II. Confirm Chiller Model and Number of Frame Sections
Frame Sections
Details: The Haskris OPC series chillers are built with a system of parallel refrigeration circuits and
associated frame sections to house those components. Larger models of chiller have more
refrigeration circuits and more frame sections.
Instructions: Use the chiller model and the table below to determine the number of refrigeration
circuits and sheet metal sets are used in the design.

III. Installation: Foundation, Vibration, Elevation, Clearances,
Transportation
Foundation
•The chiller must be installed on a level concrete foundation, level roof curb, or level perimeter
beam system.
•Comply with local codes for proper anchoring and vibration isolation.
•Use of a level roof curb or perimeter beam system requires the specifying engineer to identify
all necessary materials of construction, thickness, and additional bracing or supports.
•See the diagrams below for mounting hole locations.
oNote that the example in the drawings has a cutaway that shows 2.5 frame sections.
The actual number of sections varies, refer to the prior section for details.
•Point load at each mounting location is 200 lbs. or less.

Vibration
•The chiller does not require vibration isolation on the mounting for the chiller to operate
normally.
•The motors in the chiller are hard mounted to the metal structure of the chiller. They are not
internally isolated.
•It is common for the chiller to be hard mounted directly to a pad on grade, roof curb, or
perimeter beam system.
•If vibration transmission to the building structure is a concern, an engineer should provide a
detailed specification for vibration damping.
•There are two common approaches
oRubber or synthetic pads between the chiller and the mounting
oSpring vibration isolators. These cannot be installed directly between the chiller and the
mounting. The chiller must be mounted on a perimeter beam. The spring vibration
isolators can be installed between the beam and the mounting.
OSHPD: If OSHPD compliance is required and isolators are used, the spring isolators must comply
with Haskris OSHPD OSP-0673 file.

Elevation
For chillers located at a
higher
elevation than the application
•The maximum recommended height difference varies depending on several factors including
the maximum inlet water pressure for the application, normal water pump discharge pressure,
and pressure losses in the piping to the application.
•Consult Haskris if there are questions about locating a chiller.
For chillers located at a
lower
elevation than the application
•The maximum recommended height difference is 32 ft (9.8 m).
oIt is best if the height difference can be less than 32 ft (9.8 m).
oConsult Haskris if there are questions.
Clearances
•See the diagrams below showing recommended clearances for chiller models OPC3 through
OPC30.
oNote that these show the dimensions and clearances for a standard design. Some
customizations may alter the dimensions and/or clearance requirements. Consult
Haskris if there are questions about a specific design.
•For models OPC36 and larger, consult Haskris to get information about recommended
clearances.
•Air flow is horizontal into the chiller and vertical out of the chiller.
•Maintain an unobstructed space for free air discharge above the chiller.
•Consult Haskris if clearances will be smaller than these recommendations. Haskris will evaluate
individual site conditions as needed to ensure proper operation.
•Avoid areas where a heat source will discharge heat towards the chiller.
oExamples: condenser vents, heating exhaust, etc.
•Avoid areas where debris may accumulate on the condenser.
