IMPORTANT

1. The use of this manual is specifically intended for a

qualified installation and service agency. All installation

and service of these kits must be performed by a qualified

installation and service agency.

2. These instructions must also be used in conjunction with

the Installation and Service (I&S) Manual originally

shipped with the appliance being converted, in addition to

any other accompanying component supplier literature.

VIBRATION ISOLATION HANGER KIT

Model Application

All mechanical equipment with moving parts has the potential

to generate sound and vibration. Many factors can affect the

level of vibration transmitted to the supporting structure

including the installation method, design, and construction of

the supporting structure, and the design of the unit itself.

Modine offers vibration isolation kits for Models PTC (55-260),

HD/HDB & HDS/HDC, that when used in combination with

these instructions, can reduce unit vibration transmitted to the

structure to a negligible amount. The items and quantity

required for installation are as follows:

To ensure that the maximum vibration isolation is achieved,

follow these instructions in detail. For complete installation

instructions, please refer to the latest revision of I&S Manuals.

Assembly/Installation

The recommended procedure for assembly and installation is

described as follows (for each step, refer to Figure 1.1):

1. Install the 3/8" threaded rod to the supporting structure in

accordance with I&S Manual that shipped with the model

being installed. Space the rods according to the hole

locations on the unit. To increase the effectiveness of the

isolation, ensure that the threaded rods are vertical.

Creating a template of the rail spacing may be useful in

transferring the distances.

2. Place a nut approximately 3/4" from the end of the

hanging rod. Below this nut, install a washer and the

vibration isolation hanger. The hanger should be in a

vertical orientation with the neoprene isolator at the

bottom. Secure the hanger with a washer and nut. The

nuts above and below the vibration isolation hanger

should be tightened to prevent the nuts from loosening.

3. Once the vibration isolation hanger has been adequately

attached to the threaded rod, guide a section of threaded

rod that will eventually be secured to the unit, through the

bottom of the hanger so that it protrudes above the top of

the neoprene isolator. Place the 1.5” fender washer that

was included with the kit, followed by two nuts on the

threaded rod and tighten the two nuts against each other

to prevent the nuts from loosening.

4. At the end of the threaded rod, place one nut

approximately 1-1/2" from the bottom end of the rod.

Before suspending the unit, repeat steps 1-4 for the

remaining suspension rod/vibration hangers.

5. Once the threaded rod/vibration hangers installation steps

1-4 are complete, suspend the unit by placing a washer

on the end of the threaded rod, followed by the unit

through the appropriate hole in the mounting bracket,

followed by a washer, and two nuts. Repeat for the other

suspension points. Ensure that the unit is level as

outlined in the unit I&S Manual and tighten the nuts

closest to the bracket on the bottom. This will secure the

unit against the previously installed nut from step 4.

Tighten the 2

nut under the bracket so the double nut

arrangement will keep the nuts from loosening.

6. Verify the unit is level, then continue with the installation

instructions in the I&S Manual that shipped with the unit.
