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.

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

support@kkt-chillersusa.com.

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.
