Unit Positioning -- The unit can be mounted on the floor for
vertical application with return air entering the face of the
unit and supply air discharging vertically through the top of
the unit. The unit can also be applied in a horizontal
arrangement with return air entering horizontally and the
supply air discharging horizontally. When applying the unit
in a horizontal arrangement, ensure the condensate drain pan
is located at the bottom center of the unit for adequate
condensate disposal. See Fig. 6 for condensate connections
for each unit position.

IMPORTANT: Do NOT attempt to install unit with return
air entering top panel of unit. Condensate will not drain from
unit.

Typical positioning and alternate return air locations are
shown in Fig. 6. Alternate return air locations can be used
by moving the unit panel from the alternate return air
location to the standard return air location. Refer to overhead
suspension accessory drawing (Fig. 7) for preferred
suspension technique. The unit needs support underneath to

40RU

prevent sagging.

Unit Isolation -- Where extremely quiet operation is
essential, install isolators between floor and base of unit,
or between ceiling and top section of unit.

Be sure that unit is level and adequately supported. Use
channels at front and sides of unit for reference points
when leveling.

Refrigerant and Chilled Water Piping Access -- The
40RU Series units come with standard knockouts for
refrigerant and chilled water piping. These knockouts are
located on both sides of the unit for installation flexibility.
The standard knockouts provide sufficient access to the
unit’s coils for all 40RUA*07, 08, 12, 14, 16 and
40RUQ*07, 08, 12 units. 40RUQ*16 units, as well as
40RUS*08, 12, 14, and 16 units require additional holes
which must be field--fabricated to accommodate the
piping. See Fig. 8 for positions and dimensions of the
additional access holes required for the 40RUQ*16 and
40RUS units. Recommended access hole use is also listed
for all units. Note that Fig. 8 shows the access holes on
the control--box side of the unit; this is the side of the unit
with the coil headers, so it is used most often for piping
access.

IMPORTANT: Do not bury refrigerant piping underground.
Refrigerant Piping -- See Tables 1A–1F for refrigerant

pipe connection sizes. For ease in brazing, it is
recommended that all internal solder joints be made
before unit is placed in final position.

The 40RU direct--expansion units have internal
factory--installed thermostatic expansion valves (TXVs),
distributors, and nozzles for use with R--410A. See Table 2
for part numbers. Knockouts are provided in the unit corner
posts for 40RU refrigerant piping. See Fig. 8, which also
lists recommended knockouts and access holes to use for
each 40RU unit size. Recommended fittings are listed in
Tabl e 3.

The sensor bulb capillary tubes must be routed from the
TXVs inside the unit through one of the piping access
holes. Clamp the TXV sensor bulb on a vertical portion of
the suction line, outside the unit. See Fig. 9.

NOTE: Be sure to remove the styrofoam shipping pad
from the TXV. Verify that it has been removed. See Fig. 5.

IMPORTANT: Never attach the sensor to the suction
manifold. Do NOT mount the sensor on a trapped portion
of the suction line.

The 40RU Series evaporator coils have a face--split design.
Ensure that lower circuit of coil is first on/last off when
connected to the condensing unit and/or system controls. See
Fig. 10.

External TXV equalizer connections are provided and
factory--brazed into the coil suction manifolds.

If suction line must be horizontal, clamp bulb to suction
line at least 45 degrees above bottom, at approximately
the 4 o’clock or 8 o’clock position. See Fig.11.

Fig. 14 -- Drain Pan Slope Adjustment

As shipped, the unit’s condensate drain pan is NOT sloped
towards the drain connection. The pan slope must be
changed to pitch towards the side of the unit with the
drain connection. See Fig. 14. Loosen the 2 screws next to
the drain outlet at both ends of the unit, push drain pan
down in the slots near the drain connection, and up in the
slots on the opposite end. Re--tighten screws. The pan

toward the drain connection.
Fan Motor and Drives -- Motor and drive packages are

factory installed in all units. The motor and drive
packages consist of the following items:

NOTE: A trap must be installed in the condensate drain
line to ensure that the static pressure of fans is balanced with
the water column in the drain line and that condensate can
drain completely from pan. Without a trap, air can be drawn
up drain line until water level in condensate pan becomes
equal to static pressure created by fans, preventing complete
drainage. Conditions will worsen as filters become dirty.

Motors are designed for satisfactory operation within 10% of
normal voltage shown. Voltages should not exceed the limits
shown in the Voltage Limits column.

NOTES:

1. Minimum circuit amps (MCA) and MOCP values are calcu­lated in accordance with The NEC. Article 440.

2. Motor FLA values are established in accordance with Under­writers’ Laboratories (UL). Standard 1995.

3. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply
voltage is greater than 2%. Use the formula in the example
(see column to the right) to determine the percentage of volt­age imbalance.

4. Installation with Accessory Electric Heaters
Size the Field Power Wiring between the heater TB1 and the
40RU indoor fan motor per NEC Article 430 ---28 (1) or (2)
(depends on length of conduit between heater enclosure and
40RU power entry location). Install wires in field ---installed

Before performing service or maintenance operations
on unit, always turn off main power switch to unit and
install lockout tag. Unit may have more than one
power switch.

Adjusting TXV for Superheat

(40RUA and RUQ only) —

The unit--mounted thermostatic expansion valve(s) is/are
factory set to provided superheat at the bulb location in
10_Fto15_F (5.5_Cto8.3_C) range. Actual system load
conditions may require adjustment of the factory setting.
To adjust the TXV superheat setting:

1. Remove the seal cap from the bottom of the TXV
body.

Most unit service can be performed by removing one or
both of the unit’s side panels. Coil cleaning or removal or
insulation cleaning may require removal of a rear, top, or
bottom panel, depending on the unit’s orientation. When
service is completed, replace unit panels.

Panels -- Panels are fastened to unit frame with sheet metal
screws. Fan and coil compartment must be sealed tightly
after service to prevent air from bypassing the cooling coil.

Fan Motor Lubrication -- Fan motor supplied with unit is
permanently lubricated and requires no further lubrication.

23

Fan Shaft Bearings -- Bearings on size 07--12 units are
sealed, permanently lubricated bearings that require no
further lubrication. Size 14--16 units have pillow--block
bearings (Fig. 23) that must be lubricated with suitable
bearing grease approximately every 3 months. See Table 7
for suitable lubricants.

Centering Fan Wheel -- If fan and fan shaft assembly are
not properly centered, blades may scrape against the
blower side scroll plate or may create an objectionable
whistling noise. It may be necessary to adjust individual
fan wheels or move entire fan shaft. See the following two
sections.

If complete belt replacement is required during servicing,
loosen the motor plate mounting bolts (Fig. 25), move
motor/plate assembly towards fan pulley, and pull belt(s)
off pulleys. Reverse the procedure with new bolts and
readjust deflection.

Fan Rotation -- Correct fan rotation with respect to fan
outlet is shown in Fig. 26.

To reverse the direction of rotation of a 3--phase fan
motor, reverse any 2 of the power leads. Refer to the
connection diagram on the inside of motor terminal box
cover for proper reversing procedure of single--phase
