MAINTENANCE ACCESS PANEL
If this unit is located in a sub-ceiling, an access panel should be installed in order to gain access to the
unit for routine maintenance. Common maintenance items are shown below for consideration when
designing panel size and location. A minimum panel size of 2' x 2' is recommended.
STEP 5: CONNECT DRAIN PIPE
The drain pipe is used to drain condensate water away from the unit. Improper installation may cause
leaks and unit or property damage.
1. Connect the drain pipe (field supplied) to the appropriate unit's connecting port using a metal
worm clamp. Make sure it is secured tightly and cannot be easily pulled loose.
2. Insulate the connecting port and pipe with the accessory sheath provided.
3. For gravity draining, install the drain pipe to the lower drain connecting port with a downward
slope of at least a 1/100 gradient to prevent water from flowing back into the unit. To keep the
drain pipe from sagging, install hanging wires every 39 - 59". Wrap the remaining indoor portion of
the drain pipe with foam pipe insulation to prevent condensation.
