CAUTION
Hansen Frost Master® defrost controls are only for
refrigeration systems. These instructions and related
safety precautions must be read completely and
understood before selecting, using, or servicing these
controls. Only knowledgeable, trained refrigeration
mechanics should install, operate, or service these
controls. Stated electrical and temperature ranges
should not be exceeded. Any wiring and application
diagrams provided are for illustration purposes only.
The system designer has the final responsibility as
to how these defrost controls are connected, set and
operated. The designer is also responsible for systems
and components being designed to prevent abnormal
pressures or velocity impact pressure surges. Where
critical temperatures or products are involved, back-
up temperature controls or alarms are required. See
also Safety Precautions in current List Price Bulletin
and Safety Precautions Sheet supplied with product.
Escaping refrigerant might cause personal injury,
particularly to the eyes and lungs.
SERVICE AND MAINTENANCE
These controllers require practically no service or
maintenance. The only field replaceable components
are the time clocks (24 hour clock, -A suffix, p/n
67-0007 or -B suffix, p/n 67-0029; or 7 day clock, -A
suffix, p/n 67-0009 or -B suffix, p/n 67-0030) for all
models and the terminate temperature sensor (p/n 67-
0052) for the Frost Master® Plus. To replace clock,
disconnect all power to control unit. Remove each
of three 5/32” socket cap screws located at corners
of clock. Carefully pry clock away with hand. Install
new clock by inserting its spade terminals into the
clamp connectors located on the controller. Replace
screws, restore power, and set time-of-day and defrost
start times.
WARRANTY
Hansen defrost controllers are guaranteed against
defective materials or workmanship for 90 days F.O.B.
our plant. No consequential damages or field labor
is included.
REMOTE INITIATE MODELS
Remote Initiate Models FM-01, FM-02 and FMP-01 are
supplied less any time clock and horizontal jumper
wire. The defrost begins when the initiate spade
terminals are momentarily closed. The next defrost
will occur as soon as the present defrost is completed
and the initiate terminals are opened and then re-
closed. This model is especially well suited for use
with plant computers, PLC’s, production equipment
control relays, push buttons, etc.
TYPICAL SPECIFICATIONS
“Defrost controls shall have the ability to pump down
evaporator, apply hot gas for frost removal, equalize
evaporator pressure, and delay fans. Furthermore,
they shall provide connections for optional initiate and
terminate defrost devices, be capable of staggering
defrosts so as not to allow too many evaporators or
evaporators in close proximity to one another from
going into defrost at the same time. They shall provide
a remote initiate device connection, or 24 hour or 7-day
scheduling time clock with battery back-up in case of
short term power failure as manufactured by Hansen
Technologies Corporation or approved equal.”
