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.

Transportation –OPC3 through OPC30
•Transport the chiller using the fork pockets or rigging lift points. Ensure forks are past the
chiller center post.
•If rigging the chiller, lift only from the points shown below. Proper rigging technique, including
spreader bars, is critical to avoid damaging the chiller.
•Do not remove any panels from the chiller during the rigging process.
•See below for rigging and lift points.

IV. Installation: Line Sizing, Piping
Line Sizing
Contact Haskris for help: Haskris is available to review pipe runs, pressure drop, etc. and make
recommendations for individual sites.
Approach to line sizing
•Size all interconnecting hose and piping equal to or larger than the connections on the chiller.
•Pressure drop in the external piping is a function of fluid flow rate, pipe inner diameter, pipe
length, the number and type of fittings, and other factors.
•Generally, external piping should be sized to minimize pressure drop. Approximately 5 psi to
10 psi (0.34 bar to 0.7 bar) or less is a good goal
For applications requiring approximately 50 LPM (13.2 GPM) or less
•If the total straight pipe length is less than 1,100 ft (335 m) use 1-1/2” nominal pipe size (ID).
For applications requiring approximately 100 LPM (23.8 GPM) or less
•If the total straight pipe length is less than 300 ft (91.4 m) use 1-1/2” nominal pipe size (ID).
•If the total straight pipe length is less than 1,200 ft (366 m) use 2” nominal pipe size (ID).
For applications requiring approximately 150 LPM (31.7 GPM) or less
•If the total straight pipe length is less than 120 ft (36.6 m) use 1-1/2” nominal pipe size (ID).
•If the total straight pipe length is less than 500 ft (152 m) use 2” nominal pipe size (ID).
For applications requiring approximately 200 LPM (52.8 GPM) or less
•If the total straight pipe length is less than 50 ft (15.2 m) use 1-1/2” nominal pipe size (ID).
•If the total straight pipe length is less than 310 ft (94.5 m) use 2” nominal pipe size (ID).
•If the total straight pipe length is less than 925 ft (282 m) use 2-1/2” nominal pipe size (ID).

Piping
•Comply with local codes for proper piping.
•Use type L copper piping and non-ferrous materials. Do not use black steel piping.
•Insulate piping to minimize condensation.
•Terminate the beginning and ends of hard runs with vibration isolators.
•Ensure piping is clean and free of flux at solder joints.
•Install manual ball valves at high points in the piping for purging air while filling the lines.
oIf automatic purge valves are used, isolation ball valves should be installed before the
purge valves.
oPurge valves must be closed during normal operation.
•Install drain valves at the base of every rise for emptying the lines.
•Install a heat trace on piping exposed to temperatures below +20°F (-6.7°C). Cover heat trace
with closed cell UV resistant insulation. Power the heat trace from a dedicated disconnect.
oHeat trace is specified to provide additional protection against freezing in a scenario
where the chiller loses power during extremely cold ambient conditions for an extended
period of time.
•Label supply and return lines over insulation with arrows indicating flow directions.
•Install isolation ball valves on the supply and return connections at the chiller.
•Install flush ports with isolation valves after the supply and return ball valves.
•Sleeve and insulate pipe penetrations through all roof and/or walls.
•Install a loop of reinforced opaque hose between supply and return connections at indoor
location for flushing.
•After the lines are flushed, connect the lines to the application.
Devices that are not recommended: Haskris does not recommend that any of the following are used
in the piping system, without consultation with Haskris.
•Chemical feeder systems
•Expansion tanks
•Electronic regulation or shut off valves
