The inlet and outlet water connections for the water-cooled system are located on the top of each refrigeration system as
shown in Figure 5. The connections are 0.5 in. FPT.
To allow for movement of the equipment during servicing, FARRAR recommends using 0.5 in. industrial grade flexible hose, 8
ft. (2.5 m) in length. An adapter from imperial to metric is included for each fitting.
FARRAR strongly recommends installing a 0.5-in. ball valve at the water inlet, along with a strainer and pressure gauge, as
shown in Figure 6. These will facilitate any servicing or testing requirements.
Check all connections for leaks. Verify that the water differential pressure is adequate along with nominal flow and tempera-
ture requirements (see Specifications in this manual).
Optional drain pan assembly for +2°C to +8°C operation and -20°C operation.
For units that operate in unconditioned facilities, it is recommended that the drain line be piped to a facility drain for proper
operation of the unit.
