Accessories
HEPA Filter Kit
Installation of the HEPA kit (accessory sold separately)
Please follow the instructions for installing the HEPA accessory kit below:
1. Working from the front of the CTW-18 remove the front lower metal panel by removing the set screws. This will
allow access to the 2 screws to remove the evaporator panel.
2. Remove the 2 screws at bottom of panel that attaches the evaporator panel to the unit. Once the screws are removed,
the panel will drop down. This will release the evaporator panel.
3. Unbox both the HEPA accessory frame kit and
HEPA filter. These will be separately boxed.
Remove plastic bag covering the HEPA filter and
place HEPA filter inside the HEPA accessory kit
frame. Rubber bead of HEPA filter should be
facing out so it can be placed against the
evaporator of the unit which will make the air
tight seal.
4. Once the HEPA filter is placed inside the
frame kit it can now be attached to the unit. To
attach the HEPA accessory kit, align the 2 tabs on
the top of the kit with the 2 slots on the unit.
Push the kit as far up as possible and secure by
attaching the 2 screws at the bottom of the kit to
the unit. Tighten screws.
5. The HEPA accessory kit includes a stage 1
prefilter. The prefilter keeps large particulate
off of the HEPA filter and should be cleaned monthly. Keeping the prefilter clean will allow the unit to operate properly
and the HEPA filter to perform at peak efficiency. Clean the prefilter by sliding the filter out of the frame and hand
washing in water with a mild detergent or by using a vacuum cleaner. Allow prefilter to dry completely before replacing.
Recommended HEPA filter replacement cycle:
Change and replace HEPA filter every 6-12 months as needed.
*Neglect to change the HEPA filter per recommendations can result in substandard filtration performance and potential
damage to the CTW-18 portable water-cooled unit.
*Replacement OEM filters can only be purchased through ClimaTemp Portables or its Authorized Distributors. For
more information go to www.Clima-Temp.com

Operation
●Inspection before use
Check whether the cooling water is connected;
Check whether the power supply meets the requirements of the machine.
●Power switch
When the power is turned on, the power switch
indicator is on. Press the power switch button to turn
the machine on and off.
●Air volume selection
Press the air volume selection button to select the Hi
and Low air volume, the air volume indicator will
display the Hi and Low air volume setting.
●Temperature setting
Press the temperature setting button, the LED display
screen switches to the temperature setting mode, and
the temperature indicator flashes. Press the up and
down buttons to set your desired ambient temperature,
that is, operate in the ambient setting temperature
mode. The ambient temperature can be set between
64°F~95°F. Three seconds after the operation is
completed, the LED display screen automatically
reverts to the temperature display mode, and the
current ambient temperature is displayed as default.
When the ambient temperature is 1 °F. higher than the
set temperature, the compressor works and the air
outlet outputs cold air; When the ambient temperature
is 1 F lower than the set temperature, the compressor
disengages and the air outlet supplies ambient air.
●Timing setting
Press the timing setting button, the timing indicator will be on, the temperature indicator will be off, and the LED
display screen will display the timing shutdown time (12 hours). Press the up and down adjustment buttons to
select the shutdown time (1-12 hours) cyclically. After 3 seconds of operation, the LED display screen will resume
displaying the ambient temperature, and the temperature indicator will be on.
●“FL” Alarm indicator
If the condensate pump malfunctions and fills with water, the alarm indicator lights up in conjunction with an audible
alarm. The unit will shut down while the code is active. The LED display screen displays the corresponding fault
code “FL”. Servicing or troubleshooting of the pump may be necessary.

Maintenance and Inspection
Be careful
● Please clean the filter screen regularly. If there is dust and dirt on the filter screen, it will affect the air inlet
volume of the machine and may malfunction or cause machine failure,
● When cleaning the machine surface, do not use thinner, volatile oil and other chemicals, otherwise the
appearance quality of the machine will be affected,
● Be sure to cut off the power supply during maintenance and inspection.
●Winterization: Before keeping and storing the machine in winter (room temperature ≤ 0 ℃), be sure to drain
the cooling water in the heat ex-changer to prevent the heat ex-changer from freezing and cracking, which will
damage the unit.
Clean the filter screen.
(a) Take out the filter screen from the right side of the
air inlet grill;
(b) Use a vacuum cleaner to remove the dust on the
filter screen, and then use clean water to clean the
filter screen. After it is completely dried, it can be
restored.
Water Hose Kit storage box drainage.
Before keeping and storing the machine, please drain
the accumulated water in the hose kit storage box.
(a) Open the drain valve knob at the bottom of the rear
side of the machine clockwise to drain water;
(b) After the accumulated water is drained, the handle
of the drain valve can be closed counterclockwise;
(c) The handle of the drain valve is closed at the
horizontal position.
Heat exchanger drainage.
For winterization and before storing the machine in
winter (room temperature ≤ 0 ℃/32° F), please drain
the cooling water in the heat exchanger.
(a) Put the drain plug of the bottom heat exchanger at
the rear side of the machine into the hexagon groove
of the plug with an S5 Allen wrench and unscrew the
plug counterclockwise to drain;
(b) After the cooling water is drained, use the (S5)
Allen wrench to tighten the screw plug by turning it
clockwise.

Off Season Preventative Maintenance
To prolong the life of the CTW-18 it is necessary to follow regular seasonal maintenance as specified below:
WINTERIZATION - OFF SEASON STORAGE
For winterization and before storing the machine in winter (room temperature ≤ 0
℃
/32° F) it is recommended to
thoroughly clean and remove all water from the major components of the unit. Water should be removed from the
Heat Exchanger/Condenser Coil, Water Lines and Condensate Pump. Removing all water will avoid freezing
water from damaging the unit.
DRAINING THE HEAT EXCHNGER/CONDENSER COIL AND INTERIOR WATER LINES
For easy draining of the Heat Exchanger/Condenser Coil, the CTW-18 is equipped with a Heat Exchanger Drain
Valve. To drain the Heat Exchanger/Condenser Coil, access the drain plug groove which is located at the lower rear of
the unit. It is labeled Heat Exchanger Drain Valve. Place a Hexagon Allen wrench (S5) into the heat exchanger drain
valve groove and turn clockwise to drain the water. Water will exit the unit below the drain plug valve. See page 16 for
more instructions for Heat exchanger drainage. Place water collection tray underneath unit to collect any water exiting
the unit.
DRAINING THE QUICK CONNECT HOSE KIT
To drain the CTW-18 hose kit, disconnect all hoses from unit, connect lanyard fitting which is attached to the hose kit
ends, and allow the hoses to gravity drain.
REMOVING WATER FROM THE CONDENSATE PUMP
Access the condensate pump by removing the lower front cover of the unit. Using a Shop-Vac or similar vacuum
device manually vacuum all water out of the condensate pump reservoir.
STORAGE
The CTW-18 is not approved for outdoor use. Please store unit indoors and protect from all-weather
conditions.
