Guide specifications (cont)

12.Compressor Suction Service Valve:

Standard refrigerant discharge isolation and liquid valves enable service personnel to store the refrigerant charge in the evaporator or condenser during servicing. This factory- installed option allows for further isolation of the compressor from the evaporator vessel.

13.GFI Convenience Outlet:

Shall be factory or field-installed and mounted with easily accessible 115-v female receptacle. Shall include 4 amp GFI receptacle.

14.300 psig (2068 kPa) Evaporator Operating Pressure:

This option shall provide for water-side pres- sure operation up to 300 psig (2068 kPa).

15.300 psig (2068 kPa) Condenser Operating Pressure:

This option shall provide for water-side pres- sure operation up to 300 psig (2068 kPa).

16.Marine Waterboxes:

Marine waterboxes shall provide water piping connections extending from the side of the waterbox (as opposed to extending from the end of the waterbox). This option also includes a removable bolt on waterbox cover allowing access to the heat exchanger tubes without breaking the existing field piping. This option is available for both the evaporator and condenser.

17.Flanged Connection:

The flanged connection option shall provide an ANSI flange on the end of the chiller water piping for connection to a customer supplied mating flange in the field piping. This option is available for both the evaporator and condenser.

18.One-Pass Condenser:

This option shall provide a lower pressure drop through the condenser for applications with low delta T (temperature) or high flow or where the condensers are piped in a series. The one-pass condenser option is only avail- able with flanged connections and with a dis- charge end leaving water connection.

19.Dual Point Power:

The dual point power option shall provide a means for connecting two sources of power to dual compressor chillers. One source of power is wired to operate the compressor on the A circuit and one source of power is wired to operate the compressor on the B circuit of the chiller.

20.Non-Fused Disconnect:

This option shall provide a no load, lockable, through the door handle disconnect for unit power on the chiller. On dual point power, one disconnect is provided for each of the two main power supplies. This disconnect does not remove the control circuit from power supply.

21.Control Transformer:

The control transformer shall be sized to sup- ply the needs of the control circuit from the main power supply.

22.Nitrogen Charge:

A nitrogen charge option is available to pro- vide a 15 lb (6.8 kg) charge of nitrogen instead of a full factory charge of R-134a refrigerant to keep the chiller refrigerant cir- cuit dry during shipment. This option is rec- ommended for applications where the unit will be disassembled prior to installation. Units shipped with a nitrogen charge will receive an electrical continuity test at the factory prior to shipment.

23.Crate for Shipment:

This option is recommended for export orders. The chiller will be bagged prior to being placed in a wooden crate.

24.Remote Enhanced Display:

This option is a remotely mounted indoor 40-character per line, 16-line display panel for unit monitoring and diagnostics.

25.Vibration Springs:

A set of non-siesmic spring isolators can be provided for installation at the jobsite.
