5. INSTALLATION
LOCATION 5.1
Select a site for the unit which is level, provides clearance for air circulation, and is
convenient for plumbing and electrical connections. It is recommended the unit be mounted
at the same elevation as the chamber; do not exceed a difference in elevation of greater
than 25 feet.
Ventilation requirements, the unit circulates air for cooling of the refrigeration unit. Air is
drawn in from one end of the unit and exhausts air from the other end. The unit should have
two feet of clear space on each end for air circulation, plus sufficient volume of air to
dissipate the heat generated.
Preferably the unit should be located close to the chamber. The unit is quiet, clean, and
suitable for an indoor location.
If the unit is to be mounted outside, it should be protected from the environment, particularly
rain, heat and direct sun. While the unit is constructed of stainless steel, exposure to the
elements will accelerate the aging process. Exposure to heat will decrease the efficiency of
the cooling system. Outdoor locations generally require longer plumbing runs, which also will
decrease the efficiency of the unit.
ELECTRICAL 5.2
The unit must be connected via a quick disconnect box, with 15 amp fuses. Power
requirements are 220 VAC, 50/60 Hz single phase. Voltage limits are 187 to 250 VAC; this
allows the unit to operate on either a 220 or 208 VAC configuration. When operating at 208
VAC or 50 Hz expect a 10% lower capacity.
Supply and return connections are routed to the chamber connections for the inside-
conditioning unit. Supply and return connections are 1/2" NPT (female); tubing runs should
be 3/4" tube. All tubing runs should be insulated with a closed cell pipe insulation material,
with a wall thickness of 3/4". Pressure rating of the tubing runs OUTSIDE OF THE
CHAMBER should be 50 PSI or greater, with a minimum temperature rating of 0 to 125
o
F.
Amron's recommendation is 3/4" soft copper tubing, for runs of up 50 ft. (25 ft. supply and 25
ft. return). For longer runs increase the tubing size to 1".
Connect the supply and return lines to the chamber inside conditioning unit connections on
the outside of the chamber. It does not matter which line is connected to which inside
condition unit connection.
Fill the unit with fluid, use 50% ethylene or propylene glycol and 50% water; fill to middle of
fluid sight glass. Turn unit on, check for leaks, and replenish fluid level when the system has
filled the tubing runs and the inside-conditioning unit. NOTE: Do not operate the system
without fluid, as the circulating pump requires fluid for lubrication and cooling.
