INSTALLATION
Installation Notice
A water filter is recommended for the water supply to the dispenser, especially in areas where water contains a
high level of minerals such as calcium or other solids. Over long periods of time, calcium deposits build on
heat-exchanger coils and will lower the cooling capacity of the system. Calcium build up will also occur on the
strainers enclosed in the dispensing valves.
The cooling system is provided with copper coils, designed to last the life of the dispenser. However, some
chemicals in treated or not treated water, specifically chlorine and sulfur (sulfide) may shorten the life of the coils.
The initial investment in the filtering system will pay for itself in quality and by ensuring longer life for the
machine.
Unpacking
1. 
With the unit upright, remove staples from the box at the very bottom around perimeter of the box and on the 
top of the box.
2.
Open the top of the box and remove the accessory box.
3.
Slide the box tube upward exposing the machine.
4. 
Remove supporting corners and front supporting block.
5.
The unit must have the legs installed upon removal from the packaging.  Legs are supplied in the acces-
sory kit (box on top of the machine in the packaging.)
Failure to install the legs will cause the dispenser refrigeration system to work improperly and burn out as
well as possibly damage the water inlet valve.
6.
Support all 4 sides, lift and place in an appropriate area. (See location below)
Installing Your Unit
1. 
Location
Position dispenser in a well-ventilated area indoors. Avoid exposure to direct sunlight and/or heat caused 
by radiation. Ambient room temperature must be in the range of 60Þ - 90ÞF (15-32ÞC). Do not install unit
in an enclosed area where heat build up could be a problem.
Note: Air flow direction and spacing required on Figure B page 4.
2.
Plumbing
Connect the dispenser to cold, potable water source suitable for drinking.
Do not install unit on a water softener/softening line. For proper operation incoming supply water pressure
must be in the range 29 psig (2 - 2.75 bar), therefore a water pressure regulating valve is recommended. 
3.
Electrical
This unit is supplied with a 6” (2m) long 2 wire plus ground power cord. The PM45-B connector is suitable
for standard single phase 220V/50Hz power supply. PM4-B models should be connected to a 115V 60 Hz
power supply. This cord exits the unit out the bottom of the base and should be routed per National Electric
Code.

CAUTION:
DO NOT ALTER OR DEFORM THE PLUG IN ANY WAY!
ALTERING OR DEFORMING THE PLUG MAY DAMAGE UNIT AND WILL VOID WARRANTY!
