ROUTINE MAINTENANCE: For all Models
Cleaning Your Dispenser
To optimize performance or when using dairy products, clean unit daily.
Regular cleaning of bowl components will result in maximum pumping efficiency, proper seating and sealing, and
prevention of leaks at the valve O-Ring and bowl gasket by removing dried-on beverage solids and pulp from mov-
ing sealed parts.
1. Wash all bowl components regularly. Follow all local health codes.
* Refer to Disassembly, Cleaning, and Assembly instructions on pages 4-6.
Sanitizing Your Dispenser
* Refer to Disassembly and Assembly instructions on pages 4-6.
1. In the bowl, mix one gallon of Oxford Chemical’s Disinfectant/Sanitizer Formula C or its equivalent.
2. Turn on spray motor(s) and allow sanitizer to spray around inside of bowl for a period of time as recommended by
the sanitizer manufacturer. Formula C is satisfactory for this purpose when mixed in a solution of 1 liquid ounce of
cleaner to 4 gallons of water. Run spray motor(s) for 60 seconds. In areas with extreme hard water, consult the
local health authority.
3. Drain sanitizer completely and thoroughly during each step of the cleaning process (wash, rinse, and sanitize).
Refer to tips on draining in Disassembly Guide on page 6.
HELPFUL HINTS
1. Noisy Impeller: Do not run impeller dry. The impeller will make a chattering sound in an empty bowl. Remove the
impeller and run a small amount of water in the bowl.
2. Valve and O-Ring: On the first installation, if there is an after-drip, place your hand on the valve and with a slight
downward pressure turn it slightly. This will help seat the o-ring so that it is properly aligned
with the valve seat. If an o-ring becomes cut or worn it should be replaced. If you are pumping
a product which has excessive pulp, a separate valve weight may be purchased to add extra
weight so the o-ring will press down against the pulp and guarantee a positive shut-off.
3. Valve Cap Use: The Valve Cap (Part # 2039) insures that a tight valve seal will occur with
products containing heavy pulp. The Valve Cap can be installed by placing it on top of the
Valve after the Valve has been assembled into the bowl. See Figure D.
4. High Water Marks on Bowl: When you agitate, you may get “high water marks” as the
beverage level drops. Keep the bowl as full as possible.
5. Spray or Agitate?: Most beverages can be sprayed. It is best not to spray iced tea,
iced coffee, natural juices, or beverages that foam (whipped drinks). A special agitator plate
(included) is used in place of a pump cover and spray tube to promote circulation.
6. Proper Cooling: Always keep spray switch on when refrigeration switch is on. A unit must
spray or agitate to cool. Failure to do this will cause impeller to lock-up. The dispenser is
designed to run 24 hours a day. Keep both spray and agitate on when beverage is in the bowls.
7. Condensation: Condensation on the bowls and lids is natural, cool, and refreshing. The amount of condensation
is affected by humidity. Condensation will run down the front panel into the drip tray. Remember to occasionally
empty the drip trays.
8. Single Bowl Operation: If you find it necessary to run your dispenser with only one bowl containing beverage,
put one half (1/2) cup of water in the unused cooling plate depression(s) for best one-bowl operation and
efficiency.

PREVENTATIVE MAINTENANCE
1) Wash all bowl components regularly.
2) Wash impeller and bearing sleeve individually and check for
wear.
a) Check for wear on bearing sleeve (flange should be
1.77mm thick - thickness of penny or quarter). (Figure F)
b) Check for wear on impeller (inner white center section
should be flush with colored part of impeller). (Figure E)
c) If bearing sleeve or impeller do not spin freely or are worn
- replace them. (Figure I)
d) Worn parts can cause personal injury, impair cooling and
can damage machine. (Figure G & H)
3) Check valve o-rings and bowl gaskets for wear or damage -
replace every 6 months or as needed.
4) Every 6 months or more often if needed: unplug unit, remove
panels, clean condenser and interior. (Remove dust and lint
from fins with a soft brush and vacuum.)
5) For further information, visit www.gmcw.com or
call [phone].
