MAINTENANCE
General safety rules
Neglecting the condenser coil cleaning procedures WILL VOID YOUR WARRANTY
associated with the compressor or cost to replace the compressor!
Proper cleaning of stainless steel requires soft cloths or plastic souring
pads. Never use steel pads, wire brushes or scrapers!
Machine cleaning and maintenance routine
Cleaning solutions need to be alkaline or non-chloride cleaners. Any cleaner
containing chlorides will damage the protective film of the stainless steel.
Chlorides are also commonly found in hard water, salts, and household and
industrial cleaners. If cleaner containing chlorides are used be sure to rinse
repeatedly and dry thoroughly upon completion.
Routine cleaning of stainless steel can be done with soap and water. Extreme
stains or grease should be cleaned with a non-abrasive cleaner and plastic
scrub pad. There are also stainless steel cleaners available which can restore
and preserve the finish of the steels protective layer.
Never use and acid based cleaning solution! Many food products have an acidic
content which can deteriorate the finish. Be sure to clean the ALL food
products from any stainless steel surface. Common items include peppers,
tomatoes and other vegetables.
Cleaning the Condenser Coil
Disconnect machine. Remove front bottom panel and carefully slide out the
condensing unit. The condenser coil requires regular cleaning; recommended
every 30-60 days, depending of the accumulation of dust and grease. If the
buildup on the coil consists of only light dust and debris the condenser coil
can be cleaned with a simple brush. Heavier dust build up may require a vacuum
or even compressed air to blow though the condenser coil. If heavy grease is
present there are de-greasing agents available for refrigeration use and
specifically for the condenser coils. The condenser coil may require a spray
with the de-greasing agent and then blown through with compressed air.
Be sure all electrical and mechanical parts are dry before turning on the power.
Never use a high pressure water wash for this cleaning procedure as water can damage the electrical components located near or at the condenser coil. Do not place filter material in front of condenser coil. This material blocks air- flow to the coil similar to having a dirty coil!
If you keep the Condenser clean you will minimize your service expense and lower your electrical costs. Failure to maintain a clean condenser coil can initially cause high temperatures and excessive run times. Continuous operation with dirty or clogged condenser coils can result in compressor failures.
To put back the condensing unit in its place, slide in the unit carefully. BE SURE DRAIN PIPE IS LOCATED OVER THE PAN. Replace front bottom panel.
Cleaning the Gasket
Gaskets require regular cleaning to prevent mold and mildew build up and also
to keep the elasticity of the gasket. Gasket cleaning can be done with the use
of warm soapy water. Avoid full strength cleaning products on gaskets as this
can cause them to become brittle and prevent proper seals. Also, never use
sharp tools or knives to scrape or clean the gasket which could possibly tear
the gasket and rip the bellows.
Gaskets can easily be replaced and do not require the use of tools or
authorized service persons.
The gaskets can be pulled out of the grove in the door and new gaskets can be
“pressed” back into place.
Draining the Unit
Each unit has a drain located inside the unit which removes the condensation
from the evaporator coil and evaporates it at an external condensate
evaporator pan. Each drain can become loose or disconnected from moving or
bumping the drain.
IF YOU NOTICE EXCESSIVE WATER ACCUMULATION ON THE INSIDE OF THE UNIT be
sure the drain tube is connected from the evaporator housing to the condensate
evaporator drain pan.
IF WATER IS COLLECTED UNDERNEATH THE UNIT you may want to check the
condensate evaporator drain tube to be sure it is still located inside the
drain pan. The leveling of the unit is important as the units are designed to
drain properly when on a level surface, if your floor is not level this can
also cause drain problems. Be sure all drain lines are free of obstructions;
typically food product is found blocking drain lines causing water to back up
and overflow the drain pans.
Machine disposal
The product’s life-cycle is around 7 to 10 year from first use and operation
date.
This equipment is manufactured without dangerous or toxic materials. Some
parts of the equipments are biodegradable.
The disposing after the product’s life-cycle shall be determined by the
customer according to the rules and laws established in the city or State of
residence.
REMEMBER TO TAKE CARE OF THE ENVIRONMENT.
