1 Refrigerant HFC (R410A)
This air conditioner adopts the new refrigerant HFC (R410A) which
does not damage the ozone layer.
The working pressure of the new refrigerant R410A is 1.6 times higher than
conventional refrigerant (R22).
The refrigerating oil is also changed in accordance with change of refrigerant, so
be careful that water, dust, and existing refrigerant or refrigerating oil are not
entered in the refrigerant cycle of the air conditioner using the new refrigerant
during installation work or servicing time.
1. Required Tools
The service port diameter of packed valve of the outdoor unit in the air
conditioner using R410A is changed to prevent mixing of other refrigerant. To
reinforce the pressure-resisting strength, flare processing dimensions and
opposite side dimension of flare nut of the refrigerant piping are lengthened.
Tools exclusive for R410A (The following tools for R410A are required.)
Tools whose specifications are changed for R410A and their interchangeability

(Note 1)
When flaring is carried out for R410A using the conventional flare tools, adjustment of
projection margin is necessary. For this adjustment, a copper pipe gauge, etc. are necessary.
(Note 2)
Charging cylinder for R410A is being currently developed.

2. Refrigerant charge
Up to 20m piape length, no need to add refrigerant.
Exceed 20m, add the specified amount of the refrigerant.
Refrigerant adding procedure
1) After vacuuming the pipe, charge the refrigerant with the valve close.
2) When the specified amount of the refrigerant cannot be charged, add the
remained refrigerant from charging port of the valve at gas side with cooling
operation.
Record the added amount of the refrigerant in the site.
(Note)
Charge the refrigerant as liquid state. Otherwise the component of the refrigerant varies and
the normal operation is disabled.
