Observe the following precautions:
• Notify the nearest Quantech office in ample time
for a Quantech representative to observe rigging
the unit to its operating position and the assembly
of its components. Refer to the QWC4 Installation
Checklist (Form QWC4-CL1) for detailed instruc-
tions. Do not dismantle or unwrap the chiller for
any reason unless advised by a Quantech repre-
sentative.
• Do not make final power supply connections to
the compressor motor drive or control center.
• Do not open valves or connections under any cir-
cumstances.
• Do not charge the unit with refrigerant.
• Do not attempt to start the system.
• Do not run hot water (110°F/43°C max) or steam
through the evaporator or condenser at any time.
SHIPMENT AND STORAGE
To ensure consistent quality and maximum reliability,
all units are tested and inspected before leaving the fac-
tory. The chiller may be ordered and shipped in any of
the following forms:
• Form 1 (shipped assembled with refrigerant
charge)
•
Form 2
(shipped assembled without refrigerant
charge)
• Form 7 (shipped in split assemblies without re-
frigerant)
• Miscellaneous loose items are shipped with all
forms.
When shipping a Form 2 or Form 7 unit,
make arrangements with the nearest
Quantech Field Service Office to make
sure the refrigerant is on-site when the
unit is ready to be charged.
SECTION 3 - HANDLING, STORAGE, INSTALLATION, AND REASSEMBLY
Rigging and lifting should only be done by a professional rigger in accordance with a written rig-
ging and lifting plan. The most appropriate rigging and lifting method will depend on job specific
factors, such as the rigging equipment available and site needs. Therefore, a professional rigger
must determine the rigging and lifting method to be used, and it is beyond the scope of this manual
to specify rigging and lifting details.
