5.6.1 Strainer Kit: MSF-NP63A and MSF-NP112A
When connecting a wall mount type indoor unit to the VRF system, make sure to attach the strainer kit to
the refrigerant piping close to the indoor unit . This prevents solid particles from entering into the electronic
expansion valve inside the unit.
NOTES:
1. Attach the strainer close to the indoor unit to facilitate replacement work.
2. When the strainer is attached to an inside wall or roof space, provide a service access door for
maintenance.
3. When on-site piping has a buried joint such as a pipe elbow socket, provide a service access door to
facilitate checking for connecting parts.
4. In order to prevent condensation, apply tape over the insulation material (accessory) and secure with
plastic bands.
5. Refer to the "Installation Manual for Strainer Kit" for more details.
