INTRODUCTION
The chilled water storage tank accessory permits a storage tank to
be mounted under the 30RAP chiller. Chilled water storage is rec-
ommended on some applications to maintain a desired loop vol-
ume, allowing the chiller to achieve the desired performance and
control compressor cycling. See Table 1for usage.
Located in the control box included with the accessory are fasten-
ers to attach the chiller to the accessory tank. In addition to the
parts supplied with the accessory package, the following material
must be field-supplied:
• Water piping between the tank system and the chiller
• Tubing insulation (length determined by installation)
Table 1 — Package Usage
SAFETY CONSIDERATIONS
Installing, starting up, and servicing air-conditioning equipment
can be hazardous due to system pressures, electrical components
and equipment location.
Only trained, qualified installers and service technicians should in-
stall, start up, and service this equipment.
When installing this accessory, observe precautions in the litera-
ture and on any labels attached to the equipment, and all other
safety precautions that may apply.
• Follow all safety codes.
• Wear safety glasses and work gloves.
• Keep quenching cloth and fire extinguisher nearby when
brazing.
• Use care in handling, rigging, and setting bulky equip-
ment. Refer to Table 2 for tank weights and Fig. 1 and 2
for rigging and weight information.
INSTALLATION
Step 1 — Rig and Place the Tank
RIGGING
Use spreader bars to rig the unit at a single point with 4 cables and
hooks. Refer to the rigging label on the accessory for details con-
cerning rigging options, shipping weights, distance between lifting
holes, and center of gravity. See Fig. 1.
If overhead rigging is not possible, the accessory may be lifted
from either end, but care must be taken to align forks to slots pro-
vided in each rail for support. Care must be taken not to hit or
damage insulated tanks with forks.
PLACING ACCESSORY TANK
Determine the location of the accessory and 30RAP unit together.
Ensure that the location supports the filled weight of the tank sys-
tem and the chiller. See Table 2and Fig. 2-5 for weights and di-
mensions. Since the 30RAP chiller mounts on top of the accesso-
ry, there must be at least 3 ft (0.9 m) for servicing and for unre-
stricted airflow on all non-coil sides of the unit, and a minimum of
3.5 ft (1.1 m) clear air space on coil sides. For multiple units, allow
8 ft (2.5 m) separation between units for airflow and service.
MOUNTING ACCESSORY TANK
When the accessory is in the proper location, the use of mounting
holes in base rails is recommended for securing the accessory to
supporting structure, or for mounting the accessory on vibration
isolators if required. See Fig 3-5. Fasteners for mounting the ac-
cessory are field supplied. Be sure the accessory is level to within
1/8 in. per foot for proper oil return in the 30RAP chiller mounted
on top.

NOTE: Remove all packaging before mounting the accessory tank
to the unit.
MOUNTING UNIT TO ACCESSORY TANK
The 30RAP chiller mounts on top of the rails of the tank accesso-
ry. The 30RAP chiller piping connections should be located near
the end of the accessory tank that has the piping connections. This
will minimize field piping between the chiller and the accessory
tank. The use of mounting holes in chiller base rails to the tank ac-
cessory is required. Fasteners for mounting the chiller to the tank
accessory are provided and can be located in the control box.
Mounting the 30RAP chiller on vibration isolation pads between
the 30RAP chiller and the tank accessory is allowed but is not
required.

Step 2 — Connect Cooler Fluid and Drain Piping
The piping between the chiller and the accessory tank can be done
to allow the tank to be on the return side of the chiller (tank piped
to chiller inlet) or the supply side of the chiller (tank piped to the
chiller outlet). See Fig. 6. However, it is recommended that the
tank be piped to the return side of the chiller to buffer any changes
in load to allow more stable chiller operation. For digital compres-
sor applications, it is recommended that the tank be piped to the
supply side of the chiller to provide a more stable supply tempera-
ture. See Fig. 7and 8for an examples of piping layouts.
All sizes have 2-1/2 in. Victaulic connections. Provide a means of
venting air from the high point of the field-installed piping as re-
quired. All sizes also have 2 in. drains at the bottom of each end of
the storage tanks. This size has been provided to allow cleaning of
foreign material that may collect at the bottom of the tanks.
After field piping is complete, freeze protection is recommended
using inhibited ethylene glycol or other suitable inhibited anti-
freeze solution and electric heat tapes in area where piping is ex-
posed to low ambient temperatures (34°F [1°C] or below). Heat
tapes should be rated for area ambient temperatures and be cov-
ered with a suitable thickness of closed-cell insulation. Route
power for heating tapes from a separately fused disconnect. Identi-
fy disconnect as heat tape power source with a warning that power
must not be turned off except when unit is being serviced.
PREPARATION FOR YEAR-ROUND OPERATION
If unit is in operation year-round, add sufficient inhibited ethylene
glycol or other suitable inhibited antifreeze solution to chilled wa-
ter to prevent freezing under low-ambient operating conditions.
Consult local water treatment specialist on characteristics of water
and recommended inhibitor.
Fig. 6 — Typical Chiller/Tank Setup
PREPARATION FOR WINTER SHUTDOWN
Do not shut off electrical disconnect during off-season shutdown.
At end of cooling season:
1. Make sure LOCAL/OFF/REMOTE switch is in the OFF
position on the chiller.
2. Drain water from the accessory tank system.
3. Replace drain plugs and fill tanks with a rust inhibiting anti-
freeze solution to prevent freezing of residual water and rust
build-up.
4. At beginning of the each cooling season, refill cooler and add
recommended inhibitor.

Step 3 — Make Electrical Connections
POWER SUPPLY
The storage tank does not require a power connection to the tank
heater if the chilled fluid has been properly treated with a suitable
anti-freeze solution or the chilled fluid is drained during the winter
season. If this is the case, installation is complete and the tank
electric heater is not used.
ELECTRIC HEAT
The water storage tanks are provided with electric heaters to pre-
vent freeze-up during low ambient temperature conditions. The
heaters will provide freeze protection to –20°F (–28.9°C). Care
must be taken to prevent freeze-up in the event of a power loss.
CONDUIT CONNECTION
The tank power is provided from the main unit control box. Con-
duit is supplied in the accessory kit which needs to be installed be-
tween the main control box and the tank heater control box. Per-
form the following steps to install the conduit:
1. Make a 0.75 in. (19 mm) diameter hole using a drill or punch
per Fig. 9-11.
2. Knock out the conduit entry hole in the tank control box. See
Fig. 12.
3. Remove the conduit connector from the end of the conduit
opposite the end with ring terminals.
4. From inside the compressor section of the unit, feed the con-
duit through 0.75 in. (19 mm) hole made in Step 1.
5. Route the conduit between storage tanks to the storage con-
trol box and install connector removed in Step 3.
6. Make conduit connection to power entry hole in tank control
box shown in Fig. 12.
7. Make power connections in tank control box to TB1A. Con-
nect black wire to terminal 11. Connect yellow wire to termi-
nal 12. Connect green wire to ground connection.
8. Connect red and brown control wires from conduit to red and
brown wires in tank control box using wire nuts supplied in
hardware kit.
9. Check tank heater wiring for proper termination. See Fig. 13.
Accessories are shipped from the factory for high voltage
wiring and if applied at 208/230 volts, will not have freeze
protection down to –20°F (–28.9°C). A warning label is
affixed to the tank to alert installers if the power supply is
208/230 volts. See Fig. 14. For 208/230 v units, the heater
elements must be wired in parallel instead of series. Recon-
nect the black, red, and white wires in the tank heater wiring.
See Fig. 13.
NOTE: Tank heater wiring in both control boxes (control box
1 and 2) must be changed for the 30RA-900---052 accessory.
10. Relocate HPS and EXV wires for sizes 015-030 and HPS-B
wires for sizes 035-060 to compressor wire entry. See Fig. 15

OPERATION
A thermostat is mounted within the tank heater control box to reg-
ulate the water temperature. The thermostat is set to 55°F with a
deadband of 5°F. When a call for the heating is made, the heater
will turn on at 50°F and off at 55°F.
Restore power to the main unit and check heaters for proper oper-
ation. The tank heaters are in an operative state when the Emer-
gency On-Off switch on the chiller is in the OFF position, and the
thermostat is in closed position.
The tank heaters are wired in the control circuit so that they are op-
erable as long as the main power to the chiller is ON. A factory-in-
stalled and set overload device protects them.
NOTE: The field-supplied disconnect should never be off except
when the tank accessory and/or chiller are being serviced or are to
be down for a prolonged period, in which case the accessory tank
and chiller should be drained.
Storage tank pressure drop pressure drop curves are shown in
