THERMO-CYCLER® GTC-400/GTC-480/GTC-480M
Installation Instructions Summary
A) Carefully unload and inspect the unit for any damage which may have occurred in transit and file any necessary claims within prescribed time. A complete Thermo-Cycler will consist of one (1) base fan section with one (1) top discharge section bolted to the base for shipping, and one (1) center heat exchanger section shipped on two separate pallets. Any additional accessories ordered will be shipped separately.
B) Carefully remove packaging materials, unbolt and remove sections from the shipping pallets. Keys to open the unit enclosures will
be attached to the center and base sections. Locate the small parts bag (shipped in the burner enclosure cabinet) which contains the
nuts, bolts, time clock control pins, control panel keys, and pipe fittings. Put the bag in a secure location for later use.
C) Locate the unit on a smooth, level, surface which is structurally capable of supporting the Thermo-Cycler unit. For proper system
performance and operation, unit should be located in accordance with the Thermo-Cycler Representative or Dealer's instructions.
Maintain clearance to combustible materials in accordance with applicable codes and regulations. For additional information, please
refer to the Thermo-Cycler Installation, Operation, and Maintenance Manual which is located in the control cabinet of the base fan
section.
D) Set the base fan section with the access door facing an area that will allow adequate access and space for service and
maintenance.
E) Carefully lift the center heat exchanger section using the lifting hook provided on the top of the heat exchanger. Make sure that the
burner cover is located on the same side above the base section control panel and access door. Using a drift pin or other suitable tool
for hole alignment, lower the heat exchanger on to the base section, insert bolts and secure with lock washers and nuts. Tighten
securely after all bolts are inserted.
F) Lift the top discharge section, install, and bolt together in the same manner as described in the previous step. Discharge air outlet
screens should be positioned for air flow direction as recommended by the Thermo-Cycler Representative or Dealer.
G) Check to make sure that all bolts, nuts, screws, and other parts are secure and have not loosened in transit or during installation.
H) Put the bag containing the time clock pins in the control cabinet for later installation during startup.
I) Connect electric power service to the main switch in accordance with all applicable local codes and regulations. In the absence of
local codes, the installation must be installed in accordance with the latest edition of the National Electric Code (NFPA Standard 70),
the Installation, Operation, and Maintenance Manual furnished with the unit, and the wiring diagram located on the inside cover of the
control panel. A separate electric power circuit is recommended. All control wiring is factory installed within the Thermo-Cycler.
J) Reconnect the flexible electric conduit from the control cabinet mounted on the base fan section, to the electric junction box
mounted on the center heat exchanger section. Reconnect the color coded numbered wires with the wire connectors provided in the
junction box. Reconnect matching colors and numbers for proper burner and limit control operation.
K) Provide properly sized gas piping in accordance with local codes and gas utility company regulations. In the absence of local
codes, the installation must be installed in accordance with the latest edition of the National Fuel Gas Code (NFPA Standard 54) and
the Installation, Operation, and Maintenance Manual furnished with the unit. Gas piping should be adequately sized so that gas
pressure provided at the unit must be between 7" W.C. to 14" W.C. For gas line pressures in excess of 14" W.C., the contractor
MUST provide a properly sized gas pressure regulator to reduce the gas pressure. Properly support gas piping to prevent strain on
the burner gas valve connection.
L) Attach a properly sized flue gas vent to unit in accordance with all local codes and regulations using approved venting materials
and maintaining clearance to combustible materials in compliance with the type of venting materials selected. In the absence of local
codes, the installation must be completed in accordance with the latest edition of the National Fuel Gas Code (NFPA Standard 54) and
the Installation, Operation, and Maintenance Manual furnished with the unit.
M) The Thermo-Cycler has a 4" x 14" collar for combustion air intake located on the burner cover enclosure. The combustion air may
be directly connected and ducted to the outside wall if required by local codes or project conditions. Some conditions where ducted
connection may be advisable include: 1) Negative building pressure condition due to operation of exhaust fans or other processes. 2)
Possible presence of any corrosive gases such as chlorine, fluorine, halogen or refrigerant gases which could result in premature heat
exchanger failure. 3) Dusty or dirty atmosphere which could result in improper burner operation.
N) Although each Thermo-Cycler is test fired at the factory, for proper operation and efficiency the unit should be started, tested, and
adjusted for actual project conditions in accordance with the instructions provided in the Installation, Operation, and Maintenance
Manual furnished with the unit.
