ClimateMaster Water-Source Heat Pumps
Console (CCE) Series
0.5 to 1.5 Ton Console Units
Piping:
Water piping shall terminate in the same location regardless of the connection and valve options.
Option: Threaded EPT copper fi ttings (sweat connections are standard).
Option: Threaded IPT copper fi ttings (sweat connections are standard).
Drain Pan:
The drain pan shall be constructed of galvanized steel and have a powder coat paint application to further inhibit corrosion.
This corrosion protection system shall meet the stringent 1000 hour salt spray test per ASTM B117. If plastic type material is
used, it must be HDPE (High Density Polyethylene) to avoid thermal cycling shock stress failure over the lifetime of the unit.
Stainless Steel materials are also acceptable. Drain pan shall be fully insulated. Drain outlet shall be located at pan as to
allow complete and unobstructed drainage of condensate. The unit as standard will be supplied with solid-state electronic
condensate overfl ow protection. Mechanical fl oat switches will NOT be accepted.
Electrical:
Unit controls shall be located under the hinged control door in the sloped top grille. Operating controls shall consist of slide
switches to select “OFF”, “HEAT,” “COOL,” “AUTO” (when equipped with auto change-over option – “AUTO” is not available
for standard manual change-over controls), Fan “AUTO” (fan cycles with compressor), Fan “ON” (continuous fan), Fan “LO”
(low speed fan), and Fan “HI” (high speed fan). Temperature adjustment shall be accomplished via two push buttons, one
labeled with an arrow up, and the other labeled with an arrow down. Controls shall include an LCD display for display of
temperature and set point. Units without an LCD display shall not be accepted.
A control box shall be located above the unit compressor compartment and shall contain operating controls as outlined in the
paragraph above, 24VAC transformer, double-pole compressor relay, and solid-state controller for complete unit operation.
Reversing valve and fan motor wiring shall be routed through this electronic controller. Units shall be name-plated for use with
time delay fuses or HACR circuit breakers. A unit-mounted digital thermostat with a remote bulb measuring return air temperature
shall control the compressor operation for heating and cooling. Control shall be equipped with a fan switch (provides options to
cycle fan with compressor or provide continuous fan) and a fault indicator light. Units without a fault indicator light shall not be
accepted.
Option: Digital ACO unit mounted thermostat (MCO is standard).
Option: Provisions for remote thermostat (unit mounted is standard).
Option: Disconnect Switch, Non-Fused.
Option: Disconnect Switch, Fused with 15A fuse.
Option: 20A power plug/cord.
Option: 20A plug, cord, receptacle, disconnect switch, fused with 15A fuse.
Option: 20A plug, cord, receptacle, disconnect switch, non fused.
Solid State Control System (CXM):
Units shall have a solid-state control system. Units utilizing electro-mechanical control shall not be acceptable. The control
system microprocessor board shall be specifi cally designed to protect against building electrical system noise contamination,
EMI, and RFI interference. The control system shall interface with a heat pump type thermostat. The control system shall have
the following features:
a. Anti-short cycle time delay on compressor operation.
b. Random start on power up mode.
c. Low voltage protection.
d. High voltage protection.
e. Unit shutdown on high or low refrigerant pressures.
f. Unit shutdown on low water temperature.
g. Condensate overfl ow electronic protection.
