Refer to the Mechanical and Electrical sections of this manual for detailed instruc-
tions.
• Locate and maintain the loose parts such as, isolators, bulb wells, temperature sen
-
sors, flow sensors or other factoryordered field-installed options, as required. Loose
parts are located in the starter panel if equipped with a unit-mounted starter. If not
equipped with a unit-mounted starter, loose parts are shipped in the motor junction
box.
• Install the unit on a foundation with lat support surfaces, level within 1/4" (6 mm)
and of sufficient strength and mass to support the chiller operating weight. Place the
manufacturersupplied isolation-pad assemblies under the unit.
• Install the unit per the instructions outlined in the Mechanical Installation section.
• Complete all water piping and electrical connections.
Note: Field piping must be arranged and supported to avoid stress on the equipment.
It is strongly recommended that the piping contractor provide at least 3 feet (914 mm)
of clearance between the preinstallation piping and the planned location of the unit.
This will allow for the proper fit upon arrival of the unit at the installation site. All nec-
essary piping adjustments can be made at that time.
• Where speciied, supply and install valves in the water piping, upstream and down
-
stream of the evaporator and condenser water boxes, in order to isolate the shells for
maintenance and to balance and trim the system.
• Supply and install low switches or equivalent devices in both the chilled-water pip
-
ing and the condenser-water piping. Interlock each switch with the proper pump start-
er, to ensure that the unit can only operate when water flow is established.
Note: reference graphs 1-16 in the Installation Mechanical section for proper water
flow.
• Supply and install taps for thermometers and a pressure gauge manifold in the wa
-
ter piping, adjacent to the inlet and outlet connections of both the evaporator and the
condenser.
• Supply and install drain valves on each water box.
• Supply and install vent cocks on each water box.
• Where speciied, supply and install strainers ahead of all pumps and automatic mod
-
ulating valves.
• Supply and install refrigerant pressure-relief piping from the pressure-relief valve to
the atmosphere.
• If necessary, supply enough HFC-134a refrigerant (1 pound = .45 kg) and dry nitrogen
(75 psig = 517 kPa maximum) for leak testing.
• Evacuate the unit to less than 500 microns (0.5 mm Hg) or according to local code.
• Charge with refrigerant 134a.
• Go over the pre-commissioning check sheet and ensure that all items have been
completed.
• Start the unit under the supervision of a qualiied service technician.
