Step 3 — Make Refrigerant, Evaporator Fluid
and Drain Piping Connections
SPLIT UNIT ASSEMBLY — The 30XV 400H, 450M,
450H, 500S, and 500M units are offered as two separate
modules from the factory as an option. This allows the units
to fit in containers for export shipping. Table 4 shows the
module designation.
Table 4 — Split Unit Sizes
These modules must be assembled in the field including braz-
ing and wiring. A split unit installation kit is provided for this
process. The kit is located in the control box of module A.
Steps for this assembly are below.
Module Placement — Place the modules in the final instal-
lation location in the orientation shown in Fig. 27. The ball
valves, open on one end, should be facing each other. There
may be a 0 to 2.0-in. (0 to 50.8 mm) gap between the units.
Brazing
The gas and liquid lines must be brazed together using stan-
dard refrigeration practices. The interconnecting tubes are in
the control panel in a box. Be sure plastic caps are removed
from ball valves on unit and connecting tubes. Figure 28 shows
the orientation of the tubes. If the joint is inaccessible by reach-
ing from under the braces, remove the rails. The tube with the
male connection may need to be trimmed to fit. Make sure the
ball valves remain closed until the brazing and vac process is
complete. Ball valves should be protected from heat by using a
wet rag. Schrader cores and fusible plugs should also be
removed from the interconnecting tubes supplied in the kit
prior to brazing. Nitrogen purge must be applied during braz-
ing. Schrader taps on ball valves can be used for a connection.
After brazing is complete:
• Leak check.
• Pull vacuum on the connection tube to at least 500
microns.
• Hold vacuum for 5 minutes to confirm braze integrity.
• Open all 4 ball valves to complete the connection pro-
cess.
NOTE: A nitrogen purge can be applied to this section. Con-
nections are at each ball valve.
Ball Valve Wiring —The 450H and 500M units have an auto-
mated discharge ball valve on the B module. See Fig. 29. A ca-
ble is tied on the end of the A module. Route the cable to the
ball valve and connect to the actuator using the plugs. Secure
the cable using wire ties, making sure the cable is not against
tubes or sharp edges.
Units may be ordered with manual ball valves instead of the
automated valve option. For this case, there is no wiring
required for the valves.
CAUTION
Units are designed for Victaulic-type water-side connec-
tions. If chilled water piping is to be welded to the water
nozzles, remove the chilled water flow switch, entering and
leaving water thermistors before welding connecting pip-
ing. Reinstall flow switch and thermistors after welding is
complete. Failure to remove these devices may cause unit
damage.
CAUTION
Factory-supplied insulation is not flammable but can be
damaged by welding sparks and open flame. Protect insu-
lation with a wet canvas cover. Failure to protect insulation
may cause unit damage.

CAUTION
The ball valves on the liquid and discharge line must
remain closed prior to brazing the mating tubes and pulling
a vacuum on this area for both liquid and discharge side.
Do not open the valves until indicated in the brazing
instructions below. Failure to follow the steps below could
result in a release of refrigerant or air and moisture in the
system. Work should be performed by a skilled HVAC
technician.
