Piping and Drain Connections.
See Figures 1-1 to 1-8 and 3-11 to 3-17 for connection locations.
When connecting refrigeration piping, you must follow and adhere to all piping codes required in the
jurisdiction of installation. Vogt recommends ASHRAE 15 “Safety Standard for Refrigeration
Systems,” and ASME B31.5 “Refrigeration Piping and Heat Transfer Components,” which are
required in many locations throughout the world. Make sure all piping is kept clean, dry and
contaminate free. All piping should be supported properly.
! CAUTION !
Exterior shut-off valves must be provided in the water
inlet lines. The minimum inlet water pressure for
satisfactory operation of the machine is 40 psig.
The maximum allowable pressure is 100 psig.

Make-Up Water In.
The water required for ice making must be potable water, safe for human
consumption, and should be of the highest quality available. The best way to determine water
quality is to have a complete water quality analysis by a qualified laboratory.
It is advisable to install a particle filter in the make-up and flushing water lines to trap dirt, sand, rust,
or other solid particles prior to entering the water tank and contaminating the ice. Be sure to size the
filter large enough to meet the water demands of 15 GPM (peak flow), allowing for a restriction
through the filter as it traps these particles. The inlet water pressure should be a minimum of 40 psi.
Refer to Table 3-1 for line size and Chapter 11 for average flow rate at various water temperatures.
Flushing Water In.
Flushing water (blowdown) is necessary to melt ice fines and to flush dissolved
solids from the water tank during the thawing (harvest) cycle. This function is important and helps
to maintain good ice quality. If water quality is superior, this blowdown can be reduced by installing
a smaller orifice in the flushing outlet elbow. Make sure there is enough flushing water to prevent
the accumulation of excessive ice fines and dissolved solids in the tank.
If make-up and flushing water are from the same source, they can be connected by a common line to
the machine.
