EXAMPLE
--Pulley dimensions 2.9 to 3.9 (full close to full open)
--3.9 -- 2.9 = 1
--1 divided by 5 (turns from full close to full open)
--0.2 change in pulley diameter per turn open
--2.9 + 0.2 = 3.1--in pulley diameter when pulley closed
one turn from full open

UNIT OPERATION AND SAFETY HAZARD
Failure to follow this warning could cause personal
injury, death and/or equipment damage.
This system uses Puron
R
refrigerant which has
higher pressures than R--22 and other refrigerants. No
other refrigerant can be used in this system. Gauge
set, hoses, and recovery system must be designed to
handle Puron refrigerant. If unsure about equipment,
consult the equipment manufacturer.

WARNING
FIRE, EXPLOSION HAZARD
Failure to follow this warning could result in death,
serious personal injury and/or property damage.
Never use non--certified refrigerants in this product.
Non--certified refrigerants could contain contaminates
that could lead to unsafe operating conditions. Use
ONLY refrigerants that conform to AHRI Standard
700.

WARNING
Condenser Coils Size D08--D14
All 48TC units are available with Round Tube/Plate Fin
(RTPF) coil construction. 48TC units with size
designations D08, D12 and D14 are also available with
optional all--aluminum Novation coil construction. Check
position 11 on the unit’s infomative data plate for coil
construction code, then refer to Model Nomenclature on
page 5 to confirm this unit’s coil construction type.
Novation (MCHX) Condenser Coil
The condenser coil uses new NOVATION
Heat
Exchanger Technology or Microchannel Heat Exchanger.
Coil (MCHX). This is an all--aluminum construction with
louvered fins over single--depth crosstubes. The crosstubes
have multiple small passages (microchannels) through
which the refrigerant passes from header to header on
each end.
Tubes and fins are made of aluminum.
Connection tube joints are made of copper. The coil can
be one--row or two--row. Two--row coils are spaced apart
to assist in cleaning. See Fig. 14.
Routine Cleaning of NOVATION Condenser Coil
Surfaces
DO NOT clean the NOVATION condenser coil with
chemicals. ONLY water is approved as the cleaning
solution. Only clean potable water is authorized for
cleaning NOVATION condensers. Carefully remove any
foreign objects or debris attached to the coil face or
trapped within the mounting frame and brackets. Using a
high pressure water sprayer, purge any soap or industrial
cleaners from hose and/or dilution tank prior to wetting
the coil.
EXPLOSION HAZARD
Failure to follow this warning could
result in death, serious personal injury,
and/or property damage.
Never use air or gases containing
oxygen for leak testing or operating
refrigerant compressors. Pressurized
mixtures of air or gases containing
oxygen can lead to an explosion.
