Installation overview and
requirements
Contractor responsibilities
A list of the contractor responsibilites typically associated
with the installation process is provided in Table 2.
• Locate and maintain the loose parts. Loose parts are
located in the control panel.
• Install the unit on a foundation with flat support surfaces,
level within 5 mm and of sufficient strength to support
concentrated loading. Place the manufacturer-supplied
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 1m of clearance
between the pre-installation piping and the planned location
of the unit. This will allow for proper fit-up upon arrival
of the unit at the installation site. All necessary piping
adjustments can be made at that time
• Where specified, supply and install valves in the water
piping upstream and downstream of the evaporator and
condenser, to isolate the heat exchangers for maintenance
and to balance/trim the system.
• Supply and install flow switches or equivalent devices
in both the chilled water and condenser water piping.
Interlock each switch with the proper pump starter and
Tracer UC800, to ensure that the unit can only operate
when water flow is established.
• Supply and install taps for thermometers and pressure
gauges in the water piping, adjacent to the inlet and outlet
connections of both the evaporator and the condenser.
• Where specified, supply and install strainers ahead of all
pumps and automatic modulating valves.
• Supply and install refrigerant pressure relief piping from
the pressure relief to the atmosphere.
• Start the unit under supervision of a qualified service
technician.
• Where specified, supply and insulate the evaporator
and any other portion of the unit, as required, to prevent
sweating under normal operating conditions.
• For unit-mounted starters, cutouts are provided at the top
of the panel for line-side wiring.
• Supply and install the wire terminal lugs to the starter.
• Supply and install field wiring to the line-side lugs of the
starter.
