Receiving the chiller
Inspection
Remove any transit packing. Inspect the unit to ensure that all components have been delivered
according to the bill of lading and that all miscellaneous boxes or materials have been received.
Ensure that no damage to any portion of the chiller or loose items has occurred during transit.
If any damage is evident, it must be noted on the carrier's freight bill and a claim entered in
accordance with the instructions given on the advice note.
Note:
•
Johnson Controls is not responsible for any damage in shipment or at job site or loss of
parts. Refer to Shipping Damage Claims Form (Form 50.15-NM).
•
For additional instructions regarding A2L refrigerants, refer to Chiller A2L Refrigerant
Application Data (Form 160.00-AD10).
Delivery and storage
To ensure consistent quality and maximum reliability, all units are tested and inspected before
leaving the factory. Units are shipped assembled, containing refrigerant under pressure. Units are
shipped without export crating unless crating has been specified on the sales order.
If the unit is put into storage, before installation, observe the following precautions:
•
Block the chiller so that the base cannot sag or bow.
•
Ensure that all openings, such as water connections, are securely capped.
•
Do not store in a location where exposed to ambient air temperatures exceeding 125°F (51.7°C)
for R-134a and 131°F (55.0°C) for R-1234ze.
•
The condensers must be covered to protect the coils and fins from potential damage and
corrosion, particularly where building work is in progress.
•
The unit must be stored 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. Follow all directions for long-term storage
requirements as defined in Long-Term Storage Requirement Field Preparation YVAM Air-Cooled
Chillers (Form 50.20-NM14).
The services of a qualified Johnson Controls service representative are required for the installation
and start-up of all YVAM model chillers installed in the continental United States.
Do not attempt to install or start the chiller without the presence of this qualified representative.
This may void all or portions of the chiller warranty.
The Johnson Controls warranty may be voided if the following restrictions are not adhered to.
•
Do not open valves or connections under any circumstances because such action will result in
loss of the factory refrigerant (Form 1) or nitrogen charge (Form 2).
•
Do not dismantle or open the chiller for any reason except under the supervision of a Johnson
Controls representative.
