously shown on page 13.
•
To minimize the pressure loss in the coolant lines, use the largest practical diameter tubing. If substantial
lengths of cooling lines are required, they should be pre-filled with coolant before connecting them to the
chiller.
•
To minimize heat gain, all lines should be as short as possible. Keep them away from heat sources such as
radiators and hot water pipes. Lines that cannot be routed away from heat sources should be protected
with thermal insulation, preferably at least 1/2" (12.7mm) thick.
•
Flexible tubing should be of heavy wall or reinforced construction. All tubing should be rated to withstand
125 psig (9 bar) at 86°F (30°C).
Make sure all tubing connections are secured and leak-tight. Also,
whenever possible use opaque lines to prevent algae growth during prolonged non-operating periods.
Connecting Plumbing
To connect the fluid lines to the chiller and user equipment follow these steps:
1. Remove the plastic caps covering the supply and return ports on the rear panel of the unit.
2. Attach coolant lines to the supply and return ports on the rear panel. Fittings should either be brass,
stainless steel or nylon.
Never use steel or cast iron fittings, as the corrosion will damage
the chiller. For chillers with de-ionization cartridges or high purity plumbing Lytron recommends the use of
either stainless steel or nylon fittings. The supply port provides chilled coolant to the user’s equipment. The
return port connects to the outlet of the user’s equipment.
3. Check that fittings are tight to prevent leaks.
4. Remove water filler cover on top of the unit to access the reservoir.
5. Fill the reservoir. Use the reservoir sight tube on the front of the unit to see the coolant level in the tank
during filling. Be sure to allow for the volume of coolant needed to fill the cooling lines between the chiller
and the equipment, if they were not filled with coolant before installation.
6. If the system is a water-cooled chiller, connect facility water to connections labeled "City Water In" and "City
Water Out". Minimum flow rate of facility water is shown on page 15. Facility water flow must be started
before chiller is turned on.
