Two plumbing adapters (¾ inch MPT x
5
/8 inch hose) are included with the
unit. If the unit is being plumbed to the instrument being cooled using flexible
tubing, install the adapters in the SUPPLY and RETURN plumbing ports. To
prevent leaking, wrap the threads of the adapters with Teflon
®
sealing tape
before installing them in the plumbing ports. The adapters will accept ½ or 5/8
inch ID flexible tubing.
If the unit is "hard plumbed” to the instrument being cooled or to the cooling
water supply, damage can occur if the unit is bumped or jolted from its site.
Provisions should be made to prevent the unit from being moved after
installation. Once the unit is plumbed, secure the locking castors on the
unit’s base. If the unit is located in a heavy traffic area where the possibility
of collision is imminent, it may be necessary to secure the unit to the site
using blocks or mounting brackets.
Flexible tubing, if used, should be heavy wall or reinforced construction. All
tubing should be rated to withstand 110 psi at +35°C. Make sure all tubing
connections are securely clamped. Avoid running tubing near radiators, hot
water pipes, etc. If substantial lengths of tubing are necessary, insulation
may be required to prevent loss of cooling capacity.
Tubing and insulation are available from NESLAB. Contact our Sales
Department for more information (see Preface, After-sale Support).
It is important to keep the distance between the unit and the instrument
being cooled as short as possible, and to use the largest diameter tubing
practical. Tubing should be straight and without bends. If diameter
