(see chart below)
A level concrete foundation is recommended.
A concrete foundation needs to be 8 in. (200mm) wider and 8
in. (200mm) longer than the chiller cabinet.
Leveling feet (Fig. 1 & 2) are used for vibration
isolation and height adjustment.
Rooftop curbing to be installed per your local building code
specifications.

1.6 Crane Transport:
If a crane will be used to transport the chiller, please note the following:
Lift the chiller only from its base. Insert two steel rods through the holes in the base. Rods
must be specifically designed for this purpose, and able to support the weight of the unit (see
chart).
Secure the rods with locking pins to prevent shifting. Use only lifting straps or rope for lifting
from the rod
The straps or ropes must be held in place with a frame to keep them from pressing into the
side walls, gutters, and condenser body. (Refer to the following graphic).
Metal rope or chains, must not be used!

2. Piping and Installation
2.1 Piping Materials Allowed
Use only the following materials for the pipes:
1. Copper is recommended
2. Stainless steel
3. PE or PVC – ensure that the appropriate steps are taken to protect the pipe along its length.
 Never use galvanized piping!

For distances exceeding 328 ft. (100M) of straight pipe one way, e-mail the actual pipe
length, the difference in height, and the required pipe elbows to
[e-mail].
Maximum allowed elbows in total piping run is ~ 20 pcs.
Long radius elbows must be used.

3.0 Technical Requirements
3.1 Glycol
The cBoxX chillers require a water/ glycol mixture of 35-37 percent glycol to water for regions
with ambient temperatures > -13F (-25C). Regions with colder temperatures require a low
ambient chiller model and higher glycol concentrations (up to 50%).
KKT recommends using Distilled, Demineralized or Reverse Osmosis water
Allowed Glycol: Ethylene
Prohibited :
Do not use automotive anti-freeze, or mixture containing >50% concentration of glycol.
DO not mix different brands or types of glycol without approval from the factory.
Tap water should not be used.
Required Volume
Piping Calculations:
Pipe size: 2-1/2” = 2.43 Gal/Ft. (2,8 ltr/mtr)
Pipe size: 2“ = 1.74 Gal/Ft. (2,0 ltr/mtr)
Pipe size: 1-1/2” = 1.04 Gal/Ft. (1,2 ltr/mtr)
Volume needed for the chiller is 13 gal. (50 l).
Take into consideration the amount of required glycol within the Healthcare application itself.
3.2 Air Vents:
Please ensure that air vents are placed at the highest point of the water loop in supply and
return line.
Example of automatic air vent:
KKT#:654936
Description: Air vent - EA122A1002
Price: $30.00 USD +S&H

830.013.02.K_Installation Guidelines (USA ONLY!) - cBoxX (Version 1.3).docx

Air vents must be installed at the highest point in system piping where large air bubbles
might collect.
4.0 Wiring Requirements:
4.1 Power Supply:
Supply wiring must be sized according to local codes and the technical data provided in the
chiller manual.
Wiring must be routed through the cut-outs provided in the baseplate, and compressor
mount. To protect your wiring, all wires should pass through the rubber grommets.
4.2 Grounding:
Proper isolation of the wiring for the control and power circuits, and shielding of cables is
required.
A large contact area is necessary for low-impedance grounding of HF interference. As such,
the use of grounding straps instead of cables is advised.
Moreover, cable shields must be connected with purpose-made ground clips. The grounding
surface must be highly conductive bare metal. Remove any coats of varnish and paint.
The grounding wire must be sized in accordance with local regulations, and at minimum, the
same gauge wire as connected to the main power supply. The grounding must be an “isolated
ground” and must be connected to the ground terminal in the main electrical cabinet of the
chiller. The ground resistance must be less than 5 Ohms.
