Ventilation
The unit produces heat even though
the compressor is cooled by the
refrigerant . Make provisions to
remove heat generated by unit
operation from the equipment room.
Ventilation must be adequate to
maintain an ambient temperature
lower than 40°C.
Vent the evaporator, condenser, and
compressor pressure-relief valves
venting.
Make provisions in the equipment
room to keep the chiller from being
exposed to freezing temperatures
(0°C).
Water drainage
Locate the unit near a large capacity
drain for water vessel drain-down
during shutdown or repair.
Condensers and evaporators are
provided with drain connections.
Refer to “water piping“.

To prevent unit damage, position
the lifting beam so that cables do
not come in contact with the unit.
Do not use the threaded holes in the
compressor to lift, or assist in lifting,
the unit. They are not intended for
that purpose and could create a
dangerous situation.
Do not remove the wood shipping
mounts until the unit is in its final
location. Removal of wood shipping
mounts prior to unit final locating
could result in injury or death and
equipment damage.
Connect an anti-rotation strap
between the lifting beam and the
compressor before lifting the unit.
Failure to do so may result in
personal injury or death, if a lifting
cable fails.

Access restrictions
Door clearances for the RTWB units
are given in Figure 8. Refer to the
unit submittals for specific “per
unit“ dimensional information.
Lifting procedure
The unit can be moved by using a
fork lift or chains, cables, and a
lifting beam. The total lifting weight
and required lifting-beam
dimensions are shown in Figure 5
and on the lifting diagram shipped
with each unit. Lifting-beam
crossbars must be positioned so
that lifting cables do not come in
contact with the sides of the unit.
