3 TRANSPORTATION, RIGGING AND STORAGE

3.1 General

YR units are shipped as a single factory assembled,

piped, wired package, requiring minimum installation to

make chilled water connections, condenser water

connections, refrigerant atmospheric relief connections,

and electrical power connections.

Units can also be shipped dismantled when required by

rigging conditions, but generally it is more economical to

enlarge access openings to accommodate the factory

assembled unit. Units shipped dismantled MUST be

field assembled under the supervision of a York

representative.

FIELD ASSEMBLED UNITS ONLY

A York authorised representative must check the

installation, supervise the initial start-up and operation

of all newly installed units.

The York Warranty may be voided if the

following restrictions are not adhered to:

1. No valves or connections should be opened under

any circumstances because such action will result

in loss of the factory nitrogen charge.

2. Do not dismantle or open the unit for any reason

except under the supervision of a York

representative.

3. When units are shipped dismantled, notify the

nearest York office in ample time for a York

representative to supervise rigging the unit to its

operating position and the assembly of

components.

4. Do not make final power supply connections to the

compressor motor, solid state starter or control

panel.

5. Do not charge the compressor with oil.

6. Do not charge the unit with refrigerant.

7. Do not attempt to start the system.

8. Do not run hot water (40°C maximum.) or steam

through the evaporator or condenser at any time.
