WARNING: Disconnect primary power prior to servicing.
Maxiva ULX COFDM Series
If a system leak, is detected around a plumbed solder joint, the coolant should be
drained, the leak point resoldered, and the system refilled and tested.
Repairs for a leak originating at a threaded joint may be initially attempted by
tightening the affected joint without draining the system. If this tightening effort does
not correct the problem, then the system must be drained, the problem area opened and
replumbed as necessary, followed by a system refill and test.
b.
Probably the single most important maintenance step: Inspect the bottom of the
heat exchanger bi-monthly. Inspect the coil itself for any debris that may have
become trapped on the coil face. This would block air flow and decrease cooling
efficiency of the heat exchanger. Debris can be removed using a hose and
pressurized water system. In dusty environments or areas where an abundance of
vegetation is present this inspection will be required weekly
c.
To achieve even usage time per unit and ascertain that back-up integrity exists, it
is recommended that the pumps in the pump module are operated alternately one
month at a time.
a.
Check the pump module pressure gauge to ensure that a consistant stable pressure
is indicated.
b.
Inspect and clean the filtration loop.
c.
Check flow rate.
d.
Per the comment included in B.2.3 Standard Coolant Plumbing Practices section,
mandate a continual discipline of NOT allowing plumbing pipe, fittings, etc., to
be walked on.
e.
The system must be analyzed for glycol concentration, annually. Analysis can be
provided by the glycol manufacturer or via use of an analytical test kit supplied
through the manufacturer.
f.
See Transcool documentation for detailed maintenance instructions.
B.3.1 Reserve Coolant Supply
A sufficient reserve supply of coolant and corresponding deinonized water should be
kept on hand to refill the entire system in the event of a major leak.
B.3.2 Clean-Up Plan
A plan for containment and spill clean-up acceptable to local environmental regulations
should be considered.
