DELTA SYSTEM OWNER INSTALLATION MANUAL
Important general points
a. Do not route water pipes across service access panels, filter access or duct
connections.
b. The water circuits to and from the Delta should be capable of maintaining
water flow within the specified limits. (See section 5.0 DATA SHEET on
page 61.)
c. All pipe work must be adequately supported with allowance for expansion
and contraction especially with regard to the plastic pipe work.
d. It is recommended that when installing water systems the last connections
to be made should be adjacent to the Delta to avoid undue stresses on
the internal pipework.
e. All pool Purifying Devices and Chemical Injection Systems must be
fitted down stream of the Delta unit with a non-return valve to prevent
concentrated chemicals back feeding into the heat exchangers.
The practice of dosing chemicals direct into the Skimmer Basket which
results in concentrated corrosive liquids passing over vulnerable metal
components must not be allowed.
f. Water quality must be maintained not only relating to solids, etc. but for pH
between 7.4± 0.4, (and if pool water is saline at a maximum concentration
of 3% wt/wt). See 8.0 WARRANTY CONDITIONS for total list of water
quality limits.
3.4 PLUMBING INSTALLATION
a. The condensate drip tray at e base of e Delta collects e water
removed by e dehumidification process. Ensure e Delta is placed on
a level plin so at e condensate can run away and not overflow e
edges of e drip tray inside e machine.
b. All Delta models have a ¾” BSPM readed condensate drain connection.
The drain pipe should be run away wi e adequate fall to waste i.e. ½”
per minimum. DO NOT fit a trap as it is a standard fitting inside e unit.
An air break or tun dish should be incorporated to prevent back flow of foul
water and smells. (See Fig 3.1 on page 44.)
LPHW plumbing
a. Delta 1 and 2 have 28mm copper stubs. Delta 4, 6 and 8 wi standard
LPHW have 28mm copper stubs. Delta 4, 6 and 8 wi upgraded LPHW
have 35mm copper stubs. Delta 10 and 12 have 35mm copper stubs.
Delta 14 and 16 wi standard LPHW have 1½” BSPM. Delta 14 and 16
wi upgraded LPHW have 2” BSPM..
b. Suitable breakable couplings, isolation and drain down valves should be
installed in e boiler water flow/return pipes local to e Delta unit.
c. A mixing valve and/or bypass may be required to maintain a minimum
boiler return temperature and/or keep a constant load to e boiler pump.
Refer to e boiler manufacturers instructions before designing e pipe
work system.
d. If boiler and water pump is not controlled by Delta en a boiler bypass will
be required.
e. A flow meter should be fitted (or pressure gauges).
f. A filter or “boiler buddy” should be added to e pipe work to help keep
e heat exchangers in e Delta free from blockages.
Pool water
a. The Delta must be connected into e pool filtration water circuit, aer
e pump and filter. If an existing heater is being retained, en e Delta
should be connected upstream of e existing heater (see following
schematics), or in parallel.
b. The Delta has plastic stubs (solvent weld) for connecting e pool water
flow and return. On Delta 1 to 8 ese stubs are 1" diameter. On Delta 10
to 16 ese stubs are 1½".
c. Suitable breakable couplings, isolation, and drain down valves should be
installed in e pool water flow and return pipes.
d. The Delta may, on small pools, take e full flow rate of e pool filtration
system. On larger pools, or if e pool flow rate does not match, a bypass
or separate auxiliary pump may be necessary. This meod can also be
used to reduce energy consumption, by e installation of a two speed
or auxiliary pump by-passing e main pump/filter to satisfy pool water
heating and dehumidification wiout e need for e main pump to
be running. Furer savings on bo e above meods can be made
by utilizing e standard feature on all Delta units to control e main or
auxiliary pumps. (See page 51.)
e. When e pipe work installation is complete e circulating pump(s)
should be switched on and e system checked for leaks. Check e filter
gauge to see at ere is not excessive back pressure.
f. A flow meter should be fitted (or pressure gauges).
