Thank you for purchasing the Crystal Mountain Crystal Pro Water Dispenser. The Crystal Pro brings a
fresh approach and a new look to point-of-use water dispensers. The system's contemporary color
scheme complements every oce environment. There are no bottles to change and the supply is virtu-
ally unlimited.
Hot, Cold & Ambient Dispenser
Your Crystal Pro Water Dispenser will provide up to 0.3 gallons (1.2 L) of hot water from a stainless steel
reservoir using a 450 watt heating element. A bi-metal limiter is provided to prevent overheating and
can be manually reset. The hot water is factory pre-set to 181°F (83 °C). Cold water is chilled with a high
capacity compressor using R134 refrigerant. An electro-mechanical thermostat controls the tempera-
ture of the water in the one gallon (3.8 L) stainless steel reservoir. The cold water temperature is facto-
ry preset to a nominal 41°F (5 °C)
UV Light System
All models of the Crystal Pro dispensers are tted with a UV-C band light system at the point of dispens-
ing and built into the ambient reservoir lid. This system is used to inhibit the growth of bacteria. When
dispensing Ambient or Cold water you will notice a pulsating “UV INSIDE” light which indicates the UV
light system activation.
Leak Detection System
All models of the Crystal Pro are tted with a leak detector. This system will generate an audible alarm
and front panel light alert upon detecting water in the base of the unit. In addition, the system will au-
tomatically shut o the incoming water supply to prevent further damage.
Filtration System (not included)
Crystal Pro dispensers are designed to be used with reverse osmosis, or carbon ltration. For locations
where a drain is not present, a ltration-only option is recommended.
Internal Storage Reservoir
An internal storage reservoir eliminates the need for an external storage tank. The internal compart-
ment is large enough to contain most water treatment systems. A oat mechanism guards against over-
ows.
Mechanical Components
All water connection ttings are compliant with NSF Standard 61. The Crystal Pro connects to the water
supply using a 1/4"female bulkhead tting. The molded panels are made from recyclable ABS plastic.

Installation

11
Installation
Make Water & Electrical Connections
1) The dispenser contains push-to-connect type ttings on the rear of the unit for the water supply and
R/O drain. These ttings accept ¼"polypropylene plastic tubing. If copper tubing is to be used,
these ttings must be replaced with a metal design. In addition, drain ports are provided for
the hot and cold tanks.
2) Connect a potable, cold water supply to the unit. Pressure must be 40-80psi (2.8-5.5 bar) and
at a temperature no more than 105°F (41°C).
3) Flush the water supply feed until it runs clear before making connection to the dispenser.
Caution:
Installation should only be executed by trained personnel. Check and follow the applicable plumbing
codes and ordinances when installing this equipment. The connection must be to the potable mains wa-
ter supply and should be via a shut o valve. An Appropriate anti-ood device should be tted as close-
ly as possible to the mains connection point. In order to meet plumbing regulations, a backow pre-
venter may be required.
Failure to use an appropriate anti-ood device for any reason will not obligate or make Crystal Moun-
tain responsible in any way for Product Liability issues relating to any claims, including water damage
claims.
Do not connect the dispenser to a water line which exceeds 105°F (41°C) as structural damage
may occur.
This water dispenser has a maximum pressure rating of 80 psi (5.5 bar). A pressure regulator must be
used for all installations. This will prevent internal structural damage to the unit and potential water
leaks. This should be installed on the water supply before the dispenser water inlet.
4) Plug the dispenser into the wall outlet and verify that the green power status indicator is “on.” A fuse
located on the rear service panel helps to protect the internal circuits from damage.
Caution:
Damage to the dispenser will result if hot and cold switches are turned on without water inside the
tanks.
If the unit was placed on its side, it must stand upright for a minimum of twenty-four hours before op-
eration to allow the compressor to stabilize.
Install Filtration (if applicable)
The Crystal Pro is shipped from the factory with no internal ltration installed.
Consult with your lter supplier on the best ltration solutions for the local water conditions and follow
the manufacturer's instructions on their installation, use and servicing.
Flush Filters (if applicable)
All lters must be ushed prior to use per manufacturer's instructions. Depending upon your ltration or
R/O system, this process may be combined with the initial sanitizing process. It is recommended to ush
no less than two gallons through each lter. If using R/O, check to see if the lter manufacturer/supplier
recommends soaking the R/O membrane (the R/O lter system is sold separately), prior to installation.
Dispose of the rst ve gallons of product water.

12
Installation
Sanitize the Dispenser
You must sanitize your system before using it for the rst time. Failure to do so may result in poor water
taste and water quality. This is best accomplished as outlined below.
1) Ensure both water connections – supply and R/O drain (if applicable) are made at the rear of the
unit.
2) Open top service panel to gain access to the main storage tank.
3) Open the ltration service panel.
4) Place a sanitization cartridge (this can be an empty lter cartridge or one supplied by your lter sup-
plier – not supplied with unit) inline before the water inlet of the unit.
5) Using a small eyedropper, prepare the sanitization cartridge by adding two teaspoons of unscented,
liquid chlorine bleach.
6) Insert this cartridge inline prior to the system. If you have empty sanitization cartridges, install them
in the lter positions. If you do not, remove your ltration system, then bypass it with a ¼' polyeth-
ylene tubing and two - ¼" union quick connect ttings. Refer to the service manual of the ltration
system being used for proper sanitization of your ltration system.
7) Slowly turn on the water supply until the main storage tank is ½ full then turn o.
8) Carry out a visual inspection for any water leaks.
9) Lift the main storage tank lid taking care not to damage the oat sensor or UV light.
10) Wearing sterile gloves, and using a clean, lint-free cloth thoroughly wipe down the inside of the main
storage tank with the bleach solution.
11) Let stand for ten minutes or until completely dry.
12) Slowly turn on the water supply.
13) Depress the dispensing buttons (alternate between hot, ambient and cold spigots) to allow the solu-
tion to run through the spigots and associated lines.
14) Drain the system until the chlorine bleach is no longer detected at the spigot. Drain the remaining
water through the drain connection at the rear of the unit.
15) Remove the sanitization cartridge and install the lter and/or R/O cartridges.
Note: Remember to connect the R/O drain line to the R/O cartridge. Ensure that the ow restric-
tor is visible inside the R/O drain line
Note: If R/O is being used, allow several hours to completely ll all tanks
The unit is supplied with a lter access door locking screw. This screw must be installed before
the unit is put into service.

13
Installation
Turn on “Hot” & “Cold” Power Switches.
1) With all tanks completely lled with water, both the hot and cold switches at the rear of the dispenser
should be turned “on.” It will take approximately twenty minutes for the hot water and two hours
for the cold water to reach their temperature presets.
2) Record the service date on the inside ltration panel for future reference. This will ensure that
maintenance intervals are recorded and scheduled.
3) Reinstall the ltration service panel.
