Cassette Plumbing - Dimplex CDFI500-PRO Installation And User Manual

Installation

Cassette Plumbing

CAUTION: Ensure that all plumbing connections meet local plumbing code requirements.
CAUTION: Ensure that the location of the plumbing connection allows for easy access to allow for shutoff during
scheduled maintenance.
The units come equipped with refill containers for manual filling of the reservoir. The unit can be hard plumbed with
the plumbing accessory kit - CDFIPLUMB-KIT, available from your local Dimplex dealer, or with standard ¼" (6.4mm)
tubing. The plumbing accessory kit is designed for use with copper piping.
1. Locate a cold water line in the vicinity of the desired location of the cassette.
!
NOTE: Normal tap water can be used in the Opti-myst
water. In the event your tap water is hard, softened or filtered water is recommended.
2. Turn off the main water supply and drain the line of any standing water (if possible), before connecting the water
line.
!
NOTE: Once the new plumbing connections are complete, ensure that the lines are flushed to prevent any debris
from entering the unit.
3. Replace the top cover assemblies and ensure that the two plumbing caps are securely attached to the top cover
of the water reservoirs. (Figure 13, page 16)
4. Locate the ball valve located in the bottom center of the unit (near the back) (Figure 5). Attach one end of
the ¼" (6.4 mm) tubing to the ball valve. Insert the tubing into the ball valve fitting so that it is fully inserted
(approximately ½" [12 mm]).
!
NOTE: Ensure that the end of the tubing is cut square, to prevent leaking.
5. Route the tubing to the area of the water source.
6. Verify that all of the connections are fully inserted, and begin opening each of the valves, ensuring that no leaks
are present.
Connecting Multiple Units Together
When connecting multiple units together, the plumbing should be constructed in a manifold style configuration,
sized appropriately for the number of units that are being installed so consistent water volume and pressure is being
supplied to each unit.
