PRE-INSTALLATION

Omnizone 50BV units are intended for indoor installation only.
™
Review unit dimensions, piping and wiring connections, service
clearances, and other equipment details included in this installa-
tion guide, the product data, or the unit submittal prior to
equipment installation.

Inspection

Upon receipt of shipment, carefully check the shipment against
the bill of lading. Single piece units ship as a complete assembly.
Modular units ship as either one (30 ton low boy), two (30 ton
high boy, 40-60 ton low boy), or four (40-60 ton high boy) sepa-
rate pieces. Make sure all pieces have been received. Inspect the
carton or crating of each unit, and inspect each unit for damage on
both the interior and exterior. Ensure the shipping company makes
proper notation of any shortages or damage on all copies of the
freight bill. Concealed damage not discovered during unloading
must be reported to the shipping company within 5 days of re-
ceipt of shipment.
NOTE: It is the responsibility of the purchaser to file all necessary
claims with the shipping company.

UNIT STORAGE

The 50BV units are designed and packaged for indoor storage and
use only. If the equipment is not needed for immediate installation
upon its arrival at the job site, it should be left in its shipping
carton and stored in a clean, dry area. Units should not be stored in
a location that is subject to freezing. Units must only be stored or
moved in the normal upright position, as indicated by the up
arrows on each carton, at all times. DO NOT STACK UNITS.

INSTALLATION

Step 1 — Check Jobsite
Prior to proceeding with removal of existing equipment and/or
installation of new equipment, verify the following:
1. Be sure that the location chosen for unit installation provides
ambient temperatures maintained above freezing.
2. Be sure the installation location is isolated from sleeping
areas, private offices and other acoustically sensitive spaces.
3. Be sure unit is mounted at a height sufficient to provide an
adequate slope of the condensate lines. If an appropriate slope
cannot be achieved, a field-supplied condensate pump may
be required.
4. On horizontal units, allow adequate room below the unit for
condensate drain trap and do not locate the unit above supply
piping.
5. Provide sufficient space for duct connection. Do not allow the
weight of the ductwork to rest on the unit.
6. Provide adequate clearance for filter replacement and drain
pan cleaning. Do not allow piping, conduit, etc. to block filter
access.
7. Provide sufficient access to allow maintenance and servicing
of the blower and blower motor, compressor, refrigerant
circuit, controls, and coils.
8. For units with free return (non-ducted), provide adequate
space for proper return airflow. For units installed in closets
or mechanical rooms, provide sufficient return grill area for
proper airflow.
9. Provide ready access to water valves and fittings, and
screwdriver access to unit side panels, discharge collar, and
all electrical connections.
10. Where access to side panels is limited, pre-removal of the
control box side mounting screws may be necessary for
future servicing.
11. For units that are installed in enclosed spaces (such as
furred-in closets or behind finished ceilings), provide access
panels to allow for the installation, maintenance, service, and
removal of the unit.
12. For CV/SAV applications verify that the proper thermostat or
third-party DDC exists for unit operation.
13. For VAV applications, verify that VAV air terminal units have
been installed or will be installed prior to starting up the unit.
Also verify that a control interface will be available.
If any of the above items are missing or incorrect, contact your
local Carrier equipment sales office.
IMPORTANT: It is the installing contractor's responsibility to
ensure that all equipment is installed with proper access for
service, start-up, installation of accessories, configuration of con-
trol and other components, and equipment removal in accor-
dance with Carrier's recommended service clearances and instal-
lation instructions. Please refer to the Carrier Commercial
WSHP Warranty Statement (document number 04-570008-01)
for details on warranty exclusions regarding equipment, access,
removal and clearances.
Step 2 — Check Unit
Upon receipt of equipment at the job site, inspect the carton or
crating of each unit, and inspect each unit for damage on both the
interior and exterior. Note any damage and contact your local
Carrier equipment sales office.
To prepare the unit for installation, complete the procedures listed
below:
1. Verify that the correct unit has been received. Check the unit
capacity (tonnage), voltage, orientation, and configuration.
2. Compare the electrical data on the unit nameplate to verify
the jobsite power feed (voltage, amperage, MCA) and power
protection (MOCP).
3. Verify that the unit is the correct model for the entering water
temperature of the job (standard or extended range).
4. Remove the unit packaging, keeping the unit attached to the
shipping pallet. Do not destroy packaging. Save for
re-installation on the unit if the unit will not be fully installed.
5. Open the unit access panel. Verify that the refrigerant tubing
is free of kinks or dents, and that it does not touch other unit
components.
6. Check the water piping and piping connections to make sure
they are free from defects, kinks, dents, and appear to be
water tight. Verify system operating water pressure.
7. Inspect the blower assembly. Verify that the blower has not
come lose during shipping. Verify clearance between the
blower wheel and the blower housing. Verify free blower
rotation.
8. Inspect all electrical connections. Be sure connections are
clean and tight at the terminals.
9. Check unit controls. If a CV unit, verify a thermostat or DDC
control is available to control the unit. If a VAV unit, verify
proper sensors have been provided and a commissioning
interface will be available.
10. Remove any shipping brackets from the unit.
11. If a modular unit, verify all modules/pieces have been
received.
