RW SERIES REVERSIBLE CHILLER INSTALLATION MANUAL
Safety Considerations
Installing and servicing air conditioning and heating equipment can
be hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install, repair
or service heating and air conditioning equipment. When working
on heating and air conditioning equipment, observe precautions in
the literature, tags and labels attached to the unit and other safety
precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for brazing operations. Have fire extinguisher
available for all brazing operations.
NOTE:
Before installing, check voltage of unit(s) to ensure
proper voltage.
WARNING: Before performing service or
maintenance operations on the system, turn off main
power switches to the unit. Electrical shock could
cause serious personal injury.
Application
Units are not intended for heating domestic (potable water) by
direct coupling. If used for this type of application, a secondary
heat exchanger must be used.
Moving and Storage
Move units in the normal “Up” orientation as indicated by the labels
on the unit packaging. When the equipment is received, all items
should be carefully checked against the bill of lading to ensure
that all crates and cartons have been received in good condition.
Examine units for shipping damage, removing unit packaging if
necessary to properly inspect unit. Units in question should also be
internally inspected. If any damage is observed, the carrier should
make the proper notation on delivery receipt acknowledging the
damage. Units are to be stored in a location that provides adequate
protection from dirt, debris and moisture.
WARNING: To avoid equipment damage, do not leave
the system filled in a building without heat during
cold weather, unless adequate freeze protection
levels of antifreeze are used. Heat exchangers do not
fully drain and will freeze unless protected, causing
permanent damage.
General Installation Information
Unit Location
Provide sufficient room to make water and electrical connections.
If the unit is located in a confined space, provisions must be made
for unit servicing. Locate the unit in an indoor area that allows easy
removal of the access panels and has enough space for service
personnel to perform maintenance or repair. These units are not
approved for outdoor installation and, therefore, must be installed
inside the structure being conditioned. Do not locate units in areas
subject to freezing conditions.
WARNING: Do not store or install units in corrosive
environments or in locations subject to temperature
or humidity extremes (e.g. attics, garages, rooftops,
etc.). Corrosive conditions and high temperature
or humidity can significantly reduce performance,
reliability, and service life.
WARNING: To avoid equipment damage and possible
voiding of warranty, be sure that properly sized
strainers are installed upstream of both brazed plate
heat exchangers to protect them against particles in
the fluid.
