Service
For proper and safe servicing, please read these instructions completely.
DANGER
• 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.
CAUTION
• Tools/Items required but not provided, for Servicing:
o Safety Glasses
o Protective gloves
o Hex drives.
Service: Adjustments
1. Temperature Control: Factory set for 50ºF ± 5º (10ºC ± 5º) water under normal conditions. To adjust water temperature, turn screw on Item
No. 13 clockwise for colder, counter clockwise for warmer.
2.
Water Stream Height: Stream height is factory set at 35 psig (0.24 MPa). If supply pressure varies greatly from this, adjust screw located on
the right knee clearance area side at bottom of the switch shroud. Clockwise adjustment will raise stream and Counterclockwise adjustment
will lower stream. For best adjustment, stream should hit basin approximately 6-1/2” (165mm) from bubbler on the downward slope of the basin.
3.
Water coming out of Bubbler continuously: When this occurs at the end of the compressor cycle, turn the cold control warmer
(counterclockwise) ¼ turn.
Service: Inspection/Cleaning
• Inspect Bottle Filler and 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 finished 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 orifice can cause water flow to spurt or not regulate. Mineral deposits may be removed from the orifice with
a small round file not over 1/8” (3 mm) diameter or small diameter wire.
• CAUTION: DO NOT file or cut orifice material. Care must be taken not to damage the orifice(s)
3.
Condenser Fan Motor: Confirm condenser fan turns freely. If the condenser fan does not spin freely, have an authorized service personnel
replace.
4. Ventilation
: Cabinet louvers and condenser fins 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: Confirm proper water flow. If water flow is slow, inspect filter or inline strainer for restriction. Replace filter cartridge if required.
Disassemble inline strainer and clean if required.
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 fitting, relieve water pressure, push in on the gray collar before pulling
on the tubing. To insert tubing, push tube straight into fitting until it reaches a
positive stop, approximately 3/4” (19mm).
