Air Defrost for Applications 35 °F
(1.6 °C) (Electric and Hot Gas Defrost
Models are Optional)
Up to 30 Tons Nominal Capacity
• Large face area centrifugal fan
• New “bolt-on” coil for maximum capacity in a minimum
space.
• Electronically balanced high efficiency fans with forward
curved blades provide quiet operation.
• Heavy gauge galvanized steel cabinet.
• Self-aligning ball bearings and heavy channel stiffeners
eliminate vibration and ensure quiet operation.

* For Applications in room temperatures above 35 °F (1.6 °C) maximum face velocity should not exceed 500 FPM
(152m/min) and capacities corrected accordingly (see table 1 for correction factors).
** These ratings are based on moderate coil frosting. For heavy frosting use factor of 0.95.
(1) “T.D.” - Represents the difference between temperature
of air entering cooling coil and coil refrigerant temperature.
Ratings for units using electric defrost may be determined by
multiplying ratings in above table by 0.95

INSTALLATION INSTRUCTIONS
GENERAL
The Product cooler should be carefully inspected for
damage when received. Visible or concealed damage
should be reported immediately to the carrier and a
claim filed for damage.
Product coolers are constructed from heavy gauge
galvanized steel and are thoroughly inspected before
leaving the plant. Care should be taken during
installation to prevent damage to the units.
Care should be taken to ensure that sufficient access is
available for servicing of the unit. Space should be
available for lubrication, belt adjustment and coil removal.
Fans and fan shafts should be inspected before start-up.
Fans are inspected before leaving the pant; however,
rough handling may cause misalignement.
LOCATING AND INSTALLATION HINTS
IMPORTANT: Product Coolers PCC3770, PCC4170,
PCC5070 and PCC6470 MUST be platform or floor
mounted.
Product Coolers may be placed in any suitable manner
in the room. However, low temperature units should not
be located over entrance doors, because of the heavy
frosting that will occur on the coils.
All Product Coolers must be installed level to ensure
proper drainage of water from the pre-engineered drain
pan.
Drain lines for all Product Cooler Models should be
pitched 45° and should be as short as possible. To
prevent drain line freezing problems the following recommendations should be carried out:
(a) Use a drain line heater (supplied by others) with a
density of 20 watts per foot. Six to eight feet of cable
per foot of drain line is recommended.
(b) Drain line heater should make at least a full turn
round the outlet of the drain pan.
distributor on the evaporator coil is equipped with a side
port connection to facilitate a hot gas connection.
Distributor tubes are oversized for hot gas operation.
A liquid line solenoid valve (supplied by others) should be
used so that evaporator coil may be pumped out before
each defrost cycle.
The following defrost control (supplied by others) methods
may be used with Product Coolers.
(1) TIME INITIATED- TEMPERATURE TERMINATED
When using a time initiated - temperatureterminated
method of defrosting a Paragon Timer 8145-20 or equal is
recommended for this application. Timer is used in
conjuction with a defrost termination thermostat. For 3
phase applications, the timer must be used with a contactor. As well as the defrost termination thermostat, the
timer will also have a fail safe feature built into unit.
The drfrost termination thermostat should be set at
approx. 35 °F (1.6 °C) and should be adjustable.
Differential should be 5 °F (2.8 °C) or less. Bulb should be
attached to a tube of the evaporator. As a part of this
system, a fan delay thermostat should be used to provide
a delay period between the end of the defrost and the
start-up of the fan. The fan delay thermostat should be
adjustable and set at 10-25 °F (5.6-13.9 °C) (depending on
application) and bulb should be attached to evaporator
tube. When installing thermostats, care should be taken
to ensure that bulbs are not attached to evaporator heater
tubes.
(2) TIME CONTROLLED OPERATION
Defrosting may also be carried out by a time contolled
sequense. This system utilizes a timer and fan delay
thermostat. Timer should have an adjustable length of
defrost from 2-110 minutes and should be Paragon 804520 or equal. Fan delay thermostat should be as indicated
in (1) above.
(c) The heated drain line should be insulated.
(d) The drain line should be provided with a trap outside
the freezer room. Traps should be filled with water
before initial start-up.
DEFROSTING
Product Coolers are obtainable with electric or hot gas
defrost systems. On hot gas defrost units, the
Initially, 4-30 minute defrost per day are reccomended.
However, it is important that the coil be completely
cleared of defrost at the end of the cycle. Should coil not
be cleared of all frost at the end of 30 minutes, more
frequent defrost of shorter duration should be used.
WIRING
For suggested wiring of defrost heaters see Drg. No.
41594D furnished with Product Cooler.

INSTALLATION INSTRUCTIONS
03/15/2007
ST ART - UP
(a) Before start-up equipment, the amperage of all electric
defrost heaters, including drain pan heaters, motor,
etc. should be checked to ensure satisfactory
operation.
(b) Leak test entire system and make sure all joints are
tight.
(c) Check fan and motor for correct rotation.
(d) Check alignment of fan and motor sheave and belt
tension. Belts should have approx. 1” deflection.
PERIODIC SERVICE AND MAINTENANCE
1. Check all moving parts every six months for wear .
2. Check bearing collar set screws for tightness every six
months.
3. Fan bearings are pre-lubricated and do not require
lubrication at time of installation. Extended lube lines
SERVICE LOG
will have grease fittings located on unit panel.
Specific greasing instructions should be carried out in
accordance with tags and l;abels attached to unit.
Careshould be taken not to over lubricate. Grease
should be applied when unit is running, adding slowly
until there is a slight bleeding of the grease at the
seals.
For continuous operation in clean areas, in an
operating temperature range from -40 °F (-4 °C) to
140 °F (60 °C), normal lubrication interval is six
months.
ARMV AC 781, available from both Standard Oil Company and Imperial Oil Company is the recommended
lubricant for all product cooler shaft bearings.
REPLACEMENT P ARTS
When replacement parts are required on units
manufactured by KeepRite Refrigeration, furnish factory
with unit model number and serial number as shown on
serial plate on drive end blower section.
