INSTALLATION
Location —
Do not store units in an area exposed to weath-
er because of sensitive control mechanisms and electronic
devices. Locate unit indoors. Model number structure is shown
in Fig. 3. See Fig. 4 and 5 for unit dimensional details.
When considering location, consult National Electrical
Code (NEC) and local code requirements. Allow sufficient
space for wiring, piping, and service. Install unit in an area
where it will not be exposed to ambient temperatures below
50 F (10 C).
Allow 36 in. (914 mm) in front of the unit for control box
access door. Additional clearance may be required per local
codes. Prior to installation determine which direction compres-
sor will be removed, and leave 3 to 4 ft (914 to 1219 mm)
clearance for removal.
On all units leave 3 ft (0.9 m) of clearance behind the unit to
make water/brine connections to the evaporator, accessing the
TXV (thermostatic expansion valve), fluid thermistors, and
proof of flow switch.
On all units, leave 2 ft (610 mm) on one side for making re-
frigeration connections (30MPA) or fluid connections
(30MPW) to condenser. See Fig. 4 and 5.
The floor must be strong enough to support the unit operat-
ing weight (see Tables 1A and 1B and Fig. 4-6). If necessary,
add a supporting structure (steel beams or reinforced concrete
slabs) to the floor to transfer weight to nearest beams.
Additional weight of factory-installed sound enclosure option is
75 lb (34 kg).
WARNING
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and gog-
gles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from sys-
tem using both high-pressure and low pressure ports.
c. Traces of vapor should be displaced with nitrogen
and the work area should be well ventilated. Refrig-
erant in contact with an open flame produces toxic
gases.
d. Cut component connection tubing with tubing cutter
and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when nec-
essary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal
injury or death.
CAUTION
DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes
and regulations. DO NOT leave refrigerant system open to
air any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with
dry nitrogen to prevent oil contamination when timely
repairs cannot be completed. Failure to follow these proce-
dures may result in damage to equipment.
CAUTION
Be sure interconnecting piping and electrical conduits
are suspended freely, and are not in contact with any
adjacent walls. Be sure unit capillaries are not rubbing
against anything. Damage to unit or walls may result.
