Mounting Unit; Step 2 - Check Compressor Mounting; Step 3 - Cooler Fluid And Drain Piping; Connections - Carrier AquaSnap 30RAP010-150 Installation Instructions Manual

MOUNTING UNIT — When unit is in proper location, use
of mounting holes in base rails is recommended for securing
unit to supporting structure, or for mounting unit on vibration
isolators if required. See Fig. 10-18. Fasteners for mounting
unit are field supplied. Be sure unit is level to within
foot for proper oil return to compressor.
Step 2 — Check Compressor Mounting —
shipped, units with single compressors are held down with 4
bolts through rubber grommets. All units with tandem com-
pressors are held down with 6 bolts per pair through grommets.
After unit is installed, verify mounting bolt torque 7 to10 ft-lb
(9.5 to 13.6 Nm).
For 30RAP100-150 units, RED bolts from compressor
mounting rail must be removed. These RED bolts are for ship-
ping purpose only. Also remove the shipping braces that tie the
compressors in a circuit together. Using a 15-mm socket, loos-
en each bolt and nut on each compressor tab and remove all
braces before unit start-up.
Step 3 — Cooler Fluid and Drain Piping Con-
nections
ALL UNITS — These chillers are supplied with factory-
installed strainer (including blow-down valve) in the entering
fluid piping and flow switch in the leaving fluid piping. Flow
switch wiring is factory installed.
CAUTION
Do not circulate water through unit without strainer in
place. Failure to use the strainer represents abuse and may
impair or otherwise negatively affect the Carrier product
warranty.
Piping connections are located on the front of the chiller
when facing the control panel for sizes 010-030 and at the end
opposite the control panel for sizes 035-060. For sizes 070-150,
piping connections are on the right side when facing the control
1
/ in. per panel and (Circuit B) of the chiller. See Fig. 10-15, depending
8
on model. See Fig. 16-18 for accessory storage dimensions.
All sizes have Victaulic IPS connections as shown in the
As
physical data tables. The water connections are copper swaged
to Victaulic IPS. Any connecting pipe to the 30RAP unit must
be of a material that will not cause any galvanic corrosion. For
this reason, galvanized steel pipe or other dissimilar metals
must not be used unless joined by a dielectric coupling.
Provide a means of venting air from the high point of the
field-installed piping as required. Install field-supplied drains
in both the entering and leaving fluid connections.
After field piping is complete, freeze-up protection is rec-
ommended using inhibited ethylene glycol or other suitable in-
hibited antifreeze solution and electric heat tapes in areas
where piping is exposed to low ambient temperatures (34 F
[1° C] or below). Heat tapes should possess a rating for area
ambient temperatures and be covered with a suitable thickness
of closed-cell insulation. Route power for heating tapes from a
separately fused disconnect. Identify disconnect as heat tape
power source with a warning that power must not be turned off
except when unit is being serviced.
Installation of water systems should follow sound engineer-
ing practice as well as applicable local and industry standards.
Improperly designed or installed systems may cause unsatis-
factory operation and/or system failure. Consult a water treat-
ment specialist or appropriate literature for information regard-
ing filtration, water treatment, and control devices.
