Filters, Throwaway; Replacement Parts - IEC Vertical F*C Series Installation, Operation & Maintenance Manual

to maintain the equipment in compliance with governing
codes, ordinances and testing agency listings.
More specific information regarding the use and operating
characteristics of the standard controls offered by the
manufacturer are contained in other manuals.
Valves and Piping
No formal maintenance is required on the valve-package
components most commonly used with fan coil units other
than a visual inspection for possible leaks in the course of
other normal periodic maintenance. In the event that a
valve must be replaced, the same precautions taken during
the initial installation to protect the valve package from
excessive heat should also be used during replacement.

Filters, Throwaway

The type of throwaway filter most commonly used on fan
coil units shall be replaced on a regular basis. The time
interval between each replacement shall be established
based on regular inspection of the filter, and should be
recorded in the log for each unit. Refer to the product
catalog for the recommended filter size for each product
type and size. If the replacement filters are not purchased
from the factory, the filters used should be the same type
and size as those furnished from, or recommended by the
factory. Pleated media, or extended surface filters shall
not be used since the high air pressure drops encountered
with these types of filters is not compatible with the type
of fan coil unit covered in this manual. Consult the factory
for applications using filter types other than the factory
standard or optional product.
Filters, Permanent
A maintenance schedule for permanent filters shall be
developed in the same manner as throwaway filters. Unlike
throwaway filters, permanent filters may be cleaned and
reinstalled in the unit instead of being discarded when dirty.
The optional factory permanent filter may be cleaned in hot
soapy water to remove any trapped dirt then set aside on
edge to dry.

INSTALLATION, OPERATION, & MAINTENANCE MANUAL
Before replacing the filter in the unit, it should be recharged
with some type of entrapment film such as "Film Cor
Recharging Oil. " The filter shall be sprayed on both sides or
submerged in the film to assure complete coverage. The
filter should not be allowed to soak in the film, but should
be immediately removed and the excess film drained from
the filter before reinstallation in the unit. Consult a local
filter supplier for types of available cleaning solutions and
charging films.
Note that permanent filters normally have less static
pressure loss than throwaway filters.
Drain
The drain shall be checked before initial startup, and at the
beginning of each cooling season to assure that the drain
trap, and line are clear. If it is clogged, take steps to clear the
debris so that condensate will flow easily.
Make periodic checks of the drain during the cooling season
to maintain a free-flowing condensate. Units provided with
a secondary or "tell-tale" drain connection will indicate
a clogged main-drain line by flow from the "tell-tale"
connection.
Should the growth of algae and/or bacteria be a concern,
consult an air conditioning and refrigeration supply
organization familiar with local conditions for chemicals, or
other solutions available to control these agents.
