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 in-
spected. 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.
Units are setup to be side picked using a fork lift. Some
units include pick bars allowing for picking from the end
with required fork lengths. Note unit labels and markings
for safe picking points. Do not pick the unit up from points
not specified and keep the unit level during transport and
handling. Using improper equipment handling methods can
result in damage and/or void the warranty.
Unit Location
Provide sufficient room to make water and electrical con-
nections. If the unit is located in a confined space, provi-
sions 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.
NOTICE: 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.
NOTICE: Do not store or install units in corrosive
environments or in locations subject to temperature
or humidity extremes. Corrosive conditions and high
temperature or humidity can significantly reduce
performance, reliability, and service life.
NOTICE: 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.

3. Place the floating flange and hand thread one bolt in the valve body. Place the flange sandwich plate between the valve
seal and the flange seal. Add the rest of the bolts and only hand tighten. Center the sandwich plate using a ruler or a tool
with marking of the correct distance between the ring and outer diameter of the flange (SEE Figure 4). Failure to center
the ring correctly can cause a leak.
4. Rotate the valve assembly to a desired angle or to the suggested orientation in the assembly drawing shown in Figure 5.
Once the ring is centered tighten all bolt to 40ft-lb following the pattern shown in Figure 5.
5. Add the second floating flange to the assembly. Thread one bolt to the valve body and hand tighten. Add the floating
flange sandwich plate while pushing the header assemblies apart. Add the rest of the bolts and hand tighten. Center the
flange in the same way as shown in step 4. Tighten all bolts.
6. Tighten the large header grooved clamps.

High Pressure Refrigerant Relief Venting
All TruClimate 700 Series units utilize a refrigerant-pressure relief valve which must be vented to the outdoor atmosphere.The
valves are located on the discharge piping and have a 1” FPT connection.See figure below for guidance on connecting to
the pressure relief valve inside the chiller enclosure.In cases of multiple chillers installed as a bank, each unit may be piped
separately or the chillers can be vented together.In either case, always refer to local codes and ASHRAE 15 for relief valve line
sizing requirements.High side pressure relief valve discharge setpoints are 300 psig for TruClimate 700 Series with R-513A
refrigerant.Once the relief valve has opened, it will close when the pressure is reduced to a safe level.

Temperature Headers
Temperature headers will need to be installed between the
building and chiller connections. DP transducers must be
installed at the bank level to monitor water flow through the
bank.
Bypass Headers
Bypass headers will need to be installed between the chiller
outlet and the building connection with the temperature
sensors on the building side of the bypass.
Water Piping
Water Piping must be installed in accordance with applica-
tion codes and per necessary standards. Supply and return
connections should be connected per units’ directions.
Strainers are required on supply to machine per engineer
specification to prevent heat exchanger fouling from occur-
ring.
Before start-up can occur, water must be CLEAN and
proper procedures and care should be implemented in
order to ensure and maintain a clean system. Water should
be treated and clean per necessary standards before start-
up is scheduled. Each water header is equipped standard
with a temperature well sensor for supply and return water
temperatures of the units’ performance. Also included is a
flow switch located on the exit side of the heat exchanger
to ensure flow through the heat exchangers, which is in-
tegrated into the controls and is adjusted in pre-shipping
testing procedures.
Furthermore, it is recommended to provide water isola-
tion valves for proper isolation and maintenance of the unit,
pumps, and strainers.
