To check the door seal, complete the following steps:
1. Open the door.
2. Insert a strip of paper (a couple of inches wide) between the door gasket
and the cabinet flange and close the door.
3. Slowly pull the paper strip from the outside. You should feel some
resistance.
4. Repeat this test at 4-inch intervals around the door. If the door does not
seal properly, replace the gasket.
In normal operation, the refrigeration system will produce a quantity of water
that is condensed out of the air and melted off during the defrost cycle. As
delivered, this unit routes the water to a stainless steel pan, where it will be
evaporated back into the room by compressor heat. An optional drain kit can
be installed to divert the water to a facility drain if desired.
This installation should only be performed by a qualified and properly
equipped service technician.
To install the optional drain kit:
1. Make sure that the rear breaker switch is turned to "OFF", the unit is
unplugged, and there is no power present.
2. Remove the sheet metal side cover on the latch side of the unit.
3. Place the small end of the tubing adapter into the tubing included in the
kit. A drop of liquid soap added to the fitting will enable the tubing to
slide on more easily.
4. Locate the clear/white plastic drain hose in the machine compartment.
Place the large end of the tubing adapter into the open end of the drain
hose.
5. Route the clear tubing out the grate on the rear of the unit to a suitable
facility drain. Ensure that the tube is not kinked or pinched and is
protected from traffic and other potential sources of damage. Keep the
tube at least 4 inches below the top of the unit's machine compartment
for the entirety of its run; rising above this level will cause water to back
up into the refrigerated compartment.
6. Replace all side covers and grates.
7. Start or restart the unit, following instructions in Section 7.2 .
