ELECTRICAL AND PHYSICAL DATA
The information contained in this manual has been prepared to assist in the proper installation, operation
and maintenance of the chiller. Improper installation, or installation not made in accordance with these
instructions can result in unsatisfactory operation and/or dangerous conditions and can cause the related
warranty not to apply.
Read this manual and any instructions packaged with separate equipment required to make up the system
prior to installation. Retain this manual for future reference.
Separate and independent power supplies and disconnects must be provided. These chillers have
separate and discreet power requirements within one cabinet.
All power to the chiller must be turned off prior to opening cabinet and or servicing.
Failure to properly ground chiller can result in death.
Disconnect all power wiring to chiller before maintenance or service work. Failure to do so can
cause electrical shock resulting in personal injury or death.
All wiring must be done in accordance with the NEC (National Electric Code) as well as state and
local codes, by qualified electricians.
Product warranty does not cover any damages or defect to the chiller caused by the attachment or
use of any components, accessories or devices (other than those authorized by the manufacturer) into,
onto or in conjunction with the chiller. You should be aware that the use of unauthorized components,
accessories or devices may adversely affect the operation of the chiller and may also endanger life and
property. The manufacturer disclaims any responsibility for such loss or injury resulting from the use of
such unauthorized components, accessories or devices.
Upon receiving the chiller and components, inspect for any shipping damage. Claims for damage,
either apparent or concealed should be filed immediately with the shipping company.
No liquid other than the solution of water and propylene glycol (mixed in accordance with table
6) shall be used in the piping system.
Corrosive environments may subject metal parts of the chiller to rust and deteriorate. The
oxidation could shorten the chiller’s useful life. Corrosive elements include salt spray, fog or mist in sea
coastal areas, sulfur or chlorine from lawn watering systems and various chemical contaminants from
industries such as paper mills and petroleum refineries.
If the unit is to be installed in an area where contaminates are likely to be a problem, special attention
should be given to the equipment location and exposure.
• Avoid having lawn sprinklers spray directly on the chiller cabinet.
• In coastal areas, locate the chiller on the side of the building away from the water front.
• Elevating the chiller off of its slab or base enough to allow air circulation will help avoid holding water
in contact with the cabinet base.
• Regular maintenance will reduce the build-up of contaminants and help protect the cabinet finish.
• In severe locations having the chiller coated with an “epoxy” or other coating formulated for air
conditioning systems located in coastal areas may be necessary.
