Fig. 3 Ð Refrigeration, Cycle

External Gear Lubrication Cycle (Refer to Item numbers shown in Fig. 5) Ð Oil reservoir is con- tained in the gear base. The external gear oil pump is mounted below the gear with the cooler/®lter. Oil is pumped through an oil cooler/®lter to remove heat and any foreign particles. A portion of the oil is directed to the gear bearings and gear mesh spray. The remainder is bypassed to the sump. The bear- ing and transmission oil returns directly to the reservoir to complete the cycle.

Oil may be charged into the external gear oil reservoir as described in the section, External Gear Pre-Start Checks, page 51. Observe the oil level in the oil level glass (Item 4) on the reservoir wall.

A motor driven oil pump (Item 10) discharges oil to the oil cooler/®lter (Item 12). The pump has an internal pressure regulator to protect the pump in the event of an obstruction downstream. Water ¯ow through the oil cooler is manually adjusted by a plug valve (Item 14) to maintain the oil at an operating temperature of approximately 130 F (54 C).

Upon leaving the cooler section (Item 13) of the oil cooler/ ®lter, the oil is ®ltered (Item 11) and is directed to the pres- sure control valve (Item 7). Before entering the pressure control valve, the oil pressure (Item 16) and temperature (Item 8) are monitored by the PIC.

A portion of the oil then lubricates the gear bearings (Item 2). Another portion is directed through an ori®ce (Item 5) to the gear mesh spray (Item 3) to lubricate the gear mesh (Item 1) during operation. Oil from both circuits re- turns by gravity to the reservoir.

STARTERS

All starters, whether supplied by Carrier or the customer, must meet Carrier Starter Speci®cation Z-375. This speci- ®cation can be obtained from a Carrier Sales Representa- tive. The purpose of this speci®cation is to ensure the com- patibility of the starter and the chiller. Many styles of compatible starters are available, including solid-state , auto-transformer, full-voltage, and, in the case of low-voltage main power sup- ply, wye-delta closed transition.
