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 40RM/RMS series units come with stub-out pipes for easy
refrigerant and chilled-water piping. These pipes are protruded
outside the units for ready installation. The standard location of
these pipes are at the right side. However, should alternate route of
pipings be required there are also available knock-out holes at the
opposite side of the unit.
Refrigerant Piping
See Tables 1A, 1B, 1D, 1E for refrigerant pipe connection sizes.
For ease in brazing, it is recommended that all internal and external
solder joints be made before unit is placed in final position.
The 40 RM direct-expansion coils have internal factory-installed
thermostatic expansion valves (TXV’s), distributors and nozzles for
use with R-22. Knock-outs are provided in the unit corner posts.
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 position of the suction line, outside
the unit. See Fig. 3.1 and 3.2.
40RM016-034 series evaporator have a face-split design. Ensure
that lower circuit of the coil is first on/last off when connected to the
condensing unit and /or system controls.
External TXV equalizer connections are provided and factory –
brazed into the coil suction manifolds.
If suction line must be horizontal, clamp bulb onto suction line at
least 45 degrees above the bottom at approximately the 4 o’clock
or 8 o’clock position. See Fig. 2.

connection it is recommended that all external fittings be made
before the unit is placed in a final position.
Alternative holes are available on the opposite Post Corner should
the alternate route of pipings are required. To design and install
chilled water piping, consult Carrier System Design Manual. See
Fig. 7 for an example of a typical installation. Recommended
fittings are listed in Table 1B.
To access 40RMS coil vents and drains, remove the unit side panel
over the coil header. Vent and drain plugs are on the top and
bottom of the header, respectively.
Fig. 5 – Condensate Drains
Condensate Drain
Install a trapped condensate drain line to unit connection as shown
in Fig. 5 . Some areas may require an adapter to connect to either
galvanized steel or copper pipe.
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 the 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

Fig. 12 - Fan Shaft Bearing
Individual Fan Wheel Adjustment
Loosen the two locking bolts holding the fan wheel hub to the shaft.
Position fan wheel in center of the fan housing and tighten locking
bolts. Clearance between wheel and housing should be the same
on both sides.
Fan Belts
Motor mounting plate and motor support angles are slotted to
permit both vertical and horizontal adjustments. Adjust belt(s) for
correct deflection by loosening motor mounting bolts, moving
motor/plate assembly forward or back and tightening bolts. Press
down on belt with one finger midway between fan and motor
pulleys to check deflection. For units with motor sizes up to and
including 3.0 hp (2.3Kw), correct deflection is 3/16 in. (4.8 mm). For
larger motor sizes, correct deflection is 1/8 in (3.2 mm). See Fig. 13
Fan Pulley Alignment
Align as follows :
1. Loosen setscrews on pulleys.
2. Align pulleys visually and tighten setscrews on fan pulleys to
lock it in place.
3. Use the methods shown in Fig. 15. To check proper pulley
alignment.
4. If pulleys are not in correct alignment, loosen the motor
holddown bolts and slide the motor axially until the pulleys are
aligned.
5. Tighten the motor holddown bolts.
Pulley and Drive Adjustments
To obtain desired fan speed, refer to fan motor and drive data and
adjust pulley as follows:
1. Remove belt from fan motor pulley after loosening motor from
motor base.
2. Loosen setscrew in moveable flange of pulley. Screw
moveable flange toward fixed flange to increase the fan speed
and away from fixed flange to reduce speed. Before tightening
setscrew, make certain that setscrew is over nearest flat
surface of pulley hub.
Fig. 13 - Fan Motor Mounting
If complete belt replacement is required during servicing , loosen
the motor plate mounting bolts, move motor/plate assembly
towards the fan pulley and pull the belt(s) off the pulleys. Reverse
the procedure with new bolts and readjust deflection.
Fan Rotation
Correct fan rotation with respect to fan outlet is shown in Fig. 14.
To reverse the direction of rotation of a 3-phase fan motor,
interchange any 2 of the power leads. Refer to the connection
Fig. 15 - Fan Pulley Adjustments
CAUTION
Increasing fan speed produces a greater load on motor. Do not
exceed rated capacity of motor.
Condensate Drains
Keep condensate drains free of dirt and foreign matter.
Return-Air Filters
Refer to Replacing Filters Section for filter accessibility and
removal. Replace with clean filters of the sizes listed in Tables 1A –
1D.
Coil Removal
Remove return-air filters. Remove any heavy dirt that may have
accumulated on underside of the coil. Coil can be cleaned more
easily with a stiff brush, vacuum cleaner or compressed air when
coil is dry. If coil is wet or if water is to be used for cleaning, guard
against splashing water on electrical components or damaging
surrounding area. Clean coil baffles as applicable and check for
tight fit to be sure air does not bypass coil.
Cleaning Insulation
The insulation contains an immobilized antimicrobial agent that
helps prevent the growth of bacteria and fungi. It is recommended
to clean the surface of the insulation after every cleaning of the coil
by wiping it with water-soap solution..
Replacing Filters
Filters can be removed and installed from either side of the unit.
1. Remove the filter side cover.
2. Remove old filters by sliding them out one by one from the
filter track.
3. Reverse the procedure to install new filters.
CAUTION
Do not operate unit without air filters.
*Motors are designed for satisfactory operation of nominal voltages
shown. Voltages should not exceed the limits shown in the Voltage
Limits column.
Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage
is greater than 2 %. Use the following formula to determine the
percentage of voltage imbalance.
% Voltage Imbalance
= max. voltage deviation from ave. voltage x 100
average voltage
Example:
Supply voltage : 230 – 3 – 60
Voltage Measurements:
Phase A-B = 226
Phase B-C = 233
Phase C-A = 228
Average Voltage = 226 + 233 + 228
3
Average Voltage = 229
Determine maximum deviation from average voltage.
(AB) 229 – 226 = 3
(BC) 233 – 229 = 4
(CA) 229 – 228 = 1
Maximum deviation is 4 V.
Determine % Voltage Imbalance.
= 100 x 4 / 229 = 1.75 %
This amount of phase imbalance is satisfactory as it is below the
maximum allowable 2%.
IMPORTANT
If the supply voltage phase imbalance is more than 2% at main
circuit breaker, contact your utility company.
