7.4 WATER ACCUMULATION IN THE CABINET
Water accumulating in the cabinet is usually caused by
one of two things: condensation of moist air or rain water
leaking into the cabinet. Excessive condensation indicates
an air leak which allows moist outside air to continually
enter the cabinet and condense on the evaporator. To
minimize condensation on the evaporator:
1.
Make sure the refrigeration unit cover gasket is sealing
properly all the way around. In particular, check the
openings where the refrigeration lines and drain tube
pass through the cover. These openings should be
sealed completely around the lines and tube with duct
putty.
2.
Make sure the cabinet door is properly tightened when
it is closed so that it makes contact with the gasket on
all sides.
3.
Make sure there are no objects preventing the vend
door from closing. The vend door must open and close
freely and close completely.
Rain water can enter the cabinet through the rear
ventilation opening. Rain entering through this opening is
not considered hazardous since all components of the
refrigeration unit are sealed. Water will drain out through
the ventilation opening in the bottom of the cabinet. Check
to make sure the refrigeration unit cover gasket is seating
properly if excess water is noticed in the front of the
cabinet.
Some water accumulation on the inside bottom area of
the cabinet door is expected and should drain out on its
own. Check to make sure the rain guards on the top of the
door and cabinet are present and functioning properly to
minimize water coming in around the door gasket.
