INSTALLATION PROCEDURE
Selecting and Locating Hoses
x
The coolant ports are located on the rear of the system and are labeled as previously shown.
x
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.
x
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).
x
Flexible tubing should be of heavy wall or reinforced construction. All tubing should be rated to
withstand 125 psig at 186
o
F (30
o
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.
THE SUPPLY PORT: Provides chilled coolant to the user’s equipment.
THE RETURN PORT: Connects t o the outlet of the user’s equipment.
*FACILITY WATER IN: Supply LCS unit with Facilities water.
FACILITY WATER OUT:
Discharge Facility water from LCS unit.
*NOTE: To maintain a process water temperature of 120° F. (49 C), the facility water should have
a flow of 8.0 GPM minimum at a temperature of 80°. (27 C). Maximum facility water pressure
should be 100 PSI and no greater than 35 psid across LCS.
A pressure drop of greater than 35 psid across the LCS facility circuit could result in
premature valve wear and damage to 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 as you are 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.
In order to maintain process setpoint facility water must be started before the LCS is
turned on.
