FOREWORD
Congratulations on purchasing the MovinCool air conditioner. This manual
explains how to assemble, install and operate the MovinCool CMW30 air
conditioning unit. Please read this operation manual thoroughly to familiarize
yourself with the features of the unit and to ensure years of reliable operation.
You may also find it useful to keep this operation manual on hand for reference.
Components and/or procedures are subject to change without prior notice.
Definition of Terms
WARNING: Describes precautions that should be observed in order
to prevent injury to the user during installation or unit operation.
CAUTION: Describes precautions that should be observed in order
to prevent damage to the unit or its components, which may occur
during installation or unit operation if sufficient care is not taken.
Note: Provides additional information that facilitates installation or unit operation.
GENERAL WARNINGS & CAUTIONS
1. All electrical work should only be performed by qualified electrical personnel.
Repair to electrical components by non-certified technicians may result in
personal injury and/or damage to the unit. All electrical components replaced
must be genuine MovinCool parts, purchased from an authorized reseller.
2. Installation should be conducted by qualified technician only. DENSO and
DENSO affiliate are not responsible for injuries and/or damages caused by
improper installation.
3. Disconnect power before any electrical installation. Beware that some residual
voltage may remain in the unit immediately after the power is disconnected.
4. The power supply for this unit should be a dedicated single outlet circuit with
UL recognized short-circuit and ground-fault protective breaker.
5. Do not place water or any other liquid on the unit. This can cause damage to
the unit and increase the risk of electrical shock.
6. Do not sit or stand on the unit.
7. Do not place hands or any object in the cool air outlet or exhaust duct.
Touching the fan, which is rotating at a high speed, is very hazardous.
8. Do not operate the unit without water connection or without supplied water.
9. Unit connects to water supply and water leakage may cause damage to the
equipment directly under the unit. Do not mount the unit over a sensitive
equipment or a field supplied secondary drain pan may be required under the
unit.

Mounting CMW30 to Roof Structure
ILL00256-00
Be sure to securely anchor the top ends of the suspension rods. Make sure all nuts
are tight. Be sure to follow all applicable codes.
The unit is usually mounted above the ceiling and must be securely mounted to
the roof structure. The ceiling support of the existing building may require
reinforcements.
WARNING: Make sure the supporting roof structure is capable of
supporting the weight of the unit, mounting hardware and the
accessories. Roof structure should be able to support four times of
total weight or more. Unit weight is 236 lb (107 kg).
The recommended clearance between ceiling grids and building structural
member is the unit height plus 3.0 inch (76 mm).
All mounting hardware except vibration isolators is field supplied.
Use the following hardware.

INSTALLATION (cont.)
Mounting CMW30 to Roof Structure (cont.)
Example of Mounting with Pallet
1. Install four (4) suspension rods by suspending them from suitable building
structure members. Locate the rods so that they will align with four mounting
holes that are part of the unit base. Make sure to securely anchor the top ends
of the suspension rods and tighten all nuts.
2. Insert four (4) nuts (top) to the suspension rods before mounting the unit (12.0
inch minimum height from the bottom end of the suspension rods).

INSTALLATION (cont.)
Water Pipe Connection
WARNING: Before wiring the unit, connect the water line to the unit.
To avoid electrical shock, make sure that there is no water splashed
onto the electrical box.
CMW30 unit is equipped with two female 3/4 inch NPT (National Pipe Thread)
connectors for water connections. Two water pipes with 3/4 inch NPT Male
connectors and proper insulators are required for field installation.
Connecting Water Pipes
1. Remove the caps from the NPT connectors on the rear side of the unit.
Note: Small residues of water may drip from the NPT connectors when the caps
are first removed.
2. Apply teflon tape to the NPT male connectors.
3. Connect the threaded water pipes or pipes with the NPT male connectors to
the NPT female connectors on the unit. Hold the wrench A tightly so that the
pipe on the unit is not deformed, then tighten the connector with the wrench B.
CAUTION: Use proper size wrenches.

4. Make sure the water inlet and outlet of the unit and water source are
connected, and there is no water leakage.
CAUTION: Supply water pressure limitation is maximum 150 psi
(1,034 kPa). Do not use the unit with water which contains a high
corrosive factor.
5. Attach the insulators to the water pipes and connectors to prevent
condensation.
ILL00333-00
CAUTION: If the insulators are not attached properly, condensation
may occur.
Note:
1. Service shut-off valves and drain plugs are recommended to be installed at the
water supply and return lines for routine field service or emergency service.
The drain plugs are used to drain the remaining water in the system. The shutoff valves and drain plugs should have a minimum pressure rating of 150 psi
(1,034 kPa). The drain plugs should be connected between the shut-off valves
and the unit.
2. When supply water quality is poor, filters that can be easily serviced should be
placed in the water supply line.

INSTALLATION (cont.)
Drain Hose Connection
The CMW30 is equipped with an
internal condensation removal pump
with maximum head lift of 4 feet (1.2 m).
1. Use the provided 1/2 inch (13 mm)
male connection on the unit for the
evaporator coil condensate drain.
The drain line must be located so it
will not be exposed to freezing
temperatures. The drain should be
the full size of the drain connection.
(Connect the drain hose to the
condensation drain or the janitor closet.)
2. PVC tubing (1/2 inch (13 mm) for ID, 5/8 inch (16 mm) for OD) is required for
the drain. Insulate the drain hose. Condensation may occur during humid
conditions.
Note: PVC tubing and insulation material are field supplied.

1. Plug in the 1/2 inch (13
mm) drain hose with the
supplied clip into the drain
pipe. Make sure the hose
is all the way in and flush
with the grommet.
2. Position the clip to the top
of the drain pipe near the
unit as shown.
STOPPER
3. Pull out the stopper and
secure hose. Make sure
there are no kinks or bends.
When using the gravity
drain, make sure the hose
is connected as a decline.
ILL00265-00
Note: Do not use more than 4 feet (1.2 m) of drain hose vertically. This is maximum
lift of the condensation pump.
3. To insure proper drainage, locate the drain hose to the highest vertical position,
no more than 4 feet (1.2 m) high, and run the hose to the drain on a downward
slope at a minimum rate of 1/4 inch (6 mm) per foot.

4. Check the following items.
• No kinks or bends on the drain hose
• No trap in the drain hose
• The end of the drain hose should be higher than the water level at the drain
• No dripping from the drain hose at the clamping area
• When uninstalling the unit, empty the drain pan by draining out the water
through the condensate pan drain pipe.

For the gravitational drain, power connection to the internal condensation removal
pump must be disconnected. Follow the procedures shown below.
CAUTION: The condensate water will drain out from the drain pipe
of the condensate pan if the internal condensation removal pump
connector is not disconnected.
1. Disconnect power.
2. Remove five (5) screws from the top
