Locating and Mounting Evaporator Coil
General Guidelines:
Do not place the evaporator above or close to door openings. This will help
prevent potential icing problems.
Allow a minimum clearance equal to or greater than the coil height on all sides of
the coil for proper air flow and service access.
Use the evaporator coil for a template to locate and drill the mounting holes (1/2”
diameter).
Place a 1” and a 1-5/8” washer on each nylon bolt and insert through the drilled
mounting holes in the ceiling from the exterior of the walk-in ceiling panel.
NOTE: Nylon bolts are supplied to prevent thermal transfer between the exterior
of the walk-in and the interior of the walk-in. Do not use metal bolts.
Lift the evaporator coil until the nylon bolts extend through the mounting
brackets.
Install washers and secure with nuts. Tighten until the coil is firm against the
ceiling. The evaporator coil must be level.
Additional information is available in the installation manual supplied with the
evaporator.

Wiring
All electrical connections and routing must comply with local and national codes. Do not
modify the factory installed wiring without written factory approval. The field wiring must
enter through the knockouts provided. Refer to the nameplate on the condensing or
evaporator coil to determine the proper electrical power supply. Wire type should be of
copper conductor only and properly sized to handle the electrical load. The unit and coil
must be properly grounded. Condensing unit wiring diagrams are located inside this
installation manual and attached inside the electrical box cover. Evaporator coil wiring
diagrams are located inside this installation manual and inside the evaporator cov er .
NOTE: CAT-5 cables, which are included, need to be routed from the evaporators
to the network router for access to the internet. Please contact the end user for
proper connection point.

MISE EN GARDE
All wiring must comply with local and national codes. Wiring must be performed only
by a refrigeration technician or certified electrician. Failure to follow these guidelines
Tout le câblage doit être conforme aux codes locaux et nationaux. Le
câblage ne doit être effectué que par un technicien en réfrigération ou un
électricien agréé. Le non-respect de ces consignes peut entraîner des
blessures!

Vérifier toutes les connexions de câblage, y compris les bornes installées
en usine, avant de faire fonctionner l’appareil. Les connexions peuvent
devenir lâches pendant l’expédition et l’installation.
Piping
General Requirements:
All refrigeration piping and components are to be installed in accordance with applicable
local and national codes and in conformance with industry refrigeration guidelines to
ensure proper operation of the refrigeration system. Only refrigeration grade copper
tubing should be used. Long radius elbows should be used. Short radius elbows have
points of excessive stress concentration and are subject to breaking at these points, do
not use short radius elbows. Suction lines must be insulated with a minimum ¾” thick
insulation tubing to reduce heat pick-up.

Cleanliness:
Condensing units and evaporator coils are cleaned and dehydrated at the factory. The
condensing unit must remain closed and pressurized until the piping is complete and
final connections are r eady to be made.
The maximum air exposure for dehydrated condensing units is 15 minutes. Systems
exposed longer than 15 minutes must have the compressor oil and drier filter
replaced. Leaving a system exposed to the atmosphere for more than 15 minutes
L’exposition maximale à l’air des groupes compresseurs-condenseurs
déshydratés es t de 15 minutes. L’huile du compresseur et le filtre du
dessiccateur doivent être remplacés sur les systèmes qui ont été exposés à
l’air pendant plus de 15 minutes. L’exposition d’un système à l’atmosphère
pendant plus de 15 minutes peut avoir pour résultat une défaillance
prématurée du système.
Do not remove base mount valve covers until work is ready to be performed. Ensure
that all refrigeration tubing is clean and dry prior to installation. Use only tubing cutters
when trimming tubing to the proper length. Do not use saws to cut tubing.
The use of saws to cut tubing can contaminate the system with copper chips causing

resulting in premature c ompressor failure.
MISE EN GARDE
Brazing joints require a dry inert gas, typically nitrogen, be passed through the lines at a
low pressure to prevent scaling and oxidation. Use only silver solder brazing alloys.
Minimize the amount of flux to prevent internal contamination. Flux only the male
portion of the joint. Thoroughly clean fluxed joints after brazing.
Dry inert gas must be passed through the system while brazing to prevent scaling and
oxidation. Scaling and oxides can clog refrigeration components resulting in system
Le gaz sec inerte doit passer par le système pendant le brasage afin de
prévenir l’entartrage et l’oxydation. Le tartre et les oxydes peuvent
bloquer les éléments de réfrigération et causer une défaillance du système.
Pipe Supports:
All tubing should be supported in at least two locations (near the end of each tubing
run). Long runs will require additional support. As a guide, support 3/8” to 7/8” pipe
every five feet, 1-1/8” to 1-3/8” every seven feet, and 1-5/8” to 2-1/8” every ten feet. Do
not leave a corner unsupported when changing directions. Place supports within 2 feet
of each direction change. Piping that is attached to a vibrating object (such as a
compressor or compressor base) must be supported in a manner that will not restrict
the movement of the vibrating object. Rigid mounting will fatigue the tubing causing
refrigerant leaks.
Oil Traps:
To ensure proper oil return to the compressor, a P-type oil trap should be installed at
the base of each suction riser of four feet or more. The suction trap must be the same
size as the suction line. Additional traps are necessary for long vertical risers. Add a
trap for each length of pipe (approximately 20 feet) to insure proper oil return. Suction
lines must slope ¼” per 10 feet toward the compressor. Install a suction line trap at the
evaporator outlet if the suction line rises to a point higher than the connection on the
evaporator.
Failure to properly install oil traps can prevent sufficient oil return to the compressor
L’installation incorrecte des siphons d’huile peut empêcher un retour
d’huile suffisant au compresseur, entraînant une défaillance prématurée du
compresseur.

WARNING
AVERTISSEMENT
Pressure Regulating-Relief Valves:
Do not defeat, cap, add piping to the outlet of the valve, or, attempt to
change the relief setting.
Ne pas annuler, mettre un capuchon, ajouter de la tuyauterie à la prise de
la valve ou tenter de modifier le réglage de décharge.
Drain Lines:
Evaporator coil drain lines shoul d be pi tched a minimum of 1/2” per foot to allow proper
drainage and exit the wal k-in as quickly as possible. Insulate and seal the drain line
where it passes through the wall. Copper drain line is required. Freezer compartment
drain lines must have heat tape wrapped around the copper drain line and must have
¾” thick insulation tubing. Do not locate drain line P-traps within the freezer space. Do
not reduce the drain line size. Locate a drain line P-trap outside o f the cooler space.
Any outdoor P-traps exposed to low ambient temperatures should be wrapped with a
drain line heater (provide 20 watts of heat per foot of drain line at 0°F, 30 watts per foot
at -20°F. Freezer/cooler combo boxes can have one common drain line. However,
there must be a P-trap located between the freezer evaporator and the cooler
evaporator located inside the cooler compartment. The cooler compartment P-trap
should be located between the cooler evaporator and the external drain location.
