Product Horizontalizing; Anti-Vibration Device Installation; Standard Anti-Vibration - LG RCWFL Series Installation Manual

6-2. Product Horizontalizing

Make sure to secure the horizontality of the product when installing to secure the refrigerant level and reliability of
the stable Centrifugal Chiller while operating. (Maintain below 0.5mm for 1 m) Consider all front/back/left/right, length
direction and width direction when securing the horizontality.
** How to secure horizontality
1) Using a level
: Adjust horizontality by using Shell length direction or compressor Base for the length direction.
Secure horizontality by using the Centrifugal Chiller Base for width direction.
2) Using the difference of water levels(use transparent vinyl hose)
: Secure horizontality in a way that water levels are in the same position after marking the same position from
the base on the tubes on each side of the length direction of the product and fixing the vinyl hose by using a
transparent vinyl hose. Secure horizontality for the width direction by same method.

6-3. Anti-vibration Device Installation

Install the anti-vibration pad or anti-vibration spring (option) at the base of the product to minimize noise and vibration
propagation through a structure of a building.
6-3-1. Standard anti-vibration (anti-vibration pad) and Anchor Bolt Work
1) Install basic anti-vibration devices following the Figure 9 anti-vibration pad and Set Anchor Bolt Work Order
shown below at the base of the product.
Contact LG Electronics if anchor applications other than Set Anchor Bolt are needed.
2) Option (anti-vibration spring)
Contact LG Electronics for the anti-vibration specification and installation method when installing the optional
anti-vibration spring.
!
CAUTION
Adjustment of the anti-vibration spring should be implemented after the pipes are filled with the refrigerant or
water.
