UNPACKING THE DEHUMIDIFIER
Use the cutline on the carton to pull carton off dehumidifier.
INCLUDED IN THE CARTON
• Dehumidifier
• Installation manual
• 3/4" (DN20) P-Trap
• 3/4" MNPT x 3/4" (DN20 x 20 mm) female pipe
• 3/4" x 3/4" x 3/4" (DN20 x DN20 x DN20) T-fitting
• 30 feet of thermostat cable
• MERV 11 filter
• Hanging brackets
• Model D77 control (ships separately, if selected)
LOCATION CONSIDERATIONS
This unit is not to be accessible to the general public. The dehumidifiers should
be spaced evenly throughout the area to be dehumidified with the following
recommendations:
1. Avoid placement where the discharge of one dehumidifier is pointing
toward the inlet of another.
2. Avoid locating the dehumidifier inlet too near a supply register. Space is
not usually available to totally avoid this, but minimizing the amount of
cold air that is discharged to the dehumidifier inlet will improve moisture
removal performance of the dehumidifier.
3. Account for handling dehumidifier condensate by considering drain or
condensate pump locations.
4. Leave 18" (457 mm) minimum clearance for access to the user interface,
electrical panel for service and filter for maintenance. See Figure 7-1.

INSTALL BRACKETS FOR SUSPENDING UNIT
The brackets are designed to accommodate up to 1/2" threaded rod.
1. Insert bracket into slots on the base. See Figure 8-1.
2. Rotate the bracket up toward the dehumidifier and secure the bracket to
the side of the dehumidifier using #12 sheet metal screws (provided). This
can be done with a 5/16" hex socket. See Figure 8-2.
3. Repeat for remaining three brackets.

HANGING THE DEHUMIDIFIER
Use the threaded rod to suspend the unit from appropriate
ceiling structure. The unit weight is 180 lbs. Install
vibration isolators if located in an area where noise could
be a concern. Level unit right to left and front to back so
that unit drains properly. See Figure 8-3.

FIGURE 9-1: FLOOR MOUNTING USING LEVELING FEET KIT (PART #: 601175)
FLOOR MOUNTING
The leveling feet kit (not included) is required for floor mounting. The drain
hose/pipe must continuously slope downward toward the drain. Use solid
supports as needed to elevate the unit enough to allow for continuous drain
slope. Use the adjustable feet to level the unit right to left and front to back so
that unit drains properly.
1. Insert nut into the bracket on the dehumidifier.
2. Thread leveling foot into nut to desired height.
3. Lock into place by tightening jam nut.

P-TRAP (INCLUDED)
The blower draws air through the dehumidifier, putting the cabinet under
negative pressure. As a result, the included P-trap is required for proper
draining. The installed drain fitting on the dehumidifier is 3/4" (DN20) FNPT.
Use the included fittings to trap and install the drain. See Figure 10-1. The
drain tubing can be hard pipe or flexible tubing. NOTE: PTFE thread seal tape
is recommended for the threaded connections and hand tighten only. Use PVC
primer and cement for all slip fit connections to prevent leaks. After installing
the drain connections, trap, and tubing, pour enough water, about 32 oz.
(950 mL) into the dehumidifier drain pan to prime the trap.
If the drain tubing will be installed to a condensate pump, or if a common
drain tube will serve multiple dehumidifiers or air conditioners, a vacuum
breaker is recommended to prevent the p-trap from being unintentionally
siphoned. Install a T-fitting with a short section of drain tubing pointed vertically
and extending above the start of the filter (see Figure 10-1). Install the
vacuum breaker after the P-trap.
