* When using R407C, the factor above is to be used when matching to condensing units with Dew Point ratings. This factor will ensure that proper
system balancing will occur to compensate for glide to t the application. If the system is sized correctly, one may expect a slight increase in system
capacity, along with slightly higher saturated suction temperatures.

INSTALLATION INSTRUCTIONS

60Hz

INSTALLATION

The installation and start-up of LV Evaporators should only be
performed by qualied 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 led 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.

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 unit does not draw air in, or

blow directly out, through an opened door and that the
product does not obstruct the free circulation of air. Allow a

minimum of 24” clearance at each end. LV Evaporators draw
air through the fans and discharge air through both coils.

Consideration should be given to the coil location in order
to minimize the piping run length to the condensing unit and
oor 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 specic
pressure differential and entering liquid
temperature). Since applications will differ it is suggested the
following selection procedure be followed.

1. Determine actual unit cooler BTUH or KW (thermal).
The nominal rating is based at 10 °F T.D. (5 .5°C)
(Room Temp. minus Evap. Temp.). Note that a higher /
lower operating T.D.will increase / decrease this capacity
rating by their direct ratio.

Save all shipping papers, tags and instruction sheets for
reference by installer and owner.

APPLICATION

LV Unit Coolers are designed for use with R22, R404A, R134a,
R407C or R507 refrigerants. At room temperatures above 34°F
(1.1 C) (and evaporating temps no lower than 24 °F (-4.4°C))
positive coil defrosting (Electric or Hot Gas) is not required. (The
air owing through the coil will accomplish the defrost). At room
temperatures of 34°F (1.1°C) and below, positive defrosting is
required (either Electric (ED) or Hot Gas (HE, RE, TE) in model
nomenclature). These models require the use of (1) Time Clock
or equivalent (to initiate and terminate the defrost cycle), and (2)
Defrost Termination Control (to prevent unnecessary prolonged
heating and steaming of the coil once all the ice and frost has
melted), (3) Hot Gas models also utilize a Fan/Heater drain pan
control.

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).

2. Determine the pressure drop across the valve by
subtracting the suction (evaporating) pressure from the
high side liquid pressure. Note: Also subtract the
distributor pressure loss (use approx. 25 psig (1.1 bar)
for R134a and 35 psig (2.4 bar) for R22, R404A, R507).

3. Estimate entering liquid temperature. Temperatures
lower than 100 °F (37.7 °C) increase valve capacity
ratings. Refer to valve manufacturer’s specs for details.

4. Select valve from the valve manufacturer selection charts
for the appropriate refrigerant, evaporating temp and
pressure drop.

5. After following the manufacturer’s installation instructions
and after the room has reached the desired temperature
the valve superheat should be checked. This will conrm
that the evaporator is operating properly and performing
to maximum efciency. The superheat should be around
5 (2.7°C) to 8 °F (4.4°C) for a 10 to 12 °F (5.5 to 6.6°C)
T.D. Too high or low a super heat will result in
unsatisfactory system performance and possible
compressor problems.

NOZZLE INSTALLATION

All LV Evaporators have nozzles installed at factory. For noz­zle selection refer to selection table. In case it is
required to install the nozzle at some point in the future, the
nozzle retainer clip (in distributor) must be removed before
inserting nozzle. Re-install clip ensuring nozzle is properly in
place.

INSTALLATION INSTRUCTIONS (cont’d)

60Hz

MOUNTING

Refer to dimensional drawing for recommended mounting ar­rangements. Formed mounting channels are provided for ush
mounting to the ceiling. Ensure adequate clearance (at least
24” (600 mm)) is provided at each end (to enable access to the
electrical and refrig. compartments).

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 1/4” (6 mm) per foot. A trap in a warm area outside the
room will allow proper draining through the tubing. Connection
should be made to proper drainage facilities that comply with
local regulations.
To prevent freeze-up when the temperature of the refrigerated
space is 35
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 (-2.2°C)
room, is satisfactory. Drain line heaters are not required for
constant room temperature above 35°F (1.6°C).

Ensure that the drain line has sufcient slope for proper
drainage (prevention of ice build up/blockage in pan).

o

F (1.7 °C) or lower, the drain line should be heated

PIPING

Refrigerant line sizes are important and may not be the same
size as the coil connections. Consult “Recommended refriger­ant line sizes” charts in any standard 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. On Hot Gas
Defrost Systems the suction accumulator should be at least 2.5
times the coils operating charge.

See Dimensional data for line locations. For Reverse Cycle
and Hot Gas models and 3-Pipe - see g. 2 & 3 respectively on
page 12 for typical unit piping. These models include a check
valve (unmounted) packaged along with the nozzle in the
refrig. connection compartment end panel.

WIRING

Wire system in accordance with governing standards and local
codes. See data and wiring diagrams on pages 6 to 10 for wir­ing arrangement. Electrical wiring is to be sized in accordance
with minimum circuit ampacity rating (MCA).

For ease of identifying the proper wiring terminal, unit wiring is
color coded and terminal block connections are identied.

SYSTEM CHECK

Before Start-Up:

1. All wiring should be in accordance with local codes.

2. Refrigerant lines should be properly sized.

3. Off cycle defrost and electric defrost systems preferably
must include a liqud line solenoid valve and suction
accumulator.

4. Thorough evacuation and, dehydration has been
performed.

5. The suction, discharge, and receiver service valves must
be open.

6. The system preferably must include a liquid line drier
moisture indicator and suction lter.

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 35 °F (1.7 °C) on the hot
gas coil. Also, it is normal for the fans to cycle a few times
until the room temperature is pulled down.

3. Fan/Heater control and defrost termination control is
factory installed for reverse cycle defrost operation. Refer
to Fig. 1 on page 12.

4. If coil is to be used for 3-pipe (bypass) Hot Gas Defrost,
Fan/Heater must be moved from suction line to hot gas
inlet line and the defrost termination control moved to the
suction line. Refer to Fig. 1 on page 12.

5. In general, evaporators running with a TD of 10 °F should
have a superheat reading of 5° to 8 °F (2.7 °C to 4.4 °C).
For evaporators with a higher TD, the superheat should be
8° to 12°F (4.4 °C to 6.6 °C).

6. Heavy moisture loads are usually encountered when
starting the system for the rst time. This will 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. This may be done by
rotating the inner dial on the timer until the pin in the outer
dial is directly opposite the timer pointer. (Paragon 8145-
20 Timer by others).

7. Observe that the system goes through at least one
complete DEFROST CYCLE.

MAINTENANCE

The unit should be periodically inspected for any dirt or
build-up on the n 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 rst remove heater retainer
brackets and heater clips.
