PRE--INSTALLATION
1. The power supply (v, ph, and Hz) must correspond to
that specified on unit rating plate.
2. The electrical supply provided by the utility must be
sufficient to handle load imposed by this unit.
3. Refer to Installation, General section (page 2) and
Fig. 1 and Fig. 2 for locations of electrical inlets, con-
densate drain, duct connections, and required clear-
ances before setting unit in place.
4. This installation must conform with local building
codes and with the NEC (National Electrical Code) or
ANSI (American National Standards Institute)/NFPA
(National Fire Protection Association) latest revision.
Refer to provincial and local plumbing or wastewater
codes and other applicable local codes.
Moving and Storage -- To transfer unit from truck to
storage site, use a fork truck. Do not stack units more than
2 high during storage. If unit is to be stored for more than
2 weeks before installation, choose a level, dry storage
site free from vibration. Do not remove plastic wrap or
skid from unit until final installation.
Rigging -- All 40RU Series units can be rigged by using
the shipping skid. Units are shipped fully assembled. Do
not remove shipping skids or protective covering until unit
is ready for final placement; damage to bottom panels can
result. Use slings and spreader bars as applicable to lift
unit.
INSTALLATION
General -- Allow the following clearances for service
access and airflow:
SRear: 3 ft (914 mm) [21/2ft (762 mm) with electric heat
accessory]
SFront: 21/2ft (762 mm)
SRight Side: 31/2ft (1067 mm)
SLeft Side: 21/2ft (762 mm)
For units equipped with an economizer, refer to the
accessory installation instructions for additional clearance
requirements. Be sure floor, wall, or ceiling can support
unit weight (Tables 1A – 1F). See Fig. 1 and Fig. 2 for
dimensions.
Uncrating -- Move unit as near as possible to final
location before removing shipping skid.
Remove metal banding, top skid, and plastic wrap.
Examine unit for shipping damage. If shipping damage is
evident, file claim with transportation agency. Remove
base skid just prior to actual installation.
Check nameplate information against available power
supply and model number description in Fig. 3.
NOTE: Be sure to remove the styrofoam shipping pad
from the thermostatic expansion valve (TXV). Verify that
it has been removed. See Fig. 5.

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
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
Table 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.

3” MIN.
[76]
NOTE: Dimensions in [ ] are in millimeters
C10691
Fig. 13 -- Condensate Drains
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.
Install clean--out plugs in trap. Pitch drain line downward
to an open floor drain or sump. Provide service clearance
around drain line to permit removal of unit panels.
Observe all local sanitary codes.
C10692
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
should have a pitch of at least 1/4--in. over its length
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:
1 — fan motor
1 — adjustable motor pulley
1—fanpulley
1—fanbelt
(40RUA*07--12, 40RUQ*07--12, 40RUS*08--12 units)
2 — matched fan belts
(40RUA*14--16, 40RUQ*16, 40RUS*14--16 units)
For instructions on changing fan rotation, changing drive
speeds and adjusting drives, see Pulley and Drive
Adjustment in the Service section.

Power Supply and Wiring -- Check the unit data plate to
ensure that available power supply matches electrical
characteristics of the unit. Provide a disconnect switch
with an integrated lock--out feature of size required to
provide adequate fan motor starting current. See Tables
4--6 for unit electrical data.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Do not use gas piping as an electrical ground. Unit
cabinet must have an uninterrupted, unbroken electrical
ground to minimize the possibility of personal injury if
an electrical fault should occur. This ground may consist
of electrical wire connected to unit ground lug in control
compartment, or conduit approved for electrical ground
when installed in accordance with NEC (National
Electrical Code); ANSI/NFPA 70, latest edition (in
Canada, Canadian Electrical Code CSA [Canadian
Standards Association] C22.1), and local electrical
codes.
!WARNING
FIRE HAZARD
Failure to follow this warning could result in intermittent
operation or performance satisfaction.
Do not connect aluminum wire between disconnect
