About This Manual
Literature Change History
Use this manual for commercial blower
coil models BCHC and BCVC. This is the
first version of this manual. This manual
supercedes BCXB-SVX01B-EN, which
was for the previous models BCHB and
BCVB. It provides specific installation,
operation, and maintenance instructions
for "AO" and later design sequences.
Models BCHC/BCVC include the following
design changes that differ from the
BCHB/BCVB:
• standard and high-capacity hydronic
cooling & heating coils
• DX coils
• steam preheat coil
• stainless steel drain pan option
• bottom/top filter access box

equipment damage.
General
Information
Special Note on Refrigeration
Emissions
World environmental scientists have
concluded that ozone in our upper
atmosphere is being reduced due to the
release of CFC fully halogenated

prevent any refrigerant emissions while
installing, operating, or servicing
equipment. Always conserve
refrigerants for continued use and follow
all warnings and cautions in this manual.
