Capacities rated using R404A with 10°F (5.6°C) TD & 100°F (38°C) liquid temperature.
Capacities at other TD within a range of 8 to 15 °F (4.4 to 8.3°C) are directly proportional to TD, or use formula:
Capacity = Rated capacity ÷ 5.6 x TD.
For capacities at TD outside of range 8 to 15 °F (4.4 to 8.3°C), or liquid temperature lower than 75°F (24°), consult factory .

INSTALLATION INSTRUCTIONS
INSTALLATION
The installation and start-up of Unit Coolers should only
be performed by qualified refrigeration mechanics.
This equipment should be installed in accordance with all
applicable codes, ordinances and local by-laws.
INSPECTION
Inspect all equipment before unpacking for visible signs of
damage or loss. Check shipping list against material
received to ensure shipment is complete.
IMPORTANT: Remember, you, the consignee, must make
any claim necessary against the transportation company .
Shipping damage or missing parts, when discovered at
the outset, will prevent later unnecessary and costly
delays.
If damage or loss during transport is evident, make
claim to carrier, as this will be their responsibility,
not the manufacturer’s.
Should carton be damaged, but damage to equipment is
not obvious, a claim should be filed for “concealed
damage” with the carrier.
IMPORTANT: The electrical characteristics of the unit
should be checked at this time to make sure they
correspond to those ordered and to electrical power
available at the job site.
Save all shipping papers, tags and instruction sheets for
reference by installer and owner .
APPLICATION
MP unit coolers are designed for walk-in cooler , walk-in
refrigerated warehouse and food processing plant applications used with refrigerant R22 or R404A. For room
temperatures above 35°F (2°C) AND evaporating temperatures above 26°F (-3°C), positive defrosting means (with
electric or hot gas) may not be required, otherwise,
electric defrost or hot gas defrost models should be used.
Electric defrost models come with defrost termination and
fan delay as standard to control the defrost cycle termination and fan delay , while defrost initiation means (e.g.
defrost timer) is not included.
For other types of refrigerant, contact factory .
The coil must not be exposed to any abnormal
atmospheric or acidic environments. This may result in
corrosion to the cabinet and possible coil failure (leaks).
(Consult manufacturer for optional baked on phenolic
protective coatings).
LOCATION
The unit location in the room should be selected to ensure
uniform air distribution throughout the entire space to be
refrigerated. Be sure that the product does not obstruct
the free circulation of air. Allow a minimum of 24” clearance at each end. Do not locate evaporators over doors.
Consideration should be given to the coil location in order
to minimize the piping run length to the
condensing unit and floor drain.
EXPANSION VALVE (TXV) SELECTION
All units require the use of an externally equalized
expansion valve. (A 1/4” (6 mm) O.D. equalizer line has
been provided on the coil) TX valves should not be
selected strictly by their nominal ton rating. (This rating
is based at a specific pressure differential and entering
liquid temperature). Since applications will differ it is
suggested the following selection procedure be followed.
1.Determine actual unit cooler capacity .
The nominal rating is based at 10
(Entering Air T emp. minus Evap. T emp.), R404A
refrigerant. For R22, use the rated capacity x 0.95.
For medium temperature R134a, use the rated
capacity x 0.90. Note that a higher / lower operating
T.D.will increase / decrease this capacity rating by
their direct ratio within a range of 8 to 12°F (4.4 to
6.7°C) T .D.
2.Determine the pressure drop across the valve by
subtracting the evaporating pressure and distributor
pressure drop from the high side liquid pressure.
The distributor pressure drop is typically in the range
of 20 to 35 psig (1.4 to 2.4 bar) depending on the type
of refrigerant and operating conditions.
3.Estimate entering liquid temperature. T emperatures
lower than 100°F (38 °C) increase valve capacity
ratings. Refer to valve manufacturer’s specs for
details.
4.Select valve from the valve manufacturer selection
charts or software for the appropriate refrigerant,
evaporating tempand pressure drop.
For best performance, the outlet of the expansion valve
should be installed directly to the distributor body . If this
is not possible, a straight tube up to 12 inches may be
used for the connection.
Locate the expansion valve bulb on a horizontal length
of suction line preferably 3 to 6 inches from the suction
header. Locate the bulb at 4 or 8 clock position and
insulate with a waterproof type of insulation. Clamp the
bulb to ensure 100% contact of the bulb with the
suction line.
For hot gas defrost models, ensure appropriate nozzle
has been installed in the distributor before installing
valve. After following the manufacturer’s installation
instructions and after the room has reached the desired
temperature the valve superheat should be checked.
This will confirm that the evaporator is operating
properly and performing to maximum efficiency . The
superheat should be around 60 to 80% of T .D. T oo high
or low a super heat will result in unsatisfactory system
performance and possible compressor problems.

INSTALLATION INSTRUCTIONS
NOZZLE INSTALLATION
All air defrost and electric defrost models use venturi
distributors and no nozzles required. For hot gas defrost
models, a nozzle has been pre-selected and factory
installed for common applications (Medium temp. R404A,
R22, 8 to 12°F (4.4 to 6.7°C) T.D.; low temp. R404A, 8 to
12°F (4 .4 to 6.7°C) T.D.). For other applications, refer to
the nozzle manufacturer for selection method. When
replacing a nozzle, the nozzle retainer clip (in distributor)
must be removed before inserting nozzle. Re-install clip
ensuring nozzle is properly in place. A small nozzle can
be drilled larger using the drill size listed in table on page
25. Ensure the hole must be accurately centered and
smooth. A lathe is preferred for the drilling.
MOUNTING
Refer to dimensional drawing for recommended mounting
arrangements. Ensure adequate clearance is provided
behind the coil as well as each end. The evaporators may
be mounted flush with ceiling with bolts, or hanging down
with rod hangers. When using rod hangers, allow adequate space between the top of the unit and the ceiling
for cleaning to comply with NSF Standard 7.
Ensure that the ceiling is level since the drain pan
has been sloped for drainage during the defrost
cycle.
DRAIN LINE
The drain line should be run from the drain connection,
sloping at least 1” (25 mm) per foot and should have the
size at least as large as the drain connection. A trap in a
warm area outside the room must be provided to allow
proper draining through the tubing. Connection should be
made to proper drainage facilities that comply with local
regulations.
T o prevent freeze-up when the temperature of the
refrigerated space is 35oF (2 °C) or lower , the drain line
should be heated along its run inside the cold room. The
heated drain line should be insulated. It is recommended
that the heater be energized at all times. A heat input of
20 watts per foot in a 28°F (-2°C) room and 30 watts per
foot for -20°F (-29°C) rooms, is satisfactory. Drain line
heaters are not required for constant room temperature
above 35°F (2°C).
Always trap evaporator drain line individually to prevent
vapor migration.
Ensure that the drain line has sufficient slope for
proper drainage (prevention of ice build up/blockage
in pan).
PIPING
Refrigeration grade piping must be used for all field
refrigeration piping. Refrigerant line sizes are important
and may not be the same size as the coil connections.
Consult ASHRAE handbook or other similar reference
book for proper line sizing.
Refrigerant piping and control system should be designed
to prevent possible liquid slugging (from oil or refrigerant)
of the compressors on start-up after the defrost cycle.
Also, it should prevent oil logging and minimize refrigerant
pressure drop.
For hot gas models, see pages 29 to 30 for
recommended piping.

INSTALLATION INSTRUCTIONS
WIRING
Wire system in accordance with governing standards and
local codes. See data and wiring diagrams on pages 4 to
21 for typical wiring arrangement. Electrical wiring is to be
sized in accordance with minimum circuit ampacity rating
(MCA). Size fuses used must not exceed the Maximum
Fuse Size ratings.
For ease of identifying the proper wiring terminal, unit
wiring is color coded and terminal block connections are
identified.
When fan delay thermostats (combination fan delay and
defrost termination) are installed, on start-up, the fans do
not operate until the coil temperature is reduced to
approximately 25oF (-4°C). It is normal for the fans to
cycle a few times until the room temperature is brought
down. At higher evaporating temperatures this control may
not close and therefore should either be by-passed
temporarily or replaced with an adjustable type. (set for a
higher temperature cut-in point).
MAINTENANCE
The unit should be periodically inspected for any dirt or ice
build-up on the fin surface and cleaned if necessary with a
soft whisk or brush. Also ensure coils inner (and outer)
drain pans do not have any ice build-up from improper
defrost operation. When replacing heater elements first
remove heater retainer brackets and heater clips.
SYSTEM CHECK
Before Start-Up:
1.All wiring should be in accordance with local codes.
2.Refrigerant lines should be properly sized.
3. All systems preferably include a liqud line solenoid
valve at immediately up stream of the expansion
valve.
4.Thorough evacuation and dehydration has been
performed.
5.The suction, discharge, and receiver service valves
must be open.
6.The system preferably include a liquid line filter drier
moisture indicator and suction filter.
7.Pour enough water into the drain pan to allow a
good check on drainage and seal the trap.
After Start-Up:
1. Check the oil level to be sure the oil charge is
correct.
2. On initial start up the fans do not start until coil
temperature is pulled down to approximately 25°F
(-4 °C) on the coil. Also, it is normal for the fan to
cycle a few times until the room temperature is
pulled down.
3. If necessary , temporarily by-pass fan delay control
(to run fans until room temp is lowered).
4. Be sure that the expansion valve is properly set to
provide the correct amount of superheat.
5. After the box temperature is close to reaching the
desired temperature, the evaporator superheat must
be checked and adjustment made if necessary.
In general, evaporators running with a TD of 10°F
(5.6 °C) should have a superheat reading of 6° to 8°F
(3.3°C to 4.4 °C). For evaporators with another T .D.,
thegeneral rule is that the superheat should be around
60 to 80% of T.D.
6. Heavy moisture loads are usually encountered
when starting the system for the first time. This may
cause a rapid build-up of frost on the unit cooler.
During the initial pull down, we suggest that the frost
build-up be watched and defrosted manually as required.
7. Observe that the system goes through at least one
complete DEFROST CYCLE.
