H. MAXIMUM AIRFLOW SETTING, CFM
NOTE:
Water blow-off could occur in certain installation posi-
tions if the airflow setting exceeds the maximum values
listed.
IMPORTANT:
Do not unseal refrigerant tubing until ready to fit refriger-
ant lines.
There is only a holding charge of dry air in the indoor coil,
therefore no loss of operating refrigerant charge occurs when
the sealing plugs are removed.
NOTE:
TXV bulb MUST be protected (wrapped with wet rag) or
removed, while brazing the tubing. Overheating of the
sensing bulb will affect the functional characteristics and
performance of the comfort coil.
1. Remove both rubber plugs from the indoor coil.
2. Field supplied tubing should be cut square, round and free
of burrs at the connecting end. Clean the tubing to prevent
contaminants from entering the system.
3. Run the refrigerant tubing into the stub tube sockets of
the indoor unit coil.
PAINTED AREAS OF THE UNIT MUST BE SHIELDED
DURING BRAZING.
4. Flow a small amount of nitrogen through the tubing while
brazing.
5. Use good brazing technique to make leakproof joints.
6. Minimize the use of sharp 90 degree bends.
7. Insulate the suction line and its fittings.
8. Do NOT allow un-insulated lines to come into contact with
each other.
I. INSTALLING / BRAZING REFRIGERANT LINES
▲
CAUTION
!
Do NOT open refrigerant valve at the outdoor unit until the
refrigerant lines and coil have been brazed, evacuated, and
leak checked. This would cause contamination of the refriger-
ant or possible discharge of refrigerant to the atmosphere.
1. The following steps are to be considered when installing
the refrigerant lines:
a. Determine the most practical way to run the lines.
b. Consider types of bends to be made and space limita-
tions.
c. Route the tubing making all required bends and properly
secure the tubing before making final connections.
NOTE: Refrigerant lines must be isolated from the structure
and the holes must be sealed weather tight after installation.
NOTE:
The TXV setting on this unit may run high superheat
(15-25°F) by design when measured at the outdoor unit.
