vertical capacity equal to the total machine weight.
5. The machine must be lifted slowly and well leveled. It
is recommended to initially lift the unit to a low height
to verify all rigging equipment is properly installed and
unit is level. Adjust the lifting equipment, if necessary, to
ensure the leveling and re-lift.
6. If not able to lift the unit directly into place and must
go through a door for installation, a certified, licensed
professional rigger must determine the lifting and rigging
process as required by the site specific installation.
Unit Placement
The unit must be mounted on a level cement or steel base,
suitable to support the overall weight of the complete machine
in operation, and must be positioned so as to provide space for
maintenance at one end of the unit, to allow the cleaning and/
or the removal of the evaporator and the condenser tubes. The
condenser and evaporator tubes are expanded inside the tube
sheets to allow replacement, if necessary. Refer to
below for clearance requirements.
The machine position should be designed to ensure access
to all the safety and control devices. Never cover the safety
devices (safety valves, pressure switches). The safety valves
must be connected externally.
These units include the installation of safety valves for each
exchanger, installed on an exchange tap, which always
maintains an active valve. Thus, safety valves must be
connected outside of the equipment room.

Mounting Hole Access
After positioning, the shipping rails should be removed and the
machine must be firmly anchored to the ground or foreseen
metal structure to support the machine. In this regard, 0.87 in
(22 mm) diameter holes are included on the unit supports for
securing mounting bolts, etc. Mounting location dimensions are
given in Dimensional Drawings beginning on
mounted, the base of the unit must be level to within ± ½ inch
(12.7 mm) across the length and width of the unit.
Service Access
The control panels are located on the front of the chiller and
require a minimum of four feet of clearance in front of the
panels.
Disconnect, lockout and tag all electrical power to the unit
before servicing compressors and/or recovering refrigerant.
Failure to do so can cause bodily injury or death.
Clearance Requirements
The unit must be placed in an area that allows for adequate
clearance around the unit. See
requirements around the sides of the chiller. Doors and
removable wall sections can be utilized to meet these
clearance requirements. There must be a minimum of 3 to
4-feet clearance above the top of the chiller. The U.S. National
Electric Code (NEC) or local codes can require more clearance
in and around electrical components and must be checked for
compliance.
