RE: BevMax 4 Excessive Condensation Troubleshooting Tips
Reason: To provide troubleshooting tips for venders that exhibit symptoms of excessive condensation.
Things to do:
1. Is vender placed in a recommended environment for its use?
a. Indoor location, climate controlled?
b. Confirm vender is not placed in direct sunlight or near a heat source.
c. Confirm vender is level.
d. Vender is manufactured to function at 90° F, 65% RH. Conditions outside these parameters will produce
condensation that the vender may not be able to evaporate at a rate faster than it is produced.
2. Was the vender handled as recommended?
a. Moving the DN5800/DN3800 – due to the large size and weight of the Vender, never attempt to move the
Vender with a Hand Truck or Stair Climber. Use a pallet jack or Vender/Cooler Dollies at all times when
moving the Vender.
b. Casters on DN58/DN3800 - due to the large size and weight of the Vender, DO NOT USE casters.
c. Stacking the DN5800/DN3800 - due to the large size and weight of the Vender, DO NOT stack.
d. Due to weight, DN5800/DN3800 machine should never be moved loaded with product.

3. Identify where the vender is leaking and/or where condensation build up is accumulating if possible.
a. Is the condensation pan overflowing?
b. Is the evaporator drain pan over flowing?
i. Check drain trap from evaporator drain pan to condensation pan is not clogged.
c. Identify where the condensation is forming, look for air leaks in this area.
4. Check that Evaporator Fan is working in standard operating mode after 2 minute time out.

5. Condensation on glass door. IMPORTANT – Glass Door weighs approximately 57 lbs.
a. Check glass door gasket is sealing to cabinet using paper drag test.
b. Check glass door gasket is not damaged (cut, torn, rolled, etc).
c. Check XY components do not cause issues with gasket as door is opened & closed.
i. If issue with top hinge side of gasket hitting install new flat top hinge CR0014018 in place of original
hinge 65700036. Install and secure glass door. Check Glass Door Gasket Seal with paper drag
test.

ii. In venders serialized 913900068DH & higher if issue with bottom hinge side of gasket hitting install
service bottom glass door hinge 65700035. You will need to drill the existing bottom hinge pin hole
in the cabinet base larger to allow adjustment when you install the service hinge over top the existing
hole. A Unibit Step Drill is recommended when drilling the existing hole larger. Place the hinge
65700035 so it overlays the existing hole in the cabinet base. If it aligns exactly with the existing hole
you will need to place a thin spacer between the hinge and the front of the base plate. The spacers
approximate thickness is 1/16”. Use no more than 2 spacers or 1/8” as long as the glass door
frame is parallel to breaker strip and when you perform a paper drag test to confirm seal
before drilling holes. Mark and center punch the 2 hinge mounting holes. Drill these holes using a
7/32” (.219”) drill bit. Then drill the existing hinge pin hole in the cabinet base larger using the Unibit
Step Drill. You need enough clearance so the hole in the cabinet base will not touch the glass door
hinge pin, the glass door hinge pin will be located by the hole in the hinge that you are installing.
Secure the 65700035 hinge using two ¼ - 20 X 1 ¼” Self Tapping Type F Screws part #80030535.
Check hinge pin holes of hinge and cabinet base for proper clearance as noted earlier. Install and
secure glass door. Check Glass Door Gasket Seal with paper drag test.

6. Check the left side and top Security Angle seals to cabinet. The Security Angles have a bead of sealant applied to
the back before riveted in position to the Cabinet to eliminate air infiltration. If you can see light between the Security
Angle and Cabinet the seal has been broken. Look for loose rivets. You can run a bead of sealant to fill the gap
between the Security Angle and Cabinet to correct. Sealant from CMS is sold by the tube. Clear 90360049, black
90360048, or white 90360019.

infiltration around the Discharge Frame Assembly. Sealant from CMS is sold by the tube. Clear 90360049 or white
90360019.
8. Ensure all access holes from Service Area to Refrigerated Area have Perma Gum filling the holes on both sides to
prevent air infiltration.

the Base Panel Foam Assembly and the Base Panel Front Mounting Bracket from the left side all the way to the right
side. Sealant from CMS is sold by the tube. Clear 90360049 or white 90360019.
10. Check that the press stud on the bottom of the Refrigeration Systems Base Plate is in the guide slot in the Cabinet
Base. If it is not in the slot, it may cause the Refrigeration Unit to tip forward and not allow the condensation to drain
in to the Condensate Pan to evaporate.
