Section 2 Installation
4. Add together the
calculated rise
,
calculated drop , and horizontal
distance
to get the
total calculated
distance . If this total exceeds 150 feet
(45 meters), move the condenser/
condensing unit to a new location and
perform the calculations again.
Maximum Line Set Distance Formula
Step 1.
Measured Rise (R) 35 feet (10.7 meters)
Maximum
_____ x 1.7 =
_____ Calculated Rise
Step 2.
Measured Drop (D) 15 feet (4.5 meters)
Maximum _____ x 6.6
=
_____ Calculated Drop
Step 3.
Measured Horizontal Distance (H) 100 feet
(30 meters) Maximum
_____ Horizontal Distance
Step 4.
Total Calculated Distance 150 feet (45
meters) Maximum
_____ Total Calculated
Distance
Notice
The refrigeration system warranty will
not apply if the Manitowoc Ice Machine
and Manitowoc CVD Condensing Unit are
not installed according to specifications.
This warranty also will not apply if the
refrigeration system is modified with a
condenser, heat reclaim device, or other
parts or assemblies not approved by
Manitowoc.
REMOTE CONDENSER MODELS
Step 1 Secure the Condenser.
Through-holes are provided to secure
the condenser to a curb, rack or wooden
timber.
n
Warning
The ice machine head section contains
refrigerant charge. The ice machine head
section contains refrigeration valves
that must remain closed until proper
installation of the line sets is completed.
n
Warning
Electrical power to the ice machine head
section, condensing unit or condenser
must be disconnected before proceeding.
Step 2 Route the Refrigeration Tubing.
Route the refrigeration tubing between
the ice machine head section and the
condenser.
• Maximum line set exposed on rooftop is
25% of total line set length.
• A qualified person must perform all roof
penetrations.
• Interconnecting wire must be routed
between the ice machine and condenser.
Step 3 Connect the Line Set.
In most cases, by routing the line set
properly, shortening will not be necessary.
When shortening or lengthening is
required, do so before connecting the
line set to the ice machine or the remote
condenser. This prevents the loss of
refrigerant in the ice machine or condenser.
The quick connect fittings on the line sets
are equipped with access valves. Use these
valves to recover any vapor charge from the
line set.
