Safety
DANGER
• Please read these instructions completely before starting the installation or performing any service. Failure to follow the instructions and
safety precautions in this manual can result in serious injury or death.
• After installation, keep these instructions in a safe location for future reference.
• Electric supply must be identical in voltage, cycle, and phase to that specied on nameplate.
• Electrical supply must have Ground Fault Circuit Interrupter (GFCI) protection.
• A means for disconnecting electrical supply to the unit must be incorporated in the xed wiring in accordance with wiring rules. This is to
allow electrical disconnection of the unit from electrical supply after installation.
WARNING
• For use with clean, clear potable drinking water only. Do not use with water that is microbiologically unsafe or of unknown quality without
adequate disinfection before the system.
• Installation and connection to water and electrical mains must be in compliance with local and national laws.
• All Installation and Service work must be performed by an authorized service personnel.
CAUTION
• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory, or mental capabilities or
lack of experience and knowledge if they have been given supervision or instructions concerning use of the appliance in a safe way and
understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children
without supervision.
• To prevent a metallic taste or increased metal content in the water due to an electrolysis process caused by electrical feedback from the
grounding of electrical equipment to water supply and water waste mains, connect to these mains using non-conductive materials. The
provided non-metallic In-line Strainer meets this requirement.

Installation
For correct and safe installation, please read these instructions completely.
• All Installation work must be performed by an authorized service personnel.
• Disconnect electrical supply serving the Installation area to reduce risk of electrocution.
• Unit not suitable for installations where water jets could be used.
DANGER
WARNING
• Shut off water supply serving the Installation area to reduce risk of water damage.
• Ensure proper ventilation by maintaining clearance from cabinet louvers to wall on each side of Cooler as specied in Rough-In.
• Never wire compressor directly to electrical supply.
• Do not solder tubes inserted into the In-line Strainer as damage to the o-rings may result.
• Thoroughly ush all water lines and ttings of all foreign matter before connecting to Cooler.
• Warranty is void if the plumbing kit or glass ller is not specied for use by the Manufacturer for this particular model.
• Warranty is void if Installation is not made in accordance with current Manufacturing instructions.
CAUTION
• Hose-sets are not to be used for connecting to water mains.
• If inlet pressure is above 100 psig (0.69 MPa), a pressure regulator must be installed in water supply line. Any damage caused by
reason of connecting this product to water supply line pressure outside its rated pressure, is not covered by warranty.
• This cooler is manufactured in such a manner that it does not in any way cause taste, odor, color, or sediment problems. If a taste,
odor or sediment problem is prevalent, try installing our water lter on the supply line.
• Tools/Items required but not provided.

Service
For proper and safe servicing, please read these instructions completely.
• All Service and Maintenance must be performed by an authorized service personnel.
• Disconnect electrical supply to the unit before any service work to reduce risk of electrocution.
• Shut off water supply serving the unit before any service work to reduce risk of water damage.
DANGER
CAUTION
• Tools/Items required but not provided, for Servicing:
o Safety Glasses
o Protective gloves
o 5/16" (7.9mm) Hex Driver or Flathead Screwdriver
Service: Adjustments
1. Temperature Control: Factory set for 50ºF ± 5º (10ºC ± 2.8º) water under normal conditions. To adjust water temperature, remove front panel by
unscrewing (2) 5/16" (7.9mm) Hex Head screws. Set panel aside. Turn screw on cold control (Item 13) clockwise for colder, counter clockwise
for warmer. See Figure 9.
2. Water Stream Height: Stream height is factory set at 35 psig (0.24MPa). If supply varies greatly from this, remove items 1 and 2 and adjust
screw on item 4. Clockwise adjustmentwill raise stream height and counter-clockwise adjustment will lower stream. For best adjustment,
stream should hit basin approximately 6-1/2" (165mm) from bubbler. See Figure 5.
3. Water coming out of Bubbler continuously: When this occurs at the end of the compressor cycle, turn the cold control warmer (Item 13) counter-
clockwise 1/4 of a turn. See Figure 9.

Service: Inspection/Cleaning
• Inspect Cooler twice each year for proper operation and performance.
• Inspection of the unit will require disconnecting electrical supply, removal of panels, etc.
and reassembly and return to service practices.
1. Cleaning: Warm, soapy water or mild household cleaning products can be used to clean the exterior panels. Extra caution should be used to clean
the mirror nished stainless steel panels. They can be easily scratched and should only be cleaned with mild soap and water or Windex glass
cleaner and a clean, soft cloth. Use of harsh chemicals or petroleum based or abrasive cleaners will void the warranty.
2. Bubbler: Mineral deposits on the orice can cause water ow to spurt or not regulate. Mineral deposits may be removed from the orice with a
small round le not over 1/8” (3 mm) diameter or small diameter wire.
• CAUTION: DO NOT le or cut orice material. Care must be taken not to damage the orice(s)
3. Condenser Fan Motor: Conrm condenser fan turns freely. If the condenser fan does not spin freely, have an authorized service personnel
replace.
4. Ventilation: Cabinet louvers and condenser ns should be periodically cleaned with a brush, air hose or vacuum cleaner. Cleaning should be done
twice each year or more frequently if needed due to environment. Excess dirt or poor ventilation can cause no cold water and compressor cycling
on the compressor overload protector.
5. Water Flow: Conrm proper water ow. If water ow is slow, inspect lter or inline strainer for restriction. Replace lter cartridge if required.
Disassemble inline strainer and clean if required See Figure 6.
6. Lubrication: Motors are lifetime lubricated.
7. Actuation of Quick Connect Water Fittings: Cooler is provided with lead-free connectors which utilize o-ring water seal. To remove tubing from the
tting, relieve water pressure, push in on the gray collar before pulling on the tubing. To insert tubing, push tube straight into tting until it reaches
a positive stop, approximately 3/4” (19mm). See Figure 7.
Service: Inspection/Replacement
• Inspect Cooler twice each year for proper operation and performance.
• Inspection of the unit will require disconnecting electrical supply, removal of panels, etc. and reassembly and return to service practices.
1. Bubbler: To remove the bubbler, rst disconnect the electrical supply. Remove the Front Panel by removing (2) screws. To remove the bubbler,
loosen locknut from the underside of the basin and remove the tubing from the quick connect tting (see Figure 7 for actuation of Quick Connect
Fittings). When installing replacement bubbler, tighten nut only to hold parts snug in position. Do Not Overtighten. After servicing, replace the
front panel and two (2) screws.
2. Cleaning Strainer: Restricted water ow may be caused by clogged screen. Remove plug and screen. Clean screen and replace. Lubricate
O-Ring with food grade pharmaceutical mineral oil. Do not overtighten plug or ttings. See Figure 6.
