Delivery and storage
To ensure consistent quality and maximum reliability, all units are tested and inspected before
leaving the factory. Units are shipped completely assembled and containing refrigerant under
pressure. Units are shipped without export crating unless crating has been specified on the sales
order.
If the unit is being put into storage before installation, observe the following precautions:
• Block the chiller so that the base cannot sag or bow.
• Securely cap all openings, such as water connections.
• Do not store the chiller where it is exposed to high ambient air temperatures that may exceed
relief valve settings. Refer to Long-Term Storage Requirement - Field Preparation (Form 50.20-
NM7).
• Cover the condensers to protect the coils and fins from potential damage and corrosion,
particularly where building work is in progress.
• Store the unit in a location where there is minimal activity in order to limit the risk of accidental
physical damage.
• To prevent inadvertent operation of the pressure relief devices, do not steam clean the unit.
• Inspect the unit periodically during storage.
• Unit storage ambient temperature: -22°F to 125.6°F (-30°C to 52°C).
Inspecting the delivery
1. Remove any transit packing and inspect the unit to ensure that all components have been
delivered and that no damage has occurred during transit.
2. If there is any evident damage, note the damage on the carrier’s freight bill and enter a claim
in accordance with the instructions given on the advice note.
3. Report any major damage immediately to your local Johnson Controls representative.
