II. Technical Requirements
Dimensions
•Note that the dimensions below are for the majority of standard configurations. Some units
may have custom dimensions according to alternative design configurations.
•Dimensions of LX1 and LX2 are 15” W x 32” D x 30” H (38.1cm W x 81.3cm D x 76.2cm H)
•Dimensions of LX3 are 19” W x 34” D x 34” H (48.3cm W x 86.4cm D x 86.4cm H)
Clearances
•Maintain at least 6 inches (15 cm) clearance on the sides and rear for sufficient air flow.
•Maintain at least 36 inches (91 cm) on the front for access to the main controller during
normal operation.
•Maintain access to the top of the unit.
•Additional clearances on the sides and rear may be required for service.

Location
•Locate the unit in a clean indoor environment.
•For units with air-cooled condensers, confirm ambient air temperature is compatible. Confirm
the climate control system has enough spare capacity to accept heat rejection from the chiller.
Refer to the table below.
Haskris Chiller

LX1
55°F to 90°F (13°C to 32°C)
7,510 BTU/hr (2.2 kW)
LX2
55°F to 90°F (13°C to 32°C)
15,020 BTU/hr (4.4 kW)
LX3
55°F to 90°F (13°C to 32°C)
29,700 BTU/hr (8.7 kW)
*Some units are designed with customizations to accommodate extended ambient temperature ranges,
contact Haskris with any questions

•For units with water-cooled condensers, confirm the building water source can provide water
at the required temperature and flow rate. Refer to the chart below.
oInstall hand valves in an accessible location on the facility water inlet and outlet.
oInstall an 80 mesh wye strainer on the facility water inlet. Do not install filters.
oConfirm the maximum inlet pressure is less than 100 psi (6.9 bar)
oConfirm the minimum available differential pressure is 10 psi (0.7 bar)
oConfirm the maximum differential pressure is 100 psi (6.9 bar)
Water-cooled Condenser: Required facility water flow rate

III. Installation
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
(0.34 bar) or less is a good goal.
For applications requiring approximately 8 LPM (2.1 GPM) or less
•If the total straight pipe length is less than 90 ft (27.4 m) use 1/2” nominal pipe size (ID).
•If the total straight pipe length is less than 250 ft (76.2 m) use 5/8” nominal pipe size (ID).
•If the total straight pipe length is less than 475 ft (144.8 m) use 3/4” nominal pipe size (ID).
For applications requiring approximately 16 LPM (4.2 GPM) or less
•If the total straight pipe length is less than 25 ft (7.6 m) use 1/2” nominal pipe size (ID).
•If the total straight pipe length is less than 75 ft (22.9 m) use 5/8” nominal pipe size (ID).
•If the total straight pipe length is less than 140 ft (42.7 m) use 3/4” nominal pipe size (ID).
•If the total straight pipe length is less than 550 ft (167.6 m) use 1” nominal pipe size (ID).
For applications requiring approximately 23 LPM (6.1 GPM) or less
•If the total straight pipe length is less than 40 ft (7.6 m) use 5/8” nominal pipe size (ID).
•If the total straight pipe length is less than 75 ft (22.9 m) use 3/4” nominal pipe size (ID).
•If the total straight pipe length is less than 300 ft (91.4 m) use 1” nominal pipe size (ID).

Piping
•Comply with local codes for proper piping.
•For short runs, use opaque 150 psi minimum rated reinforced EPDM hose. Do not use clear
braided hose.
•For long runs, use copper piping. Terminate the beginning and end of hard runs with vibration
isolators or a short segment of hose to absorb vibration.
•Insulate piping to minimize condensation.
•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.
•For water-cooled units, it is recommended to install an 80-mesh wye strainer at the building
water inlet. This will provide some protection for the chiller’s condenser if the facility water has
particulate contaminants.

Electrical
•Comply with proper local electrical codes.
•Contact a licensed electrician to perform the electrical installation.
•The electrician should verify that the wiring is adequate in the installation area.
•Refer to the nameplate label on the rear of the unit for detailed electrical requirements.
Power cord: Some units include a power cord. Hardwire the power cord to an electrical service
disconnect or add a plug with the appropriate rating and type.
For units without a power cord, connect incoming power to the labeled terminal block inside the
unit’s electrical enclosure.
Service disconnect: Use a dedicated service disconnect and time-delay fusing or circuit breaker per
the electrical requirements on the unit’s nameplate label.
Phase monitor: Chillers configured for 3-phase electrical include a phase monitor. Refer to the fault
indicators provided on the phase monitor and contact a licensed electrician to correct any faults.

Phase fault LED status patterns
Energizing the service: Electrical power must be applied to the chiller at least 12 hours in advance of
startup. This energizes the crankcase heater and drives out any accumulated liquid refrigerant in the
compressor.
