2. Feature

New valve cover design

Less screws to open valve cover

Easy to vacuum

Appearance

Installation

Compared with the current 1:3 valve cover , we design the new valve cover , which is more slim in the appearance;

In the installation course , installer need to take down the valve cover , then to do wiring and piping , next is the

comparison in taking down the valve cover;

General stop valve vacuum every indoor unit from one valve only , save time. ( for 1:4 outdoor unit)

Current R410a 1:3

Cover length

72.5mm

New R32 1:3

Cover length

Easy to carry

Easy start up & maintenance

Left & right two handles are easy for two people carry the units;

* “88” screen show compressor frequency or failure code,

* On site testing software check all running data ;

This two tools make easy start up & maintenance ;

Cooling only /heating only

Central control/BMS control

Solution Supplier

Cooling only /heating only function for special requirement;

Central control / BMS control function meet the various needs for designer;

Note: BMS control is the function in the future
